The Truth Behind the 16% Drop in SpaceX Stock: The Hype of the Largest IPO Cools, and a 3.2 Trillion Yen Bond Issue Reveals the Reality of AI Funding

Just over 10 days since its initial public offering (IPO), SpaceX, a company that has captured the world's attention, saw its stock price fall by as much as 16% on the U.S. stock market on June 22, 2026. It easily dipped below its closing price from the first day of trading, marking its third consecutive day of decline. On the same day, the company announced a massive bond issuance plan—one befitting a company with a market capitalization exceeding $2 trillion, or perhaps even one that could swallow it whole. The goal is to refinance high-interest debt incurred for its artificial intelligence (AI) business with the lower-cost credit of a publicly traded company. Elon Musk's ambition to run two massive businesses—space and AI—simultaneously, along with the reality of his financing, is being forced upon the market in the form of volatile stock prices. In this article, we will carefully track what happened using the numbers, decode the details of the bond issuance that triggered the sharp decline, the creditworthiness indicated by its ratings, and the structural weakness of its 5% free float, all from the perspective of general business professionals and investors.

1. What Happened: Tracking the Volatility of SpaceX Stock with Numbers

First, let's confirm what actually happened in the market on June 22 using a chronological breakdown of the numbers.

Shortly after 3:30 PM Eastern Time, SpaceX stock hit the $155 range, down 16% from the previous trading day. On the same day, the Nasdaq Composite Index, which has a high proportion of tech stocks, was also down 1%, but compared to that, the scale of SpaceX's decline was exceptionally large. It is clear that selling was concentrated on the SpaceX ticker itself, beyond just the market being slightly soft.

This is where the price movement since the IPO comes into play. On June 12, the first day of trading, SpaceX closed at $160.95, up 19% from its offering price. As an initial surge following an IPO, it appeared to be a smooth start.

However, the frenzy accelerated from there. On the second trading day, the stock continued to rise, hitting a high in the $225 range at one point. That is an increase of about 40% from the offering price. A typical overheated market where funds rush into newly listed stocks was evident here.

The tide turned after June 17. The stock price began to fall from its high in the $225 range, and on June 22, it finally dipped below the first day's closing price of $160.95. In other words, among individual investors who bought immediately after the listing, even those who bought at the first day's closing price were now holding unrealized losses. The continuity of three consecutive days of decline also reflects the market's anxious sentiment.

The article points to profit-taking by individual investors who participated in the IPO as the background for this decline. It is believed that the move to lock in unrealized gains that had swelled at the $225 level contributed to pushing the stock price down. For newly listed stocks, this is an adjustment that almost inevitably occurs when early investors lock in profits and the overheated supply-demand balance settles.

Just to be sure, let's look back at the magnitude of the IPO event itself. SpaceX's listing was expected to be the largest IPO in history, and market participants around the world had been paying attention to it even before it went public. A company that had grown to a massive enterprise value of around $2 trillion while remaining private finally opened the doors to the stock market. The high level of attention generated a rush of individual investors from the first day of trading, triggering the overheating that led to the $225 range on the second day. The greater the expectations, the more intense the reactionary adjustment. The roughly 30% drop from the $225 range to the $155 range can be categorized as a typical reaction that occurs in the process of overheated expectations cooling down.

For newly listed stocks, it is a common pattern for the stock price to move significantly immediately after listing and then, after a while, converge to a level commensurate with the company's intrinsic value. In that sense, no one yet knows whether the $155 range as of June 22 is SpaceX's "fair stock price." It has only been a little over 10 days since the listing. It can be said that the market is still in the stage of groping for how to price this giant company.

However, one thing to keep in mind here is that this decline cannot be explained solely by supply and demand adjustments. On the 22nd, a factor that directly shook the stock price—the announcement of a large-scale bond issuance plan—coincided with the decline. In the next chapter, we will look at the details of these bonds.

2. The Trigger for the Sharp Decline: A 3.2 Trillion Yen Large-Scale Bond Issuance Plan

On June 22, SpaceX announced a large-scale bond issuance plan. The company held a conference call with investors on the same day, and according to Bloomberg, the funding target is $20 billion, which amounts to over 3.2 trillion Japanese yen. This is an extremely large amount for a single company to raise in one go.

Let's look at the magnitude of this $20 billion figure from a slightly different angle. SpaceX's market capitalization is said to be around $2 trillion. The amount raised this time is equivalent to about 1% of that market capitalization. They are attempting to raise debt equivalent to 1% of the value of their outstanding shares from the bond market all at once. This shows their stance of immediately utilizing the credit and name recognition gained from the IPO to the fullest extent for fundraising.

So, what will this massive amount of money be used for? SpaceX explained that the proceeds will be used primarily for bridge loans, or refinancing. It is not for new capital investment or for launching new businesses. Replacing already borrowed funds with a different form of debt—so-called refinancing—is the main objective.

This is the crux of the news. What many investors reacted to was not the fact that SpaceX was raising funds by issuing bonds, but that the funds would be used to cover debt in areas like AI business and social media operations, which are not necessarily profitable. The fact that the article's headline expresses it as "dislike for raising AI funds via bonds" points to the market's aversion to this exact structure.

It is likely no coincidence that the stock price decline and the announcement of the bond issuance plan occurred on the same day. It is natural to read that the supply-demand factor of profit-taking immediately after the IPO was compounded by the material factor of concerns over AI financing, which amplified the scale of the decline. For investors, the stock they bought in anticipation of the growth of the space business turned out to be directly linked to fundraising to cover the losses of an AI business. It is thought that this gap invited the selling.

Let's also organize what a bond issuance means for the stock. In general, a company issuing large-scale bonds means it is taking on that much more debt. If debt increases, the burden of interest payments increases, and financial risk rises. From a shareholder's perspective, the expansion of a company's liabilities is not necessarily something to be welcomed. This is especially true if that debt is not for new growth investment, but for filling the hole of debt from already loss-making businesses. While this bond issuance is a rational move to rebuild finances, it also had the effect of making the market re-recognize the fact that SpaceX was carrying heavier debt than imagined. This renewed awareness of the "weight of debt" is also seen as a factor that pushed down the stock price.

Why does SpaceX need to issue bonds so urgently? The answer lies in the structure of the borrowing that existed behind the IPO.

3. Why Bonds? The $20 Billion Bridge Loan to be Repaid Within Six Months of the IPO

The reason SpaceX is rushing to issue corporate bonds lies in its contract with a banking syndicate. The company is required to repay a $20 billion bridge loan within six months of its IPO.

A bridge loan is, quite literally, a short-term loan used as a "bridge." It is used to temporarily cover funding needs until full-scale financing is arranged. In the case of SpaceX, it appears they set up a plan to first borrow $20 billion from a banking syndicate to facilitate the major funding event of an IPO, and then repay this after going public using formal financing methods. The repayment deadline is now approaching, set as "within six months of the IPO."

So, why did SpaceX need to borrow as much as $20 billion in the first place? The key lies in the debts of two companies that Mr. Musk has brought under his umbrella.

One is X, formerly Twitter. X has approximately $12.5 billion in debt. The other is xAI, which carries approximately $5 billion in debt. Combined, that is about $17.5 billion. When adding the funding needs associated with this, it leads to a calculation of borrowing on the scale of $20 billion.

The problem was the interest rates on these debts. According to the article, the borrowing interest rates for X and xAI were around 10%, meaning interest payment costs were high. An annual interest rate of 10% is a considerably high level in the current market environment. If 10% interest is applied to $17.5 billion, it calculates to an annual burden of over $1.7 billion, or approximately 270 billion yen. If this much in interest payments is going out every year, it significantly pressures the business's earnings.

The strategy SpaceX devised was to leverage its creditworthiness as a publicly traded company to refinance into corporate bonds with lower interest rates. Funds borrowed individually by a private startup tend to have high interest rates because the risk is high from the lender's perspective. However, with corporate bonds issued by a publicly traded company with a market capitalization of $2 trillion, funds can be raised from the market at much lower interest rates. By replacing high-interest bridge loans and existing debt with low-interest corporate bonds, they can significantly reduce interest payment costs. This is the economic objective of this corporate bond issuance.

In other words, this corporate bond issuance can be understood as having more of a defensive character to shore up financial health rather than being an aggressive fundraising move. They are using the event of going public not just as a place to raise funds through stocks, but as a mechanism to instantly refinance high-interest debt into low-interest debt. It can be said that this is a bold and rational financial design, typical of Mr. Musk.

Here, I will add a little context on how the two companies, X and xAI, are connected to SpaceX. X is the former Twitter that Mr. Musk acquired and is now the core social media platform of his business group. xAI is an AI development company launched by Mr. Musk that is advancing the development of conversational AI and other technologies. While these were originally separate companies from SpaceX, capital and funds are intricately intertwined within Mr. Musk's business empire. The structure where SpaceX is taking on these debts shows that the multiple companies led by Mr. Musk are effectively within a single circulation of funds.

This intertwining of funds is both a strength and a weakness. As a strength, the creditworthiness of the profitable SpaceX can be utilized for the fundraising of X and xAI, which are not yet profitable. Looking at the group as a whole, the company with the highest creditworthiness can raise funds cheaply and circulate them within the group, thereby increasing overall capital efficiency. On the other hand, as a weakness, there is a risk that the poor performance of one business could spill over into the finances of another. If the deficits or debts of X and xAI pressure the finances of SpaceX, which is the pillar of earnings, it could also affect the investment capacity of the space business itself. This corporate bond issuance also has the aspect of making the market aware of this risk of interdependence.

However, whether this refinancing succeeds depends on how much high credit SpaceX can obtain in the market. The yardstick for that credit is the ratings provided by credit rating agencies.

4. Creditworthiness Reflected in Ratings: Baa1, Triple B Plus, and Triple B

Whether corporate bonds can be issued at a low interest rate depends heavily on how credit rating agencies evaluate the issuer. This time, SpaceX obtained ratings from each of the world's three major credit rating agencies.

From the major US rating agency Moody's Ratings, it received a "Baa1," which is equivalent to a Triple B Plus rating. From Fitch Ratings, it received a straight "Triple B Plus" rating. These two companies' evaluations place it third from the bottom within investment grade. On the other hand, S&P Global Ratings gave it a "Triple B," which is one notch lower.

Here, I will briefly organize the meaning of credit ratings. Ratings are broadly divided into two areas: investment grade and speculative grade (so-called junk grade). Investment grade refers to a level where conservative institutional investors such as pension funds and insurance companies can invest with peace of mind. Conversely, if it falls into speculative grade, the pool of investors who can invest narrows significantly, and the procurement interest rate jumps up.

The "Triple B Plus" and "Triple B" that SpaceX received both remain in the investment-grade territory. Although it is a lower-tier evaluation within investment grade—third from the bottom or second from the bottom—it is not junk grade. This is critically important for the refinancing of corporate bonds. Because they were able to secure investment grade, they have the prospect of issuing $20 billion in corporate bonds at relatively low interest rates to a wide range of institutional investors.

Conversely, if SpaceX had remained at junk grade, this refinancing strategy itself would have been difficult to realize. The high interest rate of around 10% for X and xAI was precisely the interest rate for a startup that is not publicly traded and lacks the backing of creditworthiness. By refinancing that into investment-grade corporate bonds, the interest rate can be significantly lowered. For example, if an interest rate of 10% were to drop to around 5%, it could lead to an interest payment reduction of over $800 million annually on $17.5 billion, or approximately 130 billion yen. This is an effect that cannot be ignored in mitigating the deficit of the AI business.

However, being in the lower tier of investment grade also means, in other words, that it is in a state of "barely maintaining investment grade." If the business environment deteriorates or the burden of AI investment expands further, one cannot say there is no risk of a downgrade. A downgrade leads directly to an increase in procurement interest rates, which diminishes the benefits of the refinancing. A rating is not something that is finished once obtained; it moves according to subsequent performance and financial trends. As investors, while accepting this rating acquisition positively as proof of creditworthiness, it is necessary to continue to monitor future rating trends.

The fact that the ratings from the three companies are slightly split is also worth noting. While Moody's and Fitch rated it as equivalent to Triple B Plus, S&P rated it one notch lower at Triple B. It is not unusual for evaluations to differ by rating agency, but where S&P, which made the most cautious evaluation, had concerns is an important hint for investors. In general, companies with complex businesses that have a mix of loss-making and profitable divisions are difficult to evaluate. How stable the earnings power of the space business is viewed, and how much the deficit and debt of the AI business are viewed as risks—it is thought that the difference in these assessments is expressed as a one-notch difference in rating.

Corporate bond investors will judge at what interest rate they will buy SpaceX's corporate bonds while referring to these ratings. As long as the rating can maintain investment grade, SpaceX can raise funds under favorable conditions because broad demand from institutional investors can be expected. At what interest rate level will this $20 billion issuance be absorbed? That will be another answer to how the market ultimately priced SpaceX's creditworthiness.

5. Structural Factors of Volatility: 5% Free Float and Lock-up Expiration

So far, we have looked at the issuance of corporate bonds as the trigger for the stock price decline, but we cannot overlook the fact that SpaceX stock has a structure that is inherently prone to volatility. The key is the concept of the free-float ratio.

SpaceX has a market capitalization of around $2 trillion, putting it on par with major US tech companies. However, the reality is that the ratio of free-float shares—those actually available for trading in the market—is extremely low, at approximately 5%. In other words, despite its large market capitalization, the amount of stock circulating and freely traded in the market is very small.

What happens to a stock price when the free float is low? The answer is simple: it becomes prone to wild fluctuations. Because the amount of stock available for trading is limited, a slight increase in buy orders causes the stock price to jump, while a slight increase in sell orders causes it to plummet. Small changes in supply and demand are amplified and reflected in the price. The roller-coaster price movement, which surged to the $225 range on the second day of listing and then plunged to the $155 range, is thought to be partly due to this low free float. If buying concentrates, it rises all at once, and if profit-taking selling occurs, it falls all at once. This is the fate common to stocks with low liquidity.

Furthermore, this free-float ratio will take on even greater significance in the future. This is because the restrictions on stock sales imposed on existing shareholders, known as lock-ups, will be gradually lifted from here on out.

A lock-up is an agreement made at the time of an IPO that prevents existing shareholders, such as founders and early investors, from selling their shares for a certain period. It is a mechanism to prevent the stock price from collapsing due to a large volume of selling immediately after listing. In the case of SpaceX, these lock-ups are scheduled to be lifted in stages, and the number of shares circulating in the market will increase with each lifting. In other words, the free float, which was only 5% until now, will increase each time a lock-up is lifted, changing the supply-demand balance.

According to the article, the lifting of lock-ups is expected to begin after the earnings announcement for the April-June 2026 period, which is anticipated to take place between late July and early August. A major event like an earnings announcement will be followed by the supply-demand deterioration factor of the lock-up expiration. If selling by existing shareholders increases at this timing, there is a possibility that downward pressure will be applied to the stock price. The risk scenario pointed out by the article is that the market may face a phase where it becomes conscious of this supply-demand deterioration.

For investors, this period from late July to early August will be a key point to watch. In addition to the content of the earnings themselves, how many shares will enter the market due to the lock-up expiration, and how the market will digest them, are important. Precisely because it is a stock with a low free float, the impact of the newly circulating shares on the stock price will be significant. The 16% drop this time can be read as a manifestation of one aspect of these structural supply-demand risks, triggered by the material of the corporate bond issuance.

There is another aspect of having a low free float that cannot be overlooked. That is the fact that the stock price is prone to becoming higher than the actual situation warrants. If buying demand concentrates while there are few shares available to trade, the stock price will rise significantly even with a small amount of buying. In other words, the high stock price immediately after listing does not necessarily accurately reflect the company's true strength. The high of $225 may have been a temporary level created by overheated supply and demand. As lock-ups are lifted and the free float increases, supply and demand are expected to normalize, and the stock price is expected to converge to a level closer to the company's intrinsic value. In that process, there is a strong possibility of a phase where the stock price adjusts downward. This current adjustment may just be the entrance to that long normalization process.

As investors, rather than judging whether a stock is cheap or expensive based solely on the current stock price level, it is necessary to adopt a stance of calmly estimating corporate value while incorporating the future supply-demand environment where the free float will increase. This is because stock prices at a stage of low liquidity have high volatility and are easily swayed.

6. The Dual-Wielding of Space and AI: A Business Structure Where Satellite Communications Support Loss-Making AI

Here, let's organize what kind of business structure SpaceX has in the first place. Without understanding this business structure, the essence of both this corporate bond issuance and the stock price volatility cannot be seen.

SpaceX is a conglomerate that handles multiple businesses simultaneously. The pillars are three: the rocket launch business, the satellite communications business, and the artificial intelligence (AI) development business. In rockets, it has dramatically lowered launch costs through reusable rockets, and in satellite communications, it is deploying satellite internet services represented by Starlink around the world. These space businesses have already grown into profit-generating operations.

On the other hand, the AI development business has a different aspect. The article clearly depicts a structure where the loss-making AI business is supported by the space business. In other words, the profitable space business is financially underpinning the AI business, which has not yet generated profits. Within a single company, profit-making departments and forward-investment departments coexist.

This structure was made even clearer by this corporate bond issuance. The article explains that this corporate bond issuance will take over the debts held by the unprofitable AI and SNS operations. In other words, it uses the creditworthiness earned by the space business to issue corporate bonds, and uses those funds to cover the debts of AI and SNS, namely X. Space earns, and that profit and credit support AI and SNS. This structure of interdependence represents the current position of the company known as SpaceX.

How investors evaluate this structure depends on their position. If viewed optimistically, it can be evaluated as a growth-rich company that is boldly investing in AI, a huge future market, based on the stable revenue foundation of the space business. On the other hand, if viewed cautiously, one can be concerned that the profits of the space business are being sucked up to fill the holes of the loss-making AI and SNS. The stock price drop on June 22 can be said to be the moment when the latter view—that is, concern about AI's funding—became dominant in the market.

The business groups led by Mr. Musk have always been a series of bold bets. Both rocket reusability and global satellite internet were challenges whose realization was initially doubted. Investment in AI is a bet on that same extension. The question is how to procure the funds necessary for that bet and how to keep them circulating. This corporate bond issuance can be positioned as an important move to keep that capital cycle turning.

What we should remember here is that the space business itself, which is the pillar of revenue, is by no means purely stable. Rocket launches always involve technical risks, and satellite communications require global capital investment and operating costs. While the expansion of Starlink subscribers is said to be progressing smoothly, it is still necessary to continuously recover huge capital investments. In other words, there is a corresponding demand for funds and risks on the side of the space business that supports AI. In this situation, taking on the debts of AI and SNS with the creditworthiness of the space business places a not-insignificant burden on the finances of the entire group.

Even so, the reason Mr. Musk tries to maintain this dual-wielding approach is thought to be because he envisions a future where space and AI complement each other. Vast data obtained from satellites, autonomous rocket control and satellite operation by AI, and the computing infrastructure that supports AI development. If these are linked within a single company, a competitive advantage that cannot be imitated by other companies may be born. This series of movements surrounding funding can also be seen as a scene of building a humble but indispensable foundation to realize that grand vision. No matter how the market reacts in the short term, Mr. Musk's gaze is directed toward the fusion of space and AI far in the future.

And regarding this AI business, a new source of revenue is also beginning to move. That is the leasing of data centers.

7. A New Revenue Source: Data Center Leasing

On June 22, alongside news of stock prices and corporate bond issuance, another noteworthy development came to light: SpaceX has signed a contract to lease its data centers to Reflection AI, an emerging AI development company in the U.S.

The details of this contract are specific. It was revealed to the Nikkei that Reflection AI will utilize AI semiconductors at SpaceX's latest facility, "Colossus 2," and will pay $150 million per month starting in July. At $150 million per month, this amounts to approximately $1.8 billion annually, or a transaction scale of 280 billion yen. This demonstrates that leasing out computing resources like data centers can be a significant revenue source.

Moreover, the counterparty is not just Reflection AI. According to the report, SpaceX has also signed similar computing resource provision contracts with U.S.-based Anthropic and Google, both of which are competitors in AI development. Both Anthropic and Google are influential companies developing cutting-edge AI. The fact that SpaceX is leasing its own computing resources to such competitors speaks to how tight and valuable the computing resources—namely AI semiconductors and data centers—required for AI development have become.

Here, the cleverness and the danger of SpaceX's AI strategy coexist.

The clever aspect is that by leasing out computing resources, the AI division has acquired a means to earn money itself. Until now, the AI business was a deficit-ridden department that only incurred costs, but in the form of data center leasing, it will be able to obtain stable monthly income. If a substantial amount of money comes in every month from multiple influential companies, it will contribute directly to improving the AI division's profitability. Reducing interest payments through corporate bonds and increasing income through data center leasing—one can see the move to improve the profitability of the AI business from both financial sides.

On the other hand, dangers are also being pointed out. The article states that leasing computing resources to competitors could lead to delays in in-house development. In AI development, computing resources are the most scarce and important management resource. If those valuable computing resources are leased to competitors, the resources available for the company's own AI development will decrease by that much. As a result of prioritizing immediate revenue and leasing computing resources externally, the company may fall behind in the development race for its own AI models. If that happens, there is a risk that the competitiveness of the AI business itself will be undermined in the long run.

In other words, SpaceX is currently being forced into a trade-off between immediate revenue improvement and future AI development competitiveness. Both financial improvement through corporate bond issuance and monetization through data center leasing are rational choices in the short term. However, will this not become a drag on long-term AI competitiveness? What investors should determine is how SpaceX will balance this short-term and long-term perspective.

This composition is also a microcosm of the AI investment boom currently happening around the world. AI development and operation require vast computing resources and enormous funds to run them. The supply of cutting-edge AI semiconductors is limited, and the construction of data centers also costs a huge amount. That is precisely why we are in an era where those who possess computing resources stand in a strong position and can generate significant revenue just by leasing them out. The reason SpaceX can receive a substantial monthly amount from companies like Reflection AI, Anthropic, and Google, using its latest facility, Colossus 2, as a weapon, is precisely because of this scarcity of computing resources.

Looking at it from another perspective, it can be said that SpaceX is trying to generate revenue not only by competing in the development of AI models themselves but also by positioning itself as a provider of the infrastructure that supports AI development. There is a famous analogy from the Gold Rush era that those who sold pickaxes and jeans, rather than those who dug for gold, were the ones who reliably made money. In the midst of the AI boom, the business of leasing out "pickaxes"—computing resources—has the potential to generate stable revenue regardless of the outcome of the AI model development race. SpaceX's data center leasing can be positioned as one of these "pickaxe-selling" strategies. The problem is that the company itself is also on the side of digging for gold, that is, it is a party involved in AI development. Selling pickaxes to others while digging for gold itself. How SpaceX manages this dual role will determine the success or failure of its AI strategy.

8. How should investors view this? What lies beyond the frenzy

Based on the factors we have looked at so far, I will organize how investors should approach SpaceX stock.

First, it is important to understand that short-term stock price volatility is structurally unavoidable to some extent. The low float of only 5% creates intense price movements where buying concentrates and leads to a surge, while selling leads to a sharp drop. The fluctuation range from the $225 level to the $155 level was a manifestation of this very structure. Profit-taking by individual investors immediately after an IPO is a standard movement for newly listed stocks, and this in itself does not impair the intrinsic value of the company. It is important not to be overly swayed by short-term price movements.

Second, if you also look at how much fruit early investors have reaped, the meaning of the IPO event can be seen in three dimensions. Among the investors who invested in SpaceX in its early stages, some have made significant profits through the listing. As reported, Nippon Life Insurance is said to have earned profits on the scale of hundreds of billions of yen from SpaceX stock, and it has attracted attention as a case where an early investment "hit the jackpot." Investors who took the risk of investing during the private era are rewarded at the exit of an IPO. This is the original function of an IPO and is proof that the mechanism by which risk money fosters innovative companies is working.

Third, keep track of the calendar for future developments. The biggest point is the earnings announcement for the April-June 2026 period, expected around late July to early August, and the lock-up expiration that follows. In addition to the content of the earnings themselves, there is a possibility that the supply-demand balance will deteriorate as the number of shares circulating in the market increases due to the lock-up expiration. Precisely because it is a stock with a small float, the impact of the newly released shares on the stock price will be significant. The trends during this period will likely be a litmus test for looking at SpaceX stock.

Fourth, watch over the long term how the recovery of AI investment progresses. Reducing interest payments through corporate bonds and monetization through data center leasing. If these financial strategies work well, the profitability of the AI business, which was in the red, should gradually improve. However, the company simultaneously carries the risk of delays in in-house development due to leasing computing resources to competitors. Whether the AI business can shed its skin from a deficit-ridden department supported by the space business to a growth department that earns for itself—this will be the biggest variable that influences SpaceX's corporate value in the medium to long term.

SpaceX's IPO is positioned as a symbolic event of the "Great Public Offering Era" of stocks. Companies that have grown huge while remaining private are opening the doors to the stock market one after another, and a battle for funds involving individual investors has begun. SpaceX is a symbolic entity leading the way. That is precisely why its stock price volatility and every move in its fundraising go beyond the story of a single stock and have become a mirror reflecting the future of the market.

Until now, many huge tech companies have continued to grow while remaining private for a long time. This is because abundant funds from the private market flowed in, allowing them to raise huge amounts of capital without going public. As a result, the fruits of the period of greatest growth were reaped by a limited number of investors, such as institutional investors, venture capitalists, and founding members. By the time general individual investors were able to buy the stock, the company was often already mature and past its explosive growth phase. The fact that a huge company like SpaceX is going public means that general investors can finally reach for those closed-off fruits of growth.

On the other hand, going public is also a disclosure of risk. The financial reality, which had been veiled in the private era, is now disclosed every quarter and exposed to the harsh eyes of the market. This corporate bond issuance and stock price decline was an event where that veil was peeled back and the reality of AI funding was exposed to the light of day. Frenzy and risk are two sides of the same coin called going public. For individual investors to face this "Great Public Offering Era," they need to possess both a dreamy growth story and grounded financial analysis.

What remains after the frenzy cools down is the company's business strength and financial soundness. The pillars of revenue from rockets and satellite communications, the bet on the future called AI, and the design of the funding that supports it. The true value of a company called SpaceX is tested not on the glamorous first day of the IPO, but in the steady accumulation of quarters that will follow. What is required of investors is not the momentary numbers such as the high price or sharp drop on the first day, but a perspective that looks toward the long road of how this company will run through its dual-wielding of space and AI.

Summary

The temporary 16% drop in SpaceX stock on June 22, 2026, was caused by a combination of supply-demand factors—specifically profit-taking immediately following the IPO—and concerns over AI funding related to the issuance of 3.2 trillion yen in corporate bonds. The essence of this bond issuance lies in a defensive financial strategy: using the creditworthiness of a publicly traded company to refinance the high-interest debt of around 10% that X and xAI have carried, thereby reducing interest payment costs. Ratings of Baa1 from Moody's, BBB+ from Fitch, and BBB from S&P secured the investment-grade status necessary to make this refinancing possible.

On the other hand, the structure of having a float of only 5% against a market capitalization of $2 trillion makes the stock price prone to volatility, and the lock-up expiration beginning between late July and early August carries the risk of further deterioration in supply and demand. Within a business structure where the space business supports the losses of the AI business, a new revenue stream from data center leasing has begun, but it exists side-by-side with the trade-off of delays in the company's own AI development.

Whether SpaceX can successfully navigate its dual-wielding strategy of space and AI will not be answered on the first day of its IPO, but rather in the quarters that follow. Investors are required to have a perspective that looks toward the long road of business and finance, rather than the stock price of the moment.

The news of this temporary 16% drop might seem like a common story of a popular stock plummeting right after listing if one only follows the headlines. However, inside it are condensed the elements needed to decipher the modern capital market: the frenzy brought about by the largest IPO in history, the precise design of funding for a massive corporation, the battle over investment-grade ratings, and even the structural weakness of a 5% float. The fact that so much of a story is packed behind a single stock price figure speaks to how special a presence SpaceX is in the current market. With the upcoming earnings reports and the lock-up expiration as milestones, I intend to continue watching calmly to see how this grand experiment unfolds.
