NVIDIA Becomes First Public Company to Reach $4 Trillion Market Cap, Driven by AI Infrastructure Demand
On July 9, 2025, NVIDIA reached a market capitalization of $4 trillion for the first time as a public company due to a rise in its stock price, symbolizing the investment fervor in AI infrastructure. At the same time, SpaceX is in negotiations to sell insider shares, which suggests a valuation of $400 billion. This article covers key topics for both companies and explores their backgrounds and future outlooks.
1. NVIDIA's Historic Milestone: Reaching a $4 Trillion Market Cap
1-1. Trends in Market Valuation
NVIDIA's stock price rose again after a correction phase in early 2025, surging to a temporary high of $164.42 on July 9 and breaking through the $4 trillion market cap threshold. This milestone helped push the NASDAQ Composite Index to a record high, providing a tailwind for technology stocks in general.
1-2. Growth Factors: Demand for AI and Data Centers
NVIDIA supports training and inference infrastructure for generative AI models through its high-performance GPUs, and demand for data centers from major clients such as Amazon, Microsoft, and OpenAI is surging. In particular, production of the Blackwell generation of chips is reported to be sold out through the end of 2025, and supply is expected to remain tight for the foreseeable future.
1-3. Risk Factors: Bubble Concerns and Regulations
Some point out that the rapid rise in stock prices is reminiscent of the dot-com bubble of the past, and research from Harvard University indicates a tendency for the risk of a crash to increase after a sharp surge. Additionally, depending on the trends in US-China trade friction and AI regulations, temporary selling pressure could intensify.
2. SpaceX's Fundraising and the Path to a $400 Billion Valuation
2-1. Overview of the Insider Share Sale Plan
SpaceX is considering an insider share sale to liquidate shares held by founders and employees after discussions with multiple parties, and is exploring terms that would value the company at approximately $400 billion. The scale of the negotiations is said to be in the billions of dollars, with the final sale percentage and price left to future adjustments.
2-2. Impact on Corporate Value
If this share sale is realized, SpaceX will be positioned at the highest level in history for a private company's valuation, which is expected to lower barriers to entry for new investors and improve liquidity. However, there are concerns about the dilution of founder shares, and the focus will be on governance and the maintenance of management control by existing shareholders.
2-3. Fundraising Trends in the Space Industry
SpaceX expects revenue of approximately $15.5 billion in 2025, with commercial launches and Starlink communication services driving earnings. Meanwhile, investment competition for space startups, in which government-backed funds from the West and the Middle East are also participating, is intensifying, and the total amount of capital flowing into the market is on an upward trend.
3. Impact on the Market and Future Outlook
3-1. Investor Sentiment and Portfolio Strategy
Investors are increasing their allocation to infrastructure-related AI stocks like NVIDIA while seeking to expand access to private companies like SpaceX. From a risk management perspective, they will likely consider hedging strategies while adjusting their tech stock ratios.
3-2. Impact of Regulations and Trade Friction
While there is some "regulatory fatigue" among companies as the Trump administration suggests high tariffs on key resources such as semiconductors and copper, short-term volatility may increase depending on the final content of any agreements.
3-3. The Future of the AI and Space Industries
The supply-demand tightness for AI infrastructure is expected to continue, and chip design giants like NVIDIA are projected to maintain their market leadership. In the space sector, beyond SpaceX, Blue Origin and emerging startups are preparing for funding rounds, which is expected to accelerate competition in next-generation launch technology and the construction of satellite communication networks.
As described above, NVIDIA reaching $4 trillion and SpaceX negotiating a $400 billion valuation provide investors with new perspectives while strongly suggesting shifts in market structure. It will be necessary to reconsider appropriate risk management and investment strategies while keeping a close watch on future regulatory trends and technological innovations.
