Chasing the Herd of Space Unicorns: A New Map of the Space Industry Where Billion-Dollar Startups Converge
The term "unicorn" has become common in economic news. It does not refer to the mythical one-horned creature, but rather to private startups with a valuation of $1 billion (approximately 150 billion yen) or more. In the early 2010s, the person who coined the term intentionally compared it to a "mythical creature" to highlight its rarity, but today, the number of companies holding that title has grown to over 1,300 worldwide.
This trend is now surging into the space industry. SpaceNews, a media outlet specializing in the space industry, has published an article summarizing the current state of space unicorns.
After reading it, I was genuinely surprised. I wondered, have there really been this many in just the last few years? Based on this article, I will organize what is currently happening in the space industry.
SpaceX is now in a "league of its own"
When talking about space unicorns, one cannot start without SpaceX. Its valuation exceeded $800 billion at the end of 2025, and reports regarding its 2026 IPO (Initial Public Offering) have even floated figures as high as $1.75 trillion. This is on par with the scale of Saudi Aramco at the time of its listing (approximately $1.7 trillion), and if it goes public, it could potentially be the largest IPO in history.
In a nutshell, SpaceX's business is "delivery service to space." With its "Falcon 9" rocket service for transporting people and supplies into orbit as its core, the satellite broadband service "Starlink" is growing rapidly as the main pillar of its revenue. I have written before about the future vision of a business centered on Starlink.
In 2025, consolidated revenue reached approximately $18.7 billion (about 2.8 trillion yen), with the Starlink communications division alone accounting for approximately $11.4 billion. The center of gravity for revenue is steadily shifting from rocket launches to communications services. It might be closer to reality to describe SpaceX as a "comprehensive infrastructure company based in space" rather than just a "space company."
A crowded field—a succession of new stars exceeding 100 billion yen
Beyond SpaceX, the number of notable players is increasing rapidly.
Founded in 2022, K2 Space is a startup working on large, high-output satellite platforms. Anticipating an era where large rockets like the Falcon 9, Starship, and New Glenn become widespread, they are betting on the contrarian idea that "satellites should also be larger." This is a reversal of the satellite industry's long-standing focus on "miniaturization and mass deployment." In December 2025, they completed a $250 million funding round, and their valuation jumped to $3 billion at once.
Axiom Space is a company aiming to build the first private commercial space station, with a valuation of approximately $2 billion. As the ISS is scheduled to end operations in 2030, it is attracting expectations as its successor. By winning contracts from NASA for spacesuit development, it is a presence deeply involved in the core of space infrastructure. It also recently made headlines when Japan's largest bank joined as a new investor.
Finland-based ICEYE has a strength in technology that uses SAR (Synthetic Aperture Radar) satellites to observe the Earth's surface regardless of day, night, or weather, and its valuation is approximately $2.8 billion. It is being used for a much wider range of applications than one might imagine, from military reconnaissance and insurance damage assessment to grasping flood damage.
And Sierra Space, which is developing inflatable living modules, has raised a total of $2.2 billion. Creating "hotel-like living spaces" in space, a business that would have been a pipe dream a few years ago, is now a reality for investment.
The cost barrier has collapsed
Why are there so many unicorns now?
The biggest background factor is the dramatic drop in launch costs. What once cost tens of thousands of dollars just to transport 1kg of cargo into orbit has been compressed to under a few thousand dollars thanks to SpaceX's rocket reusability technology. Perhaps it is easy to understand if I call it the "arrival of low-cost carriers" for space. This change has fundamentally rewritten the profitability of the space business.
In 2025, the total number of successful orbital launches worldwide reached 321, setting a new record. As access to space increases, satellite operation costs also decrease, allowing various businesses to operate at realistic cost levels—the image is close to a state where "highways have been paved" in space.
Investment money is also active, and Crunchbase reports that the total amount raised by space startups in early March 2026 alone exceeded $2.4 billion. It is said that there is a possibility of setting a new record on an annual basis.
Omen of an IPO rush
Following the investment phase comes the wave of IPOs. Karman Space & Defense went public on the New York Stock Exchange in February 2025, with a valuation exceeding $11 billion. Analysts believe that if a SpaceX IPO becomes a reality, it will create a benchmark for the entire space sector in the stock market, triggering a positive chain reaction for the valuations and fundraising of other companies in the industry.
These developments are no longer irrelevant to industries that once thought they were far removed from space. Agricultural companies utilizing satellite data, shipping firms adopting space communications, and chemical manufacturers considering material experiments in space environments—more industries than one might imagine are beginning to have contact with space.
The total economic scale of the space industry is expected to reach approximately $626 billion as of 2025 and is projected to exceed $1 trillion by the early 2030s. The perception that "space is a world of romance" is gradually shifting toward "space is the next massive industry." We may well be looking up at a sky where unicorns have begun to fly in herds.
