SpaceX and OpenAI set stage for historic 2026 IPO showdown

Wall Street is bracing for the summer and year of 2026 that will reshape the capital markets. After years of dormancy, initial public offerings began gaining momentum in 2025 as interest rates fell. But two titans—with a possible third in the wings—have hit the accelerator, and their rivalry will produce back-to-back offerings that dwarf anything the markets have seen before.

SpaceX filed its IPO prospectus yesterday with the full architecture of what will be the largest debut in stock market history. The aerospace company begins trading on June 12. It aims to raise between $75 billion and $80 billion, with a valuation between $1.8 trillion and $2 trillion—the highest figures ever attached to a newly public company. But the real story is not SpaceX alone. The company faces an old adversary in the courts: Sam Altman. His firm, OpenAI, plans to launch its own public offering in September, according to multiple reports. Once the courts rejected Elon Musk's attempt to seize control of ChatGPT's creator, the company began filing the necessary documents to publish its prospectus over the summer. The legal battle between them was the only thing preventing the move. Now, with that obstacle cleared, it is simply a matter of months. The Wall Street Journal confirms the September timeline and reports that Goldman Sachs and Morgan Stanley are already working on the offering documents.

The combined effect will be the centerpiece of a stellar year. Goldman Sachs calculates that 2026 will see at least $160 billion in capital raised through IPOs. A third unexpected guest, Anthropic, is preparing its own public debut for late in the year, aiming to raise $60 billion on its own. Beyond these three sit other notable offerings from Canva, Shein, and Stripe. The reason for this historic wave is a mix of lower interest rates compared to 2025 and somewhat more stable macroeconomic conditions. S&P Global notes that these relaxed financial conditions follow years of "restraint" where companies have waited for their moment. In 2019 and 2020, Wall Street IPOs raised roughly $46 billion. Then came a boom of $142 billion in 2022, followed by a desert of just $7.7 billion in 2023 and $19.4 billion in 2024. By 2025, the market had normalized to $44 billion. SpaceX's offering alone will exceed the total IPO volume of last year.

Yet the two companies operate in fundamentally different ways. OpenAI is the standard-bearer of generative artificial intelligence, while SpaceX has traveled a different path entirely. Though often dismissed as the passion project of a South African entrepreneur, SpaceX has quietly achieved undisputed leadership in another revolution: satellites. The cost of launching a satellite into orbit has dropped dramatically because rocket boosters can now be reused. This has made a "space wars" economy viable, and the data these satellites provide will become the backbone of a trillion-dollar business. The World Economic Forum expects the sector to reach $1.8 trillion by 2035. Satellite data will be critical for communications infrastructure, military applications, ship navigation, and countless other industries. McKinsey recently noted that "in a connected world, the space industry will be a connecting element for all industries on the planet." Licenses to launch satellites have become extraordinarily valuable assets—SpaceX paid $18 billion just for EchoStar licenses. The market is growing at 20 percent annually, and SpaceX dominates it absolutely.

But the numbers tell a more complicated story. SpaceX operates a strong, established business in spacecraft and in Starlink, its internet satellite constellation, which generated $4.42 billion in profit in 2025. Yet its AI division—the former xAI, merged with the rocket company months ago—lost $6.36 billion that same year. Worse, the losses are accelerating: the division bled $2.47 billion in the final quarter alone, erasing all company profits. In practice, SpaceX is a viable, successful space business that subsidizes an AI operation with no near-term path to profitability. Musk merged them because he needs a steady revenue stream to finance AI's enormous capital demands. He envisions data centers in space, powered by solar energy and cooled by the vacuum, to slash costs and "unlock trillion-dollar markets on the Moon, Mars, and beyond."

OpenAI, by contrast, is betting everything on a single card: artificial intelligence. The company that launched the AI revolution with ChatGPT is focused entirely on this sector. The good news for investors is that they do not have to worry about a mixed portfolio with divergent futures. The problem is that nothing covers the losses this segment generates. OpenAI's 2025 revenue reached $20 billion, up from $6 billion in 2024, but the company reported no profit. It is in expansion mode, reinvesting everything into chips, data centers, and talent to maintain its position. More troubling, the Wall Street Journal reports that OpenAI has planned losses of $85 billion for the three-year period from 2026 to 2028, with red ink mounting each year. In 2025 alone, the company lost $9 billion. HSBC calculated in November that the company needs $207 billion in financing through 2030, with no immediate expectation of profitability. On April 28, CNBC reported that OpenAI had fallen short of its revenue and user targets. The IPO is a way to tap retail investors—a funding source previously unavailable. The risk of betting everything on one outcome is that the company may not take off in time.

Both firms conducted recent funding rounds that offer a window into how public markets may value them. On March 31, OpenAI raised $122 billion in a historic round, valuing the company at $852 billion. Investors included Amazon, Nvidia, and SoftBank. Yet this was merely a prelude to a public offering where all investors can participate and valuations are expected to soar much higher. SpaceX's last funding round was in December 2024, valuing the company at roughly $800 billion. In March 2026, a private share sale valued it at $1.2 trillion. But a dark horse is emerging. Anthropic, led by Dario Amodei, has revealed financial results that suggest it has cracked the code. The company behind Claude reported $4.8 billion in first-quarter revenue, growing faster than Google or Facebook did before their IPOs. Anthropic projects $10.9 billion in the second quarter and expects its first operating profit—$559 million—in the third quarter. Last week, in a funding round, Anthropic raised $30 billion and was valued at $900 billion, according to the Financial Times, though the deal has not been officially disclosed. This represents a massive jump from its previous round, Series G, where it raised $30 billion at a $380 billion valuation. Anthropic has already surpassed OpenAI in user numbers, devouring ChatGPT's initial advantage. For SpaceX, the rocket and Starlink businesses provide a crucial hedge. But the AI war may soon become a three-way battle in which only one company can claim genuine profitability.
