SpaceX, OpenAI, and Anthropic are preparing to go public within months of each other, potentially dumping nearly $3 trillion in highly valued tech stocks onto public investors who may end up as exit liquidity for early backers.
The numbers are staggering. SpaceX, OpenAI, and Anthropic are racing toward IPOs that could collectively demand $432 to $576 billion from public markets in a single quarter, according to analysis highlighted by BeInCrypto. To put that in perspective, the entire U.S. IPO market raised $469 billion over the past decade. We are watching an unprecedented stress test for public markets, and the timing could hardly be more consequential.
SpaceX filed its confidential registration with the SEC in early April 2026, targeting a $1.75 trillion valuation with a listing as soon as June. Internally codenamed "Project Apex," the offering involves 21 banks and aims to raise roughly $75 billion, which would be more than 2.5 times Saudi Aramco's 2019 record-setting raise. OpenAI follows with a target date in late 2026 or early 2027, seeking a valuation approaching $1 trillion. Anthropic, the smallest but perhaps the most financially disciplined of the three, is in discussions to list around the same time, with bankers expecting a raise exceeding $60 billion.
Here is what should make every retail investor pause. Early backers have already captured the lion's share of upside. Microsoft's roughly $13 billion investment in OpenAI is now estimated at $228 billion, an 18x return. Sound Ventures reportedly turned $20 to $30 million into $1.3 billion. These are extraordinary multiples, and they signal something important: the private money got in early and cheap. Public investors will be buying at all-time-high valuations, and several analysts have openly characterized these offerings as liquidity events where insiders cash out at the top.
OpenAI compounds the concern with its financials. The company is projected to lose roughly $14 billion in 2026 alone, with profitability not expected until 2029 or 2030 at the earliest. Its CFO, Sarah Friar, has reportedly expressed doubts internally about the company's readiness for a public listing, warning that revenue growth cannot sustain current spending plans, which include $600 billion in infrastructure over five years. Meanwhile, OpenAI's enterprise API market share has dropped from 50% in 2023 to 25% by mid-2025, a sharp erosion that suggests competitive pressure is already biting.
Why Anthropic May Have the Cleaner Pitch
Anthropic has its own challenges, including potential SEC scrutiny over how it reports cloud computing credits as revenue. But its growth story is harder to poke holes in. The company doubled annualized revenue from $9 billion to $19 billion in under four months. Roughly 80% comes from enterprise customers, a revenue mix Wall Street typically rewards with higher multiples than consumer-heavy business. Anthropic also projects positive free cash flow by 2027, three years ahead of OpenAI's breakeven target. Its enterprise API share climbed from 12% to 32% during the same period OpenAI's share was halved.
The sequencing battle matters because whoever lists first sets the tone. A strong debut could buoy the others. A disappointing one could suck the air out of the entire cycle. With three offerings of this magnitude hitting markets within months, the sheer supply pressure is uncharted territory. Institutional portfolios will need to make room, which means selling something else to buy in. Retail investors should be asking what they are actually buying: a stake in the future of artificial intelligence, or a ticket to someone else's exit.
Watch how the SpaceX listing performs in June. It will set the pricing expectations and appetite for everything that follows. If demand falls short of the hype, OpenAI and Anthropic may need to reconsider both their valuations and their timing. If it succeeds, brace for a scramble that reshapes tech sector weightings across every major index.
