The “liquidity drain” panic
Three giant names — Anthropic, SpaceX, and OpenAI — are hovering around the IPO runway, and that’s enough to make Wall Street clutch its pearls. The headline number sounds dramatic: a combined $4 trillion to $5 trillion in value. Cue the panic that all this shiny new stock will vacuum money out of the rest of the market.
But that’s a little like seeing a concert poster and assuming the whole stadium is being sold. Market cap is the size of the pie; what actually gets sold to the public is only a slice. In this case, the actual cash raised is expected to be closer to $200 billion across all three deals — and even that may be generous if the free float stays tiny.
Small float, big hype
That’s the twist here: these companies could have gigantic valuations while still leaving most of the shares locked up with founders, insiders, and early backers. According to the article, SpaceX may float only about 4.3% of its shares, which means public investors won’t be flooded with stock the way they would be in a giant commodity offering.
And if you’re wondering whether Amazon matters in this story: only as a side character. It has already poured roughly $8 billion into Anthropic and pledged up to $25 billion more, while also committing up to $50 billion to OpenAI. So yes, Amazon has skin in the AI game — but this story is really about the market’s appetite for mega-cap AI dreams, not AMZN’s own stock.
The bigger question is pricing
The stronger argument isn’t that these IPOs will drain liquidity. It’s that they could stretch valuations even further while the companies are still losing money. Yardeni’s math says the three together lost more than $25 billion in 2025, which means investors are being asked to buy a very expensive promise.
Big picture: the market may not run out of cash. But it could run into the usual problem — paying too much for the future and hoping the future shows up on time.
