Can the Stock Market Swallow SpaceX, Anthropic, and OpenAI

If simultaneous IPOs by SpaceX, Anthropic, and OpenAI become a reality, they are expected to add up to $4tn to the market capitalization of US-listed companies.

Key IPO Scale and Timeline

• SpaceX: Aiming to raise $75bn and begin trading on Nasdaq on June 11.
• Anthropic & OpenAI: Reportedly each preparing IPOs of up to $60bn.

Market Impact and Risks

• Liquidity drain concerns: If index providers give these companies fast-track entry into benchmarks, there is a risk that the market's buying capacity could be immediately exhausted due to massive purchases by tracker funds.
• Potential for market correction: Since all three companies are key players in the AI industry, if their post-listing performance falls short of expectations, it could trigger a broader market correction.
• Reduced returns: Historical data shows that companies that go public at very high valuations relative to revenue tend to underperform the market average for years after listing.

Shifts in Capital Flows As tech giants begin using the stock market to reinvest in AI development instead of buybacks, there is a need to prepare for structural changes in capital markets and a 'capital diet' going forward.
