SpaceX, OpenAI and Anthropic IPOs Could Mint $4 Trillion, Pressuring Microsoft
3 articles · Updated · Computerworld · Jun 24
Summary
$4 trillion in combined value could be created within months if SpaceX lists above $2 trillion and OpenAI and Anthropic each reach $1 trillion, adding three new public AI rivals to Microsoft.
Microsoft enters that wave weakened: its stock has fallen 24% over 12 months while the S&P 500 rose 24%, and Google’s market value has climbed to $4.5 trillion from $2.1 trillion a year earlier.
New AI listings could divert investor money from Microsoft and make stock-funded deals harder, even though Microsoft’s 27% OpenAI stake would be worth about $270 billion at a $1 trillion valuation.
Azure stands to benefit because OpenAI is committed to buy $250 billion in services through 2030, while HSBC estimates Anthropic could spend $43 billion a year on Azure by 2030.
Copilot remains the bigger vulnerability: Microsoft 365 Copilot has 20 million paid seats out of 450 million commercial subscribers, and GitHub Copilot is losing developer share to Claude Code and Cursor.
Is Microsoft's AI strategy now just profiting from its competitors through Azure and its OpenAI stake?

Overview
In 2026, the IPO market is experiencing an unprecedented surge, driven by record valuations for companies like Anthropic, OpenAI, and SpaceX. This historic wave marks a major shift in capital markets, with investor enthusiasm reaching levels not seen since the railroad mania of the 19th century. However, concerns are rising about the sustainability of this boom, as the amount of money flowing into AI now exceeds past speculative periods. Anthropic leads the charge, having confidentially filed its S-1 after closing a major funding round, highlighting both the excitement and the risks of this new era.
