Prediction‑market traders on platforms like Kalshi and Polymarket see a wave of mega‑IPOs from SpaceX, OpenAI and Anthropic that could dwarf even Berkshire Hathaway’s market cap. SpaceX has filed to go public on Nasdaq and is valued at about $1.25 trillion; traders give it a 56 % chance of closing its debut above $2.2 trillion. OpenAI, recently valued at $852 billion, is expected to file for an IPO in 2026 with a 92 % probability, and a 65 % chance of starting trading above $1.4 trillion. Anthropic, valued near $900 billion, carries a 69 % likelihood of an IPO this year and a 47 % chance of a debut above $1.8 trillion. If realized, each would join the “$1‑trillion club” and surpass the market caps of Berkshire Hathaway, Meta and Tesla, even though SpaceX and OpenAI remain unprofitable. Analysts note that while the U.S. market—about $70 trillion in total—could absorb such offerings, the rapid succession of high‑valued IPOs raises questions about sustained demand.
