Polymarket traders expect OpenAI, Anthropic, and SpaceX to trade at valuations exceeding $1.4 trillion on their first day of public trading. SpaceX has officially filed for its IPO, while reports suggest OpenAI is preparing for a confidential filing. These speculative market bets indicate that these tech giants could immediately become some of the world's most valuable companies upon listing.

This momentum arrives as Berkshire Hathaway (BRK.B) holds a market capitalization of approximately $880 billion per market data, placing the combined projected value of the three firms well above Warren Buffett's conglomerate. For context, the surge in AI demand mirrors the trajectory of Nvidia, which recently surpassed the $2 trillion valuation mark (per Bloomberg reports), fueling aggressive pricing for upcoming tech unicorns.

Investors should monitor official filing updates alongside upcoming macro catalysts, including speeches by Fed officials Williams and Barr on May 14, 2026, which may impact IPO risk appetite. Additionally, U.S. Industrial Production data due May 15, 2026, will be a key indicator for capital flows into high-growth sectors as these companies approach their market debuts.
