Potential IPOs for OpenAI, Anthropic, and SpaceX could, by valuation, surpass all listings by U.S. tech giants over the past 45 years.

SpaceX’s market capitalization today already reaches $2 trillion.

By the end of the year, Anthropic with a $2 trillion valuation and OpenAI, valued at $1.2 trillion, could be added to the company.

If you add these figures together, the total valuation would be $5.2 trillion—more than the $4.1 trillion at which all Big Tech listings from 1980 to 2025 are valued.
