Woofun AI data shows that the National Venture Capital Association and PitchBook project combined valuations for SpaceX, Anthropic, and OpenAI to exceed $4 trillion. This figure surpasses the total exit value of all US venture capital-backed companies since 2000. SpaceX currently holds a $1.77 trillion valuation, significantly higher than Uber's $84 billion IPO in 2019. SEC data indicates last year's total US IPO fundraising was approximately $70 billion. The report attributes this trend to extended private periods and high capital intensity in AI model training.
