SpaceX's completed June 2026 IPO, priced at roughly $1.75–1.8 trillion with a record $75–85 billion raise and an initial surge above $2 trillion, underpins trader consensus favoring its closing market cap over OpenAI's expected debut. SpaceX's established revenue trajectory from Starlink and launch services, combined with its public trading history showing resilience despite post-IPO volatility, provides a clear benchmark that OpenAI has yet to match. OpenAI remains private at an $852 billion March 2026 valuation after a major funding round and has delayed its IPO into 2027 to pursue a $1 trillion-plus target, citing caution from SpaceX's swings and infrastructure spending needs. Key catalysts include OpenAI's confidential SEC filing in June and ongoing large language model scaling efforts, but the timing gap and lower private mark currently tilt sentiment toward SpaceX's realized valuation edge in this comparison of skin-in-the-game trader odds.
