OpenAI CEO Sam Altman ruled out a 2026 IPO in September, citing AI safety priorities and the need to address alignment risks before a public listing, shifting expectations toward 2027 at the earliest. This has driven Polymarket odds heavily toward no IPO by December 31, 2026. The company’s March 2026 round closed at an $852 billion post-money valuation, while current talks center on a $30 billion bridge financing at roughly $1.4 trillion pre-money, supported by annualized revenue reaching about $50 billion in September and projections exceeding $70 billion by year-end amid 77% third-quarter run-rate growth and faster enterprise expansion. A confidential SEC filing from June remains non-public, with no pricing or date set. Traders weigh these private valuation signals and revenue momentum against the delayed timeline when assessing potential closing market-cap thresholds if an IPO occurs sooner than anticipated.
