OpenAI’s trader consensus around a $1.00–1.20 trillion valuation at end-October 2026 reflects the March 2026 $122 billion round that set an $852 billion post-money mark, followed by secondary trading prints near $1.16 trillion and early talks of a $30 billion-plus pre-IPO bridge at roughly $1.4 trillion. Recent revenue data showing a $50 billion annualized run rate in September—below some prior projections yet still targeting $70 billion by year-end—along with the September DevDay launches of GPT-6.1 Sol, Dots agents, and higher-tier subscriptions have sustained momentum without triggering a new closed round. Altman’s comments on AI safety and the shift of any IPO to 2027 have kept focus on private-market sentiment and secondary liquidity as the key near-term valuation drivers.
