OpenAI’s latest funding round has anchored trader consensus around the $1.20–1.30 trillion range for its end-of-October 2026 valuation. Negotiations that began targeting $1.4 trillion settled at $1.25 trillion after investor pushback and a broader tech selloff driven by AI infrastructure spending concerns, with roughly $11 billion committed so far in a pared-back effort originally aimed at $30 billion. This marks a sharp increase from the $852 billion post-money valuation set in the March 2026 round, supported by reported annualized revenue reaching about $50 billion by late September and continued progress toward a 2027 IPO. While the round remains open and final terms could shift, the $1.25 trillion figure from credible funding documentation has produced overwhelming market-implied odds, though delays in closing or further market volatility could still introduce modest uncertainty.
