OpenAI is discussing a new funding round that would value the company at as much as $1.5 trillion, more than double its prior $730 billion valuation, according to reports first from the New York Times and confirmed by the Wall Street Journal and Forbes on September 16, 2026. The push for a higher valuation than the $1.2 trillion investors had offered comes days after CEO Sam Altman said OpenAI will not attempt an IPO in 2026, and is attributed to accelerating customer growth for its Codex coding tool and newest models. If completed, the round would make OpenAI the world’s most valuable private company.
