OpenAI has shifted its IPO timeline to 2027 after CEO Sam Altman described a 2026 listing as ill-advised amid rising focus on AI safety and alignment for its large language models. The company confidentially filed draft S-1 paperwork in June but is now accelerating a roughly $30 billion private funding round at a $1.25–1.4 trillion valuation to strengthen its balance sheet and fund infrastructure ahead of potential public market volatility. This move follows its $852 billion March valuation and comes as rival Anthropic prepares to list in mid-November, providing a direct test of AI lab investor appetite. Revenue growth toward $50–70 billion annualized supports the positioning, though substantial compute spending and regulatory scrutiny remain key variables for any 2027 resolution.
