OpenAI CEO Sam Altman stated in September 2026 that an IPO this year would be ill-advised due to AI safety priorities, with CFO Sarah Friar confirming internally that the company plans to go public in 2027. This aligns with ongoing talks for a $30 billion private bridge round targeting a $1.4 trillion valuation after the March 2026 raise at $852 billion, allowing more runway amid heavy compute spending and projected losses. The market-implied odds of 97.4% against a $1 trillion-plus listing before 2027 reflect trader consensus on these explicit timelines and the preference for private capital over rushed public scrutiny. While strong revenue growth nearing $70 billion annualized supports the valuation push, factors like regulatory shifts on AI governance or abrupt market sentiment changes remain low-probability disruptors.
