OpenAI CEO Sam Altman’s September 12 confirmation that an IPO this year would be “ill-advised” amid elevated AI safety and alignment priorities has anchored trader consensus at 96.5% against any listing by December 31, 2026. The June confidential S-1 filing and earlier banker discussions of a potential Q4 2026 window at up to $1 trillion valuation have given way to internal focus on a possible 2027 debut or an interim private round targeting $1.2–1.5 trillion, following the March $852 billion post-money round. Recent revenue growth past $40 billion annualized and ongoing safety-related regulatory scrutiny reinforce the preference for remaining private, while any acceleration in model performance or resolution of governance issues could still reopen a narrow path to an earlier listing.
