OpenAI’s May 2026 confidential IPO filing preparations with Goldman Sachs and Morgan Stanley, targeting a potential September or fourth-quarter debut, represent the main catalyst behind current market-implied odds. The company’s latest private valuation reached $852 billion after a March 2026 round, supported by roughly $20 billion in 2025 revenue, yet persistent operating losses and heavy infrastructure spending create uncertainty about achieving a 2026 listing at $1.5 trillion or higher. Internal tensions, including reported clashes between CEO Sam Altman and CFO Sarah Friar over readiness and timeline, plus competition from Anthropic’s parallel IPO push, help explain why the “no IPO by December 31, 2026” outcome leads at 29.5 percent while the highest valuation bracket sits close behind. Plans remain fluid amid ongoing artificial intelligence development demands.
