Anthropic’s aggressive IPO preparations, including a confidential S-1 filing in June 2026 and an active push toward a November 2026 Nasdaq listing at a potential $2 trillion valuation, underpin the 94.8% market-implied odds that it will reach public markets ahead of OpenAI. The company’s annualized revenue run rate has surged past $100 billion amid strong Claude adoption, with underwriters advancing roadshow planning and credit facilities. In contrast, OpenAI CEO Sam Altman stated in September 2026 that a 2026 listing would be “ill-advised” amid heightened AI safety priorities, shifting any debut to 2027. Trader consensus reflects these timelines, though Anthropic could still face slippage from regulatory reviews or market volatility, while OpenAI might accelerate if safety concerns ease faster than expected.
