Anthropic's confidential S-1 filing on June 1, 2026, followed by banker-led investor meetings targeting a potential listing as soon as October, has driven the 85.5% market-implied probability that it reaches public markets ahead of OpenAI. This timeline advantage stems from Anthropic's recent $65 billion funding round at a $965 billion valuation and active roadshow preparations, while OpenAI filed its own S-1 a week later but faces reports of leaning toward a 2027 debut amid internal readiness concerns. Trader consensus reflects these verified regulatory steps and competitive positioning in the large language model sector, though both remain subject to market conditions and potential delays typical in AI company IPOs.
