Anthropic’s active push toward a November 2026 Nasdaq listing, backed by its confidential S-1 filing in June and surging revenue that recently exceeded a $100 billion annualized run rate, drives the market’s 96 percent implied probability that it will reach public markets before OpenAI. The company’s advisors have shifted the target from October to allow presentation of full third-quarter results during the roadshow, with expectations of a roughly $2 trillion valuation. In contrast, OpenAI CEO Sam Altman has stated that an IPO will not occur in 2026, citing the need to address artificial intelligence safety and alignment priorities as a private company, pushing any debut to 2027. While Anthropic’s timeline could still slip due to regulatory review or market conditions, OpenAI’s explicit deferral leaves few realistic paths for it to list first.
