Anthropic PBC and OpenAI Inc Prepare for Public Listings

Anthropic PBC and OpenAI Inc. are preparing for public listings, with Anthropic targeting a debut by the end of 2026 and OpenAI's potential launch sliding into 2027. Anthropic recently overtook OpenAI in valuation after raising 65 billion dollars in May at a 965 billion dollar valuation and filing confidential paperwork on June 1.

Financial data shows a sharp divergence in growth trajectories. Anthropic's annualized revenue surged from 9 billion dollars at the end of 2025 to over 44 billion dollars by May. In contrast, OpenAI's valuation has remained relatively flat at 852 billion dollars since March, amid reports that the company missed internal revenue and user targets.

Market sentiment reflects this trend on Polymarket, where traders indicate a 67% probability that Anthropic will show greater valuation growth than OpenAI by the end of August. This includes a 65% chance of Anthropic reaching a 1.175 trillion dollar valuation, with bets settled using data from the Nasdaq Private Market.
