Anthropic reached a post-money valuation of $965 billion [1] after securing $65 billion [1] in a recent funding round.

This milestone marks a significant shift in the artificial intelligence landscape, as Anthropic now exceeds the market valuation of its primary competitor, OpenAI. The surge reflects intensifying investor confidence in the scalability of large language models and the commercial viability of AI safety-focused development.

The valuation was reflected on Forge Global, a secondary-market platform [4]. According to market data, OpenAI's valuation on the secondary market stands at approximately $880 billion [4].

Several high-profile investment firms led the funding effort. The round included Altimeter Capital, Dragoneer, Greenoaks, and Sequoia Capital [5]. These investors backed the company amid a period of rapid financial expansion and the broadening of cloud and compute partnerships [5].

Financial growth has been a primary driver for the valuation spike. Anthropic reported annualized revenue of $47 billion [3]. This revenue growth, combined with the massive capital injection, positions the company to aggressively expand its infrastructure and research capabilities.

The announcement occurred on Thursday, May 29, 2026 [2]. The influx of capital allows the startup to compete more directly with tech giants in the race for general artificial intelligence.

The shift in valuation leadership from OpenAI to Anthropic suggests that the market is placing a premium on Anthropic's specific approach to AI safety and its ability to scale revenue rapidly. By nearing a trillion-dollar valuation, Anthropic is no longer just a challenger startup but a systemic player in the global tech economy, signaling that the 'AI bubble' may be transitioning into a phase of massive, sustained corporate capitalization.
