OpenAI just completed a $7 billion buyback of employee shares at an $852 billion valuation—the same valuation it held back in March. The move comes as Anthropic has been adding roughly $100 billion to its valuation month over month, and as both companies race to prove their models can solve problems that have stumped mathematicians for over a century.

The $7 billion tender offer is one of the largest employee buybacks a private company has ever done. OpenAI has a pattern of regular secondary sales, letting employees sell shares for the last three years. But the flat valuation since March raises questions.
