OpenAI Revenue Chief Accuses Anthropic of Inflating Revenue by $8 Billion

OpenAI and Anthropic are competing for generative AI enterprise customers and cloud computing capacity. OpenAI Chief Revenue Officer Denise Dresser argues that Anthropic’s growth narrative rests on particular accounting methods and reliance on a single product. Her allegations also underscore intensifying competition between the companies for customers, funding and market valuations.

As of July 19, 2026, a leaked internal OpenAI memo showed Dresser accusing Anthropic of overstating its annualized revenue by about $8 billion and criticizing its computing capacity and product strategy. The memo also revealed that OpenAI plans to broaden its sales channels through Amazon and build a DeployCo deployment engine to accelerate enterprise adoption and market expansion.
