Anthropic's Quarterly Revenue Surges to More than $11.5 Billion

Anthropic's preliminary second-quarter revenue surged to more than $11.5 billion, representing more than a 14-fold increase from the same period a year earlier, according to documents reviewed by Bloomberg News.

The Claude chatbot maker reported preliminary revenue of more than $11.5 billion in the latest quarter, compared with $787 million in the second quarter of 2025 and $4.73 billion in the first quarter of 2026.

The company also reported positive adjusted operating income for the quarter.

The rapid growth comes as Anthropic competes with OpenAI for corporate customers. The company has benefited from increased adoption of Claude for professional tasks, particularly software development.

Anthropic's annualized revenue run rate had crossed $47 billion in May, according to Bloomberg.

More recent reporting indicates that the company's annualized revenue run rate has since risen to roughly $65 billion, putting it ahead of OpenAI's reported run rate of about $40 billion. 

Because companies can calculate annualized revenue and run-rate figures differently, comparisons between Anthropic and OpenAI should be treated cautiously.
