Anthropic has reportedly reached a 65 billion dollar annualized revenue run rate, while OpenAI stands above 40 billion dollars.

Epoch AI has published new figures on revenue growth at the two leading AI labs. The combined annualized run rate of Anthropic and OpenAI rose from 30 billion dollars in January 2026 to 105 billion dollars by August 2026.

OpenAI tripled its annualized revenue run rate within a year, from 13 billion dollars in August 2025 to more than 40 billion dollars now. Anthropic grew from 1 billion to 9 billion dollars during 2025 and then accelerated further, more than tripling its run rate again in the first quarter of 2026 and reportedly reaching 65 billion dollars by the end of July 2026. Combined, the two labs already grew more than fourfold in 2025 and climbed from 30 billion to 105 billion dollars between January and August 2026.

For companies that buy or fund AI services, these figures provide a solid basis for pricing, capacity and investment decisions. Annual growth above 100 percent at companies of this size is considered extremely rare in the technology sector. The entire generative AI market is approaching 200 billion dollars in annual revenue, roughly one-thousandth of the global economy.

Epoch AI itself cautions against drawing quick conclusions: part of the surge traces back to coding assistants crossing a critical adoption threshold around the release of Opus 4.5, similar to the effect seen after the original launch of ChatGPT. It remains open whether further thresholds, such as automating broad office work, will follow, or whether growth will cool as in other maturing technology fields. At the current pace of tripling every year, the industry would mathematically reach the size of todays global economy within six years, a scenario the authors themselves call unrealistic.
