Anthropic Overtakes OpenAI in Revenue as ChatGPT Falls Below 50% Market Share
Summary: Anthropic has surpassed OpenAI in annualized revenue while ChatGPT's web-visit market share dipped below 50% for the first time — a historic competitive shift just months before OpenAI's planned IPO.
Key Facts
- Anthropic on track for $47B annual run rate (as of May 2026), projecting profitability by 2029
- OpenAI's ARR estimated at $25–33B, with breakeven targeted for 2030
- ChatGPT's share of worldwide generative AI web visits fell below 50% in May, with Gemini and Claude gaining ground
- Sam Altman proposed a US-led international AI safety forum in a Financial Times op-ed, signaling a strategic pivot toward global governance positioning
Why It Matters
This is the first time a competitor has materially outpaced OpenAI in revenue since ChatGPT launched the generative AI era. The White House's restriction on GPT-5.6 rollout — combined with Anthropic's release of Claude Sonnet 5 — accelerated the shift in enterprise and developer preference. With its IPO in the pipeline, OpenAI now faces heightened investor scrutiny over whether it can regain the revenue lead.
