Altman is Anxious: OpenAI's Three-Year Reign Has Just Been Overtaken by Anthropic
In May 2026, Anthropic has historically overtaken OpenAI in workplace adoption, according to Ramp's AI Index based on real business spending data. Anthropic's enterprise adoption rate reached 34.4%, surpassing OpenAI's 32.3%. Over the past year, Anthropic's rate grew nearly fourfold, while OpenAI's grew only 0.3%. Key to Anthropic's surge is its shift to a usage-based, per-token billing model and the integration of AI Agents into core business workflows, driving massive token consumption and revenue growth—reportedly reaching an annualized ~$44 billion. Despite concerns over rising costs and service stability, enterprises exhibit heavy reliance on Claude for productivity gains. OpenAI has responded with defensive measures, including offering free enterprise trials. The competition has shifted from model benchmarks to deep workflow integration, marking a new phase in the enterprise AI battle.
