OpenAI Tops Anthropic in Enterprise AI Spending as Rivalry Intensifies

OpenAI has regained an edge over Anthropic in one measure of enterprise AI demand, with Ramp data cited by Business Insider showing OpenAI’s GPT models generated about 1.33 times as much business spending as Anthropic’s top model in July 2026. The figures suggest that while Anthropic still leads in overall business adoption across Ramp’s customer base, OpenAI’s most advanced offerings are attracting relatively stronger spending from companies. The report highlights how closely the two AI rivals are competing for enterprise customers, a market that has become a key test of commercial momentum in the AI boom.
