Ramp Data: Anthropic Overtakes OpenAI in Enterprise AI Adoption

According to Ramp's latest AI Index report (published in August, based on July enterprise spending data), Anthropic has overtaken OpenAI in enterprise AI adoption and continues to widen the gap. In July, 43.5% of US businesses paid for Anthropic, up 1.1% month-over-month, while OpenAI's enterprise adoption stood at 39.7%. Meanwhile, overall US enterprise AI spending is showing signs of plateauing.

Confirmed

• Anthropic's July enterprise adoption reached 43.5%, versus 39.7% for OpenAI, with Anthropic up 1.1% month-over-month.
• Anthropic's growth is not driven by its latest flagship model, which accounts for only 6% of total token consumption.
• Overall US enterprise AI spending shows signs of peaking, even as market share among model vendors shifts structurally.

Why it matters

• The data marks a substantive shift in the enterprise AI competitive landscape, with Anthropic taking the lead in commercial deployment.
• Developers @kalomaze and @xeophon used the data to question the industry's common assumption that enterprises need frontier models to solve hard math problems. Drawing on his own experience solving an Erdős problem, @kalomaze argued that B2B SaaS software in real business scenarios has no need for frontier models to crack such problems, suggesting a mismatch between actual market demand for model capabilities and benchmark-centric evaluation standards.
