Enterprise AI spending has shifted decisively toward Anthropic, which now accounts for the majority of API spending while OpenAI trails, according to Vercel AI Gateway data.

Ramp data through 2026 shows Anthropic capturing a substantial share of business AI spending, with Vercel data placing Anthropic above 60% of enterprise spend by mid-year.

A typical enterprise setup features a multi-provider environment, with about two-thirds of development teams routing complex tasks to Claude while cheaper providers handle routine work.

Analysts point to evolving enterprise AI spending dynamics, underscoring pricing, product strategy, and multi-provider workflows as key levers of market leadership.

OpenAI still shows growth in certain business cohorts in Q3 2026, signaling that enterprise competition remains unsettled with pockets of OpenAI strength.

Anthropic’s revenue mix is roughly 80% enterprise/API, emphasizing Claude-driven business integrations, whereas OpenAI leans more on consumer products and broader ecosystems for distribution.

In coding and agentic applications, Anthropic commands about 54% of the enterprise market, with OpenAI around 21%.

From 2023 to 2025, Anthropic rose from roughly 12-40% of enterprise LLM spend while OpenAI declined from about 50% to 27%, a trend continuing into 2026.

Average spend per user is higher with Anthropic, at about $420 versus roughly $310 for OpenAI.

Anthropic’s pricing is strong, charging roughly 4.4 times the average price per token compared with OpenAI, and capturing 61-65% of spending on only 30-32% of total token volume.
