OpenAI reported a revenue inflection in the third quarter of 2026, with enterprise sales overtaking consumer sales as its biggest revenue driver. The recovery came after a difficult first half in which Anthropic gained ground in enterprise AI spending.
Why it matters
The shift signals intensifying competition between OpenAI and Anthropic for business customers, a market increasingly central to the AI industry's finances. OpenAI's ability to rebound ahead of a planned public listing bears directly on investor confidence in the sector.
A September OpenRouter analysis of about 120,000 companies found OpenAI and Anthropic with roughly even enterprise spending shares, down from Anthropic's three-quarters share at the start of the year. Exact third-quarter revenue figures for OpenAI were not disclosed in the source material.

Big Picture
The shift follows OpenRouter's September analysis of about 120,000 companies, which showed OpenAI and Anthropic with roughly even enterprise spending shares after Anthropic had held about three-quarters at the start of the year. OpenAI's third-quarter enterprise gains extend that competitive race into a new phase.
Businesses weighing AI vendors may see the enterprise competition between OpenAI and Anthropic shape pricing and product options. The rivalry also affects which tools and agent features become available to workplace software users.
The takeaway
Enterprise adoption is becoming the decisive battleground for AI companies, and rapid shifts in customer share can reverse a company's fortunes within months. Watch enterprise spending trackers to gauge which AI vendors are winning business customers.
What happens next
OpenAI plans to go public in 2027, and the company is seeking to raise $20 billion after raising less than half of its targeted $30 billion in its latest round.
