Price War: OpenAI Wins Back Business Customers From Anthropic

The A.I. price war is having an effect, and it is favoring OpenAI: Among companies that buy A.I. models through the OpenRouter platform, OpenAI has all but closed its gap with Anthropic within a year. According to a report by The Wall Street Journal, the two rivals split spending almost evenly in September among roughly 120,000 companies that use products from both. At the start of the year, Anthropic accounted for about three-quarters of it. OpenRouter routes requests for A.I. models to different providers based on price and performance, and Stripe bought the platform this summer for $7.5 billion. Its data therefore shows fairly directly where companies actually spend their money.
