The AI revenue race just flipped. Anthropic pulled ahead of OpenAI on quarterly revenue for the first time, posting $11.6 billion for the quarter ending in June against OpenAI’s $6.7 billion. The gap isn’t just about scale — Anthropic doubled its revenue quarter over quarter, while OpenAI managed an 18 percent bump. The Wall Street Journal reports that some OpenAI shareholders weren’t thrilled with the number, especially with an IPO supposedly on the horizon.
What’s driving Anthropic’s surge? Claude Code, its coding tool, has clearly resonated with developers in a way ChatGPT’s general-purpose interface hasn’t lately. Vercel’s data shows Anthropic earns significantly more per use from its Claude models than OpenAI does from ChatGPT. That per-use economics advantage matters more than raw user counts when you’re trying to build a sustainable business. OpenAI, meanwhile, saw its operating margin slide further into the red — a tough look for a company that’s been the category-defining name since late 2022.
The timing here is interesting. OpenAI claims growth picked up again after GPT-5.6 launched in July, which would land outside this reporting window. If that’s true, the next quarter could look very different. But the broader signal is hard to ignore: the assumption that OpenAI would run away with this market is looking shakier by the quarter. Anthropic’s sevenfold increase in annualized revenue rate — now at $65 billion — suggests enterprise and developer spending is flowing toward whichever model actually gets work done, not whichever chatbot has the most name recognition.
OpenAI still has the consumer mindshare and the distribution advantage. But Anthropic posting a small operating profit while OpenAI bleeds cash tells you something about where this market is heading. The company that wins the AI race won’t necessarily be the one with the most users — it’ll be the one that figures out how to make each interaction pay. Right now, that’s Anthropic.
