Anthropic has pulled ahead of OpenAI on annual revenue, and the gap may widen before either company reaches the public market. According to The Information, the Claude maker is now generating at least 35% more on an annualized basis, a sharp reversal from the first quarter of 2026, when OpenAI was still ahead by nearly $1 billion.
That kind of swing is unusual even in AI, where numbers move fast and investors have been trained to tolerate chaos with a spreadsheet. It also suggests the race is no longer just about model quality or brand heat; revenue growth, enterprise traction, and user momentum are starting to matter just as much.
Anthropic’s revenue lead over OpenAI
The new figures point to a company that is scaling quickly while its bigger rival hits a softer patch. The Information says Anthropic’s growth remains strong, while OpenAI is seeing slower new-user inflows, a combination that could extend the current lead by the end of the year.
For a startup preparing for an IPO, that matters. Public-market investors tend to reward growth that looks durable, and they punish stories that depend too heavily on hype. If Anthropic can keep this pace, it may walk into the market with a cleaner narrative than OpenAI, even if OpenAI still has the louder name.
What the shift could mean for IPO pricing
IPO timing is doing a lot of work here. Both companies are expected to head toward public listings, and whichever one arrives with stronger revenue metrics could set the tone for valuation talk across the AI sector.
- Anthropic is now described as generating at least 35% more annualized revenue than OpenAI.
- OpenAI was still ahead by nearly $1 billion in the first quarter of 2026.
- The key risk for OpenAI is slower user growth, not lack of attention.
- The key opportunity for Anthropic is turning enterprise demand into a valuation premium.
If these numbers hold, the next question is whether OpenAI responds with faster product shipping, a tighter go-to-market push, or simply a better story for investors. In a market this crowded, revenue leadership can flip quickly – and so can the mood on Wall Street.
