Stripe has completed the acquisition of OpenRouter for over $7 billion, according to the latest report from Bloomberg. This is considered one of the largest AI M&A deals to date, although Stripe maintains its stance of “not commenting on rumors and speculation.”
OpenRouter operates as an “AI gateway,” helping customers select different AI models for specific tasks based on their needs and budget. Its core value lies in a single access point: instead of being locked into a single provider, users can flexibly switch between hundreds of models.
The startup’s scale is by no means small. In May, OpenRouter announced that it had raised $113 million in a Series B round at a $1.3 billion valuation, with participation from Sequoia, Andreessen Horowitz, Menlo Ventures, and Alphabet’s CapitalG. The company claims to have 8 million global users and provide access to more than 400 different AI models.
An interesting detail lies in how CEO Alex Atallah describes his company: the “Stripe for AI.” This comparison is not merely a marketing gimmick—it reflects OpenRouter’s ambition to become the equivalent infrastructure for the AI model interface layer, just as Stripe once simplified online payments for businesses everywhere.
The $7 billion valuation, more than five times its Series B valuation just a few months ago, highlights the rapid growth and market expectations for the AI gateway sector. The Wall Street Journal reported last month that the two parties were in negotiations, and now Bloomberg confirms that the discussions have resulted in a deal valued at over $7 billion.
For Stripe, the transaction follows a clear logic: payment infrastructure is advancing deeper into the AI application layer. As AI products increasingly require usage-based billing, a payments company with a built-in gateway to diverse models holds a major structural advantage. The only remaining questions are when Stripe will officially confirm the deal, and how it will integrate OpenRouter’s 8 million users into its ecosystem.
