OpenRouter operates an API marketplace through which developers access and route requests across AI models from multiple providers. Its usage rankings are frequently cited in industry coverage as a signal of real-world model adoption; Meituan's LongCat-2.0, for example, served production traffic on the platform under the alias "Owl Alpha" before its open-source release and led the platform's usage rankings (Source: venturebeat.com).
The Information reported on July 17, 2026 that OpenRouter was in discussions about a potential sale to a larger technology company at a multiple of the $1.3 billion valuation set in its May 2026 CapitalG-led Series B. The platform spans more than 400 models, roughly 8 million users, and about 100 trillion tokens per month (Source: theinformation.com). On July 23, 2026 the Wall Street Journal reported that the prospective acquirer is Stripe, in talks to buy OpenRouter for roughly $10 billion; Stripe already handles OpenRouter's payments, and the deal would move it into the routing infrastructure that more than five million developers use to access hundreds of models (Source: finance.yahoo.com; pymnts.com). A report published July 29, 2026 stated that a purchase near $10 billion would value the three-year-old company at about 70 times its recent annualized revenue, according to a person with knowledge of its financials; the body of that report was not retrievable (Source: theinformation.com).
The talks became exclusive in August. A report of August 6, 2026 stated that Stripe had entered exclusive talks to buy OpenRouter in a cash-and-stock deal valuing the marketplace at close to $10 billion, and described the New York-based company as most recently valued at $1.3 billion. Only the publisher's abstract is retrievable, so no terms beyond the valuation and the cash-and-stock structure are established here, and the talks are exclusive rather than concluded (Source: theinformation.com).
Bloomberg reported on August 16, 2026 that Stripe had finalized an agreement to acquire OpenRouter for more than $7 billion, citing people familiar with the matter (Source: bloomberg.com). The reported price is below the roughly $10 billion figure carried in the July and early-August accounts, and no source reconciles the difference. As of August 17, 2026 neither company had confirmed the agreement, and a Stripe spokesperson said the company does not comment on rumors or speculation; the same report described OpenRouter's May 2026 raise as a $113 million Series B at a reported $1.3 billion valuation from investors including Sequoia, Andreessen Horowitz, Menlo Ventures and Alphabet's CapitalG (Source: techcrunch.com).
