Stripe confirmed it has finalized an agreement to acquire OpenRouter for over $7 billion, expanding into the AI sector with the deal closing in August 2026 [1, 2]. OpenRouter, founded in 2023 and based in New York, offers developers access to more than 400 AI models aimed at efficient, affordable solutions for software development [1, 2].
The acquisition value exceeds OpenRouter's previous valuation of $1.3 billion and follows capital raises totaling over $150 million to date. The startup has attracted prominent Silicon Valley investors including CapitalG, Andreessen Horowitz, and Menlo Ventures [1, 2].
As of May 2026, OpenRouter serves roughly 8 million developers worldwide, providing seamless access to hundreds of AI models via its platform [2]. This positions Stripe beyond its payments processing roots toward AI-driven services.
OpenRouter’s former CEO Alex Atallah, who previously co-founded the OpenSea NFT marketplace, led the company until stepping down in July 2026, shortly before the acquisition closed [2]. Details of the acquisition remain confidential, and the final price could still change. A Stripe spokesperson declined to comment on rumors or speculation surrounding the deal’s specifics [1].
The acquisition marks a major investment by Stripe in the fast-growing AI field. The transaction closed weeks after Atallah’s departure, potentially signaling a leadership transition during the integration phase [2]. Further updates on OpenRouter’s integration into Stripe are expected in the coming months.
