Stripe Acquires AI Gateway Startup OpenRouter in Reported $7.5 Billion Deal
Payments giant Stripe has confirmed its acquisition of OpenRouter, a startup that routes prompts between various artificial intelligence models. While Stripe did not publicly disclose the financial terms of the transaction, sources told the New York Times that the acquisition price reached $7.5 billion.
The reported purchase price represents a significant increase from OpenRouter’s valuation of $1.3 billion in May. Under the reported terms of the transaction, the startup’s founders will receive $1.5 billion from the sale, while investors are set to receive the remaining $6 billion. Stripe reportedly outbid several other parties interested in acquiring the fast-growing startup, including data analytics platform Databricks.
The Strategic Shift to AI Expense Management
Historically, Stripe’s major acquisitions have focused on helping businesses collect and manage incoming revenue. The acquisition of OpenRouter signals a strategic expansion into expense management, specifically targeting the growing field of AI and token expense management.
According to Franco Granda, a research analyst at PitchBook, this acquisition represents a deliberate effort by Stripe to position itself at the center of capital flows within the AI sector. Granda noted that OpenRouter will provide Stripe with insight into how developers utilize AI, while also granting the company "some degree of power over suppliers such as the frontier labs themselves, as well as hyperscalers and neoclouds."
Stripe is not alone in targeting this emerging market. Several other companies have recently entered the token expense management space. Databricks has developed its own AI gateway, while financial technology firms Rippling and Ramp have both launched gateways focused on managing employee AI spend and return on investment.
Developer Overlap and Future Operations
In a leaked letter to investors verified by TechCrunch, Stripe founders Patrick and John Collison highlighted the overlap between the two companies' customer bases, noting that OpenRouter is highly useful for developers and that Stripe operates one of the world's largest developer platforms.
The founders also made a tongue-in-cheek reference to "the singularity" in their letter, writing that they decided January 1 marked its beginning and have been operating on that basis. Patrick Collison previously used the term in a humorous context during the company’s conference in April.
On the business front, Stripe has experienced an economic uptick driven by the growth of the AI sector. The company reports that 88% of the Forbes AI 50, including major players like OpenAI and Anthropic, use its payment products. Additionally, Stripe services are used by 100% of Brex’s fastest-growing startups.
OpenRouter is expected to continue operating independently once the transaction closes in a few weeks. In a blog post, the startup stated that its product, mission, and current commitments will remain unchanged following the acquisition.
