Stripe acquires OpenRouter for $7B+ to unify AI model access

Stripe has reportedly agreed to acquire OpenRouter for more than $7 billion, according to Bloomberg, turning the payments giant into a major player in AI infrastructure. OpenRouter acts as a unified gateway that lets customers choose among hundreds of AI models—from OpenAI, Anthropic, Google, and others—based on task requirements, latency, and budget. The startup, founded by CEO Alex Atallah, raised a $113 million Series B in May at a $1.3 billion valuation, with backing from Sequoia, Andreessen Horowitz, Menlo Ventures, and Alphabet's Capital G. At the time, Atallah described OpenRouter as "Stripe for AI," providing a single access point to prevent vendor lock-in. The company claims 8 million global users and access to more than 400 models.

The deal follows The Wall Street Journal's February report that the two companies were in acquisition talks. While a Stripe spokesperson declined to comment, the reported $7 billion price tag represents a massive premium over OpenRouter's last valuation—roughly 5.4x. For Stripe, the acquisition aligns with its push into AI-related payments and infrastructure, allowing businesses to manage model calls, billing, and usage through Stripe's existing suite. For OpenRouter users, the deal could mean deeper integration with Stripe's enterprise payment rails, potentially simplifying metering and invoicing for AI workloads. Analysts see this as a strategic move to own the middleware layer between AI models and developers, positioning Stripe as the default financial and routing layer for the AI economy.
