Stripe is acquiring OpenRouter, an AI gateway startup, in a deal valued at over $7 billion, according to reports. The acquisition marks Stripe's largest purchase to date and reflects the payments giant's aggressive push into AI infrastructure.
OpenRouter functions as a unified interface for accessing multiple large language models. The platform lets developers build applications that can switch between different AI models, manage costs, and handle routing logic without rebuilding infrastructure for each model provider. OpenRouter CEO Anmol Bhardwaj has described the startup as "Stripe for AI," positioning it as critical plumbing in the emerging AI stack.
The deal price exceeds Stripe's previous largest acquisition, its 2020 purchase of Hop for over $100 million. At $7 billion-plus, this values OpenRouter as one of the highest-valued AI infrastructure plays in the market, comparable to companies like Mistral AI and Anthropic.
Stripe's move signals a strategic bet that AI gateway infrastructure will become as essential to developers as payment processing. The company gains OpenRouter's technology and customer relationships while positioning itself at the center of AI model consumption. Stripe already processes trillions in payment volume annually. Adding AI routing capabilities creates new revenue opportunities through API calls and model access transactions.
OpenRouter has raised funding from backers including prominent venture firms and angel investors who recognized the startup's role in standardizing how developers access AI models. The platform abstracts away vendor lock-in, allowing developers to experiment with different models and compare performance without architectural changes.
For Stripe, the acquisition extends its infrastructure playbook beyond payments. The company has spent years building developer-friendly APIs and billing systems. OpenRouter's gateway layer fits naturally into Stripe's broader ambitions to become the operating system for internet commerce. By owning the AI routing layer, Stripe can offer bundled services combining payments, billing, and AI model
