Stripe confirmed Wednesday its acquisition of OpenRouter, an AI startup that routes prompts between different language models, paying $7.5 billion according to sources familiar with the deal.
The valuation represents a 480 percent jump from OpenRouter's $1.3 billion valuation in May. Stripe outbid Databricks and other suitors, the sources said.
OpenRouter's founders will receive $1.5 billion; investors split the remaining $6 billion.
Stripe founders Patrick and John Collison framed the deal as part of capturing AI's economic expansion. The company has seen new firm creation surge as AI adoption spreads—88 percent of Forbes AI 50 companies use Stripe, including OpenAI and Anthropic. All of Brex's fastest-growing startups are Stripe customers.
OpenRouter helps developers manage costs across multiple AI models. The synergy is direct: developers are Stripe's core constituency, and AI model expenses are a growing line item for Stripe's customers.
Internally, Stripe plans to integrate OpenRouter's technology to build model-agnostic AI agents within its own platform. OpenRouter will operate independently post-close, expected in weeks, with its product and commitments unchanged.
The deal marks a strategic shift. Stripe's earlier large acquisitions focused on cash inflows—collections, invoicing, capital solutions. The OpenRouter acquisition signals a move to the expense side, starting with AI spend. As AI model costs grow, Stripe is positioning itself to own both the inbound and outbound money flows for its developer customer base.
