Stripe plans to acquire OpenRouter, a startup that gives developers access to multiple AI models through a single platform, including lower-cost open-weight systems.

Terms of the deal were not disclosed. The New York Times reported that the transaction is valued at about $7.5 billion, including $1.5 billion for OpenRouter’s founders.

The reported price is far above OpenRouter’s latest funding round. The startup raised $113 million less than three months ago at a valuation of about $1.3 billion. Stripe declined to comment on the transaction.

Why OpenRouter Matters

OpenRouter allows developers to work with multiple AI models without relying on a single provider. The platform has attracted users as companies look for lower costs and more flexibility in how they deploy AI.

Many widely used open-weight models come from Chinese labs such as DeepSeek and Z.ai. They compete with proprietary systems from U.S. companies including OpenAI and Anthropic.

As competition in the AI market intensifies, businesses are weighing model performance against latency and token costs. Routing requests between different models can help companies adjust those costs as pricing and capabilities change.

Stripe Expands Into AI Infrastructure

In a blog post announcing the deal, Stripe said it already works with companies to optimize token costs and route requests between models.

The company said the economics of AI are difficult to manage because models are being released and repriced frequently. OpenRouter’s platform would give Stripe a way to help businesses select models based on factors including cost and performance.

“Stripe is building the economic infrastructure for AI, and together with OpenRouter we’ll help businesses maximize profitability by routing their requests intelligently and spending their tokens efficiently,” Stripe CEO Patrick Collison said.

Stripe Expands Beyond Payments

Stripe was valued at nearly $160 billion earlier this year, with its payments business remaining the core of the company. It has also expanded into adjacent markets, including digital assets and financial infrastructure.

In 2025, Stripe completed its $1.1 billion acquisition of stablecoin platform Bridge. The OpenRouter transaction would add AI infrastructure to that expansion. It would also give Stripe a position in the market connecting AI models with developers and businesses.

OpenRouter Joins Stripe

OpenRouter said in a blog post that joining Stripe would support its goal of allowing multiple AI models and providers to compete for developer demand.

The company said its platform is designed to give developers access to different models rather than making a single system the default. Under Stripe, OpenRouter will continue operating as a platform for routing AI requests across providers.
