Payment Giant Stripe to Buy AI Model Platform OpenRouter for $7.5 Billion

Stripe has announced its intention to acquire OpenRouter, an artificial intelligence model platform, as part of its broader expansion into the AI sector. While the transaction terms were not disclosed, people familiar with the matter said the purchase price is approximately $7.5 billion, of which $1.5 billion will be allocated to OpenRouter's founders. The acquisition comes less than three months after OpenRouter completed a $113 million funding round that valued the company at roughly $1.3 billion. Stripe declined to comment on the deal.

OpenRouter is widely used by developers seeking access to AI models, particularly those considered non-proprietary and free to use. Many of these open-weight models originate from Chinese laboratories such as DeepSeek and Z. ai, and are often more cost-effective than proprietary models from U. S. companies like OpenAI and Anthropic, making them appealing to developers. In an official blog post, Stripe said it has been working with companies to "optimize their token costs and route tokens efficiently," where tokens serve as a metric for AI model usage. Stripe noted that managing AI costs relative to performance is challenging due to the rapid pace of model releases and repricing.

Stripe is one of the world's most valuable startups, with a valuation approaching $160 billion as of early 2026, largely driven by the widespread adoption of its online payment technology across numerous markets. In 2025, Stripe acquired the stablecoin platform Bridge for $1.1 billion, underscoring its commitment to the cryptocurrency space. The acquisition of OpenRouter marks another significant step for Stripe in the rapidly growing AI market.
