What happened
Stripe Inc. has agreed to acquire OpenRouter Inc., an AI model routing startup, in a deal reported at $7.5 billion or more (with varying reports citing $7.5 billion, above $8 billion, or above $7 billion). Closing is expected within weeks. OpenRouter was founded in 2023 by Alex Atallah and Louis Vichy and has about 90 employees.
Why it matters
OpenRouter routes requests across more than 400 AI models from over 80 providers, choosing the best fit based on complexity, price, and speed—meaning businesses can switch AI providers without changing their code. With more than 10 million developers and companies using it and daily volume running past 10 trillion tokens, the acquisition extends Stripe's strategy of building economic infrastructure for AI spending, following similar deals for billing and blockchain infrastructure over the past two years.
What to watch
OpenRouter's product, name, and roadmap remain unchanged, and routing decisions will continue to prioritize what is best for the customer. The company's annualized revenue was near $50 million in March (up from roughly $19 million at the end of 2025). Stripe has been OpenRouter's payments provider since at least January and previously shipped a token billing integration with the startup.

Stripe's acquisition of OpenRouter marks a significant deepening of the payments giant's strategy to become the economic infrastructure layer for AI. Over the past two years, Stripe has systematically acquired companies that handle the business-side plumbing of AI spending rather than betting on AI models themselves. In December, the company announced its acquisition of Metronome Inc., a usage-based billing provider (closed in January), and previously bought stablecoin infrastructure firm Bridge Ventures Inc. for $1.1 billion in October 2024 (completed in February) and crypto wallet developer Privy Inc. in June. Patrick Collison, Stripe's co-founder and chief executive, framed metered pricing—the business model shift required by AI's token-based consumption—as potentially as significant as the arrival of SaaS.
OpenRouter's core value lies in its neutrality: it acts as a routing layer that lets developers and businesses optimize their inference spending across hundreds of models without vendor lock-in. With more than 10 million users processing over 10 trillion tokens daily, the startup has become a critical piece of the AI supply chain. Stripe has already been OpenRouter's payments provider and shipped a token billing integration with the startup, suggesting a natural fit. The two companies have also crossed paths through venture backing—Andreessen Horowitz led OpenRouter's seed round and co-led its Series A, and Nvidia's NVentures participated in the recent $113 million Series B (which valued OpenRouter at $1.3 billion in May).
Martin Casado, a general partner at Andreessen Horowitz, called the combination "inevitable" and positioned tokens as a new universal medium of value exchange, likening OpenRouter's role to that of payments infrastructure in the previous era of the internet. The acquisition signals that as AI spending scales, the companies best positioned to profit may not be model makers but rather the infrastructure that helps businesses route, meter, and pay for compute efficiently.
