Stripe's $7.5 Billion Bet on the AI Model Routing Layer

Fintech giant Stripe is acquiring OpenRouter, a leading artificial intelligence (AI) model gateway, in a deal reportedly worth $7.5 billion. That's nearly six times the $1.3 billion valuation estimated by The New York Times following its latest funding round in May. The premium is due in part to Stripe having outbid other tech players, including Databricks, for the company.

OpenRouter gives developers access to nearly any model from more than 80 providers while taking a small cut of every bill. The company now processes more than 10 trillion tokens per day, roughly triple its pace in May, for a community of over 10 million developers and companies.

How OpenRouter earns its keep

OpenRouter charges a 5.5% take rate on the spending that flows through its platform. While the company is private, some estimates put annualized revenue at $140 million in July, up from nearly $50 million at the start of the year.

Stripe, which is also privately held, built its business helping companies collect money online. Now it can do the same with tokens, collecting from developers and AI-native start-ups as they scale.

Both companies are toll collectors, and this acquisition will expand Stripe's currency base. Where it typically spends to grow its transaction volume, these tolls will rise on their own as AI adoption spreads. Stripe's fraud screening also helps prevent the stolen-card purchases and token reselling that plague small AI marketplaces.

What a router does depends on who you ask. Today, OpenRouter operates primarily as a gateway. Developers choose their own model, and the platform forwards the request and takes its fee. Most users want that control and know which models fit which tasks.

The company's nascent Auto Router tool reads each prompt and picks the model itself. That fits the needs of large enterprises where otherwise, thousands of employees would each need to know which model suits which task and keep up as new models arrive every few months.

If enterprise AI adoption is going to proliferate in the coming years, developing automatic routing capabilities could be quite valuable. Whichever company eventually gets it right could become the provider of choice.

The Cloudflare precedent

Cloudflare (NYSE: NET) spent years providing the free security layer that millions of websites sat behind, then converted that traffic into paid computing and security contracts over the course of a decade. Its AI Gateway now does similar work, sitting in front of model calls.

OpenRouter is somewhere close to where Cloudflare stood before its enterprise business took off. Its role as a distribution channel was on display just days after the announcement. An anonymous model called Ox Alpha appeared and quickly became the most-used model on OpenRouter, processing 23.2 trillion tokens in less than a week.

The business model has its challengers. Amazon, Microsoft, and Alphabet all bundle similar multimodel routing for free.

It looks like Stripe is betting on the growth of AI-native start-ups and the long-term potential of building an automated routing business. In its recent investor letter, the fintech company argues developers will soon need to manage intelligence pipelines the way Stripe already lets them manage revenue pipelines.
