Stripe buys OpenRouter for a reported $7.5B after a $1.3B May round

Stripe has agreed to buy OpenRouter, the gateway that sits between developers and more than 400 AI models. Both companies announced the deal on August 19, and neither disclosed what it cost. Sources told the New York Times the price was $7.5 billion, TechCrunch reported.

That number matters because OpenRouter raised at a $1.3 billion valuation in May, when CapitalG led a $113 million Series B, according to SiliconANGLE. The reported sale price is close to six times that, three months later. TechCrunch, citing the Times, said the founders alone stand to receive $1.5 billion, with $6 billion going to investors.

The product itself is one endpoint. Developers point their code at OpenRouter once, and behind it sit more than 400 models from over 80 providers, per Stripe’s announcement. Requests get scored on complexity, price and speed, then sent to whichever model fits, and switching providers takes no code change. OpenRouter says it now processes more than 10 trillion tokens a day for over 10 million developers and companies.

What nobody has is a confirmed price. The reported figures don’t agree with each other, and SiliconANGLE collected the spread.

Stripe’s stated case is that tokens are now the line item businesses care about, which puts routing next to billing rather than next to model research.

Tokens are the central currency for companies building with AI, and it’s clear that the real-world economic potential will depend on making good use of scarce compute resources.

That fits a two-year pattern. Stripe announced a deal for usage-based billing company Metronome in December and closed it in January, SiliconANGLE reported, after paying $1.1 billion for stablecoin infrastructure firm Bridge in October 2024. Crypto wallet developer Privy followed the next June. Stripe has also been OpenRouter’s own payments provider since at least January, so the two already shipped a token billing integration together.

The sceptical reading is that routing isn’t where the money sits, and Semafor argued that’s precisely the point. If routing commoditises into finding the cheapest model that clears a quality bar, OpenRouter can chase customer relationships instead of the margin on each API call. Stripe can then monetise everything around it: billing, tax, fraud, stablecoin settlement and treasury. That is a familiar answer to the question of which layer of the AI stack keeps the money.

Andreessen Horowitz, which funded OpenRouter’s seed round, made the case in public the same day. General partner Martin Casado wrote that tokens have become a new, universal medium of value exchange. Read that way, the neutral layer that routes and clears them matters more than the fee it takes on the way through.

The routing becomes the unsung enabler of the whole story, just like payments was, for the previous era of the internet.

Treat the economics carefully, though. SiliconANGLE reported that about 5% of the inference spending running through the platform stays with OpenRouter, and neither company’s own announcement mentions a take rate. The same goes for the price: $7.5 billion, $8 billion and $10 billion, none of them confirmed by Stripe or OpenRouter. If you’re modelling your own bill, the gap between model prices at the same benchmark score is the number that actually moves it.

OpenRouter says the transaction is subject to customary closing conditions and should close in the coming weeks. In its own post the company promised the same mission, same name, same product and same roadmap, and said routing decisions stay driven by what’s best for the user. That promise is the thing to watch. A neutral layer owned by a payments company gets tested the first time a provider wants better placement.
