Stripe confirmed on Wednesday that I was going to buy OpenRouter. While the company did not disclose the price of the deal, sources told the New York Times that it paid $7.5 billion.
That’s a big step forward from OpenRouter. Valuation of $1.3 billion in May. To put that price in context, the founders alone are said to receive $1.5 billion from the sale, more than the startup’s total valuation just three months ago. Investors will get the remaining $6 billion, according to the NYT. Stripe reportedly had to outbid other suitors for the fast-growing startup. including data bricks.
But the question is: what does a payments giant want with a startup that routes messages between different AI models?
The short and fun answer, according to a leaked letter from Stripe’s founders to their investors about the deal, is: uniqueness.
“It is a confusing and perhaps already overloaded term, but we decided that January 1 marked the beginning of the singularity and we have been operating on that basis,” they wrote in the letter. Posted by Eric Newcomerand verified by TechCrunch.
The singularity is supposed to mean the point at which humans and the technology we have created merge to become a new species. This is obviously an ironic reference (as Patrick Collison admitted when using the term it in your company conference in April). We’re pretty sure that Stripe founders, brothers Patrick and John Collison, don’t believe humanity started becoming The Borg eight months ago.
But they have referred to the economic rebound that AI is bringing to Stripe. With AI, more businesses are launching and more of them are using Stripe’s offerings. Stripe says 88% of the Forbes AI 50 are using its products, including OpenAI and Anthropic, as are 100% of the fastest growing Brex startups. No one knows how AI and agents will change the economy of the future, but everyone is sure that they will change it dramatically.
That still doesn’t explain why Stripe wants a company primarily known for helping developers manage the use of their models. Stripe’s founders recognized that their customer bases overlap.
“OpenRouter is exceptionally useful for any developer and Stripe is one of the largest development platforms in the world,” the founders write in their letter. There is no doubt that simply using OpenRouter internally will likely offer significant benefits to Stripe and will also make it easier to implement future model-agnostic agent offerings.
It looks like OpenRouter will continue to operate independently after the deal closes in a few weeks, or so the startup promised in your own blog postsaying that its “product, mission and current commitments remain unchanged.”
Still, so far, most of Stripe’s big acquisitions have been related to helping people collect and manage incoming cash. Buying OpenRouter also seems like a move to the other side of the ledger: expense management, starting with AI expenses.
This acquisition “is Stripe’s deliberate attempt to insert itself into the middle of capital flows in the age of AI,” said PitchBook research analyst Franco Granda.
It joins an unusual range of companies also entering token expense management. Databricks developed its own AI gateway. Rippling just released one focused on Employee AI Spending and ROI. The ramp just launched one, also for AI expense management. And the list goes on.
For Stripe, buying the granddaddy of popular AI developer gateways gives them insight into how coders use AI. But it also gains influence over the demand for AI itself. OpenRouter will give it “some degree of power over providers like the frontier labs themselves, as well as hyperscalers and neoclouds,” Granda said.
It may not be the Borg, but payments plus token expense management and a model router? That’s a lot of power.
