Stripe has splashed $8bn on OpenRouter as it tries to become the toll booth for the AI economy.
According to the Financial Times, the Irish-American payments outfit, run by Stripe co-founders Patrick Collison and John Collison, said it had agreed to buy OpenRouter on Wednesday. The New York startup runs a marketplace that lets companies switch between different AI models without rebuilding their systems.
Two people familiar with the deal said Stripe is paying $8bn in cash and stock, making it the largest acquisition in the company’s history. The move fits Stripe’s plan to sit between AI companies, compute providers, payment systems and whatever agentic commerce turns into once the hype fog clears.
Stripe co-founder and chief executive Patrick Collison said: “Stripe is building the economic infrastructure for AI, and together with OpenRouter we’ll help businesses maximise profitability by routing their requests intelligently and spending their tokens efficiently.”
Tokens are the units of text, code or data processed by large language models, and AI firms are burning through them at an expensive clip. Stripe, which has dual headquarters in Dublin and San Francisco, has been buying its way into AI and digital assets rather than waiting politely.
The company bought stablecoin outfit Bridge last year, shortly before US President Donald Trump signed the Genius Act in July 2025. That law created a regulatory framework for payment stablecoins, giving Stripe a handy perch in a market that finance types suddenly pretend was obvious.
Stripe bought the billing platform Metronome earlier this year to build “streaming payments,” in which companies pay for AI subscriptions via token use. That model replaces the old “per-seat” subscription wheeze, which makes less sense when machines are doing the clicking.
Collison said: “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.”
In a letter to investors, Stripe said the rise of AI companies had created demand for “better-suited financial tooling.”
It said the same shift had brought “new challenges, such as new kinds of theft and fraud, which require sophisticated advances to be effectively mitigated.”
Stripe is trying to prepare for “agentic commerce,” where AI agents make payments for customers, which sounds grand until one buys 800 subscriptions.
OpenRouter was founded by OpenRouter founder Alex Atallah, who previously founded NFT marketplace OpenSea. Its investors include Alphabet, Sequoia and Andreessen Horowitz.
Atallah posted on X: “OpenRouter will continue to operate as it is: same name, same product, same roadmap, same mission. But now, we will do it faster, and with Stripe’s unparalleled excellence and reach.”
Stripe is not stopping there. It has launched a joint bid with private equity group Advent International to buy US-listed PayPal.
People familiar with the matter said that deal would value PayPal at about $53bn, which would be a whopper even by Stripe’s new standards. Stripe was valued at $159bn in a February tender offer and has repeatedly hinted it is in no rush to go public.
