When we covered the reported OpenRouter acquisition on 17 August, only a range was on the table: "over 7 billion dollars". Since 20 August the figures are concrete.
Stripe is acquiring OpenRouter for 7.5 billion US dollars. According to heise, 1.5 billion of that goes to the founders and 6 billion to investors, who had previously put in a combined 164 million dollars. The deal is expected to close in the coming weeks.
OpenRouter builds no models of its own. The platform sits one layer above: it routes requests to more than 500 models from different providers, makes their prices and response times comparable, and handles billing centrally. The company says more than ten million people use it. Customers who top up an account can switch off automatic charging, keeping a level of spending control the model providers themselves do not offer.
That is what makes the number plausible. For a payments company, a business that bills per request is not a foreign industry — it is its own business in new clothing. The value lies less in model routing than in the billing relationship with developers who spread many small amounts across many providers every day.
The price trajectory shows how fast this layer was repriced. In May, OpenRouter closed a 113 million dollar Series B at a reported 1.3 billion valuation. Three months later the contract says five times that. The company is only three years old.
For existing users, Stripe is promising continuity for now: "Same mission, same name, same product, same roadmap." Whether a neutral routing layer stays neutral once it belongs to one of the largest payment providers is the open question — and it will only be answered by the pricing of the coming months.
