Stripe is in talks to acquire OpenRouter in a deal that could value the AI-model marketplace at roughly $10 billion, the Wall Street Journal reported late Thursday. An agreement could be announced soon — though the Journal notes the talks may still fall apart, or attract another buyer. Several other large technology companies have reportedly looked at bidding.
The markup
OpenRouter was valued at about $1.3 billion in May, in a $113 million Series B led by CapitalG, Alphabet's growth fund, with Nvidia among the participants. A $10 billion price would be roughly eight times that mark, set about two months ago. Stripe itself was valued at $159 billion earlier this year.
What OpenRouter does
Founded in 2023 by OpenSea co-founder Alex Atallah and based in San Francisco, it is a single API gateway onto hundreds of models — proprietary and open-weight — from OpenAI, Anthropic, Google and the open-source labs. Developers can compare models, switch providers and route traffic without rewriting anything. More than five million developers use it.
Why a payments company wants it
Because OpenRouter is already a metering and billing layer that happens to be pointed at models. Every routed call is a measured, priced, settled transaction — and OpenRouter runs those payments on Stripe today. Buying it puts Stripe at the toll booth between developers and inference, which is the position it wants as software agents start spending money autonomously.
The caveat
This is reporting on negotiations, not a signed deal. No terms have been confirmed by either company, and neither has commented. What is not in doubt is the direction of the price: a routing layer that was worth $1.3 billion in May is being discussed at eight times that in July.
