Stripe wants a foothold in AI, and it is willing to pay dearly for it. The payments company is in talks to buy OpenRouter for about $10 billion, the Wall Street Journal reported. That is a staggering price for a startup valued at just $1.3 billion in May. The talks are preliminary, and could still fall apart or draw a rival bidder.

OpenRouter is a marketplace for AI models. Founded in New York in 2023, it lets developers reach more than 400 large language models from around 70 providers through one interface. It routes each request to the cheapest or best option. Its co-founder Alex Atallah, who previously built the NFT marketplace OpenSea, calls it “an AI equivalent of Stripe”.

That pitch is the whole story. As AI bills climb, companies want to spread their work across many models rather than lock in with one lab. OpenRouter sits in the middle. It is the toll booth between the labs that build the models and the businesses that use them. Those can be open models, or closed ones from OpenAI and Anthropic.

Stripe, valued at $159 billion, wants to own that toll booth as it pushes beyond payments into AI infrastructure. The two already work together, as OpenRouter uses Stripe to bill its own customers.

Stripe’s second big swing

This is not Stripe’s only large bet in play. It is separately chasing PayPal with the private-equity firm Advent. That unsolicited offer valued PayPal at roughly $53 billion, and PayPal rebuffed it as too low. Nor is Stripe the only suitor for OpenRouter. Databricks held early talks too, The Information reported, and the Journal says other big tech firms circled.

Is a router worth $10bn?

The price has raised eyebrows. OpenRouter has doubled its value in a year. It would now fetch nearly eight times its May figure, at a moment when AI deals are running hot. Sceptics question whether a model router has durable value. If AI tokens become cheap and plentiful, the argument goes, why pay to route between them?

On Hacker News, one commenter noted the software itself would be cheap to rebuild. The value, they argued, is the existing customers and the switching costs. Once a company’s logs and budgets sit in one place, moving is painful. The investor Alex Konrad sees a coming clash. “The AI showdown nobody is talking about yet is Ramp vs. Stripe,” he wrote.

For Stripe, the logic is defensive as much as offensive. Whoever controls how companies buy and route AI controls a fast-growing slice of their spending. Stripe would rather own it than watch a rival take it. The catch is that this is still talks, not a deal. A transaction could come within a month, the reports say, or not at all.
