Stripe confirmed on Wednesday that it is buying OpenRouter, the startup that routes AI prompts between different models, without disclosing the price. Sources told The New York Times that the payments giant paid $7.5 billion — a steep climb from OpenRouter's $1.3 billion valuation in May.
The founders alone will reportedly receive $1.5 billion from the sale, more than the startup's entire valuation three months ago, while investors split the remaining $6 billion. Stripe had to outbid other suitors for the fast-growing company, including Databricks.
The most talked-about explanation came in a leaked letter from Stripe's founders to investors: the company decided that "January 1 marked the beginning of the singularity" and has been operating on that basis. The letter, published by Eric Newcomer and verified by TechCrunch, frames the deal as a bet on AI's explosive trajectory — and triggered a wave of skepticism about whether singularity rhetoric masks a straightforward infrastructure play.
OpenRouter sits at a chokepoint of the AI economy, steering traffic between competing models the way payment rails steer money. For Stripe, owning that routing layer positions it to capture the growing market of paying for AI inference itself.
