Stripe will acquire OpenRouter for $7.5B

Stripe has agreed to acquire OpenRouter for about $7.5 billion, roughly six times the startup’s $1.3 billion valuation from a Series B three months earlier. OpenRouter, founded in 2023, offers a single API that routes requests to more than 400 large language and open-weight models (GPT, Claude, Gemini, DeepSeek, Z.ai, etc.), claiming over 10 trillion tokens processed daily and roughly 10 million developers using its service; customers include Nvidia and Zoom. Stripe outbid competitors including Databricks, and the deal pays OpenRouter founders $1.5 billion while investors receive about $6 billion.

Stripe frames the purchase as extending its AI economic infrastructure: OpenRouter plugs into Stripe tools for token billing (Metronome), micropayment settlement (Tempo) and agent wallets (Privy), letting Stripe both route model traffic and bill token usage in real time. The deal is notable because a payments company gains control over which models get called, raising immediate neutrality concerns. OpenRouter’s value rests on impartial routing; ownership by a firm that profits from payment volume and has partnerships (including with Google) creates incentives that could shift default routing, pricing or provider preference. The companies have not explained how OpenRouter’s independence will be preserved, leaving developers uncertain about routing logic, pricing changes, and potential single-point-of-failure risks.
