Stripe to acquire AI startup OpenRouter for over $8 billion

Aug 19, 2026

Stripe agreed to acquire AI gateway startup OpenRouter on August 19, 2026, in a landmark transaction valued at over $8 billion. The deal represents a massive premium over OpenRouter's $1.3 billion valuation from its May Series B round. By acquiring OpenRouter, which routes queries across 500+ models for over 10 million developers, Stripe embeds itself directly into the transaction path of AI token consumption, combining the gateway with its existing billing, stablecoin, and metering infrastructure.
