Stripe has acquired OpenRouter, the model-routing API platform, for $7 billion, just 90 days after OpenRouter's $1.3 billion Series B. The deal values the company at a 50x multiple on its last reported annualized revenue of $140 million. OpenRouter's business economics are exceptional: it operates with $40 million in annualized costs to serve its model-routing product, yielding approximately $100 million in annualized gross profit and a 70% gross margin—comparable to top-tier public software firms.
OpenRouter serves as an aggregation layer for multiple large language models, routing 250 trillion tokens per month across 8 million developers. The platform has grown token volume 5x in six months and commands a broad developer base, making it a high-velocity infrastructure asset with strong retention. This valuation suggests that model routing—the intermediary layer between app developers and frontier LLM providers—is becoming a strategic competitive advantage.
For architects shipping AI systems, the Stripe acquisition signals that token-brokerage efficiency and developer lock-in at the routing layer drive significant M&A multiples. Model routing is becoming less a tolltaking layer and more a core dependency, but recent pricing cuts from both OpenRouter and Vercel AI Gateway indicate margin compression is a real risk if the market commoditizes further.
