Stripe has acquired OpenRouter for $7 billion, marking one of the largest AI infrastructure deals to date.

The acquisition comes 90 days after OpenRouter's $1.3 billion Series B round. The deal represents a standard 50x revenue multiple based on the company's $140 million annualized revenue.

OpenRouter's profitability sets it apart in the AI landscape. The model routing platform generates approximately $100 million in annualized gross profit with costs of around $40 million, delivering a 70% gross margin comparable to high-performing public software companies.

The platform now facilitates AI model usage at 250 trillion tokens per month, up from 50 trillion tokens in February. This 5x growth over six months, combined with an 8 million developer base, supported the premium valuation.

Why the acquisition matters

The deal signals Stripe's broader AI infrastructure strategy beyond payments. OpenRouter's API gateway connects developers to over 400 language models across 60+ providers, positioning Stripe at the center of AI model distribution.

For founder Alex Atallah, now a billionaire, the exit validates the model routing layer as a critical piece of AI infrastructure. The acquisition also benefits competing router startups by establishing market valuations.

The timing coincides with intensifying competition in model access layers. OpenRouter recently cut pricing on GPT-5.6 Sol, while Vercel made similar moves on its AI Gateway, indicating the routing market is becoming a pricing battlefield.

Stripe's move contrasts with other AI investment patterns focused on GPU infrastructure, agent labs, or frontier model development. Instead, it bets on the distribution layer that sits between models and developers.

The acquisition reflects where value increasingly accrues in AI: not necessarily in compute or model training, but in the platforms that aggregate and route AI capabilities to end users.
