In brief
- Stripe finalized an agreement to acquire OpenRouter for more than $7 billion.
- OpenRouter routes traffic from around 8 million developers to more than 400 AI models and takes about 5% on the inference spend passing through it.
- Stripe already processed OpenRouter's payments, so the deal folds AI metering and AI billing into a single pipeline it owns end to end.
Stripe has finalized an agreement to buy OpenRouter for more than $7 billion, according to Bloomberg, three months after the AI routing startup raised $113 million at a reported $1.3 billion valuation.
The Wall Street Journal reported talks last month at a figure closer to $10 billion, so somebody negotiated.
OpenRouter's annualized revenue was around $50 million in March, per Sacra estimates. That puts the deal somewhere near 50 times revenue, which is not a multiple anyone pays for cash flow.
What Stripe is buying
So what is Stripe, a company known for processing digital payments, actually buying? Position. OpenRouter sits between roughly 8 million developers and more than 400 AI models, giving them one API key instead of a dozen separate integrations. It owns no GPUs, trains nothing, and takes about 5% of the value paid per overall usage.
Stripe already handled OpenRouter's invoicing and tax, which makes this a vendor buying its own customer. Now the routing decision and the invoice sit inside the same company: OpenRouter picks which model answers a request and what it costs, Stripe collects on it.
