A 50-person company routing 25 trillion tokens a week just got a $7B price tag. The interesting part isn't the price — it's what the traffic behind it now looks like.
Stripe has reportedly agreed to acquire OpenRouter at a valuation above $7 billion. The company was founded in 2023 and has around 50 people.
// How it got here
It doesn't train models or own GPUs. It solved an integration problem — every vendor with its own API format, billing rules and rate limits — by putting one endpoint in front of all of them.
That went nowhere for the first year, until open-weight models caught up. Annualized inference spend on the platform went from $10M in late 2024 to an estimated $1B this March.
// The number that stood out to us
Before February, Chinese open-weight models were under 2% of tokens on OpenRouter. They're now above 60%, and 47% of the developers driving that volume are in the US.
// On the price
At roughly $140M in annualized revenue, $7B is about 50x. That's not what you pay for a 5.5% take rate. Stripe spent this year building for a world where agents book the flight, compare the prices and place the order — agentic settlement protocols, a delegated wallet built on its consumer base.
Alex Atallah has described OpenRouter as the Stripe of AI: one settles money, the other settles tokens. Owning both puts two meters in the same place — what a task costs to think, and what it costs to act.
// Where we think this goes
If that's the direction, the number that matters shifts from cost per token to cost per task. And with open weights, the levers behind that number belong to whoever is serving: quantization, batching, KV cache policy, failover, how much capacity you hold ahead of demand. That's where the cost and most of the incidents actually live.
Routing got easy. The decisions behind the endpoint didn't. That's the part we work on.
