Summary
Stripe is finalizing its purchase of AI model marketplace OpenRouter for more than $8 billion. The deal positions Stripe to own the model-routing and payments layer for the AI agent economy — OpenRouter lets developers route traffic across 400+ AI models, acting as "Stripe for AI." It is also minting quick wins for venture backers: Andreessen Horowitz and Menlo Ventures are poised to turn sub-two-year investments into ~$2 billion combined. The acquisition follows Stripe's run of M&A (Bridge stablecoin, Privy wallet, PayPal bid with Advent).
