aakashgupta · x · 2026-08-17

Analysis of Stripe's 140x multiple acquisition of OpenRouter. OpenRouter uses a 'pass-through pricing + top-up fee' model: it passes model costs directly to users, taking a 5.5% fee when customers load credits. This yields nearly double the margin of Stripe's core 2.9% + 30¢ product, creating strong cash flow.
