Stripe has just made one of the biggest AI acquisitions yet, buying OpenRouter for around $7.5 billion — a company that was valued at just $1.3 billion only months earlier. So what exactly is Stripe buying, and why has OpenRouter become so valuable so quickly?

In this episode of the Market Maker Podcast, Anthony Cheung and Stephen Barnett break down OpenRouter’s extraordinary rise, how its platform connects businesses to hundreds of different AI models, and why the economics of AI could increasingly favour the platforms routing intelligence rather than the companies building the models themselves.

We also unpack the remarkable story of Stripe, founded by Irish brothers Patrick and John Collison, which now processes payments equivalent to around 1.6% of the entire global economy. We explore how Stripe became a critical part of the internet’s financial infrastructure, and why its latest acquisitions point to much bigger ambitions across AI, payments and agentic commerce.

From venture capital and AI valuations to network effects, business moats and the future of online commerce, this is the business behind Stripe’s $7.5 billion bet on the AI economy.
