Episode 01: Compute Markets

Neil Bradford shares a London taxi with David Lopez Mateos, CTO of Compute Desk, to decode one of the fastest-growing markets in the world: compute. David explains what compute actually is, why GPU-hours already trade at around $1 trillion a year, and why the financial market around it is still being built.

About the show

The Knowledge takes its name from the test every London black-cab driver must pass: years spent learning every street, so they never need a map.

The show applies the same idea to markets. Neil Bradford, founder and CEO, General Index, rides with the people building them and asks the plain questions: what is being traded, how big is it, and how does it get a price.

General Index publishes FCA-regulated energy benchmarks built on real market activity, with 6,000+ daily prices across crude oil, refined products, natural gas and energy transition.
