Prediction markets

The next frontier of financial markets

A joint report ยท Published Dec 2025

Prediction markets are becoming the world's most accurate information network.

In under two years, monthly notional volume in prediction markets has surged 130x, from under $100M to $13B+.

But volume is only part of the story.

Prediction markets are evolving into real-time information systems, event-level hedging tools, and a new asset class pricing everything from elections and inflation to AI breakthroughs.

In this report, Dune and Keyrock map the prediction-market ecosystem end-to-end, from its historical roots and design space to its explosive growth and emerging use cases, delivering one of the first full-stack, data-driven views of this rapidly evolving market layer.
