Researchers open linked dataset of prediction-market trading and outcomes

Published Tuesday, September 29, 2026 · 3:03 AM EDT

Researchers have made a public dataset available that links decentralized prediction-market listings, trades and event outcomes. Their preprint says it contains more than 3.29 million market records and over 1.90 billion order execution records, giving analysts a way to follow markets from creation through settlement. The system matches identifiers across blockchain contracts and other sources, recovers on-chain records and adds incremental updates. The authors demonstrate uses including analysis of NBA forecasts, inflation expectations and disputes over event outcomes. Linking records across those disparate sources remains a central data challenge.
