Kalshi and Polymarket Data, Unified on Dune — a New Macro and Equity Signal Source

Prediction markets now price the events that move macro and equity portfolios — Federal Reserve decisions, earnings outcome thresholds, tariff policy, M&A approvals, WTI and SPX settles, geopolitical chokepoints. Each contract is a probability set by participants with capital at risk, updated continuously, and resolved against a known outcome at settlement.

Pulling that data into a research stack used to mean months of upstream engineering — venue-specific APIs, raw onchain indexers, schema reconciliation, and ongoing maintenance through every venue upgrade. We've absorbed that work.

The result: a clean equity and macro signal source — hourly candlestick prices, per-fill trades, position-level data, and resolution outcomes across both venues, with four years of resolved history behind it.

Kalshi and Polymarket, unified, live on Dune today.

"We apply knowledge from prediction markets to equities — there's very interesting timing capability in markets on topics like tariffs and earnings." — Quant Researcher, Multi-strategy hedge fund
