Traders can now access data from both Kalshi and Polymarket in one place on Dune Analytics. The integration pulls together four years of historical market data, giving users clean macro and equity signals without jumping between platforms. It's a move that consolidates two of the biggest prediction-market datasets under one dashboard.
What the unification delivers
Dune's new combined view covers event contracts from both Kalshi and Polymarket. That means traders can compare sentiment on everything from Federal Reserve rate decisions to election outcomes without stitching together separate feeds. The platform says the data is cleaned and normalized, so signals like price movements and volume shifts are ready to use in queries and visualizations.
Before this, anyone tracking both markets had to pull data manually or rely on third-party aggregators. Now a single query on Dune can show how Polymarket's binary contracts and Kalshi's event-driven markets move in relation to each other. That's useful for traders who want to spot divergences or confirm trends across the two biggest regulated and unregulated prediction platforms.
Four years of historical depth
The data goes back to 2020, covering a period that includes the 2020 US election, the COVID-19 pandemic's market impact, and multiple Federal Reserve tightening cycles. Having that span available in one clean dataset lets traders backtest strategies or analyze how prediction markets reacted to past events. Dune didn't specify how many individual contracts are included, but the historical range is enough to capture major macro shifts.
For equity traders, the macro signals from Kalshi are particularly relevant. Kalshi lists contracts on economic indicators like CPI releases and unemployment claims. Polymarket, meanwhile, covers a broader set of event bets including politics and pop culture. The unification means a trader can check, say, a Kalshi inflation contract alongside Polymarket's election odds in the same dashboard.
Prediction-market data has become a staple for some hedge funds and retail traders looking for alternative signals. But until now, the data was fragmented. Kalshi is a regulated CFTC exchange, while Polymarket operates as a crypto-based platform. Their datasets have different structures and update frequencies. Dune's team handled the normalization, so users don't have to.
The move could also attract more developers to build tools on top of the combined data. Dune is known for its community-driven dashboards, and the new unification opens the door for custom queries that merge prediction-market sentiment with other on-chain or economic data. It's not clear whether Dune plans to add more prediction markets in the future, but the addition of Kalshi and Polymarket gives traders a solid starting point.
For now, the unified data is live and free to query. Traders can start pulling signals immediately. The next question may be how quickly the data gets updated during fast-moving events—and whether Dune will add historical data from other prediction platforms down the line.
