Kalshi adds Brier scores and real-time feeds to midterm election contracts
Kalshi launched three transparency features for its 2026 midterm election markets on October 6: Brier scores, low-volume tags, and real-time activity feeds. The platform developed the tools after observing heavier trader participation in local races than national contests. The features arrive less than a month before the November vote as the platform prepares for heightened election trading activity. Kalshi's election trading volume has been growing.
Kalshi is racing to capture retail election traders before Polymarket's November 2 V2 migration can compete for that user base. The Brier scores and activity feeds target data-hungry political traders who currently gravitate toward local races with more movement. Real-time feeds turn Kalshi into a live dashboard rather than a static betting venue, which matters for retention when mainstream attention peaks around Election Day.
The timing is deliberate: the CBS News partnership gives Kalshi broadcast exposure to voters who have never used a prediction market, and these transparency tools give newcomers a reason to stay rather than bounce to sharper-looking platforms. If Polymarket's V2 switchover goes cleanly, Kalshi's feature lead narrows fast.
The transparency launch comes one day after Kalshi's CBS News partnership, making this the second major midterm positioning move by a CFTC-regulated platform this week.
