Frequently asked questions

On Kalshi, the dashboard for the Chicago mayoral election tracks the evolving probabilities of different candidates winning.

Currently, prediction market odds often reflect a different assessment than traditional polling averages for the Chicago mayoral election. While polls aim to capture a snapshot of current voter intentions, this market aggregates the informed opinions of traders who have skin in the game. Discrepancies can arise from factors like differing methodologies, weighting of respondents, and the ability of market participants to incorporate a wider range of information, including fundraising data, endorsements, and real-time campaign developments. These differences highlight how prediction markets can offer a unique perspective on the likely outcome.

This market resolves around Feb 23, 2027, with the outcome confirmed once the event is verifiable from credible public reporting. Resolution will be based on the official results announced by the Chicago Board of Elections, determining which candidate receives the most votes in the election. The market will settle to 100 for the winning candidate and 0 for all others. Traders should monitor news sources for the official announcement to understand when this market will be finalized.

Several signals or events could significantly move this market before Feb 23, 2027. Major endorsements from influential figures, significant shifts in fundraising totals, and the release of new, impactful polling data are all likely to cause price adjustments. Unexpected controversies involving candidates, debates with clear winners and losers, and changes in voter turnout projections could also drive trading activity. Any event that alters the perceived likelihood of a candidate winning the Chicago mayoral election will be reflected in the prices on Kalshi.
