Surge in Prediction Market Trading Ahead of 2026 Elections
Trading on platforms such as Kalshi and Polymarket has risen sharply this year, covering contests from mayoral primaries to U.S. Senate races. Contracts are priced between 1 and 99 cents, letting participants bet on outcome probabilities. Platforms report that questions with a 60% implied chance materialize at roughly the same rate, and billions of dollars could be wagered on whether Democrats will control the House or Senate.
Background & Context
The growth coincides with President Donald Trump’s push for changes to voter-identification and mail-in voting rules, which he says are needed to curb alleged fraud. Election officials, accustomed to battling misinformation, now confront a financial incentive layer that could shape perceptions of candidate viability.
Data & Statistics
- Kalshi disclosed a three-year suspension and fine for North Carolina congressional candidate Laurie Buckhout (R) for trading on her own race.
- In a Wisconsin gubernatorial primary, markets heavily favored a candidate who ultimately lost, mirroring inaccurate poll results.
- Georgia’s 2026 governor race: Polymarket odds moved from roughly 55-45% to 60-40% in favor of former mayor Keisha Lance Bottoms.
- Georgia Senate race: Polymarket shows Jon Ossoff with a 94-6% lead despite a RealClearPolitics poll average giving him a 7.5-point edge.
Official Statements & Responses
- Jared DeMarinis, administrator for the Maryland State Board of Elections, warned that “this is a troubling trend that election administrators across the nation must deal with.”
- Kalshi says its markets “correlate strongly to outcomes” and that manipulation is deterred by traders who profit from correct predictions.
- Delaware County elections director Jim Allen has asked that prediction-market trading be added to the oath required of polling-place workers; Maryland’s board is considering a similar requirement.
Verbatim Quotes

- “And all of a sudden, they're the front-runner, for no reason other than an outside actor places a large bet on them,” — Ben Schiffrin
Conflicting Reports & Gaps
Prediction markets have sometimes diverged sharply from traditional polls. In Wisconsin, markets favored a losing candidate; in Georgia’s Senate race, a 94-6% market lead may be misinterpreted as certainty. No comprehensive study currently quantifies how market odds influence voter turnout or candidate fundraising.
What’s Next
Litigation over whether states can regulate or ban prediction markets under gambling statutes is already filling courts, and decisions are unlikely before the November elections. Election administrators in multiple states are drafting policies—such as oath amendments and public-education campaigns—to address the “prediction-market phenomenon” before it fully unfolds.
