US Election Prediction Markets Face Legal Clash: States vs. CFTC

Wisconsin thrust prediction platforms into a standstill by reminding voters that betting on elections is prohibited under a 175‑year‑old law.

Legal Tempest Over Election Prediction Markets

Currently, 23 states in the US have statutes banning election wagering, directly targeting leading platforms like Kalshi and Polymarket.

States' Hardline Stances

■Wisconsin strips violators of their right to vote in the election they bet on.

■In Colorado, breaches can lead to 120 days in jail or a $750 fine.

■New York also revokes voting rights, while most other states impose fines and incarceration.

■Nevada and Michigan, via court orders, have forced Kalshi and Polymarket to cease operations in those jurisdictions.

CFTC’s Claim of Sole Federal Authority

■The CFTC classifies all event contracts as swaps, asserting exclusive federal oversight.

■A 2024 federal appeals court ruled that election contracts can be listed, overturning a prior CFTC intervention.

■Legal scholars argue that states can invoke their constitutional “election management” power as a preemption argument.

Company Reactions and Operational Impact

■Kalshi blasted Wisconsin’s law as “blatantly unconstitutional and illegal.”

■Polymarket awaits legal resolution, currently offering only sports‑related contracts.

■Both firms emphasize that as long as they operate on CFTC‑registered exchanges, they remain under federal jurisdiction.

Potential Market Implications

■Inconsistent state regulations could erode investor confidence and limit the platforms’ nationwide scale.

■Sports contracts still dominate volume, preserving liquidity and revenue streams in that segment.

■A clear legal framework for election contracts could unlock a new growth wave for financial derivative markets.

Defne Aydın: The aggressive stance of states on election betting will compress the domestic footprint of prediction‑market platforms in the short term. Yet the CFTC’s assertion of federal jurisdiction promises a standardized regime that could boost sector scalability and liquidity. Investors should hedge state‑specific regulatory risk by diversifying exposures across jurisdictions.
