The Wisconsin Elections Commission (WEC) voted unanimously to issue a formal public warning on July 22, following a legal memorandum from its own counsel concluding that trades placed on election prediction markets through Kalshi and Polymarket constitute a bet or wager under Wisconsin statute 6.03(2). That statute reads: “No person shall be allowed to vote in any election in which the person has made or become interested, directly or indirectly, in any bet or wager depending upon the result of the election.”
The commission’s position is that a Wisconsin resident who places a trade on a congressional district outcome, a gubernatorial race, or any other election appearing on their ballot is legally disqualified from voting in that race. Voting while disqualified constitutes election fraud under Wisconsin law. The penalty is a felony charge.

The WEC did not file a lawsuit or issue citations. It issued a warning, which is the commission’s way of notifying the public that a legal risk exists under current state law without requiring enforcement action to make the point. The warning carries no automatic penalty of its own. The underlying statute, however, does.
Kalshi called the commission’s conclusion not only wrong but dangerous. The platform described the warning as voter suppression and accused Wisconsin officials of trying to disenfranchise hundreds of thousands of Wisconsin users by implying their legal participation on a federally regulated derivatives exchange could strip their right to vote. Kalshi has consistently maintained across all state-level challenges that its contracts are financial instruments regulated by the Commodity Futures Trading Commission (CFTC), not gambling products regulated by state gaming commissions and that federal preemption overrides state gambling statutes.
Polymarket issued a shorter response, saying it would address the matter through the appropriate legal process. The platform did not use voter suppression framing. Both companies have substantial Wisconsin user bases, with Kalshi’s spokesperson placing its Wisconsin footprint at hundreds of thousands of active accounts.
The WEC’s position is not without legal grounding. Wisconsin statute 6.03(2) was drafted to prevent voters from having a financial stake in an election they participate in, a safeguard against incentive structures that could compromise the integrity of a vote. The text does not restrict its application to traditional bookmakers. It applies to any bet or wager depending upon the result of the election, language broad enough to capture a binary prediction market contract that pays out based on whether a specific candidate wins a specific race.
The October 2024 federal appellate ruling in KalshiEX v. CFTC found that Kalshi’s election contracts were not gambling in the federal legal sense and cleared the way for their continued operation on the CFTC-regulated exchange. Wisconsin’s commission is not challenging that ruling. It is applying state law to conduct that federal courts have found permissible at the federal level, a legal distinction that creates a genuine conflict between state and federal frameworks rather than a simple preemption question.
Wisconsin is now the sixth state to force Kalshi into state-level legal conflict over event contracts, joining New York, Michigan, Illinois, New Mexico, and Washington. Each new state challenge compounds the cost of Kalshi’s multi-front legal defense and narrows the operating assumption that CFTC registration provides a complete shield against state action.
The Wisconsin warning arrives alongside a separate federal challenge. The Stop Trading On Predictions, or STOP, Corrupt Bets Act of 2026 has been introduced in the House of Representatives and would federally prohibit prediction market wagering on elections if enacted.
The Senate has already adopted restrictions barring senators and staff from participating in prediction market betting, a bipartisan measure that signals growing congressional discomfort with the intersection of financial markets and electoral outcomes.
The CLARITY Act, currently targeting an Aug. 7 Senate floor vote before recess, does not directly address election prediction markets. Its passage would establish digital asset market structure rules but would leave the state-versus-federal jurisdiction conflict over election contracts unresolved. Wisconsin’s warning is a preview of how that conflict will continue to evolve regardless of what Congress does with crypto market structure before Aug. 7.
