Kalshi and Polymarket Secure Preemptive Victory Against Minnesota’s Prediction Market Ban

Kalshi and Polymarket’s first win against Minnesota’s impending prediction‑market ban comes with a preliminary injunction from U.S. District Court for the District of Minnesota’s Judge Katherine Menendez, bolstering the firms and the CFTC.

Legal Framework: CEA Preemption

■Minnesota’s “Prediction Market Ban” law is deemed to clash with the Commodity Exchange Act (CEA).

■Judge Menendez ruled the plaintiffs’ preemption claim is “likely to succeed.”

■The law targets “event contracts” that could be classified as “swaps.”

CFTC’s Role and Contract Definition

■The CFTC classifies such contracts as “swaps,” asserting regulatory jurisdiction.

■Examples like “Love Island” win predictions illustrate potential overlap, yet a targeted injunction remains complex.

■“Irreparable harm” to Kalshi and Polymarket was highlighted, underscoring the stakes.

Market Reaction: User Flow and Liquidity

■Binance maintained ~55 % of user funds and ~24 % of spot volume, while others saw net outflows.

■The injunction remains in place until a “final decision” is reached, prompting investors to reassess risk profiles.

Future Scenarios: Law vs. Market

■The law is temporarily suspended pending a full trial.

■Kalshi and Polymarket are expected to succeed in the final case.

■Minnesota may reconsider state‑level measures against federal regulation.

Markets view this as a turning point for regulatory arbitrage and market resilience within the crypto ecosystem. The CFTC’s robust defense could prompt reevaluation of similar laws in other states. While legal uncertainty may dampen short‑term confidence, it ultimately strengthens regulatory compliance for market infrastructure.
