CFTC loses Wisconsin bid to block prediction market enforcement
A US federal judge rejected the CFTC’s bid to stop Wisconsin from enforcing state gambling laws against federally regulated prediction market platforms. Judge William Griesbach denied the CFTC’s request for a preliminary injunction, finding the regulator failed to show it would likely succeed on the merits or face irreparable harm.
The case stems from Wisconsin’s April lawsuits targeting Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase. Wisconsin argues that sports event contracts offered through these prediction markets are essentially unlicensed sports betting under state law.
The CFTC said these sports event contracts qualify as “swaps” under the Commodity Exchange Act, giving the agency exclusive federal authority. But the court ruled the CFTC did not demonstrate the contracts meet the legal definition of swaps. It also said Wisconsin’s gambling statutes are not preempted by federal commodities regulation, implying federal registration does not automatically shield operators from state enforcement when outcomes are tied to sporting results.
The CFTC plans to appeal. The decision also adds to broader US pressure on the regulator: attorneys general from 44 states urged changes to CFTC Rule 40.11, arguing the framework overreaches into areas traditionally regulated by states.
For traders, the ruling increases legal and access uncertainty for prediction markets across states. With courts split—Minnesota temporarily blocked its own prediction market ban while supporting the CFTC’s preemption challenge—operators may face different licensing requirements depending on location, affecting liquidity and participation.
Bearish
This ruling increases regulatory uncertainty for prediction markets in the US, which can reduce platform activity and liquidity in the short term. The key bearish element is that the CFTC’s attempt to establish federal protection for “prediction market” sports event contracts failed in Wisconsin: the court found the CFTC did not prove the contracts meet the legal definition of swaps and held that state gambling statutes are not preempted. That sets a practical risk that other states may pursue similar enforcement.
Traders may react by discounting the probability of “single nationwide rules” and pricing in compliance/access risk. The contrast with Minnesota—where a judge temporarily blocked a ban while supporting the CFTC’s preemption theory—suggests continued legal fragmentation. Historically, when courts issue conflicting rulings on market-access rules (as seen in previous regulatory patchwork episodes in US crypto and derivatives), the near-term effect is often lower participation and wider spreads, because market makers and users struggle to forecast where platforms will be allowed to operate.
Longer term, an appeal could still shift the outcome, but until higher courts settle the interpretation, regional restrictions are likely to persist. That supports a cautious stance: expect event-driven volatility around further legal filings and potential platform access changes.
