CFTC Fails to Block Wisconsin Prediction Market Enforcement

A federal judge in Wisconsin denied the CFTC’s request for a preliminary injunction against the state’s enforcement of gambling laws on prediction market platforms. This ruling permits Wisconsin to proceed with its cases against companies offering sports event contracts.

What Happened

U.S. District Judge William Griesbach of the Eastern District of Wisconsin rejected a request from the Commodity Futures Trading Commission (CFTC) to prevent Wisconsin from applying its state gambling laws to federally regulated prediction market platforms. The CFTC had sought a preliminary injunction to shield platforms including Kalshi, Polymarket, Crypto.com, Robinhood, and Coinbase from state enforcement actions, according to Crypto News.

Wisconsin initiated federal legal action in April 2026, alleging that sports event contracts offered by these platforms constitute unlicensed sports betting. Judge Griesbach determined that the CFTC had not demonstrated a likelihood of success on the merits, irreparable harm, or a favorable balance of equities, which are all prerequisites for a preliminary injunction, as reported by Bloomberg Law.

Key Details

• Judge William Griesbach denied the CFTC’s request for a preliminary injunction against Wisconsin, stating that sports event contracts may fall within Wisconsin’s commercial gambling laws, according to Crypto News.
• The court also rejected requests by Kalshi and Crypto.com to intervene and seek preliminary relief in the federal dispute, as reported by Gaming Intelligence.
• The judge concluded that the CFTC had not shown that sports contracts meet the Commodity Exchange Act’s definition of swaps, which was sufficient grounds to deny the injunction, according to Crypto News.
• Wisconsin’s Attorney General, Josh Kaul, described these contracts as sports bets disguised as financial products, stating that “These companies’ alleged facilitation of sports betting in Wisconsin should be shut down,” according to Crypto News.

Why It Matters

This ruling suggests that federal registration under the CFTC’s authority does not automatically protect a platform from state gambling enforcement, particularly when contracts are linked to sporting outcomes, according to Crypto News. The decision intensifies a broader challenge to the CFTC’s efforts to establish national control over prediction markets, a position that 44 state attorneys general have urged the regulator to reconsider.

Attorneys general, led by Ohio Attorney General Andy Wilson, argued that the CFTC’s proposed amendments to Rule 40.11 exceed its authority under the Commodity Exchange Act and infringe upon state-level gambling oversight. This dispute highlights a potential lack of consistent national standards for prediction markets, as access for U.S. users may increasingly depend on state-specific regulations rather than a unified federal approach, according to Crypto News.

What’s Next

A CFTC spokesperson indicated the agency’s disappointment with the Wisconsin decision and confirmed plans to appeal the ruling, according to Crypto News. The outcome of these appeals could determine whether Wisconsin’s state lawsuits proceed and whether the affected platforms must cease offering sports contracts within the state.
