CFTC Sues Minnesota Over SF 4670 Prediction Market Ban

industry

Minnesota's growing fight against prediction markets has reached a historic turning point by signing off Senate File 4670 (SF 4670). However, the Commodity Futures Trading Commission (CFTC) has sued the state of Minnesota, Gov. Tim Walz, and Attorney General Keith Ellison to stop the enforcement of the recently signed bill.

The lawsuit marks the first modern case involving the federal government suing a state to protect prediction markets. Moreover, the legal clash could reshape how regulators treat these platforms nationwide. 

The dispute also adds new pressure on the relationship between federal oversight and state-level Minnesota gambling laws.

Why the CFTC Is Suing Minnesota Over SF 4670

The CFTC filed its lawsuit after Minnesota approved SF 4670, a measure targeting prediction market operators. Gov. Walz officially signed the legislation into law in May 2026. The measure will take effect on Aug. 1, 2026.

Federal regulators argue that the state cannot prohibit federally regulated event contracts. According to the CFTC, prediction markets fall under federal commodities law instead of state gambling statutes. Therefore, the agency claims Minnesota violated federal preemption rules by attempting to block these markets.

The lawsuit specifically names Walz and Ellison because both officials play direct roles in enforcing the law. The CFTC wants the court to stop the state from implementing the legislation before the effective date arrives.

The case also reflects rising tensions between states and prediction market operators. Several lawmakers believe these products resemble sports betting markets. However, prediction market companies continue describing their offerings as financial derivatives instead of wagers.

As a result, the lawsuit has become one of the most significant regulatory disputes involving US online sportsbooks and event contracts.

Key Provisions of SF 4670

SF 4670 directly targets prediction market platforms operating within Minnesota. The law bans contracts tied to sporting outcomes and election-related events.

Additionally, the legislation prevents companies from offering event-based contracts without authorization under state law. Minnesota lawmakers argued the platforms operate outside existing gaming rules while avoiding taxes and licensing requirements.

The law also gives state authorities stronger enforcement powers against operators offering unauthorized contracts to Minnesota residents. Critics of prediction markets believe the platforms create loopholes within existing Minnesota gambling regulations.

Supporters of the law also raised concerns regarding consumer protections and responsible gaming safeguards.

Prediction Markets and the CFTC Intensify Their National Offensive

The Minnesota dispute follows months of escalating battles across the country. Several states have recently moved against prediction market operators.

Nevada has aggressively challenged sports-related event contracts. New Jersey regulators have also scrutinized prediction market activity.

Meanwhile, tribal gaming groups in New Mexico have pushed back against companies such as Kalshi. Wisconsin also recently delivered another setback for Kalshi after a federal judge allowed the Ho-Chunk tribe's case to continue.

At the same time, the relationship between the CFTC and prediction markets remains complicated. While the agency currently opposes state-level bans, it has also challenged prediction markets federally in previous disputes. Most notably, the CFTC has continued fighting Kalshi over congressional election contracts.

However, the Minnesota lawsuit centers on federal jurisdiction instead of support for prediction markets themselves. In this case, the CFTC is defending its authority to regulate federally approved event contracts without state interference.

Congress has also intensified pressure on the industry. Several House lawmakers recently pushed for tighter federal oversight of prediction markets. They've also pushed for public officials and government personnel from participating in prediction markets.

Some lawmakers specifically urged regulators to scrutinize sports-related contracts more aggressively. Critics believe the products function similarly to US online sportsbooks while bypassing state gaming laws.

The Bigger Picture Behind Federal and State Authority

The Minnesota lawsuit could establish a major precedent for future prediction market regulation. Courts must now determine whether federal commodities law overrides state gambling authority.

If the CFTC wins, states may lose the ability to independently regulate certain prediction market products. That outcome could significantly weaken future state enforcement efforts.

However, a Minnesota victory could strengthen the position of states seeking tighter control over prediction markets. Other jurisdictions would likely pursue similar legislation afterward.

The outcome may also influence broader discussions involving online gaming, sports wagering, and financial regulation. Consequently, the case could shape the future relationship between state gaming agencies and federal market regulators for years.
