U.S. court backs Kalshi, reinforcing CFTC’s push for federal control over prediction markets

A U.S. federal appeals court has ruled in favor of Kalshi, strengthening the case for federal oversight of prediction markets and dealing a setback to state-level enforcement efforts.

The United States Court of Appeals for the Third Circuit upheld a preliminary injunction blocking New Jersey from applying its gambling laws to Kalshi’s event-based contracts. 

The decision affirms that such products fall under the jurisdiction of the Commodity Futures Trading Commission [CFTC], not individual states.

The ruling marks one of the clearest judicial endorsements yet of the CFTC’s long-standing position that prediction markets operate as federally regulated derivatives.

Court affirms federal jurisdiction over event contracts

At the center of the case is how event contracts should be classified. The court agreed with Kalshi and federal regulators that these instruments qualify as derivatives—specifically “swaps”—under the Commodity Exchange Act.

That classification places them squarely within the CFTC’s authority, preempting state gambling laws. Judges warned that allowing states to regulate such products individually would create a fragmented system that would undermine the uniform market structure Congress intended.

The decision effectively limits states’ ability to treat federally regulated prediction markets as unlicensed betting platforms.

Ruling strengthens CFTC’s ongoing legal strategy

The outcome directly reinforces arguments made by the CFTC in its recent lawsuit against Illinois, where state regulators issued cease-and-desist orders against platforms including Kalshi and other crypto-linked prediction markets.

In that case, federal regulators argued that event contracts fall under derivatives law and should be governed at the national level. The Third Circuit’s decision now gives that position judicial backing, shifting the debate from theory to precedent.

Rather than a standalone win for one platform, the ruling strengthens the CFTC’s broader push to establish clear federal authority over the sector.

State-level crackdowns face new pressure

The decision could have immediate implications for other states attempting to regulate prediction markets under gambling frameworks.

Efforts like those seen in Illinois rely on the argument that event-based contracts resemble sports betting or wagering.

However, the court’s ruling signals that federally approved platforms operating as designated contract markets may be shielded from such actions.

This raises the stakes in ongoing legal disputes, as states may now face greater barriers to enforcing local restrictions against federally regulated platforms.

A step toward national scaling of prediction markets

Beyond the legal implications, the ruling addresses a key structural question: whether prediction markets can scale as a unified financial system in the U.S.

A fragmented, state-by-state approach would likely limit liquidity and participation. By contrast, federal preemption supports the development of a nationwide market, aligning prediction platforms more closely with traditional derivatives exchanges.

This could accelerate institutional interest and broader adoption, particularly as event contracts expand into areas such as macroeconomic indicators, elections, and sports-linked outcomes.

Final Summary

• The Third Circuit’s ruling in favor of Kalshi reinforces the CFTC’s claim that prediction markets fall under federal derivatives law, limiting state-level enforcement.
• The decision strengthens the legal foundation for nationwide scaling of prediction markets. However, debates over classification and oversight are likely to continue.
