U.S. CFTC moves to fold event contracts into swaps regulations as legal fight rages

What new rules and proposals has the CFTC issued about event contracts?

The CFTC has taken two related steps to strengthen its claim over prediction markets. An interim final rule defines which sports wagering activities are not swaps. It also keeps casino-style gambling outside the CFTC’s swap definition. A separate proposed rule would explicitly classify event contracts as swaps under existing federal regulation.

The proposed rule covers contracts traded on platforms such as Kalshi and Polymarket. It names contracts based on sports, politics, cultural events, and weather. The mechanism is legal classification: if a contract is a swap, the CFTC says it falls within federal oversight rather than state gambling regulation.

The interim final rule becomes immediate policy but remains open to public input. The proposed swap rule has a relatively brief 30-day comment period. The moves are designed to support Chairman Mike Selig’s position as several states challenge the agency in court, including before the Supreme Court.

What is an event contract, and how do platforms such as Kalshi and Polymarket use one?

An event contract is a contractual exchange connected to whether a specified event occurs or reaches a defined result. The article treats these contracts as possible swaps, meaning transactions that could fall under the CFTC’s federal authority. That classification is central to the dispute because states view some of the same activity as gambling.

Platforms such as Kalshi and Polymarket trade event contracts for users. The article gives examples based on sports, politics, cultural events, and weather. Their contracts are exchanged between parties on a platform, creating the prediction-market transactions at the center of the regulatory fight.

The CFTC’s proposed rule would place these contracts inside existing U.S. swaps regulation. Kalshi and similar companies support the CFTC’s claim to be their only regulatory watchdog. States object and say some sports contracts amount to illegal gambling operations. Courts have issued conflicting rulings, and the Supreme Court has been asked to resolve the issue.

How broad is the proposed rule—what kinds of events, such as sports, politics, culture, or weather, could it cover?

The CFTC’s proposed rule is broad because it covers event contracts based on several types of outcomes. The article specifically names sports, politics, cultural events, and weather-related events. The key issue is not only what the contract concerns, but whether it belongs within the legal category of swaps overseen by the CFTC.

For example, a platform such as Kalshi or Polymarket could routinely trade a contract connected to a sports result or a weather event. The proposed rule would fold those event contracts into existing U.S. regulation of swaps. That classification would place them within the CFTC’s claimed federal jurisdiction.

The rule is still only a proposal, unlike the agency’s interim final rule on which sports wagering is not a swap. It has a 30-day comment period. Its broad scope could become important in the lawsuits with states, which argue that some sports contracts are gambling rather than financial products.

Why do several states argue that these contracts are gambling under state law rather than financial products under the CFTC's authority?

Several states argue that contracts tied to sports outcomes are wagers, not financial products. Their position is that state gambling regulators should oversee this activity, especially when it resembles sports betting available through state or tribal casinos and sportsbooks. The states have accused some platforms of running illegal gambling operations.

The dispute turns on how the transaction is classified. The CFTC says event contracts fit the definition of swaps and therefore belong under its federal oversight. The states say that label cannot erase their authority over gambling. They have raised the issue in lawsuits and submitted their views to the Supreme Court.

The legal record is unsettled. One federal appellate decision opposed the states, while two federal appellate rulings supported them. The CFTC’s new rules are intended to strengthen its position, but a TD Cowen analyst wrote that whether the interim rule actually works remains a separate question.

What would happen to state and tribal oversight of sports betting if event contracts were treated as federally regulated swaps?

If event contracts were treated as federally regulated swaps, the CFTC would claim primary authority over them. That would leave state and tribal gambling regulators without control over contracts covered by the federal classification. The change matters because several states say they have authority over the sports betting occurring on these platforms.

The CFTC’s interim final rule tries to separate casino-style gambling from swaps. It defines sports wagering that is not a swap, while the related proposal says event contracts, including sports contracts, are swaps. This distinction is intended to prevent the CFTC’s position from making every wager at a state or tribal casino or sportsbook federally illegal.

The outcome is not settled. States are challenging the regulator in court, and the Supreme Court has been asked to resolve the issue. The CFTC has already begun implementing Chairman Selig’s approach, but the article notes that its legal effectiveness remains uncertain.

What is a swap, and why does classifying a transaction as one give the CFTC jurisdiction over it?

In the article, a swap is a contractual exchange between parties that falls within the CFTC’s federal jurisdiction. More generally, a swap is a financial contract in which parties exchange payments or exposures according to agreed terms. The classification matters because federal law assigns swaps to the CFTC’s regulatory framework.

The CFTC argues that event contracts traded on platforms such as Kalshi and Polymarket fit this category. Its proposed rule would explicitly fold contracts based on sports, politics, culture, and weather into existing swaps regulation. If accepted, the contracts would be treated as federally supervised transactions rather than state-regulated wagers.

That classification is being tested in court. States argue that some sports contracts are gambling and belong under their authority. The CFTC has issued an interim final rule and proposed another rule to reinforce its position. The Supreme Court has been asked to resolve the broader conflict between the federal and state interpretations.

How does the U.S. division of power between federal regulators and state governments determine whether an activity is treated as derivatives trading or gambling?

The United States divides regulatory authority between federal agencies and state governments. In this dispute, the CFTC claims federal authority over swaps, while states claim authority over gambling, including sports betting. The legal classification therefore determines which government level can regulate the activity.

The CFTC says event contracts are swaps, which places them within its federal oversight. States argue that contracts tied to sports outcomes are wagers and may be illegal gambling operations. The interim final rule tries to distinguish casino-style gambling from contracts the agency considers swaps, while the proposed rule explicitly includes event contracts in swaps regulation.

That division of power is now being tested through lawsuits and a Supreme Court request. One federal appellate decision opposed the states, while two supported them. The CFTC’s rules may help present its interpretation in court, but they do not yet settle whether state or federal authority ultimately prevails.
