The CFTC adopted two June 2026 measures that classify prediction markets as regulated swaps while excluding casino gambling from that same definition. The move reshapes the legal landscape for Kalshi and Polymarket, whose explosive growth has triggered lawsuits across multiple U.S. states.
🔑 In brief
- Proposed rule extends the “swap” definition to event contracts (sports, politics, weather, culture), with a 30-day public comment window.
- Interim final rule, effective immediately, excludes casino gaming products from the swap definition.
- Sector growth: from 5 new listings/year between 2006-2020 to roughly 1,600 in 2025, with over 85% of Kalshi volume on sports.
- Multi-jurisdiction legal battles across Ohio, Arizona, Nevada and North Carolina, with the U.S. Supreme Court likely to weigh in.
- Chair Selig withdraws a 2024 rule that would have banned political and sports contracts, and announces a joint CFTC-SEC interpretation.
A two-pronged move to fix the regulatory perimeter
The Friday in June 2026 will be remembered as a watershed date for U.S. prediction markets. The Commodity Futures Trading Commission published two texts simultaneously that draw, in opposite directions, the line between what falls under its authority and what does not.
The first text is a proposed rule open to public comment. It amends the definition of “swap” to expressly include event contracts — products whose settlement depends on the outcome of a sporting, electoral, cultural or weather event. The second text is an interim final rule, effective on publication, that codifies the agency’s traditional view: sports betting and casino gaming are not commodity derivatives and remain outside the Commodity Exchange Act.
Both texts open a 30-day comment window and formalize a strategy prepared earlier, as the proposals had been submitted to the White House for review the previous month.
“Casino gaming products are not derivatives.”
Michael Selig, CFTC Chair
Context: a legal war across multiple jurisdictions
The CFTC’s move is only legible against the backdrop of an open confrontation with several states. Over the past two years, attorneys general and gaming commissions have filed numerous actions against Kalshi and Polymarket, accusing them of running unlicensed gambling. The CFTC has responded with counter-suits to defend what it considers its exclusive turf.
One episode sharply raised the political pressure: a few hours before the capture of Venezuelan President Nicolás Maduro by U.S. forces, a trader reportedly bought a $32,000 event contract on Polymarket, walking away with an estimated $400,000 profit. The case reignited the debate over insider trading on these platforms.
Stephen Piepgrass, partner at Troutman Pepper Locke, told Corporate Compliance Insights that the episode leaves observers uncertain about the CFTC’s final position, noting that the agency itself has not yet resolved this difficult question.
A sector that moved from niche to major financial market in a few years
The growth numbers are staggering. According to the Congressional Research Service, the pace of new event-contract listings remained anecdotal for years before flipping sharply in 2021.
| Year | New event-contract listings | Source |
|---|---|---|
| 2006-2020 (avg./year) | 5 | Congressional Research Service |
| 2021 | 131 | Congressional Research Service |
| 2025 | ~1,600 | Congressional Research Service |
| 2030 (projected volume) | over $1 trillion | Industry analysts |
Today, more than 85% of Kalshi’s volume relates to sports contracts. Some analysts expect trading volume to exceed $1 trillion annually by 2030.
The state landscape: between taxation, licensing and injunction
U.S. states have responded in scattered fashion, producing a regulatory mosaic that is generating significant litigation.
- Ohio: the Casino Control Commission proposed a $5 million penalty against Kalshi in April 2026 for offering unlicensed sports wagering since January 2025. Kalshi is contesting the action in state court.
- Arizona: the attorney general filed criminal charges in March 2026 for illegal gambling operation and unlawful election betting. A federal court blocked the prosecution a few weeks later, citing federal preemption, after the CFTC intervened in favor of Kalshi.
- Nevada: a state judge issued injunctions in 2026 prohibiting Kalshi, and separately Polymarket, from offering sports, election and entertainment contracts to Nevada residents.
- North Carolina: a different path: a budget law signed in July 2026 imposes a 6% tax on operators’ net transaction-fee revenue from January 1, 2027, without requiring a state gaming license.
On top of this fragmentation, a coalition of state attorneys general filed a brief backing Massachusetts’ position: Kalshi’s sports contracts should fall under state gaming law.
A jurisdictional split that may now land at the Supreme Court
Courts have so far rendered contradictory decisions. A federal appeals court ruled in favor of a CFTC-registered exchange on preemption questions, while a state court and a separate federal district court sided with state gaming authorities. The resulting jurisdictional split — pitting the NFL and other parties against Kalshi — has attracted the attention of the Supreme Court. The very question the CFTC is now trying to settle by rulemaking could instead be decided by the justices.
Michael Selig, in his first public statements since his December 2025 swearing-in, also announced the withdrawal of two previous proposals: a 2024 rule that would have banned political and sports contracts, and a 2025 staff advisory warning registrants against listing sports-related contracts amid ongoing litigation. He said the existing framework had failed market participants.
The CFTC chair also ordered staff to reassess the agency’s participation in pending federal cases where jurisdiction is contested, asserting that the CFTC holds the expertise and responsibility to defend its exclusive jurisdiction over commodity derivatives.
Crypto: the CFTC doubles down on a market-friendly stance
The agency frames this clarification as part of a broader, market-friendly strategy covering both traditional operators and crypto companies. It recently issued a no-action letter allowing crypto apps to offer regulated derivatives products and advanced separate rules for crypto-asset markets.
Selig further announced cooperation with the SEC on a joint interpretation to draw sharper lines between options and swaps that fall under the commodity umbrella and those that fall under securities law. The stated goal: reduce the regulatory fragmentation that currently penalizes both innovators and investors.
Conclusion: an unstable balance ahead of a landmark decision
By explicitly classifying event contracts as swaps while excluding casino gaming, the CFTC is trying to regain control of a sector whose exponential growth threatens the existing regulatory architecture. The move is clever on paper: it reassures registered operators without conceding the “gambling” label, while depriving states of their main economic argument in some pending cases.
But the outcome will hinge largely on the Supreme Court. If the justices confirm federal preemption, Kalshi and Polymarket will enjoy a national runway; if they instead validate state authority, today’s fragmentation will turn into a market freeze. For Kalshi, Polymarket and their users, 2026-2027 looks decisive — at a moment when several analysts expect volume to multiply tenfold by the end of the decade.
