CFTC's Sportsbook Carve-Out Takes Effect on 19 October as the Clock Starts on Event Contracts

The Federal Register publishes the CFTC's two swap rules on Monday: the exclusion for licensed sportsbooks and casinos is in force that day, and the proposal to define event contracts as swaps opens for comment until 18 November. The rule text says the first changes no one's legal rights, and the second is not yet law.

• The Commodity Futures Trading Commission's (CFTC) interim final rule excluding "casino-style gambling products" from the definition of a swap appears in the Federal Register on Monday 19 October and is effective that day, under its DATES section
• The interim rule still takes comments until 18 November, the same deadline as the companion proposal to define event contracts "including those based on sports-, politics-, cultural-, and weather-related events" as swaps
• From Monday, the swap definition in 17 CFR 1.3 excludes sports wagers, casino games and other games of chance offered by state- or tribe-licensed operators and not traded on a multilateral market
• The CFTC says the exclusion "would not change the legal rights or obligations of market participants", the event-contract definition remains a proposal, and neither text displaces state law or any court ruling
• Both comment deadlines fall in the same 10 days as the next steps in the Supreme Court petitions: Kalshi's response to New Jersey is due on 9 November and Nevada's answers to Robinhood and Crypto.com on 13 and 16 November

The Rules Announced on 9 October Get Their Dates

Both documents were filed for public inspection on Friday 16 October and are dated as issued on 15 October. The interim final rule, "Further Definition of 'Swap' To Exclude Casino-Style Gambling Products" (FR Doc 2026-21376, RIN 3038-AF81), appears at 91 FR 65969; the proposed rule, "Further Definition of 'Swap'-Inclusions" (FR Doc 2026-21377, RIN 3038-AF82), at 91 FR 66022. Each records that Chairman Michael Selig voted in favour and no commissioner voted against. A comparison by iGaming Times of key passages with the texts the CFTC posted on 9 October found no substantive change.

The interim rule is headed "Interim final rule; request for comments", and the CFTC says it "may modify the Interim Final Rule if warranted". It asks whether the exclusion should cover providers other than state-regulated gaming companies and tribes, whether it is clear which products are "regulated as gaming or gambling", and whether there is a better way to separate swaps from gambling than its test of how a product trades. The proposal invites comment on "any aspect". Neither entry lists a docket number; comments go through Regulations.gov citing the RIN, or by post to the Commission's Secretary.

What Changes on Monday, and What Does Not

The new paragraph (7) of the swap definition in 17 CFR 1.3 excludes an agreement offered by a person licensed or authorised to offer gambling or accept wagers under state law, or tribal law under the Indian Gaming Regulatory Act, acting within that licence, and regulated as gambling there, if it "is not traded on a board of trade, an organized exchange, a swap execution facility, or any other market in which trades are executed multilaterally or subject to individual negotiation". Three categories are named: sports wagers accepted by a licensed sportsbook; wagers on casino table games, slot machines and other electronic gaming devices; and other games of chance, "such as bingo, pool wagering, lotteries, and raffles".

For licensed operators, the CFTC's own analysis says nothing operational changes. It "already treats casino-style gambling products as outside its jurisdiction", knows of none traded on CFTC-registered exchanges, and expects no new compliance costs. The second test also binds them: it "ensures that State and Tribal-regulated entities do not, in the future, begin offering products properly within the Commission's jurisdiction" except under federal rules.

Several things do not change. Event contracts are not yet defined as swaps: the inclusion, a new paragraph (2)(i)(G), needs a final rule after comments close. The interim rule says nothing in it implies a contract outside the exclusion "is necessarily a swap". Neither text contains a clause displacing state law. The proposal lists the state actions it wants to answer, including orders requiring Kalshi to geofence sports contracts in Michigan, Washington and Nevada, Arizona's criminal case and New York's suit, and notes a petition for rehearing en banc against the Ninth Circuit's ruling. Both rules say their classifications are for Commodity Exchange Act purposes only, leaving federal tax treatment to the Internal Revenue Code.

The Carve-Out Changes the Code More Than the Market

The CFTC concedes the rule imposes no obligations. Its value is as an exhibit. The Sixth Circuit worried that if Kalshi's sports contracts were swaps, so was "every sports wager placed in a casino, on an online sports book, or between two friends at a bar", and the Ninth Circuit raised the same point about Caesars Sportsbook; from Monday a binding regulation says otherwise for licensed operators. That answers the courts' reductio, not their holdings. The Sixth Circuit required an event "inherently associated" with economic consequences, a test the proposal answers with Knicks playoff revenue and Houston furniture promotions, not with anything in force.

The Good-Cause Finding Is the Part Most Open to Attack

The CFTC skipped prior notice and comment because, it argues, state actions threaten markets with "tens of billions of dollars of transactions", citing cases where interim rules filled a gap left by a court order. The gap here is a circuit split the Supreme Court is being asked to resolve, and an agency that says its rule changes nothing in law has a harder case that ordinary rulemaking would cause "serious or real harm". A state or tribe challenging the rule would not need to win on the meaning of swap. The open comment period softens that risk, which may be why the CFTC chose to run one.

November Puts Both Records Before the Same Readers

Kalshi must file its response to New Jersey's petition, Flaherty v. KalshiEX, No. 26-299, by 9 November, while both comment periods are still open, and Nevada answers Robinhood (No. 26-338) and Crypto.com (No. 26-344) on 13 and 16 November. Kalshi can cite a rule in force and a proposal pending; New Jersey and the 39 states and the District of Columbia backing it can reply that the definition that matters is only proposed. The record also holds the CFTC's own concession, in the proposal, that greater certainty "could be perceived as a safety signal by retail participants" and that some event-contract trading characteristics "can be associated with addictive potential", lines opponents are likely to quote back.

The CFTC has turned the line between sportsbooks and exchanges into regulation. Whether event contracts sit on its side of that line is still a proposal, and the Supreme Court may decide before the CFTC does.
