The US Commodity Futures Trading Commission (CFTC) issued an interim final rule on 9 October 2026 that excludes casino-style gambling products from the legal definition of a "swap". In plain terms, casino games and sportsbook wagers stay under state gambling law, not federal derivatives law. The rule took effect on publication and is open for comment. It does not answer the bigger question of whether sports event contracts on prediction markets are swaps.
What the CFTC did
A swap, in US law, is a type of derivative contract the CFTC oversees. Prediction markets such as Kalshi list "event contracts" that pay out on a yes-or-no outcome, and argue these are federally regulated swaps.
According to CFTC Release 9309-26:
| Point | Detail |
|---|---|
| Type | Interim final rule (in force before comments close) |
| What it says | Casino-style gambling products are excluded from the swap definition |
| Examples named | Casino games and wagers on sportsbooks |
| Effective | On publication in the Federal Register (91 FR 65969) |
| Comments | Within 30 days of publication, via Regulations.gov |
Chairman Michael S. Selig said: "Casino-style gambling products are not derivatives." The CFTC describes the rule as codifying its longstanding position, and Selig said it "provides clarity regarding the limits of its regulatory remit."
What it leaves open
The release does not say whether a contract on the result of a sports game counts as gambling or as a swap. That is the issue in Flaherty v. KalshiEX (No. 26-299). In April 2026 a split Third Circuit panel held that Kalshi's sports event contracts are swaps and that federal law overrides New Jersey's sports betting laws, keeping an injunction in Kalshi's favour. New Jersey filed its petition asking the Supreme Court to hear the case on 2 September 2026.
On 7 October 2026, Ohio and 38 other states plus the District of Columbia filed a brief supporting New Jersey. They argue the federal courts are split and that the prediction markets' reading would strip states of their authority over gambling.
As of 22 October 2026, the Supreme Court docket shows Kalshi's response is due on 9 November 2026, after an extension, so the Court will not decide whether to take the case before then. More than ten amicus briefs have been filed, including from the American Gaming Association, the NFL and a group of 145 tribes.
Our interpretation: the rule confirms that casino games sit with the states, but it says nothing either way about sports event contracts. Until the Supreme Court decides whether to hear the case, that line remains contested.
What it means for players
As of October 2026, prediction markets are not licensed by state gambling regulators. If a dispute arises, you do not get a state regulator's complaint route, and state safer gambling tools such as self-exclusion lists may not apply. Licensed sportsbooks and online casinos remain regulated state by state; our guide to verifying a gambling licence explains how to check one.

Questions people ask
Are prediction markets like Kalshi legal sports betting?
That is the open question. Prediction markets say their sports event contracts are swaps regulated federally by the CFTC, so state betting laws do not apply. Many states say they are unlicensed sports betting. The Third Circuit sided with Kalshi against New Jersey, and New Jersey has asked the Supreme Court to hear the case (No. 26-299).
Does the CFTC rule affect sweepstakes casinos?
The CFTC release does not mention sweepstakes casinos. Our reading is that the rule changes little for them: sweepstakes sites have never been regulated as swaps, and states already handle them under gambling and sweepstakes law. Treat any claim that the rule bans or approves sweepstakes casinos with caution.
Why are states asking the Supreme Court to hear the Kalshi case?
In their October 2026 brief, Ohio and 38 other states plus the District of Columbia argue that federal courts are divided on whether the Commodity Exchange Act overrides state sports-gambling laws. They say the prediction markets' reading would strip states of long-held authority over gambling without clear words from Congress and weaken consumer protections.
What is the comment deadline for the CFTC rule?
The CFTC says written comments must reach it through Regulations.gov within 30 days of the rule's publication in the Federal Register (91 FR 65969). The CFTC's link points to the 19 October 2026 edition, which would put the deadline around 18 November 2026; check the docket for the exact date.
