What an Event Contract Actually Is

An event contract pays a fixed amount if a specific, defined outcome happens — a game result, an economic report, an election, a weather threshold — and pays nothing if it doesn’t. You buy and sell contracts on an exchange registered with the Commodity Futures Trading Commission (CFTC), called a Designated Contract Market (DCM), rather than placing a bet with a bookmaker.

That’s the structural difference from a sportsbook wager: a sportsbook sets odds and takes the other side of your bet directly, and it’s licensed by a state (or tribal) gaming regulator. An event contract trades on an exchange, where your counterparty is another trader, and the exchange itself is licensed federally. It also differs from a stock: a stock represents ownership in a company and trades on a securities exchange regulated by the SEC; an event contract’s payout is tied to a yes/no outcome, not a company’s earnings, and it trades on a derivatives exchange regulated by the CFTC.

The Question Everything Turns On: Swap or Wager?

The Commodity Exchange Act (CEA) defines a “swap” broadly to include an agreement whose value depends on the occurrence of an event with a financial, economic, or commercial consequence. If a sports-related event contract fits that definition, the CFTC argues it has exclusive jurisdiction over it — meaning states cannot apply their own gambling laws, under a legal doctrine called federal preemption.

If it doesn’t fit the definition — if it’s functionally a sports bet wearing an exchange’s clothing — then states argue their gambling laws apply as they always have, regardless of what federal regulator licenses the platform.

Courts have now answered this question three different ways. That’s the circuit split below.

Three Courts, Three Answers

A similar appeal involving Maryland is still pending before the Fourth Circuit, which heard oral argument in May 2026. Litigation is also ongoing in district courts covering Connecticut, Minnesota, New York, and Washington State, among others.

What the CFTC Did on October 9, 2026

On the same day, the CFTC issued two distinct actions.

The Interim Final Rule codifies that casino-style gambling products — including sportsbook wagers and casino games — are excluded from the legal definition of a swap. Chairman Michael Selig said: “Casino-style gambling products are not derivatives… the Commission today provides clarity regarding the limits of its regulatory remit.” This rule takes effect immediately upon publication in the Federal Register, with a 30-day comment window after that. It does not, on its own, say anything about whether sports event contracts are swaps — it only addresses traditional sportsbook-style gambling.

The Notice of Proposed Rulemaking (NPRM), titled “Further Definition of ‘Swap’ – Inclusions” (RIN 3038-AF82), proposes adding event contracts — including those based on sports, politics, cultural events, and weather — to the swap definition. Selig said these products are “commodity derivatives squarely within the CFTC’s regulatory remit under the Commodity Exchange Act and… within the agency’s exclusive jurisdiction.” This is a proposal only; it is not yet in effect. Written comments are due within 30 days of its Federal Register publication, submitted through Regulations.gov and referencing RIN 3038-AF82.

The NPRM states that at least seven CFTC-registered designated contract markets offered sports-related event contracts as of September 1, 2026.

These two actions followed an earlier Advance Notice of Proposed Rulemaking (ANPRM), published March 16, 2026, in which the CFTC sought public comment on how its existing rules should apply to prediction markets generally — including market-integrity safeguards, insider-trading concerns, and which event contracts might be prohibited as contrary to the public interest. That comment period closed April 30, 2026.

Sports vs. Everything Else

Almost every lawsuit and enforcement action described on this page is about sports-related event contracts. States have generally not gone after weather, economic, or political contracts with the same intensity — those categories don’t overlap with an existing, heavily regulated state industry the way sports betting does.

That could change. The CFTC’s pending NPRM would define “swap” to include event contracts based on politics, cultural events, and weather, not only sports. If finalized, it would strengthen the CFTC’s claim to exclusive jurisdiction over those categories too — but it’s a proposal, not a rule, as of the verification date, so treat sports contracts as the clearly contested category and everything else as comparatively, not definitively, settled.

Your State Right Now

This is a dated snapshot, not a legal determination. Use the tool above for a one-line version, or the table below (desktop) for more detail.

What a Court Order Can Do to Your Open Position

This is the question that matters most if you already have money on one of these platforms, and it’s the one none of the law-firm alerts or sportsbook roundups spend much time on.

When a state wins an injunction or passes a licensing law, the order is typically aimed at the platform — barring it from offering new contracts to residents of that state, or requiring it to geofence them out. What happens to a contract you already hold at that moment is a separate question, governed by the platform’s own terms of service, not by the court order itself. Massachusetts and Michigan have both produced orders restricting access going forward; reporting on both situations describes platforms continuing to operate for a period under stays or partial compliance rather than an instant, total shutdown, but the pattern is not uniform and has not been fully litigated state by state.

Because the legal question is unsettled, so is the practical one: whether an open contract would be voided and your premium refunded, settled early at the current market price, frozen until you can withdraw, or left to settle normally at its original expiration, likely depends on the specific order, the specific platform’s terms, and facts that haven’t yet been tested in court for most states on this list.

That’s why the honest answer is a set of questions to ask before you fund an account, not a reassurance. See the checklist below.

Taxes: Genuinely Unsettled

Event contracts could, in principle, be treated as financial contracts — similar to other instruments traded on a regulated exchange — or as wagering transactions, similar to a sports bet, depending on how the underlying legal question (swap or wager) ultimately resolves and how the IRS chooses to treat them. The two characterizations carry different rules for how gains, losses, and reporting work.

This article is not going to tell you that one of those treatments is correct, because no settled authority says so. Anyone presenting a confident, specific tax answer right now is getting ahead of the actual state of the law. Talk to a CPA familiar with derivatives and gambling tax treatment before you rely on any particular position, and check for IRS guidance that may have been issued after this page’s verification date.

What Protections Apply — and Which Don’t

Not SIPC. The Securities Investor Protection Corporation protects customers of failed securities brokerages, up to $500,000 including up to $250,000 in cash. Event contracts are derivatives, not securities, and these platforms are not broker-dealers, so SIPC does not apply.

CFTC segregation rules instead. A Designated Contract Market is required to hold customer funds in accounts segregated from its own operating capital, which is meant to protect customer funds from the firm’s creditors if the company fails. That is a different and narrower protection than deposit or brokerage insurance: there is no dollar cap and no dedicated insurance fund standing behind it the way SIPC or FDIC coverage works, and how an actual insolvency would play out in practice has not been tested.

Age. Federal commodity-market rules generally allow participation at 18. Several state-licensed sportsbooks, and most tribal gaming compacts, set the minimum age at 21. That gap has become a specific point of contention: court filings in Massachusetts and the tribal lawsuits in New Mexico both allege that these platforms allowed 18-, 19-, and 20-year-olds to trade sports contracts in jurisdictions where a licensed sportsbook could not legally have served them.

How This Likely Ends

A few things are in motion at once, each on its own timeline.

The Supreme Court. New Jersey filed a 332-page petition for a writ of certiorari on September 2, 2026, asking the Court to resolve whether federal law preempts state gambling laws as applied to CFTC-registered exchanges. The Court is not required to take the case; Kalshi’s response deadline was extended to November 9, 2026, after which the Court will decide whether to grant review. If it does, a definitive nationwide answer could still be a year or more away.

The CFTC’s rulemaking. Both the Interim Final Rule and the NPRM are open for public comment. The NPRM, in particular, could take months to finalize, and any final rule would itself likely be challenged in court by the states that have lost ground to it.

More circuits. The Fourth Circuit (Maryland) has not yet ruled, and district-court litigation is ongoing in several more states. Additional, possibly conflicting, appellate rulings are plausible before the Supreme Court, if it takes the case, resolves anything.

Until one of these resolves — and it’s reasonable to expect that could take through 2027 or beyond — the state-by-state patchwork described above is the operating reality.

Questions to Ask Before You Fund an Account

Copy this list before you deposit anything.

1. On cancellation: what do the terms say happens to open contracts if a court or regulator restricts the platform in my state? Are contracts voided and premiums returned, or settled?
2. On withdrawals: if access is blocked, how do I get my balance out, and how long does it take?
3. On custody: how are customer funds held? Is there any insurance, and what does it cover? It is not SIPC coverage.
4. On tax forms: which form will I receive, and when? Does the platform state a tax position? A form is not tax advice, and the treatment is disputed.
5. On records: export your transaction history regularly and keep it.
6. On yourself: am I hedging a real exposure, speculating with money I can lose, or chasing losses? If it’s the third, stop and call the National Problem Gambling Helpline at 1-800-522-4700.
