Are Sports Prediction Markets Legal? The State-by-State Map in 2026
Last updated: August 2026 · 10 min read
Sports prediction markets occupy an unusual legal position in 2026. Federally, they are regulated by the Commodity Futures Trading Commission and operate across all fifty states. At state level, seventeen jurisdictions are actively contesting whether they should be permitted at all — through lawsuits, cease-and-desist orders, criminal referrals and in one case a legislative ban.
The scale makes the question hard to ignore. Combined monthly global trading volume across these platforms reached roughly $50.6 billion in July 2026, and dollars traded on prediction markets have surpassed dollars wagered through traditional sportsbooks. This article maps where things actually stand, explains the legal argument underneath the dispute, and looks at what could resolve it. It is general information rather than legal advice.
Quick Answer
Sports prediction markets are federally legal and technically available in all fifty states, but seventeen states are actively challenging them. The dispute turns on whether federally regulated event contracts preempt state gaming law. Courts have so far leaned toward federal authority — the CFTC secured injunctions blocking state enforcement in several cases — but rulings are inconsistent and the question is unresolved. Availability in contested states can change at short notice.
The Legal Question Underneath
The entire dispute reduces to a single classification problem: is a sports event contract a regulated financial derivative, or is it a wager wearing different clothing?
Platforms argue the former. Event contracts are traded on federally designated markets under CFTC oversight, using the same statutory framework that governs other derivatives. On that reading, federal commodities law preempts state gaming statutes, and states have no authority to prohibit what a federal regulator has permitted.
States argue the latter. Their position is that a contract paying out on whether a team wins is functionally identical to a wager on the same outcome, and that allowing federal registration to override state gaming law would let any operator bypass carefully constructed state regimes — including tribal gaming compacts and licensed sportsbook frameworks.
Both arguments are serious. The distinction between a derivative and a wager has never been perfectly clean, and sports outcomes sit at the least comfortable point on that spectrum.

Where Access Is Unrestricted
Thirty-three states and the District of Columbia currently place no active restriction on sports prediction markets:
Unrestricted access
Alabama, Alaska, Arkansas, Colorado, Delaware, District of Columbia, Florida, Georgia, Hawaii, Idaho, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Mississippi, Missouri, Montana, Nebraska, New Hampshire, New Mexico, North Carolina, North Dakota, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Vermont, Virginia, West Virginia, Wyoming.
Notably, this group includes states with well-established legal sportsbook industries and states with none. The split does not map neatly onto existing gambling policy, which suggests enforcement decisions have depended more on individual attorneys general and tribal gaming interests than on any consistent regulatory philosophy.
Where It Is Contested
Seventeen states have taken enforcement action or entered litigation. The form varies considerably.
Contested states and current posture
- Arizona — pursuing criminal charges against Kalshi; the CFTC obtained a temporary restraining order.
- California — tribes have challenged the platforms under the Indian Gaming Regulatory Act.
- Connecticut — issued cease-and-desist letters; the CFTC countersued. Polymarket unavailable.
- Illinois — filed suit alleging the products constitute gambling.
- Maryland — contests preemption of state gaming law. Polymarket blocked.
- Massachusetts — a court blocked Kalshi from offering sports contracts.
- Michigan — a circuit court ordered a temporary shutdown of Kalshi operations.
- Minnesota — first state to enact a legislative ban, subsequently blocked by a federal judge.
- Nevada — a district court injunction blocked both platforms.
- New York — proposed the ORACLE Act; a class action has been filed.
- Ohio — the Casino Control Commission levied a $5 million fine against Kalshi.
- Rhode Island — the attorney general sued both Kalshi and Polymarket.
- Tennessee — alleges the platforms operate as unlicensed sportsbooks. Polymarket blocked.
- Texas — investigating with stated intent to shut operations down.
- Utah — the governor and attorney general have vowed to ban the platforms.
- Washington — state enforcement blocked the platforms; appeals ongoing.
- Wisconsin — the attorney general filed three lawsuits; the Ho-Chunk Nation also sued.
How Courts Have Ruled
The judicial record so far tilts toward federal authority without settling the matter.
The Ninth Circuit granted the CFTC injunctive relief covering the Arizona, Connecticut and Illinois actions, and a federal judge blocked Minnesota’s legislative ban on federal jurisdiction grounds. The CFTC has argued, successfully in several venues, that state enforcement interferes with its own statutory authority.
But the pattern is not uniform. A federal judge in Washington halted Kalshi’s operations after a state challenge, a Nevada district court issued injunctions against both platforms, and the Massachusetts Supreme Judicial Court appeared sceptical of the argument distinguishing sports contracts from sports wagering. Different courts are reaching different conclusions on materially similar facts, which typically indicates a question heading toward higher review.
What Could Resolve It
Possible paths
- Supreme Court review — a genuine circuit split on federal preemption is the classic route to definitive resolution, though timelines are long.
- Congressional clarification — legislation defining whether sports event contracts fall within commodities regulation would settle the question faster than litigation, but faces competing lobbying from established gaming interests.
- CFTC rulemaking — the agency could narrow or formalise which event contracts are permissible, potentially conceding sports while preserving other categories.
- Negotiated frameworks — state-by-state accommodation involving revenue sharing or tribal compacts, which would be slow and inconsistent but avoids an all-or-nothing outcome.
Regulatory attention is also broadening beyond the preemption question. A congressional investigation into trading conduct opened in 2026, examined in our analysis of insider trading on prediction markets, and the New York City Council has begun reviewing how these platforms advertise. Legality and conduct are increasingly being scrutinised together.

The current position is genuinely unstable. Sports prediction markets are federally permitted and nationally available, seventeen states are trying to stop them, and courts are splitting on whether those states have the authority to do so.
For anyone tracking the category, the practical implication is that availability in contested states should be treated as provisional rather than settled. The underlying classification question — derivative or wager — has been unresolved for as long as these products have existed, and 2026 has forced it toward an answer without yet producing one. Anyone with a specific legal question about their own jurisdiction should consult a qualified attorney rather than rely on a general summary.

Which states restrict sports prediction markets?
Arizona, California, Connecticut, Illinois, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New York, Ohio, Rhode Island, Tennessee, Texas, Utah, Washington and Wisconsin have all taken enforcement action or entered litigation. The status in each varies and is actively changing.
What is the legal argument between the CFTC and the states?
Platforms and the CFTC argue that sports event contracts are federally regulated derivatives, so federal commodities law preempts state gaming statutes. States argue the contracts are functionally wagers and that allowing federal registration to override state gaming law would bypass licensed sportsbook regimes and tribal compacts.
How large are sports prediction markets in 2026?
Combined monthly global trading volume reached approximately $50.6 billion in July 2026, and dollars traded on prediction markets have surpassed dollars wagered through traditional sportsbooks.
How might this dispute be resolved?
Likely paths include Supreme Court review of the preemption question, congressional legislation defining whether sports event contracts fall under commodities regulation, CFTC rulemaking narrowing permissible contract types, or negotiated state-level frameworks. None has a clear timeline.
