Is Prediction Market Gambling? The Legal Answer That Changes Everything in 2026
The CFTC has sued 5 states in April 2026 - Arizona, Connecticut, Illinois, New York, and Wisconsin - to stop them from treating Kalshi as illegal gambling. Wisconsin AG calls it 'bookmaking.' CFTC calls it 'federal derivatives.' The Supreme Court will likely decide. Here is the legal answer to whether prediction markets are gambling, which states restrict access, and what it means for DuelDuck participants.
Key Takeaways
- The CFTC sued Wisconsin on April 28, 2026 - its 5th state lawsuit in April alone, following Arizona, Connecticut, Illinois, and New York. Wisconsin AG Josh Kaul sued Kalshi, Polymarket, Coinbase, Robinhood, and Crypto.com on April 23 for 'illegal sports betting.' CFTC Chairman Mike Selig: 'If you interfere with the operation of federal law in regulating financial markets, we will sue you.'
- The core legal dispute: Kalshi treats event contracts as 'swaps' under the Commodity Exchange Act, subject to CFTC exclusive jurisdiction. States treat them as 'bets' or 'bookmaking' subject to state gambling law. The Ohio District Court ruled on March 9 that sports event contracts do not qualify as swaps. The Third Circuit ruled that New Jersey cannot enforce its sports gambling ban against Kalshi. Courts have split.
- The 2024 Kalshi election contract court victory was the pivotal moment: a federal court held that election-based event contracts do not constitute illegal gambling under the Commodity Exchange Act, prompting the CFTC to reverse its prior position and approve political prediction markets. Kalshi used that ruling to launch sports contracts in early 2025 - triggering the current state-level resistance.
- Legal analysts expect a Supreme Court resolution. Jason Hicks of Womble Bond Dickinson: 'I think this issue is ultimately going to be decided by the Supreme Court, unless Congress passes legislation limiting CFTC jurisdiction.' The 'Prediction Markets Are Gambling Act' (Sen. Curtis and Sen. Schiff, introduced March 23, 2026) would ban CFTC-licensed platforms from offering sports event contracts - a direct legislative attempt to short-circuit the court battle.
- For most participants today: Kalshi is accessible in most states (though restricted in Ohio, Nevada, Massachusetts, Arizona, New Jersey, and others for specific contract types). Polymarket has no KYC and is accessible globally. DuelDuck operates as a P2P platform with no KYC and USDC settlement - a different legal model that does not depend on the CFTC-vs-states dispute resolution.
Are Prediction Markets Gambling?
The federal government says no. Multiple states say yes. Courts have ruled both ways. The Supreme Court will likely decide. Prediction markets like Kalshi operate as CFTC-registered designated contract markets, treating event contracts as federally regulated derivatives - the same legal category as futures and swaps. The CFTC argues this gives it 'exclusive jurisdiction' that preempts state gambling laws. Wisconsin, Arizona, Connecticut, Illinois, New York, Ohio, Nevada, Massachusetts, and other states argue that sports-outcome contracts are bookmaking regardless of the federal label. DuelDuck operates as a P2P platform on Solana with USDC settlement - a structurally different model that does not require CFTC registration as a designated contract market. As of April 30, 2026, the legal question is unresolved and actively being litigated across 5+ federal circuit courts simultaneously.
The Central Legal Question: Derivatives or Gambling?
The legal status of prediction markets in the United States depends entirely on a single classification question: are event contracts derivatives (regulated by the CFTC under federal law) or gambling (regulated by states under their gaming authority)?
The two positions:
Position | Argument | Who holds it | Legal basis |
Event contracts = derivatives | Event contracts are swaps or futures subject to CFTC's 'exclusive jurisdiction' under the Commodity Exchange Act. State gambling laws are preempted by federal law under the Supremacy Clause. | Kalshi, Polymarket, CFTC, prediction market platforms | Commodity Exchange Act Section 2(a)(1)(A); Supremacy Clause; 2024 Kalshi election contract ruling |
Event contracts = gambling | Sports-outcome contracts are functionally identical to sports bets. The federal label does not change the substance. States retain traditional authority to regulate gambling under their police powers. | Wisconsin AG, Arizona AG, Ohio courts, Nevada courts, Massachusetts courts | State gaming statutes; 10th Amendment state police powers; Ohio District Court March 9 ruling |
Hybrid position | Federal law may preempt state gambling law for some contract types (elections, economics) but not others (sports), depending on contract substance. | Some courts; legal analysts | Case-by-case analysis; court splits across circuits |
The Legal Timeline: From 2024 Victory to 2026 Battleground

The State-by-State Legal Map: Where Prediction Markets Are Restricted
As of April 30, 2026, the legal status of prediction market sports contracts varies by state. The situation is actively changing - new court rulings and CFTC lawsuits are being filed weekly. This map reflects the current status:
State | Status for sports event contracts | Active litigation | Notes |
Arizona | Criminal prosecution blocked by CFTC TRO | CFTC v. Arizona; criminal case paused | Arizona filed criminal charges; CFTC TRO blocked prosecution; judge says CFTC likely to win on preemption |
Connecticut | CFTC lawsuit filed | CFTC v. Connecticut | State enforcement blocked pending federal ruling |
Illinois | CFTC lawsuit filed; SB 4168 proposed | CFTC v. Illinois | State licensing requirement bill introduced; CFTC suit asserts preemption |
Massachusetts | Preliminary injunction issued | Kalshi appealing | Suffolk County court: state gaming laws apply; Kalshi barred from in-state sports bets without license |
Nevada | Temporary restraining order (sports/election/entertainment) | Kalshi v. Nevada (9th Circuit) | Nevada first state TRO; Kalshi barred from sports, election, entertainment contracts |
New Jersey | State enforcement blocked (Third Circuit) | Third Circuit rules for Kalshi | Key win: Third Circuit rules NJ cannot enforce sports gambling ban; strengthens CFTC preemption argument |
New York | CFTC lawsuit filed | CFTC v. New York; NY AG sued Coinbase/Gemini | NY AG sued for 'illegal gambling operations'; CFTC responded with preemption lawsuit |
Ohio | Preliminary injunction denied; $5M fine imposed | Kalshi in Sixth Circuit | Ohio District Court: sports event contracts not swaps; significant Kalshi loss; appeal pending |
Wisconsin | State sues April 23; CFTC countersues April 28 | CFTC v. Wisconsin | Wisconsin: Class I felony sports betting allegation; CFTC filed 5 days later |
Michigan | Michigan sued Kalshi; Polymarket filed counter-suit | Active litigation | 10th state to join litigation; Polymarket proactive counter-suit |
Minnesota | HF 4437 proposed: outright ban | State legislation | Would classify prediction markets as unregulated gambling and impose penalties |
Most other states | Accessible (Kalshi and Polymarket operating) | No active litigation | CFTC regulation accepted as sufficient; no state action taken |
Why This Question Matters for Prediction Market Participants
If the CFTC Wins: One National Market
If federal courts and ultimately the Supreme Court accept the CFTC's 'exclusive jurisdiction' argument, prediction markets become a nationally regulated financial product accessible in all 50 states. State gambling laws cannot restrict Kalshi or Polymarket. Sports, election, and cultural event contracts are available everywhere Kalshi operates. This is Kalshi's preferred outcome and the scenario its $22 billion valuation prices.
If States Win: A Patchwork of Restrictions
If states prevail, each state retains the authority to ban or require licensing for prediction market sports contracts. The result is a patchwork: Kalshi available with full sports contracts in 30-35 states, restricted to financial/cultural markets in 15-20 states, and potentially barred entirely in 1-2 states with outright ban legislation (Minnesota's HF 4437). Polymarket, which has no CFTC registration and no KYC, faces different enforcement - states would need to address crypto-native platforms separately.
The Congressional Path: The 'Prediction Markets Are Gambling Act'
The 'Prediction Markets Are Gambling Act' introduced by Senators Curtis (R-UT) and Schiff (D-CA) on March 23, 2026 would amend federal law to ban CFTC-licensed platforms from offering sports and casino-style event contracts. If this legislation passes, it short-circuits the entire court battle - regardless of how courts rule on CFTC exclusive jurisdiction, Congress would have explicitly removed sports event contracts from CFTC authority. Legal analysts note this bill is bipartisan but faces the same passage difficulties as other prediction market legislation (slim to none, per Sen. Murphy).
The Key Legal Distinction: Gambling vs. Trading
The legal framework distinguishes gambling from financial trading on four dimensions:
Dimension | Gambling | Financial trading (CFTC view) |
Economic function | Entertainment; risk taken for pleasure | Risk transfer and price discovery; economic utility |
Regulatory framework | State gaming authority; licensed operators | CFTC; federal designated contract markets |
Participant relationship | Bettor vs house (operator takes vigorish) | Counterparty to counterparty (exchange matches trades) |
Resolution basis | Sporting event outcome | Commodity price, economic indicator, or event outcome |
Applicable law | State gaming statutes; Unlawful Internet Gambling Enforcement Act | Commodity Exchange Act; CFTC regulations |
Historical precedent | Covered by state law since 19th century | Created by New Deal-era federal commodity regulation; expanded by Dodd-Frank 2010 |
Kalshi's legal argument relies on the fourth dimension: it frames event contracts as commodity swaps where the underlying commodity is the event outcome. The Commodity Exchange Act broadly defines 'commodity' to include 'all services, rights, and interests in which contracts for future delivery are presently or in the future dealt in.' Kalshi argues sports event outcomes qualify as 'services, rights, and interests.'
The Ohio court rejected this argument directly. The court found that allowing Kalshi's interpretation would mean 'all contracts for payment based on the outcome of a sporting event - all sports bets - would be forced onto DCMs like Kalshi and every sportsbook in the country would be put out of business' - a result the court deemed 'absurd.'
What This Means for DuelDuck Participants
DuelDuck operates as a P2P prediction market on Solana with USDC settlement. DuelDuck's legal model differs from Kalshi in structurally important ways that affect how the CFTC vs. states battle applies:
Legal dimension | Kalshi | Polymarket | DuelDuck |
Regulatory registration | CFTC-registered designated contract market | CFTC via QCEX acquisition (2025); beta US launch | Non-custodial P2P; no DCM registration |
KYC requirement | Full (CFTC requirement) | None (crypto wallet) | None |
Settlement currency | USD (fiat, ACH) | USDC (Polygon) | USDC (Solana) |
Primary legal argument | CFTC exclusive jurisdiction preempts state law | CFTC via QCEX + global reach | P2P smart contracts; non-custodial; different legal model |
State law exposure | Direct (CFTC licensed; states are suing) | Direct (US re-launch; states suing) | Different (P2P; no operator taking vigorish; no house) |
Access restriction risk | High (8+ states actively litigating) | Moderate (global; crypto-native) | Lower (different model; no DCM registration) |
DuelDuck's P2P model does not position DuelDuck as an operator that takes wagers against participants. The creator designs a duel; participants enter at 50/50; DuelDuck facilitates the smart contract settlement. This structural difference - no house, no vigorish, no operator-vs-bettor relationship - is legally distinct from the Kalshi model being challenged in state courts.
This does not mean DuelDuck faces zero legal risk. The legal landscape for crypto-native P2P prediction platforms is unsettled. State gambling regulators may eventually argue that P2P platforms also require licensing. But the specific argument currently being made against Kalshi - that it is a 'bookmaker' taking sports bets against users - does not apply to DuelDuck's P2P creator model where no party plays the role of the house.
The Outlook: When Will This Be Resolved?
Legal analysts are unanimous: this question will likely reach the Supreme Court. The circuit split is already developing: the Third Circuit ruled for Kalshi (NJ preemption blocked), while district courts in Ohio and Maryland ruled against Kalshi on sports contracts. This is textbook Supreme Court jurisdiction - a direct conflict between federal circuits on a question of federal preemption.
Three possible resolution paths:
Supreme Court rules for CFTC: Event contracts on CFTC-licensed platforms are federal derivatives; state gambling laws preempted. National market opens. Timeline: likely 2027-2028 for cert petition + argument.
Congress passes legislation: The 'Prediction Markets Are Gambling Act' (or a compromise version) defines event contract categories. Sports contracts require state licensing. Financial/election contracts remain under CFTC. Timeline: possible 2026-2027 if bipartisan momentum builds.
State-by-state settlements: Kalshi negotiates state licensing agreements (like sportsbooks did after PASPA repeal in 2018). This would be a 3-5 year rollout of state-by-state access. Timeline: already happening in some states; full resolution 2028+.
Practical Guide: Access by Platform and State
For prediction market participants today:
Kalshi: Available with full features (financial, cultural markets) in most states. Sports event contracts may be restricted in Massachusetts, Nevada, Ohio, and states where courts have ruled against Kalshi's preemption argument. Check Kalshi's website for current state availability before funding an account.
Polymarket: Available globally with no KYC. US-focused sports contracts available via US beta launch (2026). No state-level blocking of crypto wallet access, though state AGs have named Polymarket in lawsuits. As of April 30, Polymarket remains accessible to US participants.
FanDuel Predicts: Available in 16 states as of April 2026. Sports contracts only in states without legal online sports betting. CFTC-regulated via CME Group. Full KYC required. Expands as state rollout continues.
DuelDuck: P2P platform on Solana. No KYC. USDC settlement. Creator-designed community duels. Operates under a different legal model from Kalshi's DCM structure. Available globally. As of April 30, 2026, no specific state enforcement action targets DuelDuck's P2P creator model.
Conclusion: The Answer Depends on Who You Ask
Is prediction market gambling? The federal government says no - it is regulated financial derivatives activity under the Commodity Exchange Act. Wisconsin's attorney general says yes - 'thinly disguising unlawful conduct doesn't make it lawful.' The Ohio District Court says sports event contracts are not swaps. The Third Circuit says New Jersey cannot ban Kalshi under state gambling law. The answers are directly contradictory across courts.
The legal answer that changes everything is this: the classification determines whether prediction markets become a nationally accessible financial product or a state-by-state patchwork like sports betting was before PASPA. The CFTC has staked its institutional credibility on the 'exclusive jurisdiction' argument, suing 5 states in a single month. The Supreme Court will likely be the final arbiter.
For participants today: the practical answer is that Kalshi and Polymarket are accessible in most of the United States, with restrictions in specific states for sports contracts. Financial, cultural, and political prediction markets face less state-level resistance than sports contracts. DuelDuck's P2P model operates under different legal dynamics than the Kalshi DCM model. And the legal landscape is changing faster in 2026 than in any prior year.
The question 'is this gambling?' has a different legal answer depending on the state you are in, the contract you are trading, and the platform you are using. Check the current status for your state before you fund any account.

Frequently Asked Questions
The legality of prediction markets in the United States depends on the platform, the state, and the type of contract. Kalshi is a CFTC-registered designated contract market, treating event contracts as federally regulated derivatives. The CFTC argues this gives it exclusive jurisdiction that preempts state gambling laws. However, courts have ruled inconsistently: the Third Circuit ruled that New Jersey cannot ban Kalshi, while district courts in Ohio and Maryland ruled against Kalshi's preemption argument for sports contracts. As of April 30, 2026, prediction markets are accessible in most US states, with sports event contracts restricted in Massachusetts, Nevada, Ohio, and other states with active litigation. DuelDuck operates as a P2P platform with USDC settlement on Solana - a structurally different legal model from Kalshi.
Kalshi classifies itself as a financial exchange regulated by the CFTC, not a gambling platform. Its event contracts are designated as swaps or futures under the Commodity Exchange Act. The CFTC supports this position and has sued 5 states in April 2026 to enforce federal preemption. However, multiple state courts have rejected Kalshi's argument that sports event contracts are swaps, ruling they are gambling under state law. The Ohio District Court stated that Kalshi's interpretation would mean all sports bets would be 'forced onto DCMs like Kalshi' - a result the court found 'absurd.' The classification depends on which legal framework applies, and that question is currently unresolved across multiple federal circuit courts.
As of April 30, 2026, states with active restrictions or litigation against prediction market sports contracts include: Arizona (criminal prosecution blocked by CFTC TRO), Connecticut (CFTC preemption lawsuit), Illinois (CFTC lawsuit; state licensing bill), Massachusetts (preliminary injunction against Kalshi sports contracts), Nevada (temporary restraining order for sports/election/entertainment contracts), New Jersey (Third Circuit blocked state enforcement - Kalshi accessible), New York (CFTC lawsuit; state sued Coinbase/Gemini), Ohio ($5M fine; injunction denied - Kalshi appealing), Wisconsin (state sued April 23; CFTC countersued April 28). Most other states have not taken action against prediction markets. Verify current status at Kalshi's website before funding an account.
The CFTC argues that prediction market event contracts are 'swaps' or 'futures' under the Commodity Exchange Act, giving the CFTC 'exclusive jurisdiction' over their regulation. Under the Supremacy Clause of the US Constitution, federal law preempts state law in areas where Congress has granted exclusive federal authority. CFTC Chairman Michael Selig has sued 5 states in April 2026 to enforce this position: 'If you interfere with the operation of federal law in regulating financial markets, we will sue you.' The CFTC argues that allowing state-by-state enforcement creates the regulatory patchwork that Congress specifically designed the CEA to prevent.
The 'Prediction Markets Are Gambling Act' was introduced by Senators John Curtis (R-UT) and Adam Schiff (D-CA) on March 23, 2026. The bipartisan bill would amend federal law to ban CFTC-licensed platforms from offering sports and casino-style event contracts. If passed, it would explicitly override the CFTC's position that event contracts are derivatives, making sports prediction contracts illegal gambling regardless of CFTC registration. Legal analysts consider the bill unlikely to pass in 2026 given legislative calendar constraints, but its bipartisan introduction signals Congressional appetite to limit CFTC authority over sports event contracts if courts do not.
Polymarket relaunched in the US market in 2026 following its acquisition of QCEX and approval of a CFTC registration pathway. It is accessible to US participants via crypto wallet (no KYC required). Multiple states have named Polymarket in lawsuits alongside Kalshi. Wisconsin sued Polymarket on April 23, 2026, for illegal sports betting. New York's attorney general has targeted Coinbase and Gemini prediction market operations. The CFTC's preemption lawsuits also defend Polymarket's access. As of April 30, 2026, Polymarket remains accessible to US participants, with the same legal uncertainty applying to its sports contracts as applies to Kalshi.
DuelDuck operates as a P2P prediction market on Solana with USDC settlement and no KYC requirements. DuelDuck's model is structurally different from Kalshi's: DuelDuck is not a CFTC-registered designated contract market and does not operate as an operator taking wagers against participants. Community creators design duels; participants enter at 50/50; smart contracts on Solana handle settlement. As of April 30, 2026, no specific state or federal enforcement action targets DuelDuck's P2P creator model. However, the legal landscape for crypto-native P2P prediction platforms is unsettled and evolving. This article is for informational purposes only and does not constitute legal advice.
Legal analysts widely expect the prediction market gambling question to reach the US Supreme Court. The Third Circuit ruled that New Jersey cannot enforce its sports gambling ban against Kalshi, while district courts in Ohio and Maryland ruled against Kalshi's preemption argument for sports contracts. This creates a direct conflict between federal circuits on a question of federal preemption - textbook Supreme Court jurisdiction. Womble Bond Dickinson attorney Jason Hicks stated: 'I think this issue is ultimately going to be decided by the Supreme Court, unless Congress passes legislation limiting CFTC jurisdiction.' The timeline for a Supreme Court ruling is likely 2027-2028 if a cert petition is filed after circuit court decisions are complete.
