Key Takeaways: Sports Event Contracts in 2026
Courts are split: district courts in Nevada, Maryland, and Ohio ruled the contracts are not swaps, while the Third Circuit — the first federal appeals court to weigh in, ruled on April 6, 2026 that they are, teeing up likely Supreme Court review.
On April 6th 2026, the Third Circuit ruled in favor of Kalshi as one of the biggest prediction markets in the US, stating that the platform’s sports event contracts qualify as swaps under the Commodity Exchange Act (CEA).
The CFTC sued Arizona, Connecticut, and Illinois directly on April 2, 2026, to defend its jurisdiction over event contracts.
Back in October 2025 and January 2026, Nevada and Massachusetts sided with state gaming regulators against Kalshi.
State availability varies based on ever-changing laws and regulations, so it’s crucial to check the latest rulings and legal status updates before placing your prediction.
Market participants have priced the chance of the Supreme Court reviewing the legal status of prediction markets before the end of 2026 at 64% (per market-based legal forecasts reported by Holland & Knight and PlayUSA in April 2026).
What Are Sports Event Contracts?
Today prediction markets are like online sportsbooks in the sense that they allow bettors to wager on a specific outcome. Only this time, instead of betting against the house and at specific odds, prediction markets allow you to trade event contracts. It boils down to binary options, as you can bet either that a certain event will unfold or not.
Unlike traditional futures, which are tied to the prices of physical goods like oil or grain, these event contracts are priced strictly according to the perceived likelihood of specific events occurring. The event can be anything: from the closing price of Bitcoin to political elections and sports outcomes.
The biggest difference compared to traditional bookies is the way bets work. Instead of betting against the house, market participants can buy and sell contracts amongst each other. For instance, if you’re betting on a specific team to win a basketball game, someone else has to back the opposite contract for the trade to even occur.
The rules are simple
Winning contracts are valued at $1 per contract, while losing ones yield $0. Back in 2025, Kalshi became the leading platform for sports event contracts in the US, thanks to the official approval by the CFTC, which regulates trading platforms.
The Legal Battle: CFTC vs State Regulators
The legal fight revolving around prediction markets has been cooking up in the States for quite a while now. On one side, we’ve got organizations like the CFTC, which regulate exchanges and platforms offering futures contracts trading and swaps.
The Core Legal Question
For a while now, prediction markets were considered regular financial trading platforms, but that’s when state-specific regulators stirred things up a bit. Many of them find that CFTC regulation isn’t suitable for platforms like Kalshi or Polymarket, as they effectively mask sports betting markets and offer them in other forms to avoid being bound by online betting regulatory oversight.
Important Distinction: Do not confuse “financial” event contracts with the actual operational sports contracts used to run an event—such as agreements defining ticket revenue splits, broadcasting rights, athlete anti-doping compliance, and liability insurance. State regulators care about the former because they look like gambling.
The CFTC and Kalshi claim these prediction contracts qualify as swaps, derivative financial contracts where two sides agree on cash distribution based on an outcome. However, Federal Courts in many states tend to disagree. More than 34 states have filed amicus briefs across various cases asserting states’ rights to regulate sports gambling (Holland & Knight, April 2026), with that coalition growing to 38–40 states in later filings.
This tension traces back to the 2018 repeal of the Professional and Amateur Sports Protection Act (PASPA), which allowed individual states to legalize sports betting. Because states adopted widely varying regulations—some allowing full mobile betting and others restricting it to in-person facilities—prediction markets represent a major jurisdictional clash between federal financial oversight and state-by-state gambling laws.
What Has Actually Happened in 2026
Up until early this year, sports event contracts were viewed in the same way as commodity futures trading options. That all changed when Arizona filed criminal charges against Kalshi, accusing it of obfuscating what seemed to be online betting options.
That leads us to the first big date in this legal battle: April 2nd, 2026. It’s when the CFTC filed federal lawsuits against the states of Arizona, Connecticut, and Illinois. April 6th, 2026, brought Kalshi and the CFTC the first major victory, with the Third Circuit Court of Appeals ruling in their favor.While this temporary ruling meant sports event contracts were viewed as swaps for the time being, it was not a final merits determination.
Because Federal Courts in Nevada, Maryland, and Ohio had previously reached the opposite conclusion, a split in the judiciary makes it highly expected for the Supreme Court to chime in on the matter.
Why This Genuinely Matters for Traders & Prediction Markets
Whether event contracts are considered gambling or swap trading, one thing is certain: their functionality remains unaffected. At their core, these platforms are simply exchanges that offer a chance of speculation on sports events.
Still, correct legal categorization is important as it greatly affects prediction market taxes and other regulatory obligations. On top of that, we’d be swimming in murky waters if we were to tell you the exact legal rulings for each state at this moment. Things change by the day, and regulatory matters like state-specific licensing might lead to a prediction market that functioned with no issue so far to close before the sun is up.
Where Sports Event Contracts Are Currently Available
We’re presenting the list of states where the rulings are clear so far to give you context. Do your due diligence before joining a prediction market from any of these states:
| State/Jurisdiction | Current Status | Basis |
|---|---|---|
| New Jersey | Operating under preliminary injunction — state cannot currently enforce gambling law against Kalshi | Third Circuit ruling, April 2026 |
| Nevada | Sports contracts are blocked based on a court-ordered ban | 2025 District Court ruling, currently awaiting decision based on an April 16th appeal |
| Massachusetts | Complete restriction | Suffolk County Superior Court injunction from January 2026 |
| Tennessee | Legal grey area, except for platforms like Kalshi, which are protected by the Federal Court rulings | Federal Court decision currently under appeal |
| Arizona | Previously banned, currently contested after the CFTC countersuit | CFTC-DOJ suit filed on April 2nd 2026 |
| Connecticut | Contested, cease-and-desist issued | CFTC-DOJ suit filed on April 2nd 2026 |
| Illinois | Contested, included in the CFTC suit, injunction preventing state-based legal action | CFTC-DOJ suit filed on April 2nd 2026 |
Status as of September 2026
Availability can also vary by sport. For example NBA event contracts remain broadly accessible outside the states with active bans or injunctions listed above, while NFL event contracts, which see the highest trading volume, tend to draw the most regulatory scrutiny in contested states like Massachusetts and Nevada.
Sports Event Contracts vs Traditional Sports Betting
Both classic sports betting and sports event contract trading allow bettors to place predictions on an underlying event, but the underlying mechanisms differ wildly.
| Feature | Sports Event Contracts | Traditional Sports Betting |
|---|---|---|
| Counterparty | Trader vs other traders on an exchange | Bettor vs the sportsbook directly |
| Regulatory body | CFTC as a federal derivatives regulator | State-specific commissions |
| Licensing details | Federal CFTC-issued license | State-specific license in the state where the site operates |
| How platform profits work | Profits earned based on transaction fees and trades | Profits earned based on the margin built into the odds |
| Availability | Depends on the litigation | Consistently available throughout any state with legalized sports betting |
Risks Created by the Legal Uncertainty
At Tradeblock, our experts deal with the economic indicators and risks associated with different types of trading, but sports contract predictions present unique structural risks:
Sudden state-level access loss
Shifts in local regulations could change overnight, leaving your financial positions open or frozen before a contract can settle.
Inconsistent access across states
Regulated sportsbooks feature clear state-by-state licensing. Event contracts are subject to localized court injunctions that limit accessibility unevenly.
Platform-specific exposure
Litigation often targets specific platforms (like Arizona vs. Kalshi) rather than the asset class as a whole, meaning a ruling against one exchange may not immediately apply to another.
Reversal risk on appeal
Though the April 2026 ruling of the Third Circuit favored prediction markets, it was an interim injunction. Reversals upon full merit reviews or Supreme Court intervention remain a very real possibility.
Conclusion
Hopefully, this guide clears things up for you when it comes to the prediction markets vs sports betting matter. Both allow bettors/traders to wager on outcomes of future events, but the real question still remains open: should exchange-based financial instruments fall under the same regulations as online betting?
For now, it seems that only time will tell. We’ve merely scratched the surface in this guide based on the rulings and cases closed or in process halfway through 2026.
If you’re planning on trading sports event contracts, the best piece of advice Tradeblock experts could give you is to check the latest regulations in your jurisdiction, as well as platform-specific considerations, before you open a position.
FAQs
Are sports event contracts legal?
Sports event contracts are regulated under federal commodities law, but their legal status varies from state to state. Currently, they are treated as trading contract payouts in some jurisdictions and prohibited as unauthorized gambling in others.
What is the difference between a sports event contract and a sports bet?
Sports event contracts and online bets both require you to manage risk and predict a sports event outcome. Still, they’re processed in different ways, as online bets are placed against the house with the house edge reflected in the odds, while sports event contracts are exchanged between traders.
Why is there an argument between Kalshi and state governments over trade event contracts?
States like Arizona and Connecticut argue that these options are simply online sports betting masked as financial products to bypass state regulatory oversight. The CFTC has counter-sued, arguing that federal law over commodities and swaps preempts state gambling rules.
Can sports event contract access change without warning?
Yes, sports event contract access could change without warning depending on the latest state regulations and outcomes of pending court cases currently unfolding in the US.
Will the Supreme Court decide whether sports contracts are legal?
While there’s no guaranteed answer, chances are that the Supreme Court will take matters into its own hands. What’s more, sports event contract traders already predict this with a 64% chance of it coming into fruition.
