Why do sports contracts specifically trigger lawsuits when election contracts don't?

Because sports betting is already a licensed, taxed state industry in most of the US, giving state gaming regulators a direct financial and jurisdictional stake in stopping a competing, unlicensed product. Election and economic event contracts don't compete with any existing state-licensed product, so states have little practical reason to challenge them even though the same legal question — is this a derivative or a bet — applies equally to both.

What is the core legal question in every sports contract lawsuit?

Whether a contract that pays out based on a sports outcome is a 'swap' regulated exclusively by the CFTC under the Commodity Exchange Act, or a 'bet' regulated by state gambling law. Federal courts have reached different answers to this same question — the Third Circuit and a federal court in Arizona found it's a swap; the Southern District of New York and Ohio's federal court found state gambling law still applies.

Did Kalshi always offer sports contracts?

No. Kalshi built its business on election and economic event contracts starting in 2021 and did not list its first sports-related event contracts until January 24, 2025. Nearly every state cease-and-desist letter, lawsuit, or court order that followed targets that January 2025 product line specifically, not Kalshi's original election and economic contracts.

Do non-sports event contracts face any legal risk?

Much less. Minnesota's SF 4760 is the one prominent exception — its ban covers prediction markets generally, including political, weather, and pop-culture contracts. Nevada's restriction also extends beyond sports to election and entertainment contracts. But in the roughly 20 other contested states, the dispute is confined to sports contracts, and political or economic contracts continue trading without a comparable legal challenge.

Could this same fight eventually hit non-sports contracts too?

It's possible but not the current trend. Minnesota's general ban shows a state can target prediction markets broadly rather than just sports contracts, and if the CFTC loses its preemption argument decisively at the Supreme Court level, states could in theory extend enforcement to other contract types. As of mid-2026, though, nearly every active dispute is specifically about sports contracts, reflecting the existing sports-betting licensing regime rather than a broader anti-prediction-market position.

Sports Event Contracts: Why They're the Legal Flashpoint

Kalshi has offered election and economic event contracts since 2021 with almost no legal challenge. It listed its first sports contracts on January 24, 2025. Within six weeks, Nevada and New Jersey sent the first cease-and-desist letters, and the dispute has since spread to roughly 20 states. The legal question is identical for both contract types — is this a federally regulated derivative or a state-regulated bet — but only sports contracts have triggered a fight.

Why Sports Contracts Specifically, and Not Elections or Economics?

Sports contracts compete directly with an existing, licensed, taxed state industry — legal sportsbooks — in a way election and economic contracts simply don’t. That competitive overlap, not a different legal theory, is what’s driving nearly every lawsuit in this space.

Most US states legalized and now license sports betting following the Supreme Court’s 2018 Murphy v. NCAA decision, which struck down the federal ban on state sports wagering. States built licensing regimes, collect tax revenue from licensed sportsbooks, and have a direct fiscal and regulatory stake in preventing an unlicensed competitor from offering the functional equivalent of the same product. A contract that pays out based on who wins the Super Bowl looks, to a state gaming regulator, indistinguishable from a sportsbook bet on the same game — except no state licensing fee was paid and no state tax was collected.

Election and economic contracts have no equivalent competing industry. No state licenses “will the Fed cut rates” wagering, so no state regulator has a comparable financial or jurisdictional interest in shutting it down. This is why Kalshi’s original product line — Congressional Control Contracts and similar election markets — drew a CFTC challenge in 2024 but essentially no state action, while its 2025 sports expansion drew nearly every state dispute described on our state-by-state cease-and-desist map.

What Is the “Gaming vs. Derivatives” Question, in Plain Language?

The core legal question in every one of these cases is whether a contract that pays out based on a sports outcome is a “swap” — a financial derivative regulated exclusively by the CFTC — or a “bet,” regulated by state gambling law. The answer changes who gets to license, tax, and police the product.

A derivative (or swap) is a financial contract whose value derives from an underlying reference — a stock price, an interest rate, a commodity price, or, in this case, a sports outcome. Derivatives trading on a CFTC-registered Designated Contract Market (DCM) falls under federal jurisdiction: the CFTC licenses the exchange, sets its rules, and — critically for this fight — federal law can preempt conflicting state regulation of the same product.

A bet, by contrast, is understood in every US state as a wager on an uncertain outcome, licensed and taxed at the state level under gaming law, with no federal derivatives framework involved at all.

Kalshi and Polymarket’s argument is that their sports contracts are legitimately structured as CFTC-registered swaps — the same legal category as agricultural futures or interest-rate derivatives — and therefore fall under exclusive federal jurisdiction that displaces state gambling law. States argue the underlying economics are identical to a sportsbook wager regardless of the wrapper, and that Congress never intended the CFTC’s swaps authority to let a company bypass state gambling licensing simply by calling the same product a “contract” instead of a “bet.”

Federal courts have not agreed on an answer. The Third Circuit and a federal court in Arizona concluded these are federally regulated swaps, preempting state gambling enforcement. Ohio’s federal court and the Southern District of New York concluded the opposite — that state gambling law still applies regardless of the CFTC registration. See our circuit split explainer for how those specific rulings conflict.

	Derivatives framework	Gambling framework
Regulator	CFTC (federal)	State gaming commission / AG
Licensing	CFTC-registered DCM	State sports-betting license

States’ position	—	Sports contracts are functionally sports bets regardless of the CFTC wrapper

Why Did Kalshi Wait Until 2025 to Add Sports Contracts?

Kalshi spent its first several years establishing itself as an election and economics platform before entering the far larger, far more contested sports market — a sequencing choice that shaped exactly which legal fights it’s now in.

Kalshi’s earliest contracts, launched around 2021, covered outcomes like Federal Reserve decisions, inflation prints, and — most prominently — the 2024 election’s “Congressional Control Contracts.” That product line drew a CFTC dispute of its own (the CFTC initially tried to block the election contracts as illegal gaming; a DC district court sided with Kalshi in September 2024, and the DC Circuit let the contracts run through the election). But no state sued Kalshi over election contracts, because no state licenses or taxes election wagering the way it does sports wagering.

That changed on January 24, 2025, when Kalshi listed its first sports-related event contracts. Nevada and New Jersey issued the first sports-specific cease-and-desist letters roughly six weeks later, in March 2025 — the opening moves in what has become the defining legal fight of this industry. Robinhood entered the same sports contract space in August 2025, partnering with Kalshi to offer NFL and college football contracts inside its own app, extending the same legal exposure to a second major platform. The full regulatory timeline traces this sequence in more detail, month by month.

Does This Mean Non-Sports Contracts Are Safe?

Largely, yes, with two notable exceptions worth watching. Political, economic, and weather contracts have drawn far less state action than sports contracts specifically — but Minnesota’s ban and Nevada’s restriction both show that a broader challenge is possible, not merely theoretical.

Minnesota’s SF 4760 is the clearest counterexample to the “only sports contracts are at risk” pattern: its felony ban covers prediction markets generally, extending to election, weather, and pop-culture contracts alongside sports. Nevada’s court-ordered restriction similarly reaches beyond sports to cover election and entertainment contracts. See our dedicated Minnesota explainer for how that ban’s broader scope compares to the sports-specific fights everywhere else.

Outside those two states, though, the roughly 20 other state disputes tracked on our legal tracker confine themselves to sports contracts, and non-sports markets have continued trading without a comparable legal challenge. Whether that holds if the Supreme Court eventually resolves the swaps-vs-gambling question decisively against the platforms is an open question this article can’t answer — it would depend on the reasoning of whatever ruling gets there.

What This Means for Where You Trade

If you’re trying to gauge legal risk by contract type rather than by platform, sports contracts carry meaningfully more regulatory uncertainty right now than election or economic contracts do, in every state except Minnesota and Nevada. That’s a genuinely different risk profile depending on what you’re trading, not just where you’re trading from.

The core legal question is whether these contracts are CFTC-regulated derivatives (swaps) or state-regulated bets — federal courts have reached opposite answers to that same question.
Kalshi didn’t list sports contracts until January 24, 2025; nearly every state dispute traces back to that specific product launch, not its earlier election and economic contracts.
Minnesota and Nevada are the two exceptions where the legal fight extends beyond sports contracts to elections, weather, and entertainment.
