Nevada Prediction Markets: How the Casino Capital Went to War With Event Contracts

No. As things stand on August 2, 2026, sports, election and entertainment event contracts cannot be offered lawfully to Nevada residents. Two Carson City preliminary injunctions bar the two operators that fought to stay — Kalshi and Polymarket US — from listing those categories in the state, the other major platforms pulled out voluntarily or under enforcement pressure, and the federal preemption question that could reopen the market is still sitting undecided at the Ninth Circuit. Nevada is not an open market with a few asterisks. It is a closed, actively litigated one where the state has won every round on the ground.

The narrow legal reason matters. Nevada has not “banned prediction markets” by statute the way Minnesota tried to; instead it argued in court that these particular contracts are unlicensed wagering under the state’s existing gaming law, and judges agreed enough to issue injunctions. That distinction is why availability could snap back if a higher court decides the federal Commodity Exchange Act displaces state gaming authority here. Until that happens, the practical answer for a Nevada resident is simple: the sports, election and event-outcome contracts you may have seen advertised are off the table in this state, and the platform most people associate with them has agreed to wall Nevada off completely.

Understanding Nevada’s ferocity starts with its books. Licensed gaming is not one industry among many here; it underwrites the state budget in the absence of an income tax, and every operator on the Strip and beyond pays for the privilege through a tightly policed licensing regime. A national platform routing sports contracts into Nevada phones without a state license, without paying Nevada’s gaming tax, and without touching the Board’s oversight machinery reads, from Carson City, as a free rider on a system everyone else pays into.

The Board also had numbers to point at. Nevada’s handle for the 2026 Super Bowl fell to a 10-year low, and state officials named prediction markets as one of the forces pulling volume out of the licensed sportsbooks. Whether event contracts caused the whole drop is arguable, but the figure gave the GCB a concrete grievance rather than an abstract turf claim: money that would have flowed through taxed, regulated books was moving instead through exchanges the state could not touch.

That framing explains why Nevada moved first and moved against everyone. The GCB opened the national enforcement wave with its Kalshi cease-and-desist in March 2025, months ahead of the crowd of states that later piled in, and it is the only regulator that has taken formal action against the entire top tier of operators — Kalshi, Polymarket, Coinbase, Crypto.com and Robinhood. Other states picked targets. Nevada went after the field.

Strip away the procedural noise and one question drives all of it: when a Nevada resident buys a “yes” on a football result on a federally registered exchange, is that a regulated financial instrument Washington controls, or a sports bet Nevada controls? Kalshi and its peers say these are event contracts — a species of swap — listed on a designated contract market under the CFTC’s exclusive authority, which would leave state gaming law with nothing to say. Nevada says the wrapper does not change the substance: a wager on a game is a wager on a game, and the Board licenses those.

Courts around the country have landed on opposite sides of that line, and Nevada’s own corner of the map is split against itself. When Kalshi litigated in federal district court here, the judge sided with the state’s reading that these sports contracts are not swaps — the mirror image of the Third Circuit’s April 2026 decision out of New Jersey, which found they were and that federal law preempted the state. That contradiction is precisely the fault line the Ninth Circuit is now weighing. The GCB’s most effective move was factual rather than doctrinal: it convinced a Nevada judge that Kalshi’s sports contract wording is, functionally, “indistinguishable” from a ticket written at a licensed Nevada book. Once a court accepts that, the financial-instrument label starts to look like a formality.

After the Board’s March 2025 cease-and-desist, Kalshi did what it does in most states — it sued in federal court, arguing CFTC preemption, and asked for an order shielding it from Nevada enforcement. It briefly succeeded: an early preliminary injunction kept the Board at bay. The reprieve did not last. In November 2025, U.S. District Judge Andrew Gordon dissolved that injunction, stripping Kalshi of its federal-court protection and clearing the way for Nevada to press its case through its own courts. That reversal is the hinge of the whole story — it is the moment the fight moved from a forum sympathetic to federal-instrument arguments into the state system, where Nevada’s gaming law is home turf.

The federal thread did not vanish; it fed upward into the consolidated appeal now pending at the Ninth Circuit, discussed below. But the day-to-day battle over whether Nevadans could actually reach these contracts shifted to Carson City, and that is where Nevada started winning decisively.

In the First Judicial District Court in Carson City, Judge Jason Woodbury became the central figure. He granted the GCB a temporary restraining order against Kalshi on March 20, 2026, extended it by two weeks in early April as briefing continued, and on May 18, 2026 entered a full preliminary injunction barring Kalshi from offering or facilitating any sports-, election- or entertainment-related contract within Nevada for the duration of the case. The injunction did not merely disapprove of the products; it made continued access to them in Nevada a violation of a standing court order, which is what set up everything that followed.

Kalshi tried to climb over the state courts. It sought an emergency stay of Woodbury’s order from the Nevada Supreme Court, arguing the federal preemption question should freeze state enforcement while the appeals played out. In late June 2026 the state high court declined, leaving the preliminary injunction fully in force. With that denial, Kalshi had lost at the trial level, lost its bid to pause the loss, and was left facing a court order it was not, in practice, fully honoring.

Here is where Nevada separates from every other state. Kalshi’s own IP-based geoblocking did not hold. GCB investigators reported buying prohibited contracts on the platform on eight separate occasions across four days — May 28, May 30, May 31 and June 1, 2026 — while physically inside Nevada. Those buys were not a technicality; they were direct evidence that a company under a court order was still taking Nevada action. The Board asked Judge Woodbury to hold Kalshi in contempt of the injunction and lined up an evidentiary hearing, with a show-cause hearing to follow.

Rather than defend a contempt case it was likely to lose, Kalshi settled the enforcement piece. On July 23, 2026 the parties filed a joint stipulation: Kalshi agreed to deploy a multi-source geofencing solution from GeoComply — the same vendor licensed sportsbooks use to police their own borders — designed to stop anyone inside Nevada’s geographic boundaries from trading the barred contracts, and to reach full compliance by August 12, 2026. Miss that date and the price is $120,000 per day until it complies. The stipulation includes a safety valve: Kalshi may submit a sworn affidavit explaining any delay in lieu of automatically owing the daily penalty, and it agreed to give Nevada the same rollout updates it has been providing to Michigan regulators and to let the Board’s people talk directly with GeoComply and Kalshi’s counsel about the technical fix. The contempt hearing was vacated. GCB Chair Mike Dreitzer framed the deal as ensuring Kalshi “fully complies with Nevada law moving forward or it will face stiff penalties.” No other state currently holds an active, court-enforced geofencing mandate against Kalshi with a hard money clock attached.

The practical upshot for a resident: whatever leakage let a Nevada address reach a Kalshi sports contract this spring is being sealed under court supervision, with real money riding on the seal holding by mid-August.

Kalshi was not the only operator Nevada dragged into Carson City. On January 16, 2026 the GCB filed a civil enforcement action against Blockratize Inc. and QCX LLC, the entities doing business as Polymarket US, asking the same court to declare the operation unlicensed wagering and shut it down in the state. Judge Woodbury granted a preliminary injunction against Polymarket US on May 29, 2026, ordering it to cease Nevada operations until the case resolves — a near-twin of the Kalshi order, eleven days later. Polymarket’s Nevada posture is worth separating from its national one: the company confirmed a formal US reentry in July 2026 after acquiring a CFTC-regulated exchange, but that domestic relaunch does not lift a Nevada court order, so residents remain walled off here regardless of the broader comeback. See our Polymarket review for how the platform operates where it is available.

Nevada has frozen out every major platform, but not by the same mechanism, and the difference is the reason Kalshi alone faced contempt. Crypto.com, which reaches customers through North American Derivatives Exchange Inc. (Nadex), and Robinhood, through Robinhood Derivatives LLC, both chose to stop offering sports event contracts to Nevada residents while the appeal is pending. Because they pulled the products voluntarily, there was no order for them to violate and no contempt exposure. Coinbase, distributing through Coinbase Financial Markets, likewise exited or restricted Nevada access. Kalshi is the one that kept going, ran into a court order, saw its blocking fail, and ended up under the geofencing settlement. Polymarket, meanwhile, was ordered out through its own injunction rather than leaving on its own.

Sort it cleanly and the map looks like this: Kalshi and Polymarket US are court-blocked by injunction; Crypto.com, Robinhood and Coinbase are out by choice or under enforcement pressure short of an injunction. The endpoint is the same for a resident — none of them are lawfully serving Nevada sports, election or entertainment contracts as of August 2, 2026 — but the legal exposure of each operator differs sharply.

None of the major platforms are lawfully offering sports, election or entertainment event contracts to Nevada residents on August 2, 2026, so this is not a page that ranks the best places to trade — there is no lawful place to trade those categories in this state. Because Nevada is blocked and actively litigating, we are not going to steer you toward operators you cannot legally use here; the honest service is telling you where each one stands. If the Ninth Circuit reverses course, some of these could return quickly, so the status here can change faster than most.

For the national landscape and the operators we review in states where they do run, see our prediction markets hub, and for the wider legal backdrop, our overview of whether online gambling is legal across the country.

It helps to know what the injunctions actually cover. A prediction market is an exchange, not a sportsbook. Instead of betting against a house that sets the line and profits on the margin, you buy and sell yes-or-no contracts against other traders, with each contract priced somewhere between one cent and 99 cents depending on how likely the crowd thinks the outcome is. Buy a “yes” at 60 cents and you collect a dollar if the event happens, nothing if it does not; the price itself reads as an implied probability. The platform matches orders and takes a small fee rather than booking the risk. Settlement is automatic when the real-world outcome is known.

That order-book structure is exactly what platforms lean on to argue they are running a financial market rather than a book, and it is exactly what Nevada judges have waved away for sports outcomes. The injunctions here reach three named categories — sports, elections and entertainment — which is where the resemblance to a Nevada sportsbook ticket is strongest. Contracts on things like macroeconomic data or weather sit further from Nevada’s gaming definitions and are not the focus of these orders, but as a practical matter the platforms carrying the barred categories have geofenced Nevada broadly rather than surgically, so a resident’s access to the whole product tends to go dark at once. The category that mattered most in court was sports, because sports is where Kalshi does the overwhelming bulk of its volume and where the “indistinguishable from a bet” argument lands cleanest.

The irony threaded through this whole fight is that the thing prediction markets most resemble — a sports wager — is already legal in Nevada, just through a different door. The lawful way to bet a game here is the licensed, regulated sportsbook, which is the exact system the GCB spent two years defending. Retail books operate across the state’s casinos, and mobile sports betting is available too, though Nevada keeps a wrinkle other states dropped years ago: mobile registration still generally requires an in-person visit to a licensed property to set up the account. That friction is part of why some Nevadans found app-based event contracts appealing in the first place, and part of why the Board treated them as a leak in the dam.

The differences a resident should weigh are real. For how licensed betting works in the state and which apps are live, see our guide to Nevada online sportsbooks, the broader roster of states with online sportsbooks, and our main online sportsbooks hub.

Part of Nevada’s objection is not about turf at all but about what falls away when a bet leaves the licensed system. A CFTC-regulated exchange sits outside the state’s consumer machinery entirely: there is no Nevada self-exclusion registry covering it, no GCB complaint process a trader can invoke, no state-supervised dispute resolution if something goes wrong, and typically an 18-year-old minimum where a licensed Nevada sportsbook requires 21. For the Board, those gaps are not incidental; they are the argument. A resident who runs into trouble on a licensed book has a regulator to call. A resident on an exchange has federal registration and a customer-service queue.

Taxes add another unsettled layer. Kalshi and most event-contract platforms do not issue the 1099-B forms a stockbroker would, and the IRS has published no clean classification telling traders whether gains are gambling income, capital gains, or something under the Section 1256 rules for regulated futures. Reporting can differ from one platform to the next depending on whether a contract is exchange-native or distributed through a brokerage. None of this is tax advice, and any Nevada resident with real trading gains from a period when access was open should treat the reporting question as genuinely open and get professional guidance rather than assume.

Worth noting on funds: when states have forced platforms out, operators have generally let customers close open positions and withdraw balances rather than trapping money, and some orders have required it. But that has been operator practice and court direction, not a guarantee written into any Nevada consumer statute. The protection a licensed book carries by law, an exchange carries by goodwill.

Nevada’s state-court wins settle who can trade here today, but the case that could reset the board is federal. A consolidated appeal at the U.S. Court of Appeals for the Ninth Circuit pulls together Nevada’s disputes with Kalshi, Robinhood Derivatives and Crypto.com’s Nadex into one proceeding on the core preemption question. A panel of Judges Ryan D. Nelson, Bridget S. Bade and Kenneth K. Lee heard nearly 150 minutes of argument on April 16, 2026, and the tenor was rough on the platforms — one judge dismissed the peer-to-peer-versus-bookmaking distinction as “sophistry to the nth degree.” On May 22, 2026 the same panel refused to stay Nevada’s and Washington’s enforcement while it deliberates, another signal that read as unfavorable to the operators. As of August 2, 2026, no decision has come down.

The reason to watch this specific court is national. The Third Circuit already ruled the other way for New Jersey in April 2026, finding the contracts are swaps and that federal law preempts state gambling law. If the Ninth Circuit rules for Nevada, two federal appeals courts will be in open conflict on the same question — the classic setup for the U.S. Supreme Court to step in — and legal observers have projected a cert petition, a likely grant, and a decision reaching into 2027. A ruling the other way, for the platforms, would undercut Nevada’s whole state-court campaign and could pry the market back open. This single pending opinion is the development most capable of changing everything on this page, which is why the geofencing settlement was written to run independently of it in the meantime.

Nevada is aggressive, but it is not alone, and seeing where it sits sharpens what makes its approach distinct. Arizona went further in one respect: its attorney general brought a 20-count criminal information against Kalshi in March 2026 — the only criminal prosecution any state has attempted — and a federal judge there converted a restraining order into a permanent injunction on May 5, 2026, one of the first merits-stage rulings that federal law preempts state gambling statutes as applied to these markets. New York opened two fronts, with a federal loss for Kalshi in early July and a state-court petition from Attorney General Letitia James on July 31, 2026 seeking penalties that reporting suggested could reach into the billions. Minnesota actually passed a statutory ban, only to watch a federal judge block it on July 27, 2026 before it took effect.

What separates Nevada is neither the harshest penalty nor the first ban but the completeness and the machinery. It moved earliest, in March 2025. It sued the entire top tier rather than a target or two. It won at the state trial level, survived the Nevada Supreme Court, and then did something no other state has done — turned a contempt threat into a court-supervised, vendor-specific geofencing order with a daily money penalty attached. Where other states are still arguing about whether they can block these platforms, Nevada has already made a platform pay a third-party geolocation firm to keep Nevadans out under threat of $120,000 a day. It is enforcement that has moved from theory to plumbing. The one thing Nevada has not done is legislate; its whole campaign runs on the existing gaming law and the courts, which is exactly why the Ninth Circuit’s read of that law carries so much weight here.

• The August 12, 2026 geofence deadline. Whether Kalshi certifies full GeoComply compliance on time, invokes the affidavit clause to explain a delay, or starts owing $120,000 per day is the nearest concrete milestone.
• The Ninth Circuit opinion. Pending since the April 16 argument; a ruling for Nevada makes a circuit split and pushes toward the Supreme Court, while a ruling for the platforms could unwind the state injunctions.
• The Kalshi and Polymarket merits cases in Carson City. The current orders are preliminary injunctions, not final judgments; the underlying cases still have to be decided.
• Any Nevada legislative move. The state has fought entirely through its regulator and courts so far, not through a new statute; watch for whether lawmakers try to codify the Board’s position.
• Voluntary re-entry by Crypto.com, Robinhood or Coinbase. Because they left on their own rather than under injunction, they are the operators best positioned to return fast if the federal winds shift.
