Tennessee Prediction Markets: How Kalshi Beat the State’s Toughest Gambling Regulator

Yes, as a practical matter, and Kalshi’s sports contracts specifically are shielded by a federal court order — but the underlying question is contested and on appeal, so “legal” here means “protected for now,” not “settled forever.” Tennessee’s regulator considers these products unlicensed sports betting and tried to shut them off. A federal judge disagreed, blocked the state, and let the contracts keep flowing. Until a higher court says otherwise, that injunction is the law of the case.

The mechanics of how that came to be are worth understanding, because Tennessee reached a pro-platform result through an unusually confrontational path. Prediction-market operators run nationwide by registering with the Commodity Futures Trading Commission and treating their event contracts as derivatives rather than wagers. The Tennessee Sports Wagering Council rejected that framing outright and, on January 9, 2026, ordered Kalshi, Polymarket, and Crypto.com to stop offering sports contracts, cancel open positions, and refund Tennessee customers. Kalshi answered by suing the council’s leadership and the state attorney general in federal court that same day. On February 19, 2026, U.S. District Judge Aleta Trauger granted Kalshi a preliminary injunction, finding the company likely to prove that its sports event contracts are swaps under the Commodity Exchange Act and that federal law probably preempts Tennessee’s sports gaming scheme as applied to them.

So the honest status for a resident: Kalshi is court-protected and openly available, and no ruling has removed it or the other CFTC-registered platforms from the state. What you do not have is certainty. The state is appealing to the U.S. Court of Appeals for the Sixth Circuit, which heard argument on July 30, 2026 and has not ruled. If that court reverses, Tennessee’s order could snap back into force. The contracts are reachable today because one company chose to litigate instead of leave, and won the opening round — which is a very different foundation than a legislature affirmatively welcoming these markets.

To grasp why Tennessee’s prediction-market outcome is surprising, start with how rarely the state’s regulator loses. Tennessee runs one of the more centralized and assertive gambling-enforcement operations in the country, built on top of a sports-betting system unlike any other state’s, and it spent 2025 and 2026 methodically removing operators it deemed illegal.

Three campaigns ran in parallel, and they are constantly confused for one another. The first targeted offshore sportsbooks — the overseas sites that take Tennessee bets without any state license. The Sports Wagering Council issued cease-and-desist letters and, when operators ignored them, imposed civil penalties of $50,000 apiece on more than a dozen of them. Those books have no legal footing in the United States, so the penalties stuck and the campaign drew little pushback.

The second campaign went after sweepstakes casinos, the dual-currency social-gaming sites that argue they are not gambling because players use virtual coins. Attorney General Jonathan Skrmetti’s office sent cease-and-desist letters to unlicensed sweepstakes operators in late 2025, treating their games as illegal lotteries under Tennessee law. Major brands including Chumba Casino, Fortune Coins, Global Poker, LuckyLand, and Zula read the room and exited before the state even finished legislating. Lawmakers then codified the result: House Bill 1885 and its Senate companion, signed in May 2026, made offering an online sweepstakes casino to Tennesseans flatly illegal. By the count regulators later gave, roughly 38 sweepstakes brands were pushed out. That fight, too, ended in a clean state win.

The third campaign was prediction markets, and it is the only one of the three that produced a courtroom defeat for Tennessee. The council used the same playbook — a cease-and-desist demanding immediate withdrawal — but this time the target had a federal registration and a legal theory that had already won elsewhere. Kalshi did not behave like a sweepstakes brand or an offshore book. It went to federal court and got the state’s order frozen. The contrast is the whole point: keep those three tracks separate as you read on, because a headline about Tennessee “banning” one form of online gambling almost never refers to the prediction-market case, which the state is currently losing.

The document that started the legal fight was blunt. On January 9, 2026, the Tennessee Sports Wagering Council sent cease-and-desist letters to Kalshi, Polymarket, and Crypto.com, asserting that each was offering sports wagering to Tennesseans without the license the state’s Sports Gaming Act requires. The letters did not ask the companies to adjust their products or apply for approval. They ordered them to stop immediately.

The specifics carried real teeth. Each operator was told to halt all sports contracts available to Tennessee residents, void open positions, and refund Tennessee customers by January 31, 2026. The council framed the activity as unlicensed sports betting that also violated Tennessee’s consumer safeguards — most pointedly the age rules, since Tennessee sets 21 as the minimum for legal sports wagering while these exchanges admit users at 18. The letters warned of civil penalties reaching $25,000 per violation and raised the specter of criminal exposure for promoting gambling. For Polymarket, freshly relaunched in the United States after years offshore, it was reportedly the first state-level cease-and-desist it had faced since reentering the domestic market.

The council’s authority for all of this traces to the Tennessee Sports Gaming Act, the 2019 law that legalized online sports betting in the state, and to the independent regulator the legislature later created to enforce it. From the state’s vantage point the logic was simple: a contract that pays a Tennessean if the Titans win is a bet on the Titans, whatever the platform calls it, and anyone booking that action needs a Tennessee license, must verify players are 21, and owes the state’s tax. No prediction-market operator held such a license. That, the council argued, ended the analysis.

Two of the three recipients did not test the theory in court. Polymarket and Crypto.com received the same order Kalshi did but did not file their own lawsuits, which left them without the judicial protection Kalshi went on to secure — a distinction that still matters for anyone weighing which app to trust in Tennessee today. Kalshi took the opposite path, and it took it fast.

Rather than absorb the order, Kalshi filed suit in the U.S. District Court for the Middle District of Tennessee on January 9, 2026 — the same day the letter arrived. The complaint named the Sports Wagering Council’s leadership, including chairman William Orgel and executive director Mary Beth Thomas, along with Attorney General Jonathan Skrmetti, and argued that Tennessee had no authority to regulate a CFTC-registered exchange or to force it out of the state. The case is captioned KalshiEX LLC v. Orgel.

Judge Aleta Trauger moved quickly. She granted a temporary restraining order on January 12, 2026, freezing the state’s order almost before it could take effect, and then converted that TRO into a preliminary injunction on February 19, 2026 after fuller briefing. Kalshi was required to post a $500,000 bond as a condition of the injunction — standard security in case the state ultimately prevails — but the practical effect was immediate: Tennessee could not enforce its cease-and-desist against Kalshi while the case proceeded.

Trauger’s reasoning is what made the ruling travel. She concluded that Kalshi was likely to succeed on the merits because its sports event contracts fit the statutory definition of a “swap” under the Commodity Exchange Act, which would place them within the CFTC’s domain and preempt Tennessee’s conflicting gambling law. Where Tennessee argued that a swap must turn on the “occurrence” of an event and that a game’s result is a mere “outcome” rather than an occurrence, Trauger was unpersuaded — reasoning that the result of an event can itself be an occurrence within the statute’s meaning. She leaned on Congress’s own word choice, noting that the law reaches contracts tied to the “potential” financial consequences of an event, a deliberately broad formulation lawmakers could have written more narrowly and did not.

The opinion also trimmed the defendant list on sovereign-immunity grounds. Trauger dismissed the Sports Wagering Council itself as an arm of the state that cannot be sued directly, while allowing the case to proceed against the individual officials responsible for enforcement — the standard route for getting an injunction against a state agency’s conduct without suing the agency as an entity. That procedural cleanup did not soften the outcome for Tennessee: the officials who would actually enforce the order were the ones now barred from doing so.

Set against the national map, Trauger’s ruling landed on the platform-friendly side of a deepening divide. Around the same window, federal judges in Ohio, Nevada, and Maryland reached the opposite conclusion, holding that sports contracts look enough like betting to stay under state control. Tennessee’s decision became one of the more explicit and frequently cited applications of the swap-and-preemption theory in the platforms’ favor, and it is the version of the argument the state is now trying to overturn on appeal.

Tennessee did not accept the loss. The state appealed Trauger’s injunction to the U.S. Court of Appeals for the Sixth Circuit, where the case carries the docket number 26-5235, KalshiEX LLC v. William Orgel. What makes the appeal distinctive is its traveling companion. The Sixth Circuit paired Tennessee’s case for argument with a Kalshi appeal out of Ohio, No. 26-3196, and the two states could hardly present a starker contrast: Tennessee’s district judge ruled for Kalshi, while Ohio’s ruled against it. One appellate panel is now weighing both framings of the identical question at once.

Argument took place on the morning of July 30, 2026 in Cincinnati and ran well past its scheduled time. Judge Eric L. Clay led the questioning, and the tenor was skeptical of the platforms. Clay pressed Kalshi’s counsel on the company’s dismissiveness toward state regulators and lawmakers, questioning the premise that federal oversight is automatically better for the public than a state’s own judgment, and the panel dug into a threshold problem the platforms would rather leapfrog: whether a contract on a game even fits the statutory definition of a swap before anyone reaches the preemption question. Coverage described Kalshi’s attorneys taking sustained fire from the bench. The CFTC, which had filed briefs supporting Kalshi, asked for time to argue as an amicus and was denied a speaking role.

Right through August 2, 2026, the panel had not issued a decision, and the stakes cut both ways for Tennessee. If the Sixth Circuit affirms Trauger, Kalshi’s protection in Tennessee hardens and the platforms gain a second appellate win to set beside the Third Circuit’s New Jersey ruling. If the court reverses, Tennessee’s cease-and-desist could be revived and the state would join Ohio in an appellate ruling against the platforms — and because the Third Circuit already ruled the other way, a Sixth Circuit loss for Kalshi would sharpen the circuit split that pushes this whole question toward the Supreme Court. Either way, the Tennessee answer that reads as settled today is one appellate opinion away from changing.

A telling absence sits at the center of Tennessee’s story. Under its current leadership the Commodity Futures Trading Commission has taken an aggressive posture defending its turf, filing suit against nine states it accused of trespassing on federal authority over event contracts — Arizona, Connecticut, Illinois, New York, New Mexico, Minnesota, Rhode Island, Wisconsin, and Kentucky. Tennessee is not on that list, and the reason is instructive: the CFTC sues states that are winning against the platforms or threatening to. In Tennessee, the platform already won. Kalshi’s injunction did the CFTC’s work for it, so the agency had no order to unwind and no live enforcement to block. It contributed amicus support to the appellate effort instead of opening a new front.

That dynamic reveals something about where Tennessee actually sits in the national fight. The state is not a quiet jurisdiction that never bothered these markets — its regulator moved early and hard. It is a jurisdiction where the platforms happened to draw a favorable district judge, which flipped the litigation posture and made federal intervention unnecessary. The federal government’s broader stance under this administration has leaned toward protecting the exchanges: it dropped an earlier appeal over election contracts, withdrew a proposed restrictive rule, and its chairman warned in early 2026 that the agency would sue any state regulator interfering with a federally licensed operator. Tennessee’s regulator did interfere — and the only reason it avoided a CFTC lawsuit is that a Nashville courtroom stopped it first.

Understanding Tennessee’s hostility to these products requires understanding how strange its own sports-betting system is. When lawmakers legalized wagering through the 2019 Sports Gaming Act, they built something no other state has copied: an online-only market with zero retail sportsbooks. There is no betting window at a casino because Tennessee has no commercial casinos; the entire legal market lives on phones, administered as an extension of state gaming policy rather than a casino-floor add-on. Regulation began under a council tied to the state lottery apparatus before the legislature spun off the independent Sports Wagering Council to run it.

The tax design is just as unusual. Since July 1, 2023, Tennessee has taxed sportsbooks at 1.85 percent of total handle — the raw dollar volume of bets placed — rather than on the revenue operators keep after paying winners. It is the only state in the country that taxes handle instead of revenue, a structure that guarantees the state a fixed cut of every dollar wagered regardless of how the games break. That model matters to the prediction-market fight in a concrete way: when the Sports Wagering Council looks at a Kalshi sports contract, it sees activity that, if treated as betting, would owe that 1.85 percent and require a license — and sees an operator paying neither. The state’s grievance is not abstract turf-guarding; it is a licensed, taxed, age-gated system watching an unlicensed, untaxed, 18-and-up competitor take the same action.

That is precisely the gap the platforms exploited, and precisely why Tennessee reacted so fast. A resident who wants to bet on a game already has a legal, regulated route. Prediction markets offered a parallel route that sidestepped the license, the tax, and the 21-and-up rule — and did it under a federal banner the state could not easily pierce. The council’s cease-and-desist was an attempt to force that parallel market back into the state’s system. Trauger’s injunction is what kept the parallel market open.

Behind the legal labels, the product is straightforward, and seeing the mechanics clarifies why the classification fight is so hard to resolve. A prediction market lists a yes-or-no question — will a team win, will a figure land above a line — and lets you buy shares of either answer. Prices sit between one cent and 99 cents and function as a live probability read: a contract trading at 58 cents implies the market thinks the event is about 58 percent likely. Correct contracts settle at one dollar, wrong ones at zero, and your profit is the spread between your entry price and the resolution.

The structural argument the platforms press is about who takes the other side of your position. At a Tennessee-licensed sportsbook, the operator is your counterparty — it sets the odds, holds the risk, and profits when you lose. On an exchange-style prediction market, you are matched against another trader who took the opposite view, with the platform running the order book and skimming a fee rather than betting against you. That peer-to-peer framing is the backbone of the claim that these are financial instruments, not wagers, and it is the framing Trauger found likely to prevail. Tennessee’s counter is the one Judge Clay pushed at the Sixth Circuit: from the standpoint of a resident staking money on a game and collecting if it hits, the identity of the counterparty does not change the economic substance of a sports bet. Complicating the picture further, some products reach you through a broker or distributor rather than a native exchange, which is why the fight increasingly turns on which specific contracts are at issue rather than which company offers them.

The catalogs on these platforms reach far beyond sports. Depending on the operator, a Tennessee trader can find contracts across several categories:

Markets on economics and politics have drawn comparatively little enforcement anywhere, and the federal government has long tolerated them. Tennessee’s objection is aimed almost entirely at the sports category. The Sports Wagering Council’s authority runs to sports wagering, and its January order singled out sports contracts — not markets on the Federal Reserve or a Senate race. The practical implication for a resident is a sliding scale of risk: the closer a contract sits to a sporting event, the more squarely it lands inside the exact dispute Trauger is refereeing, and the further it drifts toward economics, politics, or entertainment, the less it resembles the thing Tennessee is trying to regulate. That gradient also tracks where the national litigation is drifting, as even judges sympathetic to the platforms have begun asking whether every contract on the board genuinely qualifies as a swap or only some of them do.

The rest of the platforms we review that list or distribute event contracts under the same Tennessee legal cloud include DraftKings Predictions, which launched a wide event-contract menu in late 2025, Robinhood, Coinbase, Fanatics Markets, ProphetX, Underdog, and PrizePicks. Note that Novig has publicly listed Tennessee among the states where it does not operate, so do not assume every CFTC brand is live here. For politics-only trading with strict position caps, PredictIt sits outside the sports fight entirely, and the social-first Sleeper and OG.com round out the field we track. Every one of these operates on CFTC registration or a pick’em model rather than a Tennessee license, and each gates sports markets differently, so treat availability as platform-specific. Our prediction markets hub covers each brand in full.

For anyone whose main goal is game wagering, Tennessee already offers a fully legal alternative with none of the appellate uncertainty. The state’s online sportsbooks launched under the 2019 Sports Gaming Act and operate under Sports Wagering Council oversight, complete with a 21-and-up requirement, a state self-exclusion program, licensed operators, and Tennessee consumer protections standing behind every account. A bet placed there is unambiguously legal, taxed, and supervised. A sports contract on a prediction market is a product the state has formally declared unlicensed and tried to shut off — protected today only by a court order that is on appeal.

The practical differences track the legal ones. A licensed Tennessee sportsbook is your counterparty, offering fixed odds and the familiar menu of moneylines, spreads, and props. A prediction market matches you against other traders at prices that drift with the market, which some find fairer and others find harder to read. If a clear legal footing and access to Tennessee’s self-exclusion and complaint systems matter to you, the licensed sportsbook is the unambiguous choice. Compare operators on our Tennessee online sportsbooks page, see which other states have online sportsbooks, or start at the main online sportsbooks hub. For the wider picture of legal wagering in the state, our Tennessee gambling sites guide is the companion piece.

Beneath the jurisdictional dispute sits a plainer concern that runs through the council’s order: prediction-market exchanges operate outside the safety net Tennessee built for gambling. A resident trading sports contracts on a CFTC exchange gets no Tennessee self-exclusion option, no state complaint or dispute-resolution channel through the Sports Wagering Council, and, on most platforms, a minimum age of 18 rather than the 21 the state requires for licensed betting.

FanDuel Predicts is the notable exception, layering on deposit limits, self-exclusion, and support referrals that no law forces on it. The rest of the field leans on federal financial regulation, which was not designed around problem-gambling protection. There is also the open question of your money if a platform is eventually forced out. In other states, operators pushed out by court orders have generally allowed users to settle up and withdraw their account balances, and some orders required it — but there is no Tennessee-guaranteed process for a CFTC exchange, so a balance parked on one of these apps does not carry the account protections a licensed Tennessee sportsbook provides. If the Sixth Circuit reverses and the council’s order revives, that scenario stops being hypothetical.

How prediction-market winnings should be reported is genuinely unsettled, and nothing here is tax advice. Kalshi does not report 1099-B forms for its event contracts, the IRS has published no formal guidance classifying the activity, and tax professionals disagree over whether gains are gambling income, ordinary income, capital gains, or something governed by the futures rules of Section 1256. Products routed through a broker or distributor may be reported differently than exchange-native ones, so the answer can shift depending on which platform you used. Tennessee itself has no state income tax on wages, and it does not levy a personal income tax on this kind of gain, so the reporting questions that matter to a Tennessean are federal ones. The state’s own 1.85 percent handle tax, the one at the heart of the council’s grievance, falls on licensed operators rather than on you as a trader — and the fact that prediction markets pay none of it is part of what Tennessee says makes them unlawful. If you have realized meaningful gains, keep your own records and consult a professional rather than assuming an app will hand you a clean tax form.

Tennessee’s legislature has not been idle while the courts sort out the core question, and lawmakers have floated at least one measure aimed squarely at prediction-market integrity. A bill sponsored by state Senator Ferrell Haile, a Gallatin Republican, would make it a Class E felony to profit from a prediction market on an event whose outcome the trader helped influence — an insider-trading provision rather than a ban on the markets themselves. The measure advanced out of the Senate Judiciary Committee on a near-unanimous vote, with one member abstaining, and was positioned for a possible full Senate vote. It targets the manipulation risk that has surfaced nationally, where people with inside knowledge of an event trade on outcomes they can affect, rather than trying to shut the platforms down. Verify its bill number and current status on the Tennessee General Assembly site or LegiScan before treating anything about it as final, since companion-bill numbering and floor timing shift.

The far larger variable is not in Nashville but in Cincinnati. Whatever the legislature does, the Sixth Circuit’s ruling in the consolidated Tennessee and Ohio appeals will set the terms. An affirmance locks in Kalshi’s protection and strengthens the platforms nationally; a reversal revives Tennessee’s cease-and-desist and, paired with the Third Circuit’s opposite ruling, accelerates the march toward the Supreme Court. Federal moves matter too: a proposed CFTC rule that would define which event contracts are permissible, and a bipartisan bill in Congress that would bar these exchanges from listing sports-betting-style contracts altogether, could each override Tennessee’s fight from above. The state-level watch list is short but consequential.

• The Sixth Circuit ruling in Nos. 26-5235 (Tennessee) and 26-3196 (Ohio) — the single event most likely to change Tennessee’s answer. Pending as of August 2, 2026.
• Senator Haile’s prediction-market integrity bill — whether it clears a full floor vote and becomes law, and its final scope.
• Any Supreme Court petition flowing from the circuit split, which would put the swap question before the nation’s highest court.
• The CFTC’s event-contract rulemaking, which could define federally which sports contracts survive.
• Platform footprints inside Tennessee — watch whether Polymarket or Crypto.com quietly geofence the state given they lack Kalshi’s injunction.

Placed alongside its peers, Tennessee occupies an unusual slot: an aggressive regulator that nonetheless produced a pro-platform result, thanks to the judge who drew the case.

• Ohio is Tennessee’s courtroom opposite and its appellate partner. Ohio’s federal judge rejected the swap theory and called the platforms’ reading absurd, and the state is chasing a 5 million dollar fine — which is exactly why the Sixth Circuit paired the two cases, letting one panel weigh a pro-Kalshi ruling and an anti-Kalshi ruling side by side.
• Nevada pushed hardest on enforcement, winning a state-court block and driving Kalshi toward contempt exposure after the company refused to geofence — a harder line than Tennessee, whose district court stopped the state before enforcement could bite.
• New York ran parallel federal and state tracks and escalated to a state-court petition seeking penalties reported in the tens of billions, built on the same unlicensed-operation and under-21 arguments Tennessee raised in its January order.
• Arizona went furthest of all, bringing criminal charges and securing the first district-level merits ruling that federal law preempts state gambling law — the mirror image of Tennessee’s early-stage injunction.
• New Jersey produced the Third Circuit’s pro-Kalshi appellate win, the ruling Tennessee’s outcome most resembles and the precedent the platforms will lean on if the Sixth Circuit affirms.

What sets Tennessee apart within that group is the mismatch between temperament and result. Its regulator behaves like Nevada’s or Ohio’s — fast, confrontational, willing to fine and to litigate — yet its scoreboard against prediction markets reads like New Jersey’s, a platform win. That gap between how hard Tennessee fought and how the fight has gone so far is the state’s signature, and it holds only as long as Trauger’s injunction survives appeal.
