Prediction Market Sites For USA Players

An event contract is a yes/no question with a price attached. Will the Chiefs win on Sunday? Will the Fed cut rates in September? Will a named film win Best Picture? Each contract settles at $1 if the answer is yes and zero if the answer is no, and until settlement it trades at a price between 1 cent and 99 cents that reflects what the market thinks the probability is. If yes shares on a game trade at 60 cents, the market collectively believes the team has about a 60% chance to win. Buy at 60 cents and win, you collect $1 per contract, a 40-cent profit. Lose and the contract expires worthless.

Three structural differences separate this from a sportsbook:

• You trade against other people, not the house. A prediction market is an exchange matching buyers and sellers, like a stock market. The platform earns fees on trades rather than profiting when you lose, which removes the house edge baked into sportsbook odds.
• You can sell before the outcome. Buy yes on a team at 40 cents, watch them take a big lead, and you can sell at 80 cents before the game even ends, locking in profit or cutting losses the way a trader exits a stock position. Sportsbook cash-out features imitate this, but on an exchange the exit price is set by the market, not by the book.
• Prices are probabilities, and the fee is visible. Instead of -110 lines with vig hidden inside, you see a bid, an ask and a small per-contract trading fee. For sharp bettors, the all-in cost of a prediction market trade is often lower than the equivalent sportsbook wager; the trade-off is that you pay a spread on thin markets.

Categories run far beyond sports. Kalshi and Polymarket list contracts on elections, inflation prints, jobs reports, interest rates, weather, awards shows, box office numbers and viral news events. That breadth is the product's identity: it is one part betting site, one part news ticker and one part financial market, and the prices themselves have become a media staple, quoted as the odds of everything from a government shutdown to a Supreme Court ruling.

Here is the most important thing to understand about this section: prediction markets do not have a state-by-state license map the way sports betting or DFS does, because the platforms do not hold state licenses at all. They operate nationally under federal CFTC oversight, and the state question is not "which states have legalized them" but "which states are fighting them and what has happened in court." As of mid-2026 the map breaks into three tiers.

Tier 1: Available With Full Menus (Roughly 43 States)

In the large majority of states, every platform on this page is available to adults 18 and older with its complete contract menu, sports included. This tier includes the biggest prizes in American gambling, the states that have never legalized online sports betting: California, Texas, Florida and Georgia, where DraftKings Predictions, FanDuel Predicts, Kalshi, Polymarket and the rest now offer sports event contracts to tens of millions of people who previously had no legal way to wager on games. No registration with any state is required, no state geolocation wall applies and signing up takes minutes with standard identity verification.

Tier 2: The Contested States

A second group of states has taken formal action, cease-and-desist orders, lawsuits or both, against one or more platforms, arguing that sports event contracts are unlicensed sports betting under state law. The platforms have generally sued in federal court claiming the Commodity Exchange Act preempts state gambling law, and the results have split. In most contested states the apps remain usable while litigation continues, sometimes with sports contracts removed. State by state:

• Nevada: The most aggressive state and the platforms' worst defeat. The Nevada Gaming Control Board sent Kalshi a cease-and-desist in March 2025, a federal district court ruled for Nevada in November 2025, finding sports event contracts indistinguishable from gambling, and in March 2026 the Ninth Circuit let Nevada's temporary ban take effect. Kalshi pulled sports, election and entertainment contracts for Nevada users, who currently see a sharply reduced menu. The appeal continues, with oral arguments heard in April 2026.
• New Jersey: The platforms' biggest win. A federal district court enjoined New Jersey's enforcement in April 2025, and on April 6, 2026, the Third Circuit affirmed in a 2-1 decision, holding that sports event contracts fall within the federal swap definition and that states cannot block them. Apps operate normally in New Jersey under that ruling.
• Maryland: A state win that still stands. A federal judge denied Kalshi's preliminary injunction in August 2025, finding state gaming authority can coexist with CFTC regulation, and the Third Circuit's New Jersey ruling does not bind Maryland, which sits in the Fourth Circuit. Maryland enforcement continues, making it one of the riskier states for sports contracts.
• Ohio: Followed Nevada's reasoning. An Ohio federal court denied Kalshi's injunction request in March 2026, warning that Kalshi's theory would force every sports bet in the country onto federal exchanges and put every sportsbook out of business. Litigation continues.
• Tennessee: The state's Sports Wagering Council sent cease-and-desist letters to Kalshi, Polymarket and Crypto.com demanding they void contracts and refund residents, but a federal court granted Kalshi a preliminary injunction in February 2026, finding its products are likely legal swaps under federal law. Platforms continue operating during the appeal.
• Arizona: The only state to bring criminal charges, filing 20 counts against Kalshi in March 2026 for operating an unlicensed gambling business. A federal judge quickly blocked the prosecution with a restraining order at the CFTC's request, and the constitutional fight continues.
• Massachusetts: The attorney general sued Kalshi and Robinhood, accusing them of running illegal unlicensed sports betting. The case is active and the apps remain available.
• Connecticut: Issued cease-and-desist orders to Kalshi, Robinhood and Crypto.com in December 2025, and is among the states the federal government has since sued.
• New York: Has moved against several platforms over sports markets, and users there are barred from sports-based contracts on Kalshi while non-sports markets remain open. Legislation to put prediction market operators under state financial regulation has been proposed.
• Illinois and Montana: Both issued cease-and-desist orders, Illinois targeting Polymarket, Kalshi, Crypto.com and Robinhood over unlicensed sports wagering. Illinois also became a federal lawsuit target, and its governor signed an executive order barring state employees from trading on insider information.

Two more fronts are worth knowing. First, tribal gaming: Wisconsin's Ho-Chunk Nation sued Kalshi and Robinhood in 2025, arguing event contracts violate federal Indian gaming law and tribal sovereignty, an argument other tribes are watching closely. Second, the federal government has gone on offense, with the CFTC and Justice Department suing Arizona, Connecticut and Illinois on April 2, 2026, seeking to block state enforcement outright, an extraordinary posture of federal agencies suing states to protect betting platforms.

Tier 3: Banned. Minnesota Stands Alone

In May 2026, Minnesota became the first state to enact an outright prediction market ban, a law signed by Gov. Tim Walz making it a felony to operate, host or advertise prediction markets in the state, effective Aug. 1, 2026. The law targets companies rather than individual users and passed both chambers by wide bipartisan margins. The federal government sued immediately, asking a court to block the law before it takes effect, so even the country's only true ban is in legal limbo. If you live in Minnesota, watch this case; platform availability after Aug. 1 depends entirely on how it goes.

The Scorecard and What Comes Next

Add it up and the litigation map looks like this: courts in New Jersey and Tennessee have sided with the platforms, courts in Nevada, Maryland and Ohio have sided with the states, the Third Circuit has issued the first appellate ruling for federal preemption and a contrary Ninth Circuit ruling in the Nevada case would create a circuit split, the classic setup for Supreme Court review. Traders on the platforms themselves price a strong chance the Supreme Court takes a sports event contract case. Until the high court or Congress settles it, expect the contested list to keep growing and contract menus to flicker state by state.

For readers coming from sportsbooks or daily fantasy, here is how the three products line up. The comparison explains both why prediction markets grew so fast and why state regulators are so angry: the product reaches states the other two cannot, at a lower legal age, with no state taxes collected.

The DFS parallel runs deeper than the table shows. Industry analysts describe prediction markets as the new DFS playbook: in 2015, DraftKings and FanDuel used fantasy contests to build customer bases in states without legal betting, then converted those customers when sports betting legalized. Their prediction apps repeat the move, gathering deposits and registrations in California, Texas and Florida today so the relationships exist the day those states legalize. Whether you find that clever or cynical, it tells you the industry's biggest players expect prediction markets to be a durable part of the landscape.

The entire fight comes down to one question: is a yes/no contract on a football game a financial instrument or a sports bet? Federal law, the Commodity Exchange Act, gives the CFTC exclusive jurisdiction over swaps and futures traded on registered exchanges, and the platforms argue their event contracts are exactly that, swaps, meaning state gambling laws simply do not apply to them, the same way a state cannot regulate trading on the Chicago Mercantile Exchange. The Third Circuit accepted that argument in April 2026. States answer that calling a bet a swap does not change what it is, that gambling regulation has belonged to the states for two centuries and that Congress never intended the CFTC to license a national sportsbook. The Nevada, Maryland and Ohio courts found that persuasive, with one judge calling Kalshi's offerings virtually indistinguishable from DraftKings and FanDuel.

Three things could settle it. First, the Supreme Court: a circuit split is forming, and most observers expect the justices to take a case, with a decision that would bind every state at once. Second, Congress: a bipartisan Senate proposal would ban CFTC-licensed platforms from offering sports event contracts specifically, which would gut the sports product while leaving politics and economics markets intact. Third, the CFTC itself: on June 10, 2026, the agency published a proposed rule to define which event contracts are permissible, blessing most sports markets while moving to ban contracts vulnerable to manipulation, such as bets on individual player injuries, referee decisions and specific in-game events, along with contracts on war, terrorism and assassination. The rule is open for public comment and would, if finalized, give the industry its first comprehensive federal rulebook.

In the meantime the regulator has also turned to policing the markets themselves. The CFTC issued an advisory in early 2026 warning it will aggressively pursue trading on material nonpublic information, platforms have fined and banned traders including public officials, Kalshi barred athletes and politicians from trading on its platform and Illinois ordered state employees off insider trades by executive order. Insider trading on event contracts, who knows the jobs number early, which athlete knows he is sitting out, is shaping up as the industry's next big integrity question.

Signing up at a prediction market looks more like opening a brokerage account than registering at a sportsbook, but it is fast. You will provide your name, address, date of birth and Social Security number for federally required identity verification, which usually clears in minutes. The minimum age is 18 on every major platform, not 21, because these are commodity exchanges rather than casinos. There is no state-by-state geolocation wall for non-sports markets, though platforms do enforce contract-level restrictions in contested states, so a user in Nevada may see sports markets grayed out while economics and politics contracts trade normally.

Funding is straightforward dollars at most platforms: ACH bank transfers and debit cards at Kalshi, DraftKings Predictions, FanDuel Predicts and Robinhood, with withdrawals back to your bank typically clearing in one to a few business days. Polymarket US supports standard deposits with an optional stablecoin route, and Crypto.com's OG.com leans crypto-native. Two warnings worth setting expectations on. First, bonuses are thin compared with sportsbooks; you will see modest trade-matching offers rather than four-figure bonus bets, because exchanges earn small fees rather than house edge. Second, taxes are genuinely murky: winnings are taxable income like any gambling or trading profit, but the IRS has issued no formal guidance on how event contracts are classified, and Kalshi does not issue 1099-B forms for contract trades, so keep your own records and talk to a tax professional if you trade serious volume.

Prediction markets reward a slightly different skill set than sports betting, and the differences are where new traders leak money.

Think in probabilities, not picks. A contract at 70 cents is not asking whether the favorite will win; it is asking whether the true probability is higher or lower than 70%. Profitable trading means buying when your estimate beats the price and passing when it does not, even on outcomes you expect to happen. Paying 95 cents for a near-lock is still a bad trade if the real probability is 93%.

Respect the spread and the fees. On liquid markets like an NFL game or a Fed decision, the gap between bid and ask is a penny or two and fees are trivial. On a thin market, an obscure award category, a long-dated political contract, you can lose several cents just entering and exiting. Check the order book depth before sizing up, use limit orders rather than market orders and remember that per-contract fees compound across high-volume strategies.

Use the exit. The ability to sell before settlement is the product's biggest structural edge over a sportsbook, and most casual users never touch it. Position moves your way early, you can take profit; news breaks against you, you can salvage most of your stake instead of riding to zero. Treating contracts as tradable positions rather than tickets to sweat is the single biggest upgrade in approach.

Finally, bankroll rules do not change because this is called trading. Event contracts are binary, variance is brutal, and the 18-year-old minimum age means plenty of users are learning expensive lessons in public. Risk a small fixed fraction per position, never average down on a thesis the news has already killed and treat any money in a prediction market account as money you can afford to lose entirely.

• Think in probabilities, not picks
• Respect the spread and the per-contract fees
• Check order book depth before sizing up
• Use limit orders rather than market orders
• Use the exit; sell before settlement when it pays
• Risk a small fixed fraction per position

Our rankings weigh, in order: regulatory standing and exchange licensing, liquidity and market depth at the contracts Americans actually trade, state availability including how a platform handles contested states, fees and spreads as an all-in cost of trading, deposit and withdrawal quality, breadth of market categories and app experience. Because the legal map shifts monthly, we re-verify state-level availability and litigation status continually, and this page reflects the market as of mid-2026.

Prediction markets are the most consequential new product in American gambling since legal sports betting, and 2026 is the year they stopped being a novelty. A federal licensing structure has let them reach every big state the sportsbooks cannot touch, the biggest gambling brands in the country have stopped fighting them and started copying them, real institutional money from CME to the NYSE's parent company has poured in and the courts are now deciding whether the whole model survives contact with state gambling law. For players, the practical takeaways are simpler than the legal saga: Kalshi is the default choice for depth and liquidity, Polymarket US is the challenger to watch, Robinhood is the easiest first step, and DraftKings Predictions and FanDuel Predicts are purpose-built for the states where sports betting still is not legal.

Go in with clear eyes. This is a fast-moving, lightly mapped corner of the betting world where a court ruling can change your app overnight, the tax treatment is unsettled and the line between trading and gambling is thin by design. Start small, learn the mechanics on liquid markets, keep records and check the current status of your state before you deposit.
