Why prediction markets are legal in Connecticut, for now
Prediction market apps sell event contracts: yes-or-no questions that pay $1 if the answer is yes. The CFTC regulates the exchanges that list them.
The apps say federal oversight overrides state gambling law. Connecticut says it does not, at least for sports.
So far the state is winning the argument. On August 10, 2026, a federal judge in Connecticut refused to block its order against Kalshi.
Winning the argument is not the same as an order. No court has told any app to leave Connecticut.
Here is who offers what, and where each fight stands.
Which prediction market apps work in Connecticut
Most apps we rank accept Connecticut residents. Ten have been ordered to stop sports contracts, but we found none that has announced a shutdown here.
The sportsbook brands work differently. DraftKings and FanDuel run licensed sportsbooks here, so their prediction apps skip sports.
Fanatics Markets and PrizePicks list no sports contracts in Connecticut either. Interactive Brokers lists none anywhere.
Polymarket's position is its own story. Our page on whether Polymarket is legal in Connecticut covers its September order.

How a prediction market trade works
Every contract is a yes-or-no question. It pays $1 if the answer is yes and nothing if it is no.
The price is the crowd's odds. A contract at 60¢ means traders put the chance at about 60%.
Say the Patriots are 60¢ to win on Sunday on Kalshi. You buy 100 contracts for $60, plus a $1.68 fee.
If they win, you collect $100, a $38.32 profit. If they lose, you are out $61.68.
You can also sell before the result, at whatever the market pays then. New to this? Start with what prediction markets are.
What Connecticut has said about prediction markets
Connecticut's Department of Consumer Protection has sent cease-and-desist orders in two waves.
The first, on December 3, 2025, went to Kalshi, Robinhood and Crypto.com. The second, on September 10, 2026, went to nine apps.
Both waves target sports contracts. The state's lawyers told a federal judge that its Kalshi letter covers sports only.
Governor Ned Lamont said the apps “are not being truthful when they tell consumers that their activities are legal.”
The state also sent nearly 30 subpoenas. They went to payment firms, sports data providers, app stores and Connecticut media outlets.
Comptroller Sean Scanlon warned in August of a “dark side” to the apps' growth, from gambling addiction to insider trading.
The court cases that shape Connecticut's rules
Five cases sit in Connecticut's federal court, with the Second Circuit above it. That appeals court has never ruled on the question.
The biggest is Kalshi's. On August 10, 2026, Judge Vernon D. Oliver concluded its sports contracts are not swaps, so state gaming law applies.
He denied Coinbase the same relief that day. Both companies have appealed, and the Second Circuit will hear them in tandem.
The state then went on offense. It sued Kalshi on August 26, and a fight over which court hears that case is still open.
The CFTC is on the other side. It sued Connecticut on April 2 and asked for a preliminary injunction on September 11.
Underdog joined in on September 15, suing over its own order. Our page on whether Kalshi is legal in Connecticut covers Kalshi's case in full.
What Connecticut residents can trade
Sports lead, and here they are the contested part. Contracts cover the NFL, NBA, MLB and college games.
UConn is the local draw. Connecticut bars its sportsbooks from taking bets on in-state college teams, outside tournaments of four or more teams.
Kalshi lists them anyway. UConn plays Syracuse on October 3 and Temple on October 10, both on Kalshi's board.
Politics is the other big market. Lamont seeks a third term against Republican Ryan Fazio on November 3, 2026, and Kalshi lists the race.
Economics, crypto and weather markets round it out. None of them is named in the state's orders.
The risks for Connecticut traders
The law could turn quickly. A court order could close sports contracts here. In Michigan, a court deal made Robinhood close open sports positions.
Connecticut's orders tell the apps to let residents withdraw their funds. Keep only what you are trading in any account.
You can lose everything you put into a contract. A 90¢ favorite that loses pays nothing.
Taxes apply. Connecticut taxes the profits as income, at rates up to 6.99%. How the IRS treats event contracts is not settled.
Trade only what you can afford to lose. Connecticut's Problem Gambling Helpline is 1-888-789-7777, and our responsible trading guide has more.
What could change for Connecticut traders
Three things could. The first is the Second Circuit, whose panel will rule on Kalshi's and Coinbase's requests for an injunction.
The second is the state's own case. If it returns to Hartford Superior Court, the state can press its request to block Kalshi's sports contracts.
The third is the CFTC's case, or the Supreme Court. New Jersey has asked the justices to settle the question for every state.
Our litigation tracker follows each of these cases.

Prediction markets vs sports betting in Connecticut
Sports betting is legal in Connecticut. Online betting opened on October 19, 2021, after a week-long soft launch.
It runs through the state's two tribes and its lottery. DraftKings partners with Foxwoods, FanDuel with Mohegan Sun, and Fanatics with the Connecticut Lottery.
The tribes say Connecticut bettors have wagered more than $7.4 billion since 2021. They put 2025 sports betting revenue at $265.9 million.
Sportsbooks pay 13.75% of revenue in tax and serve only adults 21 and over. Prediction apps hold no state license and mostly take traders from 18.
If a problem comes up on an app, you complain to the app first, then to the CFTC. The state says it has no way to recover lost funds for you.
How to choose a prediction market app in Connecticut
Start with what you want to trade. For politics or the economy, the state's orders are aimed elsewhere.
For sports, weigh the legal risk first. Nearly every app we rank that offers sports here has received a state order.
Then compare fees. They vary more than prices do. Our fee comparison works out each app's cost on the same trade.
Our app rankings score every app on the same six criteria. Each review covers fees, payouts and the lawsuits against it.
