Connecticut Prediction Markets: Best Sites & Legal Apps in 2026

Best prediction market apps in Connecticut

This guide compares the best prediction markets in Connecticut and covers current promos and the state’s regulatory landscape.

Are prediction markets legal in Connecticut?

Yes, as long as you are using an exchange that has registered with the US Commodity Futures Trading Commission (CFTC) and you meet the eligibility requirements. Each of our exchange recommendations on this page is in good standing with the CFTC. 

However, residents need to pay attention to ongoing litigation challenging the legality of sports event contract trading in the state. CT Attorney General William Tong has sued Kalshi, alleging that activity on its platform violates Connecticut’s gambling laws.

The US District Court for the District of Connecticut and the US Second Circuit Court of Appeals may rule on that dispute plus the CFTC’s lawsuit against Tong at any time. An unfavorable ruling for the CFTC and/or Kalshi in those cases might restrict access to sports event contracts in CT.

People in Connecticut can follow all of the updates on these disputes using DeFiRate’s Litigation Tracker.

How to trade prediction markets in Connecticut

Connecticut expanded its framework for legal gambling to include online gaming in 2021, which means that people in the state have had years to become familiar with the process of maintaining an account for those apps and websites. Getting started with prediction market trading in CT bears several resemblances to its simple six-step process.

1. Select an exchange: Look for proof that the platform has registered with the CFTC and accepts trades from people in CT. Verify that the exchange offers the markets that you want to trade in and compare its fees.
2. Share your account details: You can’t trade on a CFTC-approved exchange without providing your contact information and verifying your identity. In most cases, you’ll be able to establish your identity using government-issued documents like a driver’s license.
3. Get your new trader bonus: Don’t miss out on the new user offers that most Connecticut prediction markets offer. Check whether the exchange requires the use of a promo code to obtain the bonus.
4. Fund your account: You can’t trade without funds to buy into markets, and you need to establish a payment source as another form of identity verification. ACH payments and debit cards are widely accepted, but some exchanges will also let you trade with particular cryptocurrencies.
5. Search the available markets: Locate the search function and simply type in what you’re interested in. If you can’t find what you’re looking for, check another exchange.
6. Claim your earnings: If you get a positive settlement from an accurate prediction or selling off your holdings, those funds are yours to withdraw as real money if you like. Pay attention to platform policies for withdrawal requests, especially differences in how long requests may take to process depending on the selection of various payment methods.

Example: Trading Connecticut Huskies women’s basketball futures

Currently, Kalshi offers a market on whether any NCAA D1 women’s basketball team will post an undefeated regular season for the 2026-27 campaign. Contracts on UConn in that market are priced at $0.21 on the “yes” side of that market and $0.88 on the “no” side.

People in CT can buy into either side or both. If you choose to do so, another user takes the opposite side of the market against you.

Contracts on the yes side settle positively if the Huskies finish their 2026-27 regular-season schedule without losing a game. Contracts on the no side settle positively if UConn finishes its 2026-27 regular-season schedule with at least one loss.

The amount on either side for positive settlements is $1. The amount on either side for negative settlements is $0.

That means if you bought into the “yes” side at the current price and the Huskies went undefeated, you would get a profit of $0.79 per contract, as $1.00-$0.21 is $0.79. Conversely, if you bought into the “no” side at the current price and UConn dropped at least one game, you would profit $0.12 per contract because $1.00-$0.88 is $0.12.

People in this market in CT wouldn’t have to wait until the regular season ends to sell off their positions in part or in whole, though. They could choose to do that well before the season ends if they wish, and there could be good reason to do so depending on the development of events.

As a hypothetical, imagine that the Huskies won their first five games of the season, making people more interested in this market. The price on the contract would escalate as a result of that increased interest.

Should the contract price on the yes side elevate to $0.41, for instance, people who bought yes contracts at $0.21 could sell and get a profit of $0.20 per contract. They would be giving up $0.59 per contract in potential profit compared to waiting it out, but they also greatly reduce their risk of not making any profit whatsoever on their position by enduring the long season.

How fees work

Connecticut prediction markets don’t have an interest in the settlement of users’ contracts, so fees are how they make money. When you make an accurate prConnecticut prediction markets don’t have an interest in the settlement of users’ contracts, so fees are how they make money. When you make an accurate prediction, your settlement money doesn’t come from the platform; it comes from the person who took the other side of the contract against you.

Fees vary by platform and by contract price. Check each platform’s fee schedule before you trade, since the rules aren’t the same everywhere.

Fees are typically highest on contracts trading near the middle of the price range and taper off toward the extremes. A contract priced near $0.50 reflects the most uncertainty, so exchanges charge more to facilitate that trade; a contract priced near $0.10 or $0.90 reflects a market that has largely made up its mind, so the fee is smaller.

That structure matters more than it looks. Fees are typically assessed as a small percentage of the contract’s price rather than a flat percentage of your total spend, so the profit margin they eat into shifts depending on where you’re trading. A contract on Tong’s reelection at $0.10 has far more room to run if you’re right than one at $0.60 — but a small fee still claims a larger share of that bigger potential profit.

Run your own numbers with DeFi Rate’s fee calculator before you trade, especially on lower-priced, longer-odds contracts where fees have the most room to cut into your upside.

Upcoming sports events to trade on in Connecticut

There are few greater hotbeds for collegiate sports than CT, especially in regard to men’s and women’s basketball due to the outstanding legacy the Huskies carry. These sports provide a stellar example of how the ups and downs of real-world events have drastic and immediate impacts on related contract markets.

People in CT who pay attention to headlines and act quickly can capitalize on opportune moments. For instance, if the Butler and Creighton men’s basketball teams suffer significant injuries, that could make prices rise on contracts related to the Huskies’ fates in that sport, and provide chances for people already in those markets to turn a quick profit.

CT prediction markets vs. sports betting

Because people in Connecticut have had over five years to enjoy online sportsbooks, they may mistakenly confuse sports event contract trading with traditional sports wagering. There are five important differences between these activities.

• Cost: Sportsbooks add “vig” into their lines while prediction markets extract fees from users.
• Flexibility: CT sportsbooks tend to restrict early cash-out options for bets in comparison to the opportunities that prediction market users get to sell their positions.
• Pricing: Bookmakers set the lines on sportsbooks while traders establish contract prices with demand.
• Regulation: Gambling is overseen by the Connecticut Department of Consumer Protection (CDCP) while the US CFTC oversees prediction markets.
• Structure: The book is your adversary in traditional sports bets, while other traders are your adversary in event contracts.

Among these five points of differentiation, the most substantial for people in CT is the amount of influence that users have on the availability and pricing of event contracts.

What markets can you trade on in Connecticut?

The evolution of CT prediction markets has produced six categories that most contracts fall into. These markets can have relevance on a global, local, and national scale.

Connecticut-specific rules for prediction markets

People in CT need to heed nationwide regulations that the CFTC imposes on prediction market trading, like age minimums and bans on insider trading. There are additional concerns for people in Connecticut because of the state’s challenge of sports event contract trading, though.

There is currently no court order affecting restrictions on those offerings from CT prediction markets, but litigation could change that any day. Platforms like Kalshi, OG Predictions, and Polymarket may reduce or remove their sports offerings in response to litigation.

CFTC rules have established a minimum age of 18 to trade event contracts, and Connecticut authorities are not challenging that standard. Neither the Connecticut Department of Revenue Services nor the US IRS has released specific guidance for earnings on prediction markets so far.

Connecticuters should assume that their earnings are taxable in that absence. The best course of action is keeping records of trading and consulting a tax professional in the state

How Connecticut works between products

The CFTC’s rules are intentionally vague in some regards to allow each exchange operator to determine policies that work best for its business and users. Two primary examples of the facets in which platforms set their own policies are market availability and settlement rules.

In CT, DKeX and FanDuel Predicts have foregone offering sports event contracts. Flutter CEO Peter Jackson pointed to the reason for these decisions as the desire to preserve the good standing of their gambling licenses in places like CT.

Exchanges use different sources as final authorities to settle markets. For example, some exchanges use statistics provided by third parties to resolve sports contracts while others rely on sport governing bodies directly to provide confirmation.

Prediction markets continue to evolve

User demand has significant influence on Connecticut prediction markets, but litigation involving event contract trading in CT is another factor shaping the present and future of the activity. There are several cases involving Connecticut officials, or that could have ramifications in the state.

At the time of this writing, CT Attorney General William Tong is leading a lawsuit against Kalshi challenging the legality of trading sports event contracts on that exchange in Connecticut. That case, while originally filed in the Connecticut Superior Court, has been removed to the US District Court for the District of Connecticut.

Tong is also among the defendants in a lawsuit that Kalshi filed in December 2025 in response to the CDCP demanding that it stop offering sports event contracts in the state. The US District Court for the District of Connecticut denied Kalshi’s request for a preliminary injunction barring enforcement of that order, but Kalshi has appealed that decision to the US Second Circuit Court of Appeals.

The CFTC also sued Tong in April 2026. A ruling on the CFTC’s request for an injunction against Tong and other officials is pending right now.

Finally, New Jersey authorities have now petitioned the US Supreme Court to review the US Third Circuit Court of Appeals’ decision upholding an injunction against them. A ruling by that court would have implications across the country, including in CT.
