Best prediction market apps in Massachusetts

This guide compares the best prediction markets in Massachusetts, explains how they work and what you can trade, the best promo offers, and the regulatory landscape.

Are prediction markets legal in Massachusetts?

Yes, but there is ongoing litigation addressing that very question. United States law (the Commodity Exchange Act and the Dodd-Frank Act) permits prediction market trading on exchanges registered with the Commodity Futures Trading Commission (CFTC), but Massachusetts officials have disputed the legality of sports event contracts in the state.

Massachusetts Attorney General Andrea Joy Campbell sued Kalshi in state court over those sports event contracts in September 2025, arguing that they represented illegal gambling under the state’s Sports Wagering Act (Chapter 23N). In January 2026, the court granted Campbell’s request for an injunction banning Kalshi from offering sports event contracts to people in Massachusetts.

However, that injunction has been stayed pending Kalshi’s appeal to the Massachusetts Supreme Judicial Court. It’s important for people in Massachusetts to note that the dispute only involves sports event contracts, meaning that MA officials have not yet challenged the legality of non-sports prediction markets.

The Massachusetts Supreme Judicial Court will determine the status of sports event contracts in the state, and federal court cases around the United States will also impact the availability of these markets. For the time being, though, MA prediction markets face no legal restrictions on the types of contracts that they can offer.

MA prediction market apps reviewed

The following Massachusetts prediction markets are all registered with the CFTC and operate according to the CFTC’s regulations. However, each of these exchanges excels in certain aspects more than others, giving them value that makes them worthy of inclusion in a rotation for people in MA.

• Polymarket: Best for people looking for a high-value welcome bonus
• Kalshi: Best for traders who prioritize high market volume
• FanDuel Predicts: Best for traders who like to price shop
• OG Predictions: Best for people interested in cryptocurrency contracts
• DKeX: Best for people experienced with betting on sporting events

Polymarket US

Best for people looking for a high-value welcome bonus

Polymarket has the best sign-up bonus for traders in MA in terms of ease of access and value. Other exchanges like Kalshi maintain a trading requirement to receive the welcome bonus or offer a smaller bonus in terms of dollar value.

Polymarket also offers sports event contracts in MA, giving users the option to trade on contracts pertaining to New England Patriots and Revolution events. The market volume on Polymarket is rapidly growing, so these contracts are worth a look from people in Massachusetts.

Kalshi

Best for traders who prioritize high market volume

People in MA may find better volume on contracts connected to more emerging or niche events at Polymarket, but Kalshi tops all of the exchanges on this list in terms of consistently posting high market volume on contracts for big events in the news or popular cultural touchpoints. Kalshi is also one of the only two operators on this list that currently offers sports event contracts in Massachusetts as of the time of this writing.

That means traders in MA can buy into contracts on events like Boston Bruins, Celtics, Fleet, Legacy FC, and Red Sox games. There are also tangential markets like whether those teams will qualify for the postseason or individuals with the organizations will win awards.

FanDuel

Best for traders who like to price shop

FanDuel has built its exchange with an emphasis on displaying contract prices in multiple formats, making it easy for traders to do price comparisons in a medium that they understand, like dollar amounts, percentages, and even American odds that will be familiar to MA sports bettors. At the same time, FanDuel Predicts does not currently offer sports event contracts in MA.

Bay Staters can still find plenty of markets with local relevance, especially in terms of politics. FanDuel Predicts offers several contracts connected to the 2026 Massachusetts governor election, as just one example.

OG Predictions

Best for people interested in cryptocurrency contracts

If cryptocurrency and unconventional financial products are of interest, there’s no better place to find a deeper volume of such markets than OG Predictions. The variety and volume of these contracts, like cryptocurrency price targets, is simply stronger than what you will find on any other exchange on this list because OG Predictions is a Crypto.com product.

OG Predictions does not give people in Massachusetts access to sports event contracts, but the politics offerings are robust, including markets like whether US Sen. Ed Markey will win reelection in November 2026. Traders in MA can also find mention markets for celebrities from Massachusetts like Conan O’Brien and Amy Poehler.

DraftKings

Best for people experienced with betting on sporting events

DraftKings designed DKeX to make it a seamless transition for traders familiar with DraftKings Sportsbook, with the appearance and function of the apps and website essentially identical. That similarity becomes less potent, though, when you consider that DKeX currently does not offer sports event contracts in MA.

Regardless, if you’re new to prediction market trading in MA and interested in things like whether the productions of Massachusetts stars like Ben Affleck or Mindy Kaling will get a good Rotten Tomatoes score, DKeX makes getting comfortable with that trading easy. The market volume at DKeX is also growing, so it’s worth keeping in your rotation for comparing prices on culture, news, and politics.

How to trade prediction markets in Massachusetts

Bay Staters who have signed up and bet on traditional online sportsbooks have already experienced most of the process of getting started with prediction market trading. The six steps necessary to begin moving in and out of contract positions are very similar.

1. Choose an exchange: All of the exchanges listed in this guide are CFTC-regulated and accept trades initiated by people in MA. Traders should still compare fees, market volume, and market selection to see whether the exchange fits their preferences.
2. Verify your account: Before you can start trading, you need to provide documentation of your age and identity and share contact information with the exchange.
3. Get your welcome bonus: Many exchanges automatically apply sign-up bonuses to new customers’ accounts, but some will require the use of a bonus or promo code to receive the welcome value.
4. Make your first deposit: Each platform maintains unique policies as to which forms of payment it accepts, like ACH payments, debit cards, or wire transfers. Some exchanges may accept certain cryptocurrencies as well.
5. Look for event contracts: Markets involve binary yes/no outcomes on events and range in price from $0.01 to $1. Traders can move in and out of these positions with great flexibility, so start with something that interests you. 
6. Get your earnings: If your predictions prove accurate, you will be paid according to the terms of the contract. You can visit the cashier section of the app or website to withdraw those funds, but pay attention to the differing processing times for the various methods of withdrawal. 

Example: Trading on New England Patriots futures

People in MA using Kalshi or Polymarket can find plenty of New England Patriots contracts for the 2026-27 season, including markets on the team’s regular-season win total.

At the time of this writing, the “yes” side of the Patriots winning at least 10 games during the 2026-27 season traded for $0.56 at Kalshi. If the Patriots complete the regular season with nine or fewer wins, that contract settles at $0, representing a loss for people in the market.

If the Patriots finish the season with at least 10 wins, the market settles at $1. That would mean a profit of $0.44 for each contract for people who bought in at $0.56.

Traders are not bound to wait out the contract settlement, though, and are free to take advantage of favorable fluctuations. For example, suppose that the Patriots get off to a hot start and win their first three regular season games, meaning they would only need to win half of their remaining 14 games to get to that 10-win threshold.

In that case, the contract price could rise to reflect the increased demand for the market. If it were to rise to $0.86, for example, people who bought in at $0.56 could sell at that point and realize a $0.30 profit. In doing so, they would sacrifice the other $0.14 of potential profit to get the guaranteed $0.30 in profit.

How fees work at MA prediction markets

Bay Staters interested in Patriots or Red Sox futures will find plenty of markets on MA prediction markets, but exchanges also charge fees that 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 at $0.10 has far more room to run if you’re right — a $0.90 payout on a winning $0.10 contract — but a small fee still claims a larger share of that bigger potential profit than the same fee would on a $0.60 contract with less room to climb.

Upcoming sports events to trade on in Massachusetts

Kalshi and Polymarket give people in MA an array of sports event contracts to choose from, centered on Boston-area athletes and teams. The prices on these contracts can move drastically in a short amount of time as news breaks, and traders can gain or lose confidence in outcomes.

As just one example, Kalshi offered at the time of this writing a market on Jayson Tatum’s next team, with the Boston Celtics trading in that market at $0.97. Relevant reports by members of the media, social media posts by Tatum or people close to him, and other transactions that the Celtics announce can make that price move down or up in a matter of minutes.

MA prediction markets vs. sports betting

Online sports betting in Massachusetts gives people opportunities to wager on a host of actions and events, and Bay Staters can also trade sports event contracts on Kalshi and Polymarket in MA. People in MA are best off understanding the differences in how these products work and why they may choose to trade sports event contracts or place traditional sports wagers.

• Cost: Sports betting includes the financial interest of the sportsbook in the line, whereas prediction markets charge fees.
• Flexibility: In general, people using prediction markets tend to experience greater flexibility in moving in and out of contract positions before the contract settles in comparison to cashing out a conventional sports wager early.
• Legality: Both prediction markets and sports bets are legal and regulated in MA, just by different bodies. The Massachusetts Gaming Commission regulates sports wagering while the CFTC oversees event contract trading.
• Pricing: Sportsbook operators set their lines according to their models and the vig in the bet, while with prediction markets, demand sets the price for event contracts.
• Structure: With sports bets, you’re wagering against the house. In prediction markets, your “opponent” is another trader.

While Massachusetts is challenging the legal status of sports event contracts in court, the biggest difference between prediction markets and sports wagers is the amount of influence that traders have on the price of the contracts.

What markets can you trade on in Massachusetts?

Event contracts at MA prediction markets cover almost everything of cultural significance and financial impact. The scope of the markets includes:

• Cryptocurrency: Make predictions on the prices of Bitcoin, Ethereum, and more. The best platform here is OG Predictions.
• Culture: Trade in everything from Rotten Tomatoes scores for movie releases to mention markets for celebrities’ social media accounts and reality television series developments. The best platform in this category is DKeX.
• Economics: Find contracts for Federal Reserve interest rate moves, job reports, and Consumer Price Index changes. The best platform for these markets is FanDuel Predicts.
• Politics: Whether it’s futures on the 2028 US presidential election or contracts for US Sen. Ed Markey’s margin of victory that intrigue you, there is plenty to browse. The best platform within this range is Polymarket. For the complete national race map and live odds, see our 2026 midterms page.
• Sports: Game markets as well as player awards, coaching moves, player transactions, and win totals are all among the possibilities for Boston and national events. The best platform for sports contracts in MA is Kalshi.

Massachusetts-specific rules for prediction markets

The CFTC regulates prediction markets in Massachusetts, not the Massachusetts Gaming Commission, which regulates sportsbooks. That means the regulations affecting MA prediction markets differ from the rules for gambling in the state.

For example, the minimum age to trade on prediction markets is 18, while Massachusetts law requires residents and visitors to be at least 21 years old to gamble. Additionally, prediction markets currently face no licensing requirements and pay no gambling tax in MA, although ongoing litigation could change that status quo.

Bay Staters familiar with sports wagering should also note that rules for settling event contracts are different from the policies that guide sports wagers. The big differences include that contract prices can fluctuate to a greater extent than sports bets, and traders have more flexibility to move in and out of positions in general.

One thing that both gambling and trading have in common in Massachusetts, though, is that earnings or winnings are generally taxable income under federal and state law. Bay Staters should keep detailed records of their activity and consult a tax professional to ensure accurate payment and reporting.

How Massachusetts works between products

Massachusetts has been home to legal online sportsbooks since 2023, and MA prediction markets are available alongside those sportsbooks. Massachusetts authorities are challenging the legality of sports event contracts on prediction market exchanges, but only sports event contracts.

Amid that litigation, which seeks to treat sports event contracts as identical to sports wagers under state law, several prediction market exchanges have foregone offering those contracts in MA. For example, Flutter CEO Peter Jackson stated that FanDuel wouldn’t do anything to harm its business in regard to offering sports event contracts in states where FanDuel has a sports wagering license like Massachusetts.

Kalshi and Polymarket do not have such licenses to try to protect, so they have instead gone the litigation route to preserve their ability to offer sports event contracts in MA. Ultimately, the courts will determine whether MA can regulate sports event contracts like sports bets.

Prediction markets continue to evolve

Massachusetts has been an active jurisdiction for the legal dispute over sports event contracts, featuring cases in federal and state courts. At the time of this writing, MA Attorney General Andrea Joy Campbell has secured a preliminary injunction barring prediction markets from offering sports event contracts in the state, but that injunction is not in effect pending an appeal by Kalshi.

While that stay of the injunction remains valid, prediction market activity remains solely under the supervision of the CFTC, and sports event contracts remain available on the exchanges that have chosen to offer them in MA. It’s important to note that Campbell has not challenged the legality of all prediction market trading, merely sports event contracts.

A successful appeal by Kalshi or a lifting of that stay could quickly change the status quo in terms of sports event contracts in MA. That resembles the state of prediction market trading, especially within the context of sports event contracts, across the greater nation.

The CFTC, exchanges, state governments, and tribal authorities have lodged several lawsuits across the nation disputing attempts to regulate event contract trading and the legality of such trading. Decisions on those issues by federal courts outside of MA, especially the US Supreme Court, will have an impact on Massachusetts prediction markets.

Things to know before you trade in Massachusetts

Bay Staters can trade on prediction markets of all types, and it’s good to keep a few things in mind as you do so.

• Different exchanges have different policies: CFTC rules let exchange operators set their own policies on what types of markets are available, the fee structure, and the payment methods they will accept.

• Sports event contract availability may change at any time: A decision from the Massachusetts Supreme Judicial Court remains pending following May 2026 oral arguments, and that ruling could put the injunction against sports event contracts into effect immediately while giving exchanges a matter of days or weeks to comply.
