The Massachusetts Gaming Commission has issued a letter to the operators that have sports wagering licenses within the state, as they warn against prediction markets as it fights a lawsuit against Kalshi.
In a letter reviewed by ReadWrite, the organization says it is “aware that several Massachusetts sports wagering licensees are considering or have begun the process of partnering with entities in the prediction market space to begin offering event wagering contracts.”
The Massachusetts Gaming Commission informed each licensed sports wagering operator today that offering sports-related event contracts in the Commonwealth is prohibited.

Those who hold licenses for this purpose in the north-eastern state have been authorized for sports wagering which the commission says is defined as “‘sports event’ or ‘sporting event’ as a “professional sport or athletic event, collegiate sport or athletic event, a collegiate tournament, motor race event, electronic sports event or other event authorized by the Commission…”
The letter, which was issued on November 13, is to be taken as ‘notice’ that the license holders are prohibited from offering sports-related event contracts in the state, whether that’s directly or via an affiliate, related business entity, or other association.
It comes on the heels of Nevada intensifying its crackdown on the platforms, pulling key licenses from major operators DraftKings and Flutter Entertainment. Last month, Illinois also reconfirmed its position on prediction markets telling gaming licensees in the state that getting into prediction markets could impact its suitability.
Massachusetts letter is latest in back-and-forth about prediction markets
These sports-related event contracts have caused controversy up and down the United States, despite the popularity of platforms like Polymarket and Kalshi. While some states are warning against them, some companies are starting to partner up with them.
Just this week, the UFC announced a multi-year partnership with Polymarket as the prediction market is to become the sports official and exclusive prediction market partner. Also, earlier in November, it became clear that gambling giant FanDuel would enter the world through its new app FanDuel Predicts.
The letter continued: “In the event you offer sports-related event contracts in Massachusetts or direct patrons to such event contracts being offered in Massachusetts, the Commission may take steps up to and including revocation of your license. In addition, to the extent any other regulator takes action against your license due to your operation in the prediction market space, such action may inform decisions related to your suitability in Massachusetts.”
