A huge week for Massachusetts
While Massachusetts sports betting revenue was up year-over-year but down relative to recent months, casinos took a step back in December.
The state’s three locations, Encore Boston Harbor, MGM Springfield, and Plainridge Park Casinos, combined to produce $97.9 million in gross gaming revenue across table games and slot machines. That was down 0.8% on the total reported in November and ranked fifth-lowest in 2025.
Massachusetts still has one of the largest gaming markets in America, and it just scored a huge legal victory.
On Tuesday, a judge granted a temporary injunction against Kalshi, allowing the state to block the prediction platform’s sports event contracts. This is the most significant victory for state officials, many of whom have argued across the country that event contracts act as betting odds without requiring their operators to receive the necessary licensing.
