Casinos argue allowing historical horse racing machines will harm business

By the Editorial Team · Thursday, October 22, 2026

Massachusetts’ top three casinos have jointly opposed a plan to introduce historical horse racing machines at former racetracks, warning these devices could cause significant revenue losses and job cuts at their existing properties. Their opposition has intensified a legislative dispute over the economic development bill, leaving the fate of the new gaming machines uncertain as lawmakers negotiate between expanding gaming options and protecting established casino interests.

Massachusetts’ three leading casinos have jointly opposed a proposal that would introduce historical horse racing machines at former racetracks, warning that the new gaming devices could significantly disrupt their business. The dispute has become a key issue in ongoing negotiations between the state House and Senate over a broader economic development bill.

The proposal, championed by developer Richard Fields, seeks to authorize machines that resemble slot machines but allow wagering on previously completed horse races. This gaming format is currently employed in New Hampshire, where it has supported a growing casino industry. Proponents argue that these machines fall under pari-mutuel betting regulations rather than casino gambling laws, potentially opening a new revenue stream at former racetrack venues.

House leaders included the historical horse racing provision in their version of the legislation, but Senate members have expressed reservations, leading to a legislative standoff. To bolster their opposition, operators Wynn Resorts, MGM, and Penn Entertainment commissioned two gambling consultants to assess the potential impact on their Massachusetts properties—Encore Boston Harbor, MGM Springfield, and Plainridge Park.

The consultants’ report warned of notable revenue declines for the existing casinos, estimating annual losses in state tax revenue ranging from $45 million to $73 million. It also forecasted employment reductions within the casinos numbering between 585 and 975 jobs due to anticipated decreased business. The three casino operators submitted these findings to legislators in a letter, advocating for the exclusion of the historical horse racing language from the final economic development bill, citing “adverse impacts” to both their operations and state finances.

Supporters of the proposal argue that the machines would diversify gaming options in Massachusetts and enhance economic activity at former racetrack locations. Critics, including the casinos, contend that the machines would cannibalize the established casino market rather than create net new economic growth.

As lawmakers work toward reconciling differences between the House and Senate versions of the bill, the future of historical horse racing machines in Massachusetts remains uncertain. The state faces balancing interests among established casino operators, new gaming ventures, and broader economic development goals amid the complex dynamics of the regional gaming market.
