Massachusetts Online Sports Betting

Massachusetts Sports Betting

Sports betting has become a reality in Massachusetts with the first legal bets being placed in early 2023 at three retail casino sportsbooks. Online sportsbooks are expected to go live by the middle of March in time for March Madness.

Massachusetts visitors and residents already enjoyed the ability to play in casinos, buy lottery tickets and use OTB locations to bet on horse racing.

However, sports betting was not an option until Governor Charlie Baker signed the Massachusetts Sports Wagering Act into law in August 2022. 

It ended a long process for the state with sports betting bills passing one of the two legislative chambers on multiple occasions without reaching the governor’s desk.

In 2011, then-Governor Deval Patrick signed the Expanded Gaming Act which authorized three casino resorts and one stand-alone slots-facility. However, in the wake of sports betting being legalized nationwide, Massachusetts struggled to find the right terms to bring the option to the state.

Massachusttes sports betting falls under the jurisdiction of the Massachusetts Gaming Commission (MGC).

Given its role as an endeavor that developed rather recently (and therefore not touched by the legal quibbling of the past by all the major U.S. sporting leagues), eSports betting may lead the sports betting legalization way in Massachusetts just as it has done in other states.

What are eSports?

Blossoming with the dissemination of global technology and increasingly fast internet speeds, eSports has changed quality video game play into full-time professional sports, whereby leading players sign multi-million-dollar contracts with professional teams.

Team tournament play rather than individual competition is generally how eSports are played at their highest levels. However, champion individual eSports stars can have cult global followings and the contrasting styles of the top eSports athletes are loved and copied by amateur players the world over.

eSports games themselves like Fortnite, League of Legends and Overwatch are equivalent to, say, the NBA, NFL and MLB, with the phrase ‘eSports’ describing the broad overarching concept (like Sports). 

eSports betting has become widespread and a big global business. Sportsbooks worldwide offer betting markets on all major eSports tournaments played globally. eSports business revenue grows massively year-on-year, and in 2018-19, the revenue of the industry is expected to reach the $100 billion mark worldwide.

It may be possible that the initial legal sports bet you make in Massachusetts, could possibly be a wager on eSports.
