Massachusetts Sports Betting Sites

There are eight Massachusetts sports betting sites. Each accepts wagers from players anywhere in the state who are at least 21 years old.

  • ESPN Bet
  • BetMGM
  • Betr
  • Caesars
  • DraftKings
  • Fanatics
  • FanDuel
  • WynnBet

Bally Bet and Betway are licensed to operate in Massachusetts. However, neither betting site operates there.

The Massachusetts Gaming Commission is the regulatory body for the state’s sports betting industry. It handles all aspects of the licensing and enforcement process. This includes vetting all key employees, sports betting companies, and vendors like software providers, geolocation tools, and marketing affiliates.

The Massachusetts Gaming Commission audits the financials of the state’s sports betting sites while collecting licensing fees and taxes. It also intervenes in player disputes related to support issues, bet grading, and payment processing.

Offshore sportsbooks still accept Massachusetts players. Some even claim they are legal when no license has been issued. There is too much risk in playing at these sites now that sports betting is legal in Massachusetts. If you have a dispute with a company based in the Caribbean or Central America, there is nothing you can do. These online sportsbooks have no gaming commission like Massachusetts has to mediate your dispute.

Massachusetts Sports Betting Bonuses

Massachusetts sports betting sites offer bonuses to new players. If you have an account with the company in another state or played daily fantasy sports contests with DraftKings or FanDuel in the past, you may not receive a first deposit bonus. This is true even if you last played there years ago.

There are three types of standard bonuses available at Massachusetts sports betting sites. Players may only receive one, even if multiple promotions are available.

Bonus Bet Loss Rebates

Most Massachusetts sports betting site bonuses involve a loss rebate. This is paid in the form of a bonus bet. This amount may be as small as $250 or as large as $1500.

If your first bet wins during a loss rebate promotion, you keep the winnings as normal. If your first bet loses, it is replaced with a bonus bet. This wager usually expires in a week or less. Some sites require it to be bet all at once, while others permit the player to break it up into multiple wagers. The terms and conditions of the site’s bonus disclose how it works.

Deposit Match Bonuses

A deposit match bonus is worded with a percentage and an amount of money. A common one available is 20% up to $1000. This means a player receives a bonus of 20% of the deposit. The maximum available bonus is $1000, which requires a $5000 deposit. Players can also deposit much less, depending on the size of their bankroll.

Deposit match bonuses have an attached wagering requirement. The number is usually higher than loss rebates. A general rule is the larger the maximum bonus amount, the more wagering required to clear it. In some instances, the deposit and bonus must be wagered, while in others, only the bonus is included.

Since these bonuses and wagering requirements tend to be large, players usually have months to meet the terms and conditions. It can be 60, 90, or 120 days.

Bet and Get Bonuses

The other common type of Massachusetts sports betting site bonus is when a small wager is made and rewarded with a larger credit. An example is “Bet $10, Get $200.” These offers are usually tied to major events. Larger promotions like deposit matches and loss rebates typically remain available when these smaller ones are advertised.

The bonus bet tied to this type of offer must be wagered quickly. The expiration is usually just a few days. It must be bet all at once. The wagering requirement is typically equal to the bonus.
