Brockton casino developers can open the first resort casino in Massachusetts.

Rush Street Gaming Chairman Neil Bluhm told the Massachusetts Gaming Commission (MGC) Thursday that it can build its $677m casino-resort complex in Brockton Fairgrounds, sooner than MGM and Wynn Resorts.

Mass Gaming & Entertainment, a subsidiary of Rush Street Gaming, is the lone applicant for last casino license in Massachusetts after New York-based developer KG Urban Enterprises abruptly dropped out from its proposed casino project in New Bredford. However, its chance to win the casino licensed has been complicated by pending resolution on the legal status of a casino proposal from the state’s federally recognized Mashpee Wampanoag Indian Tribe.

The tribe plans to build a $500m casino in Taunton, which, will be called the Project First Light. Although it does not need a casino license to build one, the tribe ae willing to have an agreement with the government and pay taxes.
