The head of the Massachusetts Gaming Commission is warning against potential “significant impacts” that could stem from issuing an uncapped number of temporary mobile sports wagering licenses, saying that the majority of those operators will be forced to shut down within a year.

Under the new state law, the number of mobile/online operator licenses untethered to a casino or simulcast is capped at seven, but no limits have been placed on temporary licenses.

“It is possible that no less than 30 entities will be competing for up to seven ultimate untethered category 3 licenses,” Gaming Commission Executive Director Karen Wells said.

Allowing temporary sports betting operations before a final determination is made on their full licenses poses financial complications for regulators, operators and customers, and also presents consumer protection concerns for the public, she said.
