Online sports gambling reached $10.99 million in the month of March via the Grand Traverse Band of Ottawa & Chippewa Indians, more than double what was wagered in February, according to data from the Michigan Gaming Control Board. The record amount was despite the fact that the Super Bowl -- traditionally the biggest sports betting event of the year -- took place in February.

Online sports gambling became legal in Michigan earlier this year. The Grand Traverse Band began its online gaming operations on January 22 with its partner, William Hill US, an international gaming company. 

The Grand Traverse Band made $1.03 million in gross receipts from that amount wagered in March, and adjusted gross receipts of $127,114 for the month after promotions and other costs. 

Tribal gaming operators in Michigan pay an 8.4 percent tax to the state based on adjusted gross sports betting receipts, meaning The Grand Traverse Band made a $10,667 payment to the State of Michigan for March.
