Indiana commercial casinos channeled their inner soothsayers as they predict a bleak future for the Hoosier State with the opening of Four Winds Casino South Bend.

Citing the findings of Spectrum Gaming Group, The Associated Press reported that Indiana’s tax revenues will drop by more than $350 million in its first five years once South Bend casino open in 2018.

Casino Association of Indiana, which represents most of Indiana’s commercial casinos, commissioned the report to determine the impact of the Four Winds Casino South Bend that’s being developed by the Pokagon Band of Potawatomi Indians.

Spectrum’s analysis found that the tribal casino, which is expected to roll-out the red carpet in early 2018, could cost Indiana’s 11 riverboat casinos and its two horse track casinos more than $800 million in gambling revenue over its first five years of operation by siphoning away some of their customers.
