States are increasingly pushing for the legalization of sports betting and it could present investors with a grand opportunity in 2020, Wall Street analysts think.

Pennsylvania made sports gambling legal in 2017. New Jersey joined Pennsylvania in June 2018. More recently, Michigan’s state government signed into law a series of bills that will allow residents to wager on sporting events next year.
