If I still remember how to do maths, 1% of $5 billion amounts to a potential $50 million the NBA could collect from 1% of sports bets made on NBA games. Gambling legalization in the united states is an interesting topic at the moment. Partly due to President Donald Trump publicly stating he would be in favor of legalizing it. There are old rumors of Trump trying to open a gambling casino in florida and being denied due to laws and regulation.
Donald Trump being a real estate mogul, he likely owns or has access to prime real estate in areas where casinos might be built. In his case, it may be a money making opportunity. In addiction, there could be a definite economic boost in terms of jobs created, tourism and similar advantages. The main naysayer of legalized gambling are Las Vegas casino owners who want to hold as much of a monopoly over gambling in the USA as possible.
