Illegal Gambling

How big is illegal gambling? It may run as high as $100 billion per year. Other estimates put the figure even higher. That may seem like a very large figure, but as noted earlier, sports betting is immensely popular and most of it is illegal. The large extent of illegal sports betting is one of the reasons that some used to advocate its legalization. Others claim that business with illegal bookies would not decline 

because they offer better odds, credit, tax free payouts, and greater convenience in placing bets and collecting winnings.

Sports books are not the only component of illegal gambling. In San Jose, police raids led to the confiscation of 60 illegal slot machines at 14 different business establishments.
