The sports betting explosion has unleashed a $500 billion monster that engulfs everything game its path. Since the Supreme Court opened the floodgates in 2018, betting and its betting apps bombard fans during every game, turning each play into another chance to wager.

States hungrily eye their cut while young men are scientifically targeted. Few understand this transformation better than my guest Jonathan D. Cohen, whose new book "Losing Big: America's Reckless Bet on Sports Gambling" takes us deep inside this revolution that happened so fast we barely had time to understand its implications.
