Legal sports betting has exploded since the 2018 Supreme Court decision, now generating $150 billion annually, with apps like DraftKings and FanDuel making wagers accessible to millions. While prop bets deepen fan involvement, they also create incentives for manipulating individual plays. Scandals involving NBA figures Chauncey Billups and Terry Rozier, along with MLB pitchers Emmanuel Clase and Luis Ortiz, highlight vulnerabilities in oversight. Despite league efforts to monitor betting patterns and restrict risky markets, inconsistent regulations across states weaken enforcement. Athletes, especially younger or less-paid ones, face growing pressure from fans and financial temptations, increasing corruption risks. The sports world now grapples with balancing profitability against the long-term integrity of competition.
