Sports betting has existed for centuries, evolving from underground bookmaking rings to highly regulated, billion-dollar global markets. While most bettors focus on odds, lines, and matchups, the industry’s history is filled with scandals that exposed corruption, greed, and the dark side of wagering.
Some of these scandals changed how leagues operate. Others reshaped betting regulations worldwide. All of them served as stark reminders that when money and competition collide, temptation follows.
Below are the top 10 sports betting scandals that shook the sports world and left lasting impacts on leagues, bettors, and bookmakers alike.
1. The 1919 Black Sox Scandal (MLB)
Sport: Baseball
Year: 1919
Impact Level: Industry-defining
The most infamous betting scandal in sports history remains the 1919 World Series, when eight Chicago White Sox players conspired with gamblers to intentionally lose the championship against the Cincinnati Reds.
Led by gambler Arnold Rothstein, the players accepted bribes to throw games. Despite being acquitted in court, all eight players were banned from baseball for life by Commissioner Kenesaw Mountain Landis.

Sport: Baseball
Year: 1989
Impact Level: Legendary downfall
Pete Rose, MLB’s all-time hits leader, admitted to betting on baseball games while managing the Cincinnati Reds — including games involving his own team.
Although Rose claimed he never bet against his team, the damage was done. He received a permanent ban from baseball, making him ineligible for the Hall of Fame.
Why It Rocked Betting:

Modern sports betting may be more transparent than ever, but these scandals prove that integrity must be actively protected — not assumed.

Sports betting scandals are a dark but essential part of the industry’s history. They expose vulnerabilities, reshape rules, and ultimately help build stronger systems.
For bettors, understanding these scandals isn’t just about history — it’s about recognizing why rules exist, why limits are set, and why integrity matters.
Because when trust disappears, the game itself is already lost.
