What is Implied Probability?

Implied probability is the win percentage that the sportsbook's odds suggest. It tells you how likely the book thinks an outcome is to happen.

Finding Value: If you believe a team has a 60% chance to win, but the implied probability is only 50%, you've found a value bet. The key to profitable betting is finding spots where your estimated probability exceeds the implied probability.

Responsible Gambling

Gambling should be entertaining, not a way to make money. Only bet what you can afford to lose, and never chase your losses.

Signs of problem gambling:
  • Betting more than you can afford to lose
  • Chasing losses with bigger bets
  • Lying to others about gambling habits
