How moneylines work
Moneyline odds use the American format. A favorite at -150 means risk $150 to win $100. An underdog at +150 means risk $100 to win $150. The numbers can be larger (-1000 for huge favorites, +1500 for big underdogs).
When to bet moneyline
Moneylines work best when you have a strong opinion about the winner but no view on margin. They're especially valuable on baseball, hockey, soccer, MMA, and tennis — sports where margin of victory varies enormously and a spread doesn't add structure.
Moneyline strategy
Look for value at +120 to +200 — underdogs in this range historically outperform their implied probability when chosen well. Avoid heavy favorites at -300 or beyond unless you have specific edge — the risk-reward is poor.
Use the calculator
Convert moneyline odds to implied probability with our odds converter. -150 implies a 60% win rate; +150 implies 40%. Find spots where you believe the true probability exceeds the implied probability — that's where +EV bets live.
