If you're placing your first sports bet, start here. A moneyline bet is the most straightforward wager in sports: you pick which team (or player) wins the game. No point spread, no margin of victory — just the winner.
How moneyline odds work
Moneyline odds tell you two things: who the sportsbook thinks will win (the favorite) and how much the bet pays.
Chiefs -180 (favorite)
Raiders +155 (underdog)
The minus sign means the Chiefs are expected to win. To profit $100 on the Chiefs, you'd risk $180. If you take the Raiders at +155, a $100 bet wins you $155.
The gap between the two prices is the vig. In a perfectly fair market, -180 and +180 would be the prices. But the sportsbook charges a margin, so the underdog gets +155 instead of +180. That difference is the book's profit.
Calculating moneyline payouts
Notice the risk/reward tradeoff. The favorite pays less because it wins more often. The underdog pays more because it wins less often. Neither is inherently better — what matters is whether the odds offer +EV.
Where beginners find +EV on moneylines
Underdogs are where the value hides. Public bettors overwhelmingly bet favorites — they feel "safe." This public bias can inflate the favorite's price and create value on the underdog side. That doesn't mean you blindly bet every underdog. It means you look harder at underdogs, because that's where the market is most likely to be wrong.
Small underdogs (+100 to +180) are the sweet spot. These are competitive games where either team can win. The market is close to a coin flip, but the underdog pays more than even money. If your research suggests the underdog's true probability of winning is even a few percentage points higher than the implied probability, you have a +EV bet.
Avoid heavy favorites for profit. Betting -300 or worse means risking $300 to win $100. You need to win 75% of these bets just to break even. One upset wipes out three wins. Heavy favorites are terrible for bankroll growth unless you have overwhelming evidence the line is wrong.
Moneyline vs. spread: when to use which
In close games (spreads under 3 points), the moneyline and spread are both viable options. The moneyline is simpler — your team just needs to win. The spread offers better payouts but adds the margin-of-victory requirement.
For bigger underdogs, the moneyline can be better than taking the points. If you think a +7 underdog has a real shot at winning outright, the moneyline at +280 might be more +EV than the spread at -110.
The bottom line: Moneyline bets are the simplest bet in sports — just pick the winner. Start here as a beginner, focus on small underdogs where public bias creates value, and always check whether the implied probability matches your estimate before placing the bet.
