What is moneyline in sports betting?
By DeepChamp research team · Updated · Methods and limitations
Definition
A moneyline is a wager on which side wins a game outright, with no point spread involved. The favorite carries negative American odds, such as -160, showing the stake needed to win 100, while the underdog carries positive odds, such as +140, showing the profit on a 100 stake.
How it works
Because there is no handicap, the price carries all the difference between the sides. A strong favorite pays little per dollar risked and an underdog pays more. Negative odds say how much must be risked to win 100; positive odds say how much is won on a 100 stake. Either can be converted to decimal odds or to a break-even probability, which is the chance the side needs for the wager to break even over time.
Overtime and ties are where terms differ. In sports that always produce a winner, such as basketball, hockey and baseball, overtime, extra innings and shootouts decide the moneyline. Football games can end level, and a tied moneyline is commonly voided or settled by the operator's stated rule. A soccer three-way moneyline is a different market that settles on regulation time and stoppage time and adds the draw as an outcome.
The two prices on a market add up to more than 100 percent when converted to probabilities. That excess is the operator's margin. Removing it from both sides gives the no-vig price, a cleaner estimate of how the market sees the matchup before you compare it with your own view.
Hypothetical -160 and +140 moneyline
A favorite is -160 and the underdog is +140. A $160 stake on the favorite wins $100 in profit and returns $260, so the break-even probability is 61.54 percent (160 / 260). A $100 stake on the underdog wins $140 and returns $240, so its break-even is 41.67 percent (100 / 240). The two figures add to 103.21 percent; the extra 3.21 percentage points are the operator's margin. A $50 stake on the favorite would win $31.25.
Hypothetical numbers for arithmetic only.
Why it matters when you research a bet
The moneyline looks like the simplest market, yet the price already contains the market's view of the favorite, so naming the likely winner is not the question. What matters is whether the probability implied by the price is higher or lower than a defensible estimate, and what the rules say about ties and overtime.
Common mistakes
- Treating a favorite as safe because it wins often. The price is already high to reflect that, so the question is whether the price is fair, not whether the favorite wins.
- Comparing profit across different stakes. A favorite's $100 profit needs a bigger stake than an underdog's, so compare break-even probabilities.
- Skipping the tie and overtime rules. A football tie, a soccer draw and a shortened baseball game can each settle a moneyline differently from what you expect.
Common questions
How do you convert a moneyline price into a break-even probability?
For negative odds, divide the amount risked by that amount plus 100. For positive odds, divide 100 by the odds plus 100. So -160 gives 160 / 260 and +140 gives 100 / 240.
Is a moneyline bet just picking the winner of the game?
Mostly, yes, but the price and the rules shape it. The odds reflect how likely the market thinks each side is, and settlement terms decide ties, overtime and shortened games, so the same result may not settle the same way at every operator.
