Betting the moneyline is the most basic wager you can make when betting on sports. Here we will answer the question as to what is a moneyline bet. The sports betting experts at TheLines will also provide examples of this type of sports betting.
This is different from spread betting, which uses a handicap to theoretically level the odds on both sides. All the bettor’s selection must do is win and the moneyline bet pays out.
The moneyline bet remains the simplest sort of wager in theory, but there are still some intricacies involved. View moneyline odds for upcoming NFL games and find more information on how to place an ML wager below.
Moneyline
Here are the latest NFL moneyline odds available to bet on. These are the latest odds.
A moneyline bet simply wagers that one team or player will defeat another. Bettors also wager on the moneyline when they bet on an individual athlete, like a tennis player, to win their match. When it comes to ML betting on sports, you simply pick a side to win.
This differs from spread betting, which uses a handicap to theoretically level the odds on both sides. All the bettor’s selection must do is win, and the moneyline bet pays out.
Once the game or match ends, the sportsbook grades a bet one of three ways:
- Win – The selected team won. The sportsbook returns the stake plus the winnings.
- Loss – The selected team lost. The sportsbook keeps the stake.
- Draw – The game or game segment (half, quarter, period etc.) ended in a tie. The sportsbook returns the stake and it’s like the bet never happened.
Moneyline odds
Here is an example of moneyline odds for the upcoming NFL season. Keep in mind sportsbooks set the opening odds months before teams even report for training camp.
Tampa Bay Buccaneers +370 vs. Kansas City Chiefs -480
The NFL Week 9 MNF game is taking place at Arrowhead Stadium. Looking at MNF betting odds, the line above tells us, at least for now, that sportsbooks are considering Patrick Mahomes and the Kansas City Chiefs a heavy home favorite over the Tampa Bay Buccaneers.
Now, we’ll compare the potential moneyline payouts using a $100 bet as an example. Should you wager on the favored Chiefs being the outright winner, a winning ticket will pay $120.83, including a small profit of just $20.83. The implied odds for a KC win are nearly 83%. Even though the win probability would only be about 21%, other bettors might be tempted to go with the Buccaneers because of the “+” odds. Using the same $100 example, the payout on a winning New York bet would be $470.00, including a profit of $370.00. Before finalizing your moneyline bet, check out the current odds available at the top sports betting sites listed above so you get the best available price currently available.
Here’s another example from the most recent Super Bowl.
San Francisco 49ers -130 vs. Kansas City Chiefs +110
Using NFL Super Bowl odds, we’ll take a closer look at Super Bowl 58 between the San Francisco 49ers and Kansas City Chiefs as a moneyline example. The Big Game took place at Allegiant Stadium, home of the Las Vegas Raiders. Even though the Chiefs were the defending champs, the moneyline or outright winner example above tells us the 49ers were a small favorite based on the negative odds or “-” before the number.
The easiest way to understand moneyline wagers is by using a $100 bet as an example. Say you thought the 49ers – the NFC champs – were going to win straight up. The total payout on a winning $100 wager would’ve been $176.92 ($76.92 profit plus the original $100 bet back). The AFC champion Chiefs, on the other hand, were getting “plus” money. Since Kansas City was a very small underdog, the same $100 bet paid $210.00, including a $110.00 profit, or a tad more than even money. The implied probability of a Kansas City win was 47.6% versus 56.5% for a San Francisco win.
How do moneyline bets work?
The payouts for the moneyline wagers vary depending on the respective competitors’ perceived strength in the betting market. It’s not as simple as betting good teams to beat bad teams because the payouts on the moneyline reflect the situation. That is, you’ll risk a lot to win a little, “laying” the sportsbook a price.
Different regions of the world use different odds formats. American odds use a “plus/minus” system based around $100 wagers.
The favored team is denoted with a minus sign, followed by a number. The number reflects the stake needed to win $100. So, -400 means you must wager $400 to win $100.
The underdog will have a plus sign with a number. This number reflects the potential winnings on a $100 stake. So, +400 means you would win $400 on a $100 wager.
Betting the Money line: Implied probability
Moneylines at a sportsbook represent more than just betting opportunities. They represent the current market expectation of a game.
In this way, even non-bettors can gain valuable information about event probabilities by tracking the betting market. Many fans would likely find it interesting to know their team had, say, a 20% chance to pull an upset over a favored team.
How do we figure out the implied probability from a moneyline? Substitute the absolute value of the American odds for “x” into these equations:
- Negative odds: x/(x+100)
- Positive odds: 100/(x+100)
Then, multiply the result by 100. In the above example, San Francisco has a 79.16% to beat Detroit while the Lions have a 25.64% chance of pulling the upset.
“Hang on,” you may be saying to yourself. “Those percentages add up to more than 100.”
Good eye. That brings us to:
How does the sportsbook earn money booking moneyline bets?
The difference in numbers represents the vigorish, commonly called the vig or the “juice” – what the bookmaker charges for accepting your action. A market with say – one team being +380 and the other team being -380 represents a fair market, one with no vig. The implied probabilities add up to 100. The bookmakers want to turn a profit, so they include some vig, outside of maybe a few promo offers that may happen every now and then.
To figure out how much vig is in a market, one must perform some simple math based on the moneylines offered. This page has more information about what is vig in sports betting. The gist of it is, to get the “true” implied probability from a line, one must divide the implied probability of the line by the total implied probabilities of all options in the market.
As a general rule, one should expect fairly low vig in moneyline markets compared to many other types of bets like props and futures. That is, moneylines are usually a bit more bettor-friendly.
How and why do moneyline odds change?
Moneylines begin when a market-setting sportsbook opens a line. Some basic Googling can tell you whether or not a book sets markets. Only a few do. Most often, a sportsbook simply copies lines from the market-setters, the books that accept high-limit wagers from sharp, winning players.
The typical lifespan of a moneyline goes something like this:
- Market-setting (sometimes known as sharp) sportsbook opens a market.
- Competitors copy and post the market.
- Everyone’s limits begin fairly low. The exact size depends on the book.
- As game time draws nearer, more and more information pours into the market. This information allows the books to sharpen the line, theoretically drawing it closer to its “true” odds.
- When the books become more confident in their numbers, they expand the limits. Again, most often the books follow the leads of the market setters with some small variation based on house risk.
- The line closes when the game begins. In theory, the closing line represents the most accurate picture of the probabilities in the event.
The key point here is the information flowing into the market. Information includes injuries, weather and other variables. It also includes bets.
Sportsbooks react to sharp players placing max wagers. Often, when a line moves, it means action from sharp players has come in. The sportsbook respects these opinions and shifts the line accordingly.
That brings us to:
Line shopping: How bettors should approach moneyline bets
When considering whether to bet a moneyline, one must figure out the implied market probability and determine where the bettor’s estimated probability stands in relation to that number.
For example, you think the 49ers have a greater than 80% of beating the Bears, there’s value there.
However, what if you could find the 49ers at -350 somewhere else? Now, the value you gain betting on the 49ers is even greater.
Line shopping, or checking the price at numerous different sportsbooks, gives bettors the opportunity to search for the most profitable wager possible in the market. You know you’re going to bet the 49ers, but instead of just accepting the -380 that DraftKings sells you, check every other outlet to see if they will deal you a better price.
It may not seem like a huge deal to pay -380 versus -350. If you’re playing for $100, that’s a $30 difference. Sure, nobody would refuse $30 someone handed them, but it wouldn’t change most people’s lives.
But add that $30 up many times over hundreds to thousands of bets and you start to see the long-term difference it makes to your bottom line.
Should I bet the moneyline?
Generally speaking, the moneyline is a pretty good option for bettors who are betting with new sportsbooks. They are an intuitive and easy way to understand the market for novices. If your selected team or athlete wins, you win. Betting doesn’t get any easier to understand than that.
Perhaps most importantly, the bookmaker typically takes a fairly low vig, as noted above. Betting into low-vig markets is a best practice for sports bettors no matter whether they play for fun or for profit.
Second, it’s easy for bettors to figure out if a bet meets their value threshold. Simply convert the moneyline into the implied probability and use your judgment about how that number relates to your own estimate.
Finally, betting the moneyline aligns the team or athlete’s interest with your own interest. A very common NFL scenario illustrates this best.
Imagine a team trails 24-20 on the final drive of the game, but they’ve advanced to the opposing 20-yard line where it’s fourth down. They closed as +3 underdogs.
If the team’s goal was to cover the spread, they would obviously kick a field goal. But, the spread is irrelevant to the team’s goal. They want to win the game. They’re either going to score a touchdown and win the game, or they’re going to lose and fail to cover the spread.
In this case, having a wager on the moneyline would be far more appealing. If the team scores and wins, you get something like +140 on your money instead of having laid -110 to get three points that have ultimately wound up meaningless.
What about moneyline bet parlays?
Many fans love betting parlays. After all, they usually offer a much larger return than a straight bet.
And parlays can be fine. But, usually, they aren’t a great option. That’s because most bettors have a negative expected value (-EV) on their wagers. And for a parlay to have a +EV, most if not all of the bets in the parlay must have a +EV.
Makes sense, right? Link a bunch of winning bets together, and they win more money.
Most bettors can’t clear that bar, so parlays simply hand the house money at a faster rate since the bettor compounds their chance of losing. They should stay away from parlays until they gain more experience and become confident they have a positive expectation.
An exception comes from correlated parlays. These bets link two or more correlated events – that is, the likelihood of one leg of the parlay hitting increases the likelihood of another. The simplest example would be parlaying a favored, high-scoring team’s moneyline with the over on the game’s total. If the team performs well, they will likely score many points, which in turn increases their chances of winning the game.
Most sportsbooks have blocks in place to prevent bettors placing very obviously correlated parlays – something like Patrick Mahomes over 3.5 touchdowns with the Chiefs’ team total over.
However, same-game parlays have become something of a marketing gimmick at a few American sportsbooks. They have gained popularity thanks to huge winning bets going viral on social media. As long as the books allow them, bettors can take advantage of rare +EV parlays.

Moneylines and live betting
Live betting has become increasingly popular as technology has improved over the years. The increased speed of the bookmakers’ tech has enabled them to post in-game lines ever more quickly and efficiently. That gives the bettor more options to find value or even arbitrage and middling opportunities – that’s another post for another time.
Typically during breaks in the action, sports betting sites and the top betting apps will post in-game lines. They usually include a moneyline among the markets.
Live betting can offer bettors a great opportunity because the sportsbook doesn’t have as much time or information to produce a sharp line. To compensate for this, they’ll often include more vig than usual in the lines. Be aware of this when looking for live betting value on the moneyline.
Why was my moneyline bet canceled?
Spread betting often results in the stake being returned to the bettor when the game lands exactly on the spread, known as a “push.” Of course, this only becomes possible on even spreads like +6 as opposed to +6.5.
With moneyline betting, this scenario is far less common, but it can happen sometimes that your bet pushes or gets canceled.
The most obvious example comes from tied games. In certain sports, like NFL football, ties are possible. A bet on the moneyline will be returned if a game ends tied.
Note that in soccer, where ties are quite common, books usually offer three-way markets – each team to win or a draw. If you bet into these three-way markets (which usually only include regulation), understand that your bet grades as a loss if the game draws.
Other scenarios can result in canceled bets. Most baseball bets default to “pitchers listed,” which means the bet get canceled if the listed pitchers don’t throw the first pitch for their teams. Late scratches are not unusual in baseball since pitchers tend to be fragile creatures and teams must look out for their health. If either team switches its starting pitcher late, your bet may be canceled.
Another situation that may lead to canceled bets is when games end early or don’t play on the scheduled day because of a weather disruption. Consult your sportsbook’s house rules, as there’s often a minimum inning threshold that will result in action. But, these situations very often lead to canceled bets.
