Why Do Sports Betting Odds Change? Line Movement Explained

Let’s go back to our Yankees vs. Red Sox example and assume the sportsbook initially set the odds for the Yankees to win at -200. If a large number of bettors place wagers on the Yankees to win, the sportsbook might be forced to adjust the odds in order to balance the money wagered on each side of the bet. Every day we post the most lopsided games in terms of number of bets and percentage of bets. The contrarian betting strategy takes advantage of over-shaded lines and greedy sportsbooks.

They don’t win every bet, but that means it’s likely a good bet to place. See in one quick view which side the sharp money’s on and which games are the most lopsided in both tickets and money. Plus you’ll also see which games have the biggest difference between percentage of tickets and percentage of money – a surefire way to track the sharp action. Evaluating how the line moves throughout the week is a great way to determine where the money is falling. Watching line movement with live betting is another way to ramp up the action, as the MLB odds are constantly shifting during the game through in-play wagering. Finding the best MLB odds is step one to turning consistent profits betting on baseball.

Key numbers are important to watch out for when looking for middle bets since they can be very influential in the final result. So now you have separate bets on the Patriots -4 and the Chargers at +7. This leaves you in a situation where you will win both bets if the Patriots win by 5 or 6 points. If this happens, you will have a $200-dollar profit from both bets, despite betting on opposite sides. First, we’ll think about how the line movement affects our bets when we already know who we want to bet on.

Reverse line movement is when the line moves in contradiction to the public betting percentage. That is, even though most people are betting on one side, the line moves to make that side more attractive. Another possibility, particularly when the line moves erratically or unexpectedly, is that a lot of money has been placed by a small number of bettors. In the example above, the Chiefs started out as favorites and attracted a lot of bets. This would have made the sportsbook concerned that they would lose money if the Chiefs won.

Tracking line movement

This looks slightly different from our previous examples but the principle is exactly the same. While the 1.5 spread remains the same, the odds move in response to a lot of money being bet on one side. The runline is a popular form of betting in MLB, which is like a cross between point spread betting and money line betting. A runline bet involves a 1.5 run spread, accompanied by odds expressed in the same way as the money line.

Deepening on the patterns of change, line movement can tell you a lot about how the general public is leaning, and how the sharp money is leaning. As a comparatively low scoring game, point spread betting in NHL is less common than in NFL or NBA. This affects line movement when it comes to NHL totals bets too, which are less likely to move as much as the other sports. Key numbers are less influential in betting on basketball, but they do exist. Furthermore, sportsbooks are likely to not worry about those numbers when they move the spread so they are easier to pick up.

At any rate, market forces can influence sportsbook odds as the sportsbook adjusts the odds in response to the amount of money wagered on each side of the bet. The odds for a particular event can change based on the amount of betting activity and the expectations for the outcome of the event. Sports betting is growing across the US thanks to the recent Supreme Court decision, and more states are moving towards legalization every day. Line movement most commonly occurs when the large majority of the money in a bet is on one side.
