Sports betting value is when the probability of an outcome differs from the posted odds. One of the most notable shifts in Super Bowl history came in 2015 between the Patriots and Seahawks. Seattle, the defending champion, opened as a 2.5-point favorite, but New England closed as a one-point favorite, a shift of 3.5 points. Bettors were right, though not until Malcom Butler pulled off an interception in the end zone to secure a 28-24 victory. It's never easy, as that frenzied final finish showed, but consistently winning bettors are constantly on the lookout for value.
Bookmaker vs. Bettors: Who Really Sets the Odds?
A constant battle is taking place between sportsbooks, public bettors, and professional gamblers. All can have differing opinions on what a betting line should be. And it's not just talk: they all back their opinions with real money. Public bettors are a large group that wager small amounts, while pro bettors are a small group that back their picks with larger sums of money. Sportsbooks take the action and adjust lines. Several factors, including the amount of money on each side, influence those adjustments.
Betting Value: Finding the Edge
Sports betting value is when the probability of an outcome is higher than the posted odds. Proposition wagers on pregame coin flips are -110 or -115. There is no betting value because the true odds are +100 (even), as a coin flip is 50/50. If some sportsbook had +105 on tails and -120 on heads, tails would offer positive expected value. Value is present on some point spreads. If your handicapping says a team should be a 7-point favorite or higher but the opening line is -5, you've identified value. It's even more common with totals, as less attention is paid to them with fewer dollars wagered. Sides often move one or two points, while totals can shift double that or more. A component of basic sports betting strategy is identifying mispriced odds and making a play before they move.
Shifting Odds: Why the Line Moves
There are two things that bookmakers make that bring betting value: mistakes and changing numbers. Mistakes are just that: overvaluing or undervaluing one team, making what should be a 6-point favorite to -7.5, for instance. Professional bettors make their own numbers and are ready to pounce on errors as soon as the odds are released. Numbers often change because the flow of money forces sportsbooks to shift their opening odds. This opens the door to value betting. In the Chiefs/Eagles Super Bowl, Kansas City opened as a 1.5-point favorite, but some early money by average bettors moved them to a 2-point favorite at some sportsbooks. However, professional sports gamblers then poured in sharp money, recognizing that the Eagles were a better team than the one that had lost to Kansas City two years earlier, 38-35, moving Kansas City to a one-point favorite.
Moneyline Value
Sometimes point spreads don't move, but the moneyline does. This is another sign for sharp betting eyes to discern which way the money is moving—and where value lies. The moneyline on the Chiefs/Eagles Super Bowl rematch saw Kansas City shift from -125 to -130. Then, as sharp money backed the underdog, the Eagles eventually closed at even money (+100) at some books. Bettors who moved swiftly got Philadelphia at +110 or +115, locking in the best value. The pros were spot on with the point spread and the moneyline, with the Eagles winning handily, 40-22.
Fading the Betting Public
Professional gamblers find betting value by using their heads. This requires analyzing matchups and situational factors to gauge what the point spread should be. In a sense, they're putting together what a reasonable final score is likely to be based on research. The average sports bettor, on the other hand, fails to do anything comparable. They're betting with their hearts or for fun. Super Bowl XLVIII between the Seahawks and Broncos was a classic example. The big game opened at "pick 'em," but 72% of the bets came in favoring the Broncos, moving Denver to a 2-point favorite. The public was enamored with the record-setting offense of the Broncos, while sophisticated bettors recognized that the great defense of the Seahawks was a greater Super Bowl edge. The public was wrong, and it wasn't even close, as Seattle rolled, 43-8. The Seahawks had a yardage advantage while winning the turnover battle 4-0. The No. 1 defense shut down the No. 1 offense, which is not uncommon. The betting public follows the oddsmakers, while pro bettors take the lead, making their own numbers ahead of the books.
Lose the Chase, Win the Race
Identifying and taking advantage of wagering value is an innovative, long-term approach to building your sports betting bankroll. It maximizes earnings and helps absorb the negative impact of the inevitable bad beats. One of the biggest mistakes non-professional gamblers make is chasing losses. A couple of games go against them, and they start wagering larger amounts in hopes of winning back what they just lost. For decades, Monday Night Football has seen massive amounts of action from bettors who had a bad Sunday, then hope to win it all back with one big play on MNF. This is a classic chase, putting good money after bad, and it's a mistake that will lead to the poorhouse. Don't chase. Money lost is not yours anymore. Stay calm and focused on the following slate of games.
Value Raises Your Game
Gambling on sports is a never-ending battle between oddsmakers, sportsbooks, and bettors. To find long-term success, you need to look at the bigger picture, and "value" is often what separates profits from losses. Pro gamblers play the long game, searching for betting value where the probability of an outcome differs from the posted number. Successful professional gamblers don't chase losses and aren't afraid to fade the public. By focusing on value, you're not just avoiding the common trap of chasing; you're building a sustainable strategy that grows your bankroll over time. Be on the lookout for soft lines, value with totals, and on the moneyline. In the end, luck swings back and forth, but value is the constant edge that gives disciplined bettors a long-term advantage.
