Pictured: Lamar Jackson Patrick Mahomes When you look at futures odds for an event like the Super Bowl you see all 32 teams at plus-money and some at longshot prices. But just because youre getting greater than 6-1 on every team doesnt mean youre getting fair prices. Youre paying even more of a premium when betting most futures than you are for a single NFL game when the sportsbooks have a 4.8 hold. Baked into futures market is lots and lots of hold often greater than 30. Below well explain what hold is how to calculate hold on any futures market and how to remove it to get true probabilities. _BookPromo=7 What Is Hold? The actual hold percentage refers to the percentage of money that the house keeps for every dollar wagered. Nevada held 3.6 of all money wagered in August 2020. The theoretical hold is how much money the house would keep in a given market over an infinite amount of bets. More on this in a bit. As a bettor you want lower hold percentages. Books will profit more in the long run from higher hold percentages but will turn off customers if they have unfair holds relative to their competitors. Understanding Implied Probability To understand hold you need to first understand implied probability in sports betting. When you bet on a coin flip with your friend you each have 50/50 odds. That means the total probabilities of all the outcomes is 100. But when youre betting sports and convert odds to probabilities those probabilities will add up to more than 100. Thats because a sportsbook charges you a tax on every bet to take your action. So what is hold? Its really just the probability of all the outcomes an event minus 100. Whatever percentage is leftover is the hold. Here are some examples of hold for different sets of odds featuring two teams. The holds are relatively low for something like an NFL point spread less than 5. Calculating Hold on Futures On futures with many possible outcomes the hold is much higher. Using a simple formula in Excel or a Google Sheet you can calculate the hold for any futures. That way you can tell if your sportsbook if giving you a fair shake. All youre doing is converting each set of odds to probabilities and adding up the probabilities. Since the conversion is slightly different for positive numbers (like 120) and negative numbers (like -120) in American odds this equation will execute different formulas depending on what the odds are. =IF(Oddsgt;01/(Odds/1001)1/(1100/ABS(Odds))) Heres what it will look like in Excel or a Google Sheet. And below are the full probabilities after adding it all up we arrive at 133.03 meaning the sportsbook has a 33.03 hold on your wager here. Remember an NFL point spread at -110 on both sides is only 4.8. For league futures like the Super Bowl its common for books to hold between 20 and 30 because its harder to accurately price all the possible outcomes for something like the Super Bowl. Removing Hold Why should you remove hold? If youre making your own projections you want to see how they line up with a books probabilities to get your edge. Your first reaction might be to just knock 1 off every teams probability since the hold is 33 and there are 32 teams. But its notthatsimple. Thats because what seems like a small line move for one of the favorites might actually represent a bigger change in probability than a team falling from 100-1 to 50-1. For example the following shifts in odds are roughly the same in terms of probability increase each is just under 5.5. To remove hold simply divide each teams implied probability by the total of all implied probabilities. Team Implied Probability / Total Implied Probabilities So to calculate the Ravens true odds youll divide their implied probability (11.76) by the sum (133.03). Ravens: .1176 / 1.3303 = 8.84 Different Events Different Holds Futures markets with fewer teams like an NFL division winner instead of a Super Bowl winner will often have less hold. Generally the more outcomes there are the higher the hold though thats not a steadfast rule. Take this NFC West future from PointsBet. Theyre holding about 15. But for this NFL MVP market with 88 possible betting options theyre holding more than 54. Beware of Artificially-Inflated Futures Markets Sportsbooks will cleverly add more hold to futures by increasing the number of outcomes. Its a concept Ed Miller and Matthew Davidow cover well in their book The Logic of Sports Betting. They use a golf example but I saw an NFL wins market in which the sportsbook used the same concept. Will The Jets or Giants Have More Wins in 2019? Heres one possible way to list this bet with a tie resulting in a push and a refund. Jets -160 (61.53) Giants 130 (43.47) That gives us a total hold of about 5. But the book added in tie as a longshot option. That eliminates the push for anyone who bet on the Jets or Giants. Jets -160 (61.53) Giants 130 (43.47) Tie 1500 (6.25) Now we have a hold of more than 11. While on the surface these bets look similar theyre not because the tie takes away one big option in this market. Thats why its important to convert odds to implied probabilities to see if youre getting a fair shake. via Action Network https://www.actionnetwork.com https://sv88.com
