This betting data shows the percentages for handle (money) and bets (tickets) on point spread, total and moneyline wagers. This data is from DraftKings sportsbooks across the U.S. and is updated (usually) twice a day.
How to tell who the public is betting on
If the percentage is high on tickets and money, then you know the public is backing this particular wager.
How to tell when the public and "sharp" bettors have a difference of opinion on a wager
At the risk of generalizing and oversimplifying, a wager with a significantly higher percentage of bets than percentage of handle can indicate that the public is on one side and the professional bettors are on the other.
One example: A point spread wager might have 70 percent of the bets but only 30 percent of the handle. This split would result from a high volume of tickets at smaller increments, presumably from public bettors. Meantime, the sharp money is coming in with fewer tickets (30 percent) but in greater amounts (70 percent of the handle).
