What Does +105 Mean in Sports Betting?

+105 is an underdog price. The plus sign means the team is the underdog, and the number is how much you win on a $100 bet. At +105 a winning $100 bet profits $105.00, because the market sees this outcome as less likely.

-105 is the favorite price: you risk $105.00 to win $100, and a $100 bet at -105 returns $195.24 ($95.24 profit), with an implied probability of about 51.2%. +105 is the reverse, an underdog price where $100 wins $105.00. At a sportsbook, the favorite opposite a +105 underdog is usually priced steeper than -105, because the vig comes out of both sides. See the full -105 odds breakdown.
