Favorites always carry minus odds because they represent reduced risk and require bigger wagers for lower payouts. Underdogs show plus odds, providing higher potential profits to account for the increased risk. This clear distinction helps punters quickly assess the theoretical likelihood and possible value of each betting opportunity.
