Odds & prices
Plus and minus odds (+ / −)
In American odds the sign tells you the side and the number is measured against $100. A minus price is the favorite and shows what you must risk to win $100 (−150 = risk $150). A plus price is the underdog and shows the profit on a $100 bet (+150 = win $150).
Neither sign is “better” — they describe the same trade from opposite ends. Minus odds win more often and pay less; plus odds win less often and pay more. What matters is whether the price's implied probability is beatable, not which sign it carries.
Two prices sit at the boundary: +100 and −100 both mean even money, where a $100 bet wins $100.
