For example, if the odds for a particular team to win a championship are +500, this means that a bettor would receive a payout of $500 for every $100 they wagered if that team goes on to win the championship.
What does +900 mean in betting: If you wager on a team at +900 you would win $900 for every $100 you bet. This is considered a sizable underdog in the sports betting world at 9/1.
