Yes. If you make a moneyline (ML) bet on a college basketball game and win, you will get your original bet back along with the profit.
For example, if you place a $110 bet with -110 odds and win, you will receive your $110 back along with a $100 profit to equal a total of $210. The only scenario in which you do not get your original bet back is if you lose.
This isn’t only the case with college basketball. If you place a wager in any sport or any bet type whether it be moneyline, point spread, totals, etc., you will receive your original bet back if you win along with the profit you are owed.
Of course, some sportsbooks have different rules than others. If you’re going to place a bet at a sportsbook, be sure to educate yourself on its policies. They always should give you your original bet back if you win, but it doesn’t hurt to double check and make sure you won’t have any issues.
