Boxing betting comes down to three questions: who wins, how they win and how long the fight lasts. Each is settled on the official result at ringside, and the house rules decide the close calls: at FanDuel, an Over 10.5 rounds bet wins only if the fight lasts past 1 minute 30 seconds of round 11.
That rule, and the others on this page, come from FanDuel’s house rules, approved by the Massachusetts Gaming Commission on March 27, 2025. Other books write their own, so read the rules where you bet.

The main boxing bets
The moneyline is a bet on the winner. A fighter at -250 is priced at 71.4%, and an opponent at +200 at 33.3%, so those two prices add up to 104.8% and the extra is the book’s margin. The prices here are illustrations; our moneyline guide shows the working.
A match bet with no draw option is void if the fight is scored a draw. Where a book lists the draw as its own selection, it is a separate bet with its own price.
Method of victory asks how the winner wins: by knockout or technical knockout, or on the scorecards. For betting, FanDuel counts a disqualification and a retirement as a KO or TKO win for the other man.
Round betting names the round in which the fight ends. Group round betting widens that to a range, such as rounds 1 to 3. Both are bets on a stoppage, so if the fight goes to the scorecards, every round bet loses.
How rounds are counted
FanDuel treats 1 minute 30 seconds as half a round, so a round counts as three minutes. In a 12-round fight, Over 10.5 rounds needs the fight to reach 31 minutes 30 seconds of fighting time: 10 full rounds and half of the 11th.
The bell decides which round a stoppage belongs to. A fighter who fails to answer the bell for the next round loses in the round just finished. A fighter who quits after the bell has sounded to start a round loses in that round, even if no punch was thrown in it.
“Will the fight go the distance” is a yes-or-no bet on the fight reaching the final bell. A technical decision counts as not going the distance, and if the scheduled number of rounds changes, the bet is void.
Draws, no contests and changes to the card
A boxing bet can be voided before or after the first bell. A no contest voids every bet not already settled. A fight postponed by more than 48 hours voids the bets, and so does a change of opponent.
A title fight that becomes a non-title fight still has action. If a 12-round fight is cut to 10 rounds, bets on rounds 11 and 12 are void, and the rest stand.
Technical decisions
An accidental foul can end a fight early. If the fight was scheduled for more than four rounds and is stopped after the fourth, it goes to a technical decision for the fighter ahead on the cards, and all bets stand.
Inside the first four rounds, the same stoppage voids the bets, unless a market is already settled or the judges’ cards are used to name an official winner at ringside. An intentional foul that later stops the fight gives the injured fighter a technical decision if he is ahead, and a technical draw if he is behind or level.
Punch stats and knockdowns
Punch stat markets, such as total punches landed or most power punches landed, are settled on CompuBox data. A bet on a round-by-round punch count loses if the fight ends before that round.
For a “to score a knockdown” bet, a knockdown is a fighter being knocked out or given a mandatory eight count. A slip, as ruled by the referee, does not count.
Sanctioning bodies and your bet
The WBC, WBA, IBF and WBO each rank fighters and name their own champions. Their decisions after the fight do not change a bet: FanDuel’s rules say a result overturned on appeal, a suspension or a drug test “will not be recognized for betting purposes.”
If ringside officials never verify a result, FanDuel settles on BoxRec, and only then. For the markets on mixed martial arts, see our UFC betting guide.
Before you bet on boxing
A price on the same fight differs from book to book: -250 is 71.4% and -220 is 68.8%, and that difference is paid on every bet. Compare the books in our sportsbook reviews, and read our handicapper site reviews before you pay for picks.
Paid boxing picks are sold through a handicapping membership. Check a pick’s price against the board before you bet it: a -250 favorite has to win more than 71.4% of the time to be worth betting.
