A fight comes down to two people and one result, with nothing to hide behind. A fight can be over in ten seconds or run every one of its scheduled rounds, and the book prices both endings from the moment it opens.
Boxing is punches only, thrown in padded gloves over rounds of three minutes. Mixed martial arts adds kicks, takedowns and submissions, a hold that forces an opponent to give up, over five-minute rounds. Fight winner, method of victory and the round markets are priced on both, before the first bell and while the fight runs.
The cards
Neither sport runs a season or a table. The unit is the card: a night of fights in order, the opening bouts first and the main event, the fight the night was sold on, last. Most weekends of the year have one somewhere.
- UFC. The leading promotion in mixed martial arts. Numbered pay-per-view shows and Fight Night cards both run most weekends of the year, each one built as a bout order from the early preliminaries up to the main event.
- ONE Championship. A Singapore-based promotion that puts mixed martial arts alongside Muay Thai and kickboxing bouts, two other striking codes, on the same card. It runs to a schedule of its own rather than a weekly slot.
- BKFC. Bare-knuckle boxing, fought without the padded gloves of the professional code. Events arrive card by card rather than to a calendar.
- Professional boxing. Everything from a small-hall domestic show to a world-title bill, carried on the sportsbook as one competition. Boxing builds a card around one fight and spends the weeks before it selling that fight.
Four promotions and not a league table between them.
The markets
Fight winner
Fight winner backs one fighter to beat the other. In a two-way market there is no draw to back, so a fight the judges score level voids the bet and the stake comes back. Settlement follows the result announced in the ring, and a later appeal does not reopen it.
Method of victory
One market for how the fight ends rather than who ends it. A knockout is a fighter who does not get up inside the referee's count, and a technical knockout is the referee, the doctor or the corner stepping in before that point. A decision means the three ringside judges scored it, and a disqualification counts as a finish too.
Boxing rounds
Boxing bouts are scheduled over four, six, eight or ten rounds, and twelve for a world title. Total rounds is over or under that number, with the half round set at ninety seconds. Round betting names a round, or a band of them, for the finish. Going the distance asks whether every scheduled round is completed.
MMA rounds
An MMA bout is scheduled for three rounds, five for a championship fight or the main event. The same three markets read off that number, with the half round at two and a half minutes. A fighter who retires between rounds settles them on the last round completed, and a changed schedule voids them.
A big bout has more markets than these four, and one boxing and MMA heading in the Sports Betting Rules settles all of them, sport by sport.
The no contest is in there too: the result given when neither fighter can fairly be handed the win. It voids every bet except the ones already decided.
In-play
The weigh-in is the day before, and it is the last thing that can take a fight apart. Each fighter has to make their weight class, the division limit the bout was agreed at, and the scales are the only word that matters.
A late replacement opponent is a different fight from the one the market priced, and the rules read it that way. If either fighter is replaced, bets on the bout are void and stakes come back. A postponed fight is treated more kindly, and those bets stand for thirty days.
Once the bell goes the price follows the fight. A knockdown, a fighter put down and taking the referee's count, moves it hardest, and a point deducted for a foul moves it too. The fight-winner price is re-cut between rounds. A number read anywhere but the sportsbook belongs to the round it was taken in.
What to look at before you bet
- The style match-up. Boxing asks one question in several different ways. MMA asks several at once, and a bout can be a boxing match for four minutes and a wrestling match for the fifth. Work out which fight each of them wants, and who is more likely to get it.
- Reach and stance. Reach is the span from fingertip to fingertip, and the longer one keeps the other fighter out at the end of it. Stance is orthodox, leading with the left hand, or southpaw, leading with the right. A mismatch changes the angles both have spent years training against.
- Activity and lay-offs. A fighter coming off a recent bout brings their timing with them. A long lay-off, or a jump in class after an easy run, is the gap a card's write-up flags before it flags anything else.
- Cardio over five rounds. Five rounds ask more of the lungs than three, and ten ask more than six. A fighter who fades late is a different proposition from one who was simply outworked early, and the round markets are where that difference gets paid.
- How a round gets scored. With no stoppage, three judges decide it, and judges reward what they can see: clean punching and control in boxing, effective striking and grappling in MMA. Forward pressure tends to read well on a card, damage or not.
The boxing and MMA quick guide
- Check the schedule first. Three rounds or five, six or twelve: that number sets what every other market is worth.
- Read the styles before the records. A record counts wins, not the way they arrived.
- Watch the weigh-in. It is the last point at which the fight can still change shape.
- Fit the market to the view. A winner you are sure of is one bet, a finish you expect is another.
- Give a live fight a round. The opening three or five minutes say more than the build-up managed in a month.
Take a card into the sportsbook, and read the boxing and MMA section of the Sports Betting Rules before a fight finds an ending you had not thought about.
