Started on 14 July 2011 by Chatri Sityodtong and Victor Cui, this Singapore-based promotion runs under Group One Holdings and works nothing like a football competition. There are no clubs, no points, no table and no relegation. The company books its own fight cards and awards its own championship belts.
That structure matters at the betting slip. Sitting under a single menu entry are four separate disciplines: mixed martial arts, muay thai, kickboxing and submission grappling. On a busy night, three of them can appear within a couple of hours of each other. Staking without checking which one you are looking at means betting on a rulebook you have not read, because round length, glove size and even the available finishes shift from bout to bout.
The bookmaker files these cards under Martial Arts, and the upcoming fight schedule shows the format attached to each confirmed bout.
Fights run under the promotion's own Global Martial Arts Rule Set, an adapted version of the unified rules with several deliberate differences. In MMA, knees to the head of a grounded opponent and downward elbows are legal, which sets it apart from most Western promotions. Soccer kicks featured on the earliest events but were removed from the rulebook in 2016.
The second signature is glove size. Muay thai and kickboxing bouts are contested in four-ounce gloves, the same as MMA rather than standard boxing gloves. Thinner padding, higher output, and a naturally larger share of finishes before the final bell.
Combatsport. ONE Championship: discipline | Standard bout format | Rulebook detail | Ways the bout ends |
|---|---|---|---|
MMA | 3 rounds of 5 min, 5 rounds for a title | Grounded knees to the head and downward elbows allowed | KO, TKO, submission, disqualification, decision |
Muay thai | 3 rounds of 3 min, 5 for a title | Four-ounce gloves instead of boxing gloves | KO, TKO, disqualification, decision |
Kickboxing | 3 rounds of 3 min, 5 for a title | Same small gloves, high work rate | KO, TKO, disqualification, decision |
Grappling | One single 10-minute period | Warnings issued for stalling | Submission or referee stoppage |
Read across the table and the totals market stops looking generic: fifteen minutes are available in MMA, nine in the striking codes, and a single ten-minute block in grappling. On scoring, a panel of three judges works from a fixed list of criteria, but the exact wording differs between MMA and the striking disciplines, so treat the scoring method as bout-specific rather than assuming one system covers everything.
Nothing separates this promotion from the wider circuit as sharply as its weight policy, and it came from a tragedy. After a fighter died from the effects of a weight cut in 2015, cutting weight through dehydration was banned outright. A urine hydration test became mandatory, with specific gravity that must not exceed 1.025.
Competitors are entered in the division matching their everyday walking weight, and that weight is checked daily through fight week. Moving between divisions is not a last-minute decision either: the request has to come at least eight weeks before the bout. Divisions are split between men and women, roughly ten in total, from atomweight up to heavyweight.
For anyone reading a pre-match card, this removes two familiar variables. A fighter does not arrive drained by a same-week cut, and the announced division has been stable for weeks.
There is no off-season here. Large numbered events and the ONE Fight Night series run throughout the year, roughly every two to four weeks, and since 2023 — still true in 2026 — a weekly Friday series takes place at the historic Lumpinee Stadium in Bangkok. Few combat sports calendars are that dense.
That density creates a small trap. The same line label can point to a flagship show or to a Friday card, so the event name is the detail worth checking before anything else.
The clock helps if you follow from Djibouti. Bangkok runs four hours ahead and Singapore five, so an Asian fight night lands in your afternoon or early evening rather than the small hours. The occasional United States date flips that arrangement completely. When a card starts inside your active hours, the in-play betting section picks up where the pre-match line stops.
Cards are announced ahead of time, discipline and weight class included. The pre-match line appears once the matchup is official and expands as the night takes shape: outright winners first, derivative markets afterwards, growing in number as fight week approaches.
Early on, the market tree is narrow and reacts to every announcement. A short-notice replacement, an added bout, or a fight upgraded to championship status will move things, and that upgrade alone stretches the contest from three rounds to five, rewriting any duration-based reasoning.
Marquee events usually attract deeper coverage than the tighter weekly shows. If you want to be there when a card opens, set up your account in advance rather than during the announcement rush.
Market choice is discipline-driven. A distance bet on a ten-minute grappling match asks a different question than the same bet on a five-round title fight.
Market | What it settles on | When it earns its place |
|---|---|---|
Fight winner | The plain outcome | Available as soon as the bout is confirmed, the busiest market |
Method of victory | KO/TKO, submission or decision | When contrasting styles meet, striker against grappler |
Goes the distance | Whether the bout reaches the final bell | Sharpest in muay thai and kickboxing, where small gloves count |
Total rounds over/under | The actual length of the fight | Check the format first: 3×5 min or 3×3 min |
Round of the finish | The segment where the fight ends | On cards pairing two known finishers |
Multi-bout accumulator | Several fights from the same event | Best suited to stacked cards, including the Friday series |
Grappling deserves a footnote. The win comes by submission or referee stoppage, and passivity earns formal warnings, so running down the clock is not a strategy the rules reward. Striking bouts pull in the opposite direction: three rounds of three minutes leave a very narrow corridor for a comeback once someone falls behind early.
Start with how the wins arrived rather than how many there are. A record built on submissions reads differently against a pure striker, especially under a rulebook that permits knees to a grounded head.
Next, look at the base discipline. A muay thai specialist on a striking card is in familiar territory; the same athlete in an MMA bout faces threats that never appear in their usual ruleset.
Third, check activity. The Bangkok Friday series lets some competitors fight regularly while others return from long layoffs. Add the format — a five-round championship bout asks a conditioning question that three rounds never raise — plus reach and stance, which carry extra weight in four-ounce gloves. Once the reading is done, sign in to your account and place the selection.
A full event can run for hours and rotate through several disciplines, so being tied to a desktop makes little sense. The 1xBet mobile app carries the card, the current state of each market and your bet history, with alerts when a line opens or closes.
On broadcast, events reach more than a hundred and fifty countries, and in the United States the rights sit with Amazon Prime Video. Coverage is not identical everywhere or for every event, so check the individual bout page instead of assuming a stream will always be there.
Between bouts, the casino games section stays one tap away inside the same app, using the same balance.
The sequence is short. Open an account, fund it, load the event page, then confirm your stake on the chosen bout. Balances are held in Djiboutian franc (Fdj), which keeps conversions out of the way when you bet from Djibouti.
Funding covers the habits people actually use here: D-Money, bank cards, cash and international wallets all appear among the available options, selected method by method inside the cashier.
One piece of timing advice. Get the account and the deposit ready before a major card is announced rather than after. Asian events are published well in advance, and there is little worse than spotting a bout you like an hour before the first bell with nothing available to stake.
Every fight from the Singapore-based promotion's events, across all four disciplines: MMA, muay thai, kickboxing and submission grappling. Each bout is listed on its own with weight class and format, not bundled under one generic heading.
As soon as the card is made official, often weeks ahead. Winner markets come first, and the derivative options are added as the event approaches, with adjustments whenever a matchup or format changes.
The format follows the discipline and the stakes: three five-minute rounds in MMA and five for a title, three-minute rounds in muay thai and kickboxing, and a single ten-minute period in grappling.
Most cards are staged in Asia, and Bangkok sits four hours ahead of Djibouti while Singapore is five ahead. That puts a fight night in the afternoon or early evening locally, with occasional American dates as the exception.
The cashier lists the payment routes commonly used in the country alongside international options, all settled in the local currency, and the whole process runs inside the same app you use to bet.
No. This is a promotion that stages standalone fight nights and awards its own belts, so there are no clubs, no points and no relegation to track across a season.
Availability is shown on each individual bout page. Events are broadcast across a large number of territories, but coverage differs by country and by show, so confirm it rather than counting on it.
