Match-fixing

What counts as manipulation

The Council of Europe's Macolin Convention gives the definition most codes now track: manipulation of sports competitions is an intentional arrangement, act or omission aimed at an improper alteration of the result or the course of a competition, in order to remove all or part of its unpredictable nature with a view to obtaining an undue advantage. Two things follow from that wording. The offence does not require a bet — a result altered for a league place, a favourable draw or a transfer fee is manipulation on the same terms. And it does not require an effect: an arrangement is enough.^[1]

Manipulation is one of a family of offences that are constantly confused with one another. Betting by a participant is a separate and lesser offence, and by a wide margin the commonest charge in world sport; it is covered on betting and sport. Misuse of inside information is a third offence, and often the one actually charged where no bet can be traced to the participant. Bribery of officials for votes, hosting rights or broadcast contracts is a governance offence, dealt with on corruption in sports governance; the overlap case is the match official bribed to alter a match, which is manipulation. And manipulation has nothing to do with anti-doping, which runs under an entirely separate code with its own tribunals — as in tennis, where one agency administers two programmes with different burdens and different sanction ranges.^[2]

The Olympic Movement Code on the Prevention of the Manipulation of Competitions was approved by the IOC Executive Board in December 2015 and first applied at Rio 2016; the edition in force was adopted in September 2022, with model rules for international federations and national Olympic committees reissued in May 2024. Adoption is not optional: the Olympic Charter requires the federations within the Olympic Movement to adopt and implement it as a condition of recognition, and compliance is mandatory across the Movement during the Games. It is drafted to comply with Macolin, and breaches at the Games are handled under the IOC's own ethics procedure.^[3]

The treaty layer, and how thin it is

The Macolin Convention opened for signature at Magglingen/Macolin on 18 September 2014 and entered into force on 1 September 2019. As of 3 September 2026 it had 17 ratifications and 26 further signatures not followed by ratification. The Parties are Armenia, Belgium, Estonia, France, Greece, Iceland, Italy, Lithuania, Norway, Portugal, Moldova, San Marino, Serbia, Spain, Sweden, Switzerland and Ukraine; Armenia and Estonia were the only additions in 2026. Germany, the Netherlands, Poland, Türkiye, Romania and the United Kingdom have signed and not ratified. Australia and Morocco have signed as non-member states. The European Union has neither signed nor ratified.^[4]

The Convention's operative idea is the national platform: a standing hub in each state that collects and distributes information and coordinates between public authorities, the sports movement and betting operators, so that intelligence held by one of the three reaches the other two. The platforms are networked through the Group of Copenhagen, which advises the Convention's Follow-up Committee and now has more than 45 members spanning every continent — substantially more than the number of Parties. The instrument has therefore diffused faster as operational practice than as binding law, which is the honest summary of the treaty layer: a small legal core inside a much larger working network.^[5]

Detection: what an alert is, and what it is not

Three monitoring systems produce three incommensurable numbers, and comparing them is the commonest error in coverage. Operator-side, the International Betting Integrity Association draws alerts from its members' own customer accounts: 90-odd companies operating more than 200 brands, monitoring over 1.5 million events a year across more than 80 sports. It reported 300 suspicious betting alerts in 2025 across 16 sports — football 110, tennis 74, esports 34, table tennis 34, basketball 27 — with Europe 35 per cent of the total, North America 16, South America 15, Asia 13 and Africa 10.^[6] Data-company side, Sportradar monitored more than a million events across 70 sports and identified 1,116 suspicious matches, one per cent fewer than in 2024, with football 618, basketball 233 and tennis 78; more than 99.5 per cent of monitored events were free of suspicion.^[7] Lottery-side, the state lotteries run their own mutualised system, United Lotteries for Integrity in Sports, renamed from the Global Lottery Monitoring System by member vote in October 2022.^[8]

These count different things over different universes. They cannot be added, and neither corrects the other. Two further cautions belong with any figure: IBIA revises its own back series as investigations close — 2024 was published at the time as 219 and is now printed as 232 — so year-on-year comparisons drawn from different reports compare two vintages of the same statistic; and a fall in detected suspicious matches is a change in a detection statistic, not a measurement of how much manipulation occurred.^[6] [7]

What an alert means is best put by the body that publishes the fullest annual account of it. The International Tennis Integrity Agency records every alert as an indicator that something inappropriate may have happened, and states plainly that "an alert on its own is not evidence of match-fixing": unusual betting patterns can follow from incorrect odds-setting, well-informed betting, fitness, fatigue, form, conditions or personal circumstances. Its 2025 review goes further, and the finding deserves to be better known — in 2025 more cases were proven on behaviour that did not trigger a match alert than on behaviour that did. In the sport with the most mature integrity unit in the world, betting monitoring was the minority route to a proven case.^[2]

Why alerts cluster at the bottom of every pyramid

The distribution is stark and it is stable. Of the 68 match alerts the tennis integrity agency itself recorded in 2025 — a different count from the 74 reported operator-side, on a different universe of events — sixteen came from ITF M15 events, twelve from M25 and twelve from ATP Challenger 75, while there was none at ATP 250 level or above apart from a single Grand Slam alert. Nearly six in ten of the year's alerts sat in three tiers where a first-round loser may not cover the week's expenses.^[2] [6]

Four mechanisms explain the shape. Pay: the January 2026 United States college-basketball indictment alleges that fixers deliberately targeted players for whom bribes of ten to thirty thousand dollars would meaningfully supplement or exceed their legitimate earnings — a calculation that only works low down.^[9] In-play markets: live betting makes up the great majority of tennis markets and almost all of them at ITF level, and live markets need live data. The data chain: at events with no broadcast, the score is captured by a person at the venue and transmitted with a latency advantage; where that person is corruptible, the manipulation and the data supply are the same hand. The 2018 independent review of integrity in tennis identified precisely this — the difficulty of protecting matches with no spectators — and the response was both institutional and commercial: the Tennis Integrity Unit was replaced by an independent agency, the ITF committed an eight-million-dollar integrity investment in accreditation and access control, and the supply of official live scoring data from the lowest-tier events was phased out from December 2018 on a progressive, conditional basis.^[10] [11] Volume: there are far more matches at the base of any pyramid than at the top, so a raw alert count skews downwards even if the rate per match were flat — a point the ITIA makes about its own figures.^[2]

The same logic explains where markets exist without any governance at all. Every one of the 34 table-tennis alerts IBIA reported in 2025 concerned events outside the international federation's competitions, and much of the sport's betting market is built on unsanctioned exhibition circuits over which no federation has jurisdiction. Markets form where liquidity is, not where rulebooks are.^[6]

Investigation: contractual powers against police powers

A federation's investigative powers come from contract, not from law: entering a competition is acceptance of its code, and refusing to cooperate is itself an offence. That produces powers a police force does not have without judicial authorisation. Under the 2026 tennis programme, where there are reasonable grounds to believe an offence may have been committed, the agency may demand production of phones, tablets and laptops for copying, access to social-media and cloud accounts, itemised phone billing, message content, bank statements, cryptocurrency wallets and money-transfer histories, together with a written account of the facts, with compliance required immediately where practical. There is a standing duty to preserve evidence, a rule that a person is treated as uncooperative if their own counsel obstructs, and an express power to draw an adverse inference from non-compliance. The trade is procedural: interviews are recorded, a representative may attend, and transcripts are provided on request.^[12]

What police have and federations do not is equally decisive: search and seizure, arrest, interception, the power to compel testimony from people who are not in the sport at all — bookmakers, financiers, relatives — and the mutual legal assistance needed to reach a fixer in another country. Neither toolkit is sufficient alone, which is the argument for the national platform: the manipulation is inside the sport, the money is outside it, and no single body can see both. Reporting routes reflect the same split — the cricket anti-corruption unit publishes a confidential line inside its own code, and the tennis agency added a confidential messaging service for players, coaches, officials and agents in 2025.^[13] [2]

Proof, and the offences nobody expects

There is no single standard of proof in sport, and writing as if there were is a common mistake. Cricket's code requires the tribunal to be "comfortably satisfied", expressly "greater than a mere balance of probability but less than proof beyond a reasonable doubt", with the burden on the governing body.^[13] Tennis applies the lower civil standard: the agency must establish the offence "by a preponderance of the evidence".^[12] Evidence rules are relaxed in both — tribunals are not bound by judicial rules of admissibility, circumstantial evidence suffices, direct evidence is not required, and a court judgment may be accepted as proof of the facts it found. A provisional suspension runs on a lower test again and is not a finding of anything: in tennis it stands unless it is unsupported by "substantial evidence", meaning more than a mere scintilla.^[12] [13]

Two features of these codes surprise people who meet them for the first time. The first is that the offer is the offence: it is enough that an approach was made, whether or not money changed hands and whether or not any match was affected, and poor performance is evidence that may support an allegation but its absence is no defence.^[12] The second is that failing to report an approach is itself a disciplinary offence, and a serious one. Tennis players must report as soon as possible even where no money was offered or discussed, must report what they know or suspect about others, and may be sanctioned as if they had committed the offence themselves; non-reporting and non-cooperation carry the same maximum — permanent ineligibility — as fixing. The FIFA code sets a minimum two-year ban and a fine of at least USD 15,000 for failing to report an approach, and cricket's code separately criminalises non-disclosure of approaches and of gifts above a threshold, failure to cooperate, and obstruction of an investigation. The only defence recognised in the tennis code is duress, and it is narrow: prompt reporting plus an honest and reasonable belief in a significant threat to life or safety.^{[12] [13] [14]}

Sanctions, and why a sporting ban travels further than a conviction

The tariffs are set out in the codes. Football: a minimum five-year ban on any football-related activity and a fine of at least USD 100,000, a lifetime ban in serious cases, and — unusually — measures for match manipulation that cannot be suspended.^[14] Cricket: five years to life for the corruption offences, one to five years for betting offences, six months to five years for the general and non-disclosure offences, with fines discretionary on top; the tribunal expressly has no power to alter the result of any match.^[13] Tennis: a fine of up to USD 250,000 plus disgorgement of winnings, three years' ineligibility for the general run of offences and up to permanent ineligibility for the gravest, with no ranking points accruing during a suspension.^[12]

The reach of those bans is a mechanism, not an assumption, and football's is the clearest. Under Article 70 of the FIFA Disciplinary Code, a member association or confederation that sanctions someone for a serious infringement including match manipulation shall request that the sanction be extended worldwide; the request must enclose the decision and proof that the person was cited, heard, notified and told the decision would be submitted for extension. If the body does not ask, FIFA may extend the decision on its own motion. The chairperson deciding the extension "may not review the substance of the decision", and once extended the sanction has the same effect in every association and confederation as if each had imposed it. A private, administrative, non-merits step therefore makes a national ban globally enforceable — while a criminal conviction stops at the border, and reaching a fixer abroad requires extradition, a process that in the best-known cricket case took twenty years.^[14] [15]

The geography of enforcement is wider than the headlines suggest. Tennis alone sanctioned 48 people in 2025 — France, the Dominican Republic, China, Thailand, Uzbekistan, Italy, Argentina, Rwanda, Morocco, Tunisia, Bulgaria and a dozen more — with four lifetime bans and fixed terms up to twenty years; the agency links the longest of those bans to organised criminal networks and third-party organisers rather than to isolated player misconduct. Sportradar recorded support for 125 sanctions across seven sports and all six major continents in the same year.^[2] [7]

Criminal law, and how differently the two tracks end

Some states have a purpose-built offence. Italy's Law 401 of 1989 criminalises offering money or advantage to a participant to achieve a result other than that of fair competition, and the intention suffices whether or not the manipulation occurs. Spain's penal code carries a sports-corruption article reaching directors, athletes and referees. Germany inserted two provisions into its criminal code with effect from 19 April 2017 — one for manipulation connected to public betting, one for manipulation of professional competitions with no betting nexus at all — though German academic commentary has been sharply critical of the drafting. Poland's offences sit in its sports statute rather than its criminal code, and Australia's are state offences, Victoria's dating from 2013 and implementing a national policy agreed by all federal and state sports ministers in 2011. Others prosecute through general law: the 2010 Pakistan spot-fixing case was tried in London as conspiracy to accept corrupt payments and to cheat,^[25] India charged the Cronje-era bookmaker with cheating and conspiracy,^[15] and China convicted its former national football coach of giving and accepting bribes rather than of any sports-specific offence.^[22] Offences sit variously in criminal codes, sports laws and special statutes, and differ in scope, elements and penalty — the fragmentation Macolin was written to reduce.^[16] [17]

Because the tracks are independent, they end differently on identical facts, and Türkiye supplies a complete one. Sixty-one people were arrested in the 2011 investigation, and the Fenerbahçe chairman was convicted in July 2012 and sentenced to more than six years. An Istanbul court acquitted him of all charges in October 2015 for lack of evidence;^[31] the Court of Cassation reversed the acquittal in January 2020;^[32] and a retrial acquitted all defendants again in November 2020. Meanwhile the sporting sanction — the club's two-season exclusion from European competition — was never undone. Reporting the conviction without the acquittals, or the acquittals as though they vacated the ban, both misstate the record.^[18] Elsewhere prosecutions have simply not concluded: the alleged organiser of the Singapore network was detained without trial, released when the Court of Appeal held the detention unlawful, and re-detained under a fresh order in December 2015 — nothing about his position since is on the public record, and he has never been tried for match-fixing; and the 2025 Hungarian prison sentence imposed on the best-known Asian fixer was for human trafficking rather than manipulation, and is under appeal.^[19]

Where the cases have actually been

Italy is routinely told as one story and is three. Calciopoli (2006) was not a betting case at all: club executives were found to have influenced the assignment of referees, and Juventus was relegated and stripped of two titles. Scommessopoli (2011) was a betting-driven fixing ring, sixteen arrests including a former international, and it produced the textbook non-reporting case — Antonio Conte was banned for ten months, reduced to four on arbitration, for failing to disclose knowledge of two fixed matches, and was never accused of fixing anything. The inquiries from 2023 onward are neither: they concern illegal betting on unlicensed platforms, not manipulation, and the players sanctioned were sanctioned for betting.^[20]

Europol's Operation VETO, announced in February 2013, is the investigation whose figures are most often misstated. It flagged 680 suspicious — not proven — matches, some 380 in Europe and 300 elsewhere, with 425 players, officials and criminals from more than fifteen countries suspected, over €8m in betting profits and €2m in corrupt payments identified. Investigators involved criticised the presentation at the time for not distinguishing the European cases, many already known and prosecuted, from the newer material outside Europe.^[21]

China has run the largest enforcement documented in this period, measured by the number of people banned. In September 2024 the football association banned 43 people for life and seventeen more for five years after a two-year investigation identified 120 fixed matches involving 41 clubs;^[33] the former national coach was sentenced in December 2024 to twenty years for bribery and lost his appeal in 2025;^[22] and in January 2026 the association issued 73 further lifetime bans and docked points from eleven of the sixteen top-division clubs; nine began the March 2026 season on negative points.^[23] South Korea produced the first documented video-game fixing case in 2010, with ten professional players banned for life, and further criminal sentences in 2015–16 — esports has been part of this subject for longer than most accounts allow, and at 11 per cent of the 2025 operator-side total it now ties table tennis as the third-largest alert category.^[24] [6]

Cricket shows the two tracks running side by side. The 2010 spot-fixing case ended with an ICC tribunal imposing bans of five to ten years and, separately, a London court imposing prison sentences of six months to two years and eight months on the same facts. Its centre of gravity has since moved to associate and franchise competitions, where recent bans of five to eight years have been imposed on players from Oman, the United Arab Emirates and the United States.^[25] [13] In snooker, ten Chinese players were sanctioned in June 2023 — two lifetime bans and eight fixed terms reduced for early admission, not ten life bans as often reported.^[26] In Brazil, the Penalidade Máxima investigation opened in February 2023 produced sporting punishments for 22 athletes, including five permanent bans, with no criminal penalty applied to any athlete on the published record.^[27] And in Africa, where alerts have risen sharply since 2023 — 31 in 2025 against 15 two years earlier — the documented modality is the official rather than the player: FIFA banned a Ghanaian referee for life in 2017 for unlawfully influencing a World Cup qualifier, and the match was ordered replayed — one of very few instances anywhere of a result being undone for manipulation.^[6] [28]

2026: the alert and the evidence, side by side

The year's clearest lesson came from the World Cup. The Group of Copenhagen mobilised fourteen national platforms to monitor all 104 matches, placed fifteen under enhanced monitoring — particularly in the final round of group games — issued seven Yellow Notices, and for the first time continuously monitored prediction markets, which it noted present new difficulties because users can wager anonymously through payment methods that are hard to trace. FIFA's own task force reported no evidence of suspicious betting or manipulation at the tournament.^[34] Both statements can be true at once: a notice flags activity warranting scrutiny, and no match met the threshold for a finding. Read as a contradiction it produced headlines; read correctly it is the whole subject in miniature.^[29]

Otherwise the direction of travel on the operator side was upward — alerts rose about a tenth year on year in both the first and second quarters of 2026, with esports at a fifth of the second-quarter total — while the treaty layer moved by two ratifications. The regulatory gap that closed no further is the one the monitors themselves named: prediction markets sit largely outside the licensed-sportsbook perimeter that the alert systems cover.^[30] [4]
