How It All Began
The scandal that would shake Turkish football to its foundations started not in the Süper Lig’s glamorous stadiums, but in an obscure second-division fixture. Journalists and betting operator Parimatch noticed something strange about a 2024 match between Ankaraspor and Nazillispor: an unusually high volume of bets had been placed on the game, and not a single shot was taken throughout the match. That anomaly triggered an internal review by the Turkish Football Federation (TFF) that would snowball into one of the most sweeping integrity investigations in European football history.
On September 11, 2025, the TFF handed down the first round of punishments: bans for two club presidents and 18 footballers. It was a preview of what was coming.
The October Bombshell: Referees Under the Microscope
The investigation’s true scale became public on October 27, 2025, when TFF President Ibrahim Haciosmanoglu called a press conference that stunned the football world. The federation had audited all 571 active professional referees in Turkey across every level of the game. The findings were staggering.
371 referees, or 65% of the entire active corps, held registered betting accounts. Of those, 152 had actively placed wagers on football matches, including Süper Lig and international fixtures. One referee had bet more than 18,000 times over a five-year period. Ten others had each placed more than 10,000 bets. Under FIFA and UEFA regulations, even simply holding a betting account is a violation for match officials.
Haciosmanoglu did not mince words. “To get Turkish football back to where it belongs, we need to clean up whatever filth there is,” he told reporters. He called the evidence “a milestone for Turkish football” and pledged sweeping reforms. Former national team manager Senol Gunes added: “If betting and gambling are involved in football, there is no greater corruption than this.”
The First Wave of Bans: Referees
Four days after the press conference, the TFF moved decisively. On November 1, 2025, 149 referees and assistant referees were suspended for periods ranging from eight to twelve months. Because Turkish disciplinary rules state that bans exceeding 45 days trigger licence revocation proceedings, the ruling effectively ended the careers of the vast majority of those punished.
Among the seven elite Süper Lig referees implicated, Yunus Dursun and Egemen Artun each received ten-month bans, while three others were handed eight-month suspensions. Investigations into two additional top-flight officials were kept open. At the same time, 30 match observers from elite and standard categories were also suspended and referred to the Professional Football Discipline Board.
Some of the accused pushed back. One elite referee’s lawyer argued that two fake betting accounts had been opened in his client’s name using stolen identity documents. Another referee insisted he had never placed a bet in his life and that his details had been used fraudulently. Whether those defences succeed remains to be seen in ongoing proceedings.
The Scandal Spreads to Players
By November 2025, the investigation had moved from match officials to the players themselves. The TFF referred more than 1,000 footballers across all divisions to its disciplinary board. On November 13, the federation published a list of 1,024 suspended players.
Of those, 27 played in the Süper Lig, spread across 14 of the 18 top-flight clubs. The names included well-known figures: Eren Elmali, a 25-year-old Galatasaray defender who had played in all four of the club’s Champions League games that season, including a win over Liverpool, and had made 20 appearances for the Turkish national team. He was removed from Turkey’s World Cup qualifying squad when the allegations broke. Galatasaray teammate Metehan Baltaci received a nine-month ban. Besiktas goalkeeper Ersin Destanoglu and long-serving midfielder Necip Uysal were also named. Konyaspor winger Alassane Ndao received a twelve-month suspension.
The players’ reactions were vocal. Elmali wrote on Instagram that a bet had been placed on a former team’s match five years earlier without his knowledge or involvement. Destanoglu called the allegations “completely baseless, unfounded and untrue.” Uysal said a betting account had been fraudulently opened using his national ID number. Whether such claims reflect genuine fraud or standard deflection was left to investigators to determine.
The 997 players from lower divisions brought the total to numbers that had no precedent in Turkish football history. Matches in the third and fourth divisions were postponed for two weeks to absorb the disruption.
The Key Match at the Centre of the Criminal Probe
While the disciplinary process swept through football’s ranks, prosecutors were focused on something more serious: potential match manipulation. The October 26, 2024 Süper Lig fixture between Kasimpasa and Samsunspor became the central focus of the criminal investigation.
During that game, Samsunspor’s Olivier Ntcham missed two penalties within eight minutes. Unusually large bets had been placed on a specific halftime/fulltime outcome that predicted Kasimpasa leading at the break and Samsunspor winning overall. That pattern, investigators concluded, was too precise to be coincidental.
Six suspects were identified as having placed bets tied to that specific match. Fourteen active or former players were found to have wagered against their own teams, which under Turkish law represents one of the most serious integrity breaches possible.
Arrests of High-Profile Figures
In early December 2025, prosecutors ordered the detention of 46 people, and a Turkish court jailed 20 of them pending trial, including active Süper Lig players. On December 26, a further operation across 11 provinces brought in 26 more suspects.
Among the most prominent names detained was Erden Timur, the former vice president of Galatasaray’s sporting operations and one of the most recognisable figures in Turkish club football. Also arrested were Eyupspor vice president Fatih Kulaksiz and Bugra Cem Imamogullari, the TFF’s own Director of External Relations and National Teams Administration. His arrest inside the federation itself deepened the sense that the rot had penetrated the sport’s governing structures.
Prosecutors cited suspicious financial transactions consistent with illegal betting and money laundering, as well as connections between the new detainees and suspects arrested in earlier operations. Financial intelligence from MASAK, Turkey’s anti-money laundering authority, played a central role in tracing alleged gambling proceeds through club-linked bank accounts.
In February 2026, another operation detained 32 more suspects, this time focusing on club executives who had allegedly used illegal betting channels not just for personal gain but, in some cases, to ease their clubs’ mounting debts. Assets linked to lower-division clubs were seized on suspicion of laundering gambling revenue.
Appeals Rejected, Bans Confirmed
On December 29, 2025, the TFF Arbitration Board reviewed appeals from 70 footballers and upheld all of their suspensions, confirming penalties ranging from three to twelve months. The board ruled that betting violations were clearly established and that all procedures had been correctly followed. The bans became final.
The Legal Consequences
Turkish law treats sports betting violations seriously. Under Law No. 6222, individuals responsible for manipulating sporting outcomes face one to three years in prison. Where organised crime is involved, sentences can climb to five to twelve years. The criminal proceedings remained open into 2026, with prosecutors signalling further arrests were likely.
Context and Consequences
The scale of what was uncovered is difficult to overstate. In a country that will co-host the 2032 European Championship with Italy, whose national team reached the Euro 2024 quarterfinals, and whose clubs regularly compete in UEFA competition, the scandal hit at a moment of genuine footballing ambition.
The TFF announced plans for real-time monitoring of referee financial activity, compulsory ethics training, and closer cooperation with law enforcement to track suspicious betting patterns. Turkey’s request for an emergency transfer window, sought partly to allow clubs to replace suspended players, was rejected by FIFA.
The investigation drew immediate comparisons to Turkey’s 2011 match-fixing scandal, which had also swept up major clubs and officials. But in terms of sheer numbers, the 2025 betting scandal surpassed anything that had come before: over 1,000 players, nearly 150 referees, dozens of club officials and executives, and criminal proceedings spanning more than a year. Turkish football’s credibility was left badly damaged, and the work of rebuilding it had only just begun.
