IBIA Reports 300 Suspicious Betting Alerts Across 16 Sports in 2025
The integrity of global sport is rarely tested in stadiums or on television screens; more often, it is tested quietly in betting markets, where abnormal patterns can reveal problems long before scandals become public. In 2025, those patterns triggered 300 formal integrity alerts, according to the latest Sports Betting Integrity Report released by the International Betting Integrity Association (IBIA). Each alert represented a betting anomaly serious enough to be escalated to regulators, sports governing bodies, and law-enforcement agencies.
The alerts related to 16 sports and events held across multiple continents. Football accounted for the largest share, at 37% of all cases, with 110 alerts. Tennis followed with 74 alerts, representing 25%. Table tennis and esports each recorded 34 alerts, accounting for 11% apiece, while basketball generated 27 alerts, or 9% of the total. The remaining alerts were spread across eleven other sports, including cricket, volleyball, beach volleyball, handball, ice hockey, rugby, badminton, snooker, futsal, and floorball.
The geographic spread of cases shows that suspicious betting activity is now firmly global, with notable alert volumes linked to events in North America, South America, Asia, and Africa. Emerging markets are becoming increasingly visible in integrity monitoring as betting participation expands through mobile access and broader regulation. Europe remained the largest source of alerts in 2025, accounting for around 35% of cases, reflecting both the concentration of sporting events and the maturity of its regulated betting markets.
Beyond Europe, alerts were widely distributed, with North America accounting for approximately 16%, South America 15%, Asia 13%, and Africa 10%, while a further 11% were classified as global or unassigned, largely linked to esports events that could not be tied to a specific country. Alerts were associated with events in more than thirty countries worldwide, including Nigeria, Ghana, Tanzania, Brazil, Argentina, Spain, Romania, India, Indonesia, the United States, and Mexico, underlining the increasingly international scope of betting-related integrity risks.
The report places the 300 alerts recorded in 2025 within a multi-year dataset covering the previous three reporting years. IBIA shows year-on-year variation in total alerts across this period, with football and tennis remaining the two most reported sports in each year. The association does not present alert totals as a direct measure of confirmed corruption and does not attribute numerical changes to individual causes.
Khalid Ali, CEO of IBIA, said: “Our 2025 data highlights a familiar integrity risk pattern, with football and tennis continuing to account for most suspicious betting activity. At the same time, the greater scale and reach of our Global Monitoring & Alert Platform means our ability to detect, assess and support investigations across markets and sports has increased. This is driven by operator intelligence generated by our membership and their continued commitment to identifying, disrupting and preventing betting-related corruption through collective action and information-sharing with our partners.

IBIA also presents a quarterly breakdown of alerts, confirming that suspicious betting activity was identified in Q1, Q2, Q3, and Q4 of the year. While the report shows variation between quarters, it does not identify a single quarter as accounting for a majority of alerts. Quarterly figures are used to illustrate distribution across the calendar year rather than concentration in a specific period.
In operational terms, IBIA members monitored more than 1.5 million sporting events globally during the year, covering pre-match and in-play betting markets. Monitoring activity applied to competitions at both professional and semi-professional levels. Alerts were generated through a shared monitoring system operated by regulated betting operators within IBIA’s membership.
The report confirms that all 300 alerts were shared with external authorities. Recipients included sports governing bodies, betting regulators, and law-enforcement agencies, depending on jurisdiction. IBIA states that a number of alerts supported formal investigations and integrity actions, including sanctions, but does not publish the number of sanctions issued. H2 Gambling Capital also forecasts that Africa’s total betting gross gambling revenue (GGR) will grow from US$3.5bn in 2021 to US$19.4bn by 2030.
