ITIA Quarterly Update - Q4 2025

Detailed in this update are our final quarterly figures for 2025.

Q4 2025, in terms of sanctions, was led by the significant sanctions of French tennis player Quentin Folliot and Chinese tennis player Renlong Pang, who received 20-year and 12-year periods of ineligibility, respectively, for their roles in corrupting tennis.

In the coming weeks, our regular and detailed annual review will be published for last year – providing in-depth information about the ITIA’s governance, financial reporting, strategic progress, and selected case studies – alongside our reflections on the past 12 months.

In the meantime, we continue to encourage the tennis community – including players, officials, media, or support team members – to get in touch with any queries they may have about tennis’ anti-doping or anti-corruption programmes.

ITIA colleagues are available to meet with in person during the tennis season, including at the Australian Open in the coming weeks, or remotely, and players and their support teams can contact the ITIA at any time by using The Line.

Below, you will find an update on sanctions and suspensions issued during Q4 of 2025, as well as key reporting data, including testing figures from our anti-doping programme and match alerts.

Match alerts

In the fourth quarter of 2025, the ITIA received a total of 23 match alerts through its confidential Memoranda of Understanding with the regulated betting industry.

A note about match alerts:

Every alert reported to the ITIA is recorded, assessed and followed up as an indicator that something inappropriate may have happened. It is important to note that an alert on its own is not evidence of match fixing.

Unusual betting patterns can occur for many reasons other than match fixing – for example incorrect odds-setting; well-informed betting; player fitness, fatigue or form; playing conditions and personal circumstances.

The number and distribution of alerts are reported quarterly. Care should be taken in drawing any conclusions about prevailing corruption across the tennis ‘pyramid’ as there are many more matches at the bottom than at the top. More complete analysis will be published in our annual report.

Where analysis of a match alert does suggest corrupt activity, the ITIA conducts a full, confidential investigation.

In addition, the ITIA considers intelligence from various sources, and encourages anyone with any concerns to contact the ITIA.

Tennis Anti-Doping Testing Programme – Q4 2025 testing figures

These figures outline the number of samples taken from players, not the number of tests (multiple samples e.g., urine and blood, can be taken from players when they are tested). All tests undertaken this quarter were with no notice.

The ITIA is responsible for the TADP across all members' tennis events. Tests in Q4 of 2025 took place at events ranging from ITF $15K level to the Billie Jean King Cup, Davis Cup, WTA and ATP Finals, with in and/or out-of-competition testing undertaken in 56 different countries

ABP = Athlete Biological Passport
