The ICC Anti-Corruption Unit: Cricket's Fight Against Match Manipulation
The ICC Anti-Corruption Unit (ACU) was created in 2000 following the Cronje scandal and monitors all major cricket tournaments worldwide for corruption, conducting investigations and educating players about the risks of approaches from bookmakers.
The ICC Anti-Corruption Unit (ACU) was established in 2000 as cricket's response to the match-fixing revelations of that year — particularly Hansie Cronje's confession and the wider investigations that followed in India and elsewhere. The ACU operates at all major ICC events and works with national cricket boards to monitor suspicious activity, investigate allegations, and educate players about the risks posed by bookmakers and corrupt agents. It also works with law enforcement agencies in multiple countries and coordinates international investigations.
How the ACU Operates
The ACU deploys investigators at all ICC events — World Cups, Champions Trophies, Test series and bilateral tournaments. Players are required by the ICC Code of Conduct to report any approach from a bookmaker or corrupt agent immediately. Failure to report an approach is itself a breach of the code — regardless of whether the player engages with the approach. ACU investigators also monitor betting markets for unusual patterns that might suggest prearranged outcomes (spot-fixing) rather than match outcomes. Evidence of unusual wagering can trigger investigations.
Major Investigations
Since its creation, the ACU has investigated corruption in multiple countries and tournaments. Spot-fixing in the Pakistan Super League, the Indian Premier League, the Bangladesh Premier League and the Caribbean Premier League have all been investigated. Players from Pakistan, Bangladesh, Afghanistan and other nations have received bans. The scale of illegal cricket betting — estimated at hundreds of billions of dollars annually, primarily through Asian markets — means corruption risk remains a permanent feature of professional cricket.
Frequently asked questions
When was the ICC Anti-Corruption Unit created?
The ICC ACU was created in 2000, directly in response to the Hansie Cronje match-fixing scandal and the broader investigations of that year. It is now permanently deployed at all major ICC events.
What must players do if approached by a bookmaker?
Players must immediately report any approach from a bookmaker or corrupt agent to the ACU. Failure to report an approach is itself a breach of the ICC Anti-Corruption Code, regardless of whether the player engaged with the approach.
How does the ACU detect spot-fixing?
The ACU monitors betting markets for unusual patterns — spikes in wagering on specific outcomes like no-balls or wides that might indicate prearranged events. It also receives intelligence from law enforcement and deploys investigators at tournaments. Unusual market movements can trigger formal investigations.
