Context and IBIA’s Role
The IBIA is a global watchdog organization whose members include many of the world’s largest regulated sports betting operators. The association represents over 80 companies and 140 betting brands that account for an estimated $300 billion in annual global betting turnover, or approximately 50% of the regulated commercial online betting market.
The association’s primary goal is to protect the integrity of the sports betting market by identifying and reporting potentially fraudulent activity. It achieves this through a sophisticated global monitoring and alert system that analyzes betting patterns from its members to detect irregularities that may indicate match-fixing or other corruption. The Q2 2025 report is a product of this ongoing monitoring effort.
