Sumsub: Suspicious transactions more than quadrupled last year

Sumsub has released the third annual edition of its iGaming Fraud Report, and the findings paint a stark picture of rising fraud risk in the sector. The data shows a dramatic 4.5-fold increase in suspicious transaction volumes when comparing the period between Q1 2025 and Q1 2026 to the prior year. This sharp escalation signals that fraudsters are becoming more active, sophisticated, or both, and that iGaming operators face mounting pressure to strengthen their compliance and risk management infrastructure.

The quadrupling of suspicious transactions reflects broader trends in financial crime. As iGaming has grown and matured, it has attracted greater attention from bad actors seeking to exploit weaknesses in identity verification, payment processing, and transaction monitoring. The sheer volume of flagged activity suggests that either fraud attempts are proliferating or that detection systems are catching more incidents—or likely both. Either way, the trend underscores the operational and reputational costs of inadequate fraud prevention.

For operators, the report serves as a wake-up call regarding the importance of robust know-your-customer (KYC) and anti-money-laundering (AML) protocols. Regulators worldwide are tightening expectations around financial crime prevention, and operators that fail to invest in advanced detection and verification tools risk regulatory sanctions, license revocation, or criminal liability. Sumsub's findings validate the business case for third-party compliance solutions that can scale with transaction volume and adapt to evolving fraud tactics.

The implications extend beyond individual operators to the broader ecosystem. High fraud rates can erode player trust, attract regulatory scrutiny, and increase operational costs industry-wide. As the iGaming sector continues to expand into new markets and attract mainstream players, the ability to maintain transaction integrity becomes a competitive differentiator. Operators that demonstrate strong fraud prevention capabilities will likely gain regulatory favor and player confidence, while those that lag risk facing mounting compliance challenges and reputational damage.
