H2 2026 Update: Top Fraud Trends

Research undertaken by TransUnion shows that organisations estimate they're losing an average of 6.5% of annual revenue to fraud, and nearly six in 10 business leaders worry fraud is evolving faster than their ability to stop it. 

Powered by Artificial Intelligence, automation and connected criminal networks, today's fraudsters can build credible identities, imitate trusted communications and target established customer relationships at unprecedented speed and scale.

The H2 2026 Transunion Global Fraud Trends Report  reveals how fraud is moving beyond identity theft and account takeover to exploit trust itself. Combining findings from TransUnion's global intelligence network with business and consumer research conducted across multiple markets, the report aims to provide a view of fraud trends across identity, digital interactions, communications and account activity.
