2026 Data Breach Costs
Coverage from CNBC, Identity Theft Resource Center, and others
The 2026 data-breach cost landscape is defined by IBM and Ponemon Institute research covering hundreds of breached organizations across industries and regions.
Reported findings put the global average breach cost at $4.99 million and the U.S. average at $11.5 million, while healthcare breaches averaged $6.64 million. AI-enabled attacks accounted for a substantial share of malicious incidents and generally carried higher costs, exposing gaps in governance and access controls. Phishing, ransomware, vulnerability exploitation, and third-party compromise remain important routes to exposure, while security automation and defensive AI can reduce response time and losses.
