EY uses AI in audit and appears likely to become Anthropic's auditor
Accounting Today reports that EY posted a record-low 5% result in the PCAOB's 2025 inspection report while using AI in its audits. Separate reports say EY may become Anthropic's auditor, while the other Big Four firms deepen their own AI ties.
Who is affected and how
- accountant
- The use and documentation of AI tools in audit should be set up with PCAOB inspections in mind.
- chief financial officer
- The overlap between auditor relationships and AI providers calls for an independent assessment.
