Thomson Reuters 2026 Report: AI Adoption Hits Critical Mass in Professional Services
Thomson Reuters’ 2026 AI in Professional Services report surveyed 1,514 professionals across legal, tax, accounting, and risk in 27 countries. Organizational AI adoption nearly doubled from 22% to 40% in one year, 82% of users engage weekly, and 15% already deploy agentic AI. But only 18% measure ROI, and the strategy gap is widening. This is what the numbers actually mean for professional services firms.
