$143 Billion at Risk as AI Execution Gap Widens in Professional Services

  • Thomson Reuters' 2026 Future of Professionals report highlights $143 billion in U.S. legal and accounting revenue at risk due to lagging AI implementation.
  • 74% of professionals use AI weekly, but 91% believe their organizations fall short of delivering its full value.
  • One-third of lawyers, accountants, and compliance professionals use unsanctioned AI tools, creating unmanaged risks.
  • 24% of professionals may leave within two years if AI expectations aren't met, while 32% of clients plan to reassess provider relationships within a year.

Thomson Reuters' report underscores a growing divide between firms that have operationalized AI and those lagging behind, with material consequences for revenue, talent retention, and client relationships. The findings highlight the urgency for professional services firms to close the execution gap as clients increasingly demand AI-driven value and employees prioritize access to professional-grade AI tools.
