Firms Risk $143 Billion as AI Execution Lags Behind Ambition
A new report from Thomson Reuters warns that professional services firms in the U.S. face up to $143 billion in client revenue at risk due to ineffective AI implementation. The 2026 Future of Professionals report, based on a global survey of 1,800 professionals in legal, tax, audit, and compliance fields, reveals a widening gap between AI ambition and actual deployment, with significant consequences for revenue and talent retention.
According to the report, 74% of professionals already use AI tools weekly, but 91% believe their organizations are falling short of AI's potential. This disconnect is driving one-third of lawyers, accountants, and compliance professionals to use unsanctioned AI tools, creating invisible risks that organizations cannot monitor or control.
Talent Exodus Looms as AI Expectations Go Unmet
The report highlights that one in four professionals would consider leaving their firm within two years if they do not see expected AI-driven value. This talent risk is compounded by client demands: 78% of clients now consider AI-enabled quality improvements essential, yet only 6% believe most providers deliver on this front. Nearly a third of clients plan to reassess provider relationships within the next 12 months.
“We’re seeing a clear divide emerge,” said Steve Hasker, President and CEO of Thomson Reuters. “Firms that are operationalizing AI are pulling ahead. Those that aren’t are starting to take on real risk, across talent, clients, and financial performance. Closing that execution gap is now a business imperative for professional firms.”
Shadow AI Creates Unmanaged Risk Exposure
A third of professionals are using AI tools not approved by their organizations, with the figure rising to 41% among those who say their organization is moving too slowly on AI. While 96% of professionals say their AI must safeguard confidential data, 94% require verified authoritative content, and 90% need explainable and defensible outputs, 41% lack access to professional-grade tools that meet these standards.
Even where AI strategies exist, execution lags: 35% of professionals say ambitions are not reflected in their daily work, and nearly one in five say their organization still lacks a clear AI strategy. This gap between promise and reality is driving both talent and client attrition.
Three Key Pressure Points for Professional Firms
The report identifies three interconnected areas of pressure: shadow AI creating risk exposure, talent considering departure due to unmet AI expectations, and clients reassessing provider relationships. Firms that fail to operationalize AI effectively face not only financial losses but also reputational damage and competitive disadvantage.
Thomson Reuters' research underscores that AI adoption alone is not sufficient; organizations must translate usage into measurable value to retain talent and satisfy client demands. The $143 billion at risk in the U.S. alone signals an urgent need for professional firms to close the execution gap.
