AI in Professional Services Firms: 50 Statistics for 2026

What are the key AI statistics for professional services firms in 2026?

Why do AI adoption statistics contradict each other?

Surveys call three different things adoption. We name them the three levels of adoption.

1. A person uses an assistant, on their own initiative.
2. The firm organizes the use: it pays for tools, writes a policy, sets shared checking standards and measures the return.
3. An agent does a piece of work in production, without a person starting it.

Most headline figures measure level one, as three contradictions show.

Before quoting a figure, ask which level it measures and who answered.

What share of professional services firms use AI?

Individual use runs ahead of what organizations have set up. Few measure the return, and clients expect more than providers deliver.

• 40% of 1,514 legal, tax, accounting, risk and government professionals say their organization already uses generative AI, up from 22% a year earlier. Respondents were screened for familiarity with AI, and consulting firms are outside the sample. Vendor survey. Thomson Reuters Institute, 9 February 2026.

How many consulting firms use AI?

Consultants use AI daily and shared checking standards remain rare. The surveys are small or vendor-run; see AI for consulting firms and our AI governance framework for consulting firms.

• In a field experiment with 758 knowledge workers, run with Boston Consulting Group on realistic consulting tasks, those using AI on tasks within its capabilities completed 12.2% more tasks, 25.1% more quickly. The AI tested was GPT-4. Harvard Business School, September 2023.

Nearly every search firm leader uses a general-purpose tool, and broad adoption is rare. This page keeps four figures, from two vendor-linked sources; see the best AI agencies for executive search and recruiting firms.

• 20% of executive search firms have reached broad AI adoption across multiple workflows, while 78% remain in moderate adoption or early experimentation. 97 firm leaders surveyed with a software vendor, directional. Hunt Scanlon Media, June 2026.

How do accounting and law firms compare?

Both trades report near-universal individual use. The organized layer is thinner, and autonomous delegation is marginal.

• 98% of accounting firms now use AI, most of them daily or several times a day. Vendor survey, nearly 600 accounting professionals. Karbon, 2026.

How were these statistics selected and checked?

All 50 statistics come from primary sources read on 14 November 2026. A figure was kept only when its sentence was found that day in the publisher's page or PDF. Self-reported figures, forecasts and vendor surveys are labeled beside the figure. Thomson Reuters, Wolters Kluwer and LexisNexis also sell tools to the professions they survey.

Left out: figures found only in secondary coverage, vendors' claims about their own product, and studies that mix other sectors with professional services. The McKinsey State of AI, MIT NANDA, LinkedIn Future of Recruiting and Apec figures are absent because their primary pages could not be read that day. Eurostat plans its next update for 15 December 2026. The next full review of this page is set for 14 February 2027. If a figure is wrong, write to us: we correct it and date the correction.
