It’s all good news for US law firms’ for the first half of 2026 – revenues up (12.4%) and a sharp prise in demand – but that’s not the full picture yet as the second half of the year will tell the story about whether US lawyers are having a great year, or just a good one.
The figures, from Wells Fargo’s Legal Specialty Group, cover more than 140 firms, including 69 of the 100 highest-grossing US firms. They show revenue growth accelerating from 11.2% in the corresponding period of 2025.
Demand — measured by lawyer hours worked — rose 4.8%, close to the highest level recorded by Wells Fargo’s legal-sector team. The growth follows an acceleration that began in the second half of 2025 and has continued through 2026.
A meaningful part of that work is connected to the wider AI investment cycle. Law firms are advising on matters including data-centre development and capital-raising, as businesses deploy substantial capital into AI infrastructure and related projects. Reuters reported that Wells Fargo senior consultant and managing director Owen Burman described the market as “very strong.”
But the headline revenue growth comes with a cash-flow qualification.
Firm inventories rose 17.7% in the first six months of the year, while collection cycles slowed by 5%.
In plain English: firms are recording more work and billing more fees, but they are taking longer to convert that work into cash. Whether 2026 becomes merely a good year or an exceptional one may depend on second-half collections.
Lawyer headcount grew 2.9%, below the 3.4% growth reported a year earlier. Productivity rose 1.8%, reversing a 1.4% decline in the first half of 2025, while expenses increased 9.6%.
The Wells Fargo findings broadly align with the Thomson Reuters Institute’s second-quarter Law Firm Financial Index, which recorded a 3% increase in demand and a 7.1% increase in billing rates from the same quarter in 2025.
The message for large firms is straightforward: pricing power and demand remain unusually robust, with AI-related investment adding another source of transactional and advisory work. The harder question is whether firms can collect those higher fees promptly enough to turn revenue growth into maximum profitability.
