The Billable Hour Is Bifurcating, Not Dying

A widely-cited Sikich analysis this week argues that the billable hour is not collapsing — it is splitting into two distinct economic tracks. The commodity layer (research, first-draft contracts, document review) faces real compression: Clio data shows roughly $27,000 in per-lawyer revenue at risk under hourly billing as AI completes these tasks in minutes. The judgment layer is moving in the opposite direction: M&A partner rates rose 12.4% in 2024, regulatory rates rose 8.3%, and some partners now bill above $2,300/hour. AI-native firm Crosby, which bills per contract rather than per hour, raised a $60 million Series B at a $400 million valuation in March 2026 after 400% revenue growth since October 2025. The strategic question for every firm is whether they have built separate operating models for each layer — or are running a confused middle.
