Data sources: Vault 2027, AmLaw 200 FY2025, and reported Chambers records from the years shown. Chambers record counts can span years and reporting coverage varies; missing years or markets are not compared. Current Chambers bands were checked against each firm’s Chambers profile on Sep 26, 2026; where Chambers splits a table, every Elite firm ranks above every Highly Regarded firm. Missing values shown as “-”.
Firm-only and additional rankings remain available on each firm profile so missing coverage is not mistaken for a head-to-head loss.
