The phrase “Top Law Firm” in the United States conjures images of the highest-stakes deals, landmark litigation, and the pinnacle of legal careers. These firms, often referred to as “Big Law,” represent the world’s largest corporations, governments, and financial institutions.
The ranking of these firms is usually determined by two primary metrics: Revenue (size and financial power) and Prestige (reputation and quality of work as ranked by peer lawyers).
