The call
Kirkland sits atop legal revenue and profit rankings while feeding AI into document work, with Latham nipping at its M&A crown and bar licensing still standing between clients and any AI vendor.
Kirkland & Ellis is one of the world's largest law firms that handles huge business deals, especially for private equity companies. It's hard for competitors or AI to take over because laws require a real lawyer with a license to sign off on nine-figure transactions, and no AI or rival firm can take that legal responsibility away. The big question is whether the firm's earnings per lawyer keep growing as AI does more of the routine work like document review, or whether clients start hiring Kirkland only for final sign-off while doing more work themselves.
Why
01
AI pressure: Harvey, Legora, and OpenAI/Anthropic legal AI tools. AI tools already draft and review documents fast, but a bar-admitted partner still has to sign off and carry liability. Could AI do the core job? Unlikely.
02
Bigger players: Latham & Watkins. Latham beat Kirkland on Bloomberg Law's 2025 M&A tally ($786.7B vs $743.3B), even as Kirkland led Mergermarket's count. Could a giant copy it? No, they are blocked.
03
What protects it. Only a licensed lawyer can put malpractice-bearing sign-off on nine-figure deals, and no AI model carries that liability.

- Could AI replace Kirkland & Ellis lawyers?
