Kirkland & Ellis Bets $500M on Proprietary AI

Kirkland & Ellis, the world's highest-grossing law firm, announced a $500 million investment to build its own AI platform.

The Chicago-based firm revealed on May 28, 2026, that it plans to spend more than $100 million this year alone, with the remaining investment spread across the next three to four years. The firm will fund this entirely from its revenues, which reached a record $10.6 billion in 2025. The goal is to develop AI tools that Kirkland owns outright, rather than licensing technology available to every other firm in the market.

This move signals a major shift in how the largest law firms think about AI. Rather than buying access to the same tools as competitors, Kirkland is betting that owning proprietary technology will give it a durable edge in winning and handling complex legal work.

Building From the Inside

The platform is being developed by 180 technology professionals, including both Kirkland's internal engineers and data scientists and external technology companies. Those outside partners are contractually restricted from selling the technology to other law firms. Kirkland will own, or retain the right to own, all of the intellectual property produced.
