Kirkland & Ellis, the world’s highest-grossing law firm, has set aside $500 million to develop its own artificial intelligence platform, signaling one of the largest AI investments made by a law firm to date, according to Financial Times. The initiative is designed to create proprietary technology that captures and deploys the firm’s institutional knowledge rather than relying solely on third-party AI tools available across the legal industry.
According to Kirkland & Ellis Chairman Jon Ballis, the firm expects to spend more than $100 million in 2026 and hundreds of millions more over the next three to four years developing customized AI services. These expenditures are in addition to the firm’s ongoing investments in licenses for external AI platforms.
The project aims to transform the firm’s collective expertise into a technology platform that can be used throughout the organization. Ballis said the initiative reflects the firm’s belief that widely available AI tools are becoming table stakes across the legal profession, requiring leading firms to develop differentiated capabilities to maintain competitive advantages.
The investment comes as law firms worldwide accelerate AI adoption. The legal sector has increasingly embraced platforms from companies such as Harvey and Legora, while several firms have pursued proprietary tools and strategic partnerships with AI developers. Earlier this year, Freshfields announced a collaboration with Anthropic that gives the law firm access to emerging AI technologies while helping develop legal-specific tools.
Kirkland’s platform is being developed by a team of approximately 180 technology professionals, including engineers and data scientists working alongside external partners. The firm will retain ownership rights to the resulting technology and intends to prevent outside developers from commercializing the platform for other organizations.
The system is being designed using knowledge gathered from roughly 250 Kirkland lawyers, including 100 partners, with the goal of embedding their workflows, expertise, and decision-making processes into the platform. Rather than relying on separate AI applications for individual tasks, the firm envisions a unified platform that can support entire legal matters from start to finish.
Kirkland plans to fund the initiative from its own revenues, reducing the profits available for distribution to equity partners in the near term. The firm generated a record $10.6 billion in revenue last year, providing the financial resources needed to support the investment.
The initiative also reflects broader changes taking place across the legal industry. As AI automates many routine legal tasks, firms are increasingly exploring alternative billing structures that focus on outcomes rather than billable hours. Ballis said Kirkland already handles a number of matters using value-based pricing models and expects that trend to accelerate as AI becomes more deeply integrated into legal work.
The name of Kirkland’s AI platform and the technology partners involved are expected to be announced in the coming weeks.
