Kirkland’s Reported $500 Million AI Commitment Raises the Build-or-Buy Stakes

On September 3, 2026, the Financial Times reported that major firms including Kirkland & Ellis, Freshfields and Goodwin are seeking differentiation through bespoke legal AI, with Kirkland reportedly committing $500 million to its own platform. The report said roughly 20% of large firms are personalising or building AI technology, while widely adopted platforms such as Harvey and Legora remain part of the market. The strategic question is shifting from whether to buy a legal assistant to which proprietary data, workflows and evaluation methods can produce defensible client value. Firms without comparable engineering budgets will need disciplined platform configuration and external development partners, but should avoid confusing customisation spend with measurable advantage.
