Kirkland & Ellis Commits $500 Million to Build Proprietary AI Platform as Fried Frank Rolls Out Internally Built FundAssist Tool for Private Equity Funds Practice
Two major US law firms have made significant AI infrastructure investments on the same day, signalling an acceleration in the legal industry's proprietary AI platform race. Kirkland & Ellis has committed $500 million over the next three to four years to develop its own proprietary artificial intelligence platform, in what is described as one of the most ambitious technological bets ever made by a law firm. The firm's strategy is to control its own technology stack to outperform competitors — rather than relying on third-party legal AI tools. Kirkland did not publicly comment on the investment. On the same day, Fried Frank announced the rollout of FundAssist — an internally built AI platform designed to streamline its practice advising private equity funds. The tool uses OpenAI's latest models to process Fried Frank's previous work and identify client-preferred approaches. The firm says it will provide a strategic advantage through client collaboration and cost savings. Together, the announcements mark a qualitative shift in how elite law firms are approaching AI: moving from licensing third-party tools to building proprietary platforms trained on firms' own work product. This in-house development model raises distinct legal considerations — including data governance, client confidentiality obligations over the training data used, and ownership of AI-generated outputs. For students targeting elite US firms in London, the competitive implications are direct: firms that establish early proprietary AI advantages may be able to serve clients faster and at lower cost, reshaping the competitive dynamics of high-end legal practice.
Why this matters
A $500 million proprietary AI commitment from Kirkland — the world's highest-grossing law firm — reframes the AI investment conversation from operational efficiency to strategic competitive differentiation. Firms building on their own work product raise immediate data governance questions: whose client data is used to train the model, how is confidentiality protected, and who owns the IP in the output? Fried Frank's FundAssist is a narrower but directly commercial application — automating PE funds work that currently occupies significant associate and trainee time, which has direct staffing and billing implications. Both moves accelerate the pressure on UK Magic Circle and Silver Circle firms to match the investment pace, or risk a technology gap in the most commercially valuable practice areas.
On the Ground
A trainee on an AI governance matter for a law firm client would draft a data processing agreement markup covering the use of client work product in AI model training, prepare a vendor due diligence questionnaire for an AI platform provider assessing data security and confidentiality protections, and draft a regulatory impact assessment memo on the firm's obligations under UK data protection law when deploying generative AI tools.
Interview prep
Soundbite
Proprietary AI platforms trained on firms' own work product create competitive moats — and confidentiality questions that keep legal teams busy.
Question you might get
“What data protection and confidentiality obligations should a law firm consider before using historical client work product to train an internal AI model, and how would you advise them to mitigate those risks?”
Full answer
Kirkland & Ellis has committed $500 million over three to four years to build a proprietary AI platform, the same day Fried Frank launched FundAssist — its internally built PE funds AI tool powered by OpenAI models. Both moves represent a shift from buying third-party AI licences to building bespoke platforms on firms' own work product, which is strategically significant. For clients, it promises faster, more consistent service; for the legal industry, it creates new questions around confidentiality of training data, ownership of AI outputs, and whether associate-level work is being automated away. The competitive pressure this creates for UK firms — who must match pace without Kirkland's scale — is a defining issue for the legal market in 2026 and beyond.
