Three Wall Street banks are demanding lower fees from elite law firms because AI speeds up legal work.
Citigroup wants firms to disclose AI savings, and Morgan Stanley will use competitive bids by year-end.
The move challenges the traditional billable-hour model.
What happened
Goldman Sachs, Morgan Stanley and Citigroup are pressing elite law firms to lower fees, arguing AI is sharply reducing the cost of routine legal work such as research, document review and contract analysis. Citigroup has begun asking firms bidding for its business to disclose how much they are saving by using AI, and Morgan Stanley plans to put most of its outside legal work up for competitive bids by the end of the year.
Why it matters
The billable-hour model has long made partners at top firms extraordinarily wealthy — top lawyers have "for a long time been compensated on the foundation of [associates billing for long hours]", as Morgan Stanley's general counsel Eric Grossman put it. The banks' push could amount to "a fundamental altering of the revenue foundation for these mega firms", Grossman added.
What to watch
Nearly half of large law firms surveyed this year by Citi's law firms group said AI had already affected how they price their work. Big Law's hourly charges have surged since 2023, with associate rates climbing 33% to an average $798 this year, according to Persuit data.

The banks' demand marks a direct challenge to the economic engine of Big Law, where profits have traditionally been built on armies of junior associates billing by the hour. Citigroup's global head of legal, Adam Meshel, stated the expectation plainly: if AI cuts hours, costs should come down "significantly per transaction". Morgan Stanley's general counsel Eric Grossman called the compensation model "extraordinarily unstable", suggesting the pressure could reshape how top firms generate revenue.
The push comes after a period of soaring legal bills — associate rates at the largest firms have climbed 33% to an average $798 this year, with partner rates up 29% over the same period, according to Persuit data. While nearly half of large law firms surveyed by Citi's law firms group say AI has already affected their pricing, the disruption has so far been limited. Shama Hyder, a professor of practice at the Link School of Business, argues the banks' demands are feasible because firms can compare similar matters based on total hours, staffing, and cost, even if they cannot measure every minute AI saves. The outcome, she suggests, is a battle over who captures the time and money the technology saves — "Using AI to produce the same invoice faster is not going to satisfy clients."
