Law firms just posted their best pricing year in two decades. Their clients noticed — and started paying less.
That contradiction is the defining feature of corporate legal spend in 2026. The Thomson Reuters Institute's Law Firm Financial Index recorded worked rates climbing 7.3% in the first quarter of 2025, the fastest pace in nearly 20 years, and the first half closed at 7.4%. Profit per lawyer rose 8.4% above pre-2022 levels. And yet the largest corporate clients — the ones with real leverage — saw their actual spend per hour fall. Companies with more than $10 billion in annual revenue paid partners 12.2% less per hour in Q2 2025 than a year earlier. They didn't negotiate harder. They moved the work.
"Every 1% rate increase has translated into more than 0.9 percentage points of profit growth," the TRI analysts wrote of the 2025 market — "a powerful formula." It is also a formula clients can read.
The Rate Paradox: Firms Raise Prices, Big Clients Pay Less
This is the central tension in every 2026 legal budget meeting. Standard rates at major firms keep climbing — $2,000-an-hour associates are no longer theoretical at the top of the market — while effective rates diverge by client size. Midsize companies paid roughly 2% more per partner hour. The Fortune-scale buyers paid materially less, not by haggling over the same invoices, but by reallocating work down the cost curve: to regional firms, to boutiques, to alternative legal service providers, to their own legal departments.
The 2025 State of the Corporate Law Department Report from Thomson Reuters confirmed the posture behind the move. Cost control was the top strategic priority for general counsel in the US, the UK, and Canada. In the UK, 28% of corporate legal departments planned for spend to decline in 2025, up six points from the year before — while matter volumes kept rising.
GCs are spending less per hour while doing more work. The math only balances because they stopped buying every hour at the top rate.
The Insource Economy
The single biggest structural shift in corporate legal spend benchmarks is the migration of work inside. An Association of Corporate Counsel and Everlaw survey found 66% of legal departments bringing more work in-house to control costs, up from 59% the year before. It was the leading cost strategy by a wide margin — ahead of alternative fee arrangements, ahead of panel consolidation.
The staffing numbers back it up. The ACC's 2025 Law Department Management Benchmarking Report found median total legal staff at midsize companies rising from 16 to 20, with internal legal spending jumping to $3.1 million from $2.8 million. Companies aren't just shifting work — they're building departments to hold it. And the outside counsel panel is shrinking to match: a median of 10 law firms this year, down from 14 last year.
Small and midsize companies are actually leading the insourcing trend — 69% and 67% respectively, versus 58% of large companies. But the large companies have a second lever the smaller ones don't: procurement power over their panels. They are consolidating spend into fewer firms, demanding data through e-billing platforms, and benchmarking every phase of every matter. The GC who once managed relationships now manages a supply chain.
Technology Spend: The AI Discount Nobody Has Cashed
Legal technology spend is the line item everyone is increasing and nobody can quite measure. Half of legal departments — 52% — had implemented AI tools in 2025, up from 34% the year before, according to the ACC benchmarking data. Corporate legal is, remarkably, ahead of many law firms in generative AI adoption, per Thomson Reuters Institute data.
But the savings haven't materialized. A 2025 ACC and Everlaw survey found nearly 60% of in-house respondents had seen no noticeable savings from their outside counsel's use of generative AI — and of that group, 58% said their firms had not adjusted pricing to reflect the efficiencies. A firm billing by the hour loses revenue as its AI tools get faster; a firm on fixed pricing keeps the productivity gains as margin. Guess which model most firms prefer.
The response is coming: 61% of respondents said they were likely to push for pricing changes at their current firms. The 2026 budget cycle is when AI moves from experiment to line item — not just technology spend, but the price adjustment that technology is supposed to buy.
What This Means for 2026 Budgets
Three benchmarks worth carrying into your next budget meeting. First, if your outside counsel rates rose less than 7%, you beat the market — barely. Second, if more than 60% of your routine litigation and transactional work still goes to your most expensive firms, you are the client the TRI analysts warned about: the one funding record profits without record value. Third, the departments hitting their budgets aren't the ones that negotiated best — they're the ones that moved work. Implementing alternative fee arrangements gave departments a greater than 90% chance of hitting budget targets in the ACC's chief legal officer survey.
Law is the last profession that bills by the mystery. The 2026 numbers suggest the mystery is getting expensive — and that the buyers are finally doing the math.
