Law firm technology spending surged 9.7% in 2025 — the fastest growth the industry has likely ever seen, according to the Thomson Reuters State of the Legal Market report.
Knowledge management budgets climbed even faster at 10.5%. Westlaw and LexisNexis are pushing hard to migrate firms to their AI offerings. Westlaw has moved from Precision to its new Advantage platform with CoCounsel and Deep Research agentic AI capabilities. Lexis has expanded its suite with Protégé and Protégé General AI.
The technology is real. The capabilities are genuinely useful. The pricing, however, is where things get ugly.
The Percentage Trap Nobody Talks About
AI upgrades are typically framed as a percentage increase over your current contract — sometimes as high as 50%. Sounds simple enough. Here’s what they don’t tell you: that percentage applies regardless of whether your existing contract is above or below market.
After more than 20 years inside and negotiating against these vendors, I can tell you: two firms of identical size, in the same market, using the same products, routinely pay vastly different amounts. The gap can be 40–50% or more. That’s not a typo. There are no published rate cards for enterprise contracts. Pricing is negotiated firm by firm, and the vendors hold an enormous information advantage — they know what every firm pays, but no firm knows what any other firm pays.
Now apply a 40% AI upgrade to two identically sized firms. Firm A, at market rate, goes from $400,000 to $560,000. Firm B, already 50% above market, goes from $600,000 to $840,000. Same product. Same firm profile. A $280,000 annual gap — compounding to $840,000 over a standard three-year term. Firm B isn’t just paying for AI. They’re paying a penalty on a penalty. And that inflated number becomes the baseline for every future renewal.
The Double-Upgrade Hit
It gets worse. Many firms absorbed a 30%+ increase just two or three years ago to move from Westlaw Edge to Precision. Then, in August 2025, Thomson Reuters introduced Westlaw Advantage — described as the “final” version of Westlaw — and those same firms now face another round of comparable increases.
Two major upgrades in under three years, each layered on top of the last. A firm that started at $500,000 for Edge, absorbed a 30% increase for Precision ($650,000), and now faces another 35–40% for Advantage is looking at annual costs approaching $900,000 — nearly double where they started. A competitor who held off on Precision and negotiated directly into Advantage from a better base position may be paying $600,000 or less for functionally equivalent access.
That’s a $300,000 annual gap between two firms that made different timing decisions — not different product decisions. Over a three-year contract, that’s nearly a million dollars.
Why This Matters More in 2026 Than It Ever Has
GC spending sentiment is dropping toward pandemic-era lows. Clients are moving work downstream.
With Am Law 100 standard rates breaking $1,000 per hour and everyone else averaging around $600, GCs are doing the math and shifting work. Every dollar a firm overpays on infrastructure either erodes margins or gets passed to clients who are already voting with their feet.
In that environment, locking into an above-market research contract for three years isn’t a minor oversight. It’s a structural cost disadvantage that compounds with every renewal.
The Fix Is Straightforward (If You Do It First)
AI upgrades are negotiable. Every legal research contract always has been. But the leverage shifts entirely based on one thing: whether you know where your current rate sits relative to market before you start the conversation.
If you’re already above market, the first negotiation isn’t about AI — it’s about correcting your base. Separate that conversation from the upgrade conversation. Don’t accept the framing that the AI premium is simply a percentage applied to your current deal.
If your vendor is creating artificial urgency with expiring offers, that’s a signal to slow down, not speed up. Firms that take the time to evaluate their position consistently achieve better outcomes. And if you haven’t audited what you’re actually using versus what you’re paying for, the upgrade conversation is exactly the wrong time to find out you’ve been subsidizing products nobody touches.
The firms getting the best deals right now walk into the negotiation already knowing the answer to the only question that matters: is my current contract at, above, or below market? Get the base right today, and every future negotiation starts from a stronger position. The compounding works in both directions.
