Why Your Competitor Pays Half What You Do: Decoding Legal Research AI Pricing 

By Ken Purce, Founder & Principal | February 2026 

AI upgrades from Westlaw and LexisNexis are being priced as a percentage of each firm’s current contract — which means firms already paying above market aren’t just absorbing an upgrade cost. They’re compounding an existing problem. Two firms of identical size, using identical products, can easily end up $280,000 apart annually — and $840,000 apart over a three-year term. 

This white paper breaks down exactly how that happens, why the market remains so opaque, and what the firms getting the best outcomes are doing differently before they enter any AI upgrade conversation.
