Legal Tech Rewind: February 2026, the Claude Crash and the Privilege Split

Legal Tech Rewind is our month-by-month look back at 2026 for in-house legal teams: what happened, why it mattered, and what it looks like with the benefit of hindsight. Published October 2026.

February in one sentence

An AI legal plugin spooked investors in legal data companies, two courts split on whether AI chats are privileged, and in-house teams started demanding a share of their law firms' AI savings.

1. The "Claude Crash"

Anthropic released a legal plugin for Claude Cowork covering contract review, NDA triage and compliance work. In early February, shares in the big legal data companies fell sharply. Canadian Lawyer reported drops of about 14% for both RELX (LexisNexis's parent) and Thomson Reuters, and about 10.5% for Wolters Kluwer. Artificial Lawyer called the market's reaction "irrational."

The incumbents chose partnership over a fight. By the end of the month, Thomson Reuters had confirmed it was building next-gen CoCounsel Legal on Anthropic's Claude and Agent SDK, and said CoCounsel had reached 1 million users in 107 countries. LexisNexis made Lexis+ with Protégé generally available in the US, running on models from Anthropic, Google and OpenAI, and integrated the Cowork legal plugin into Protégé in commercial preview.

Why it mattered: investors were betting that general-purpose AI would replace specialist legal content. The incumbents bet that AI makes authoritative content more valuable.

Since then: the incumbents look right, for now. LexisNexis posted its fastest growth ever in the first half, with 90% of new business coming from AI-related products, and Thomson Reuters raised its guidance. The frontier labs kept coming anyway: Claude for Legal in May, Gemini Enterprise for Legal in August, Astra for Law in September, Copilot for Legal in October.

2. Two courts split on AI and privilege

• United States v. Heppner (S.D.N.Y.): Judge Jed Rakoff ruled from the bench on February 10, with a written opinion on February 17, that a criminal defendant's chats with Claude about his legal situation were neither privileged nor work product. Claude isn't a lawyer, the consumer privacy terms undercut confidentiality, and the chats weren't made at counsel's direction.
• Warner v. Gilbarco (E.D. Mich.): the same day, a court held that a pro se plaintiff's ChatGPT use was protected work product and not waived, because AI programs "are tools, not persons."

Why it mattered: your executives are typing legal questions into AI tools. Whether those chats end up in discovery may depend on which tool, whose terms, and whether counsel directed the work.

Since then: courts in Texas and New York sided with Warner in June, but Heppner remains the warning case. We turned it into a problem and solution post and a one-page AI acceptable use policy.

3. Clients asked: who keeps the AI savings?

Two February surveys put numbers on a growing frustration:

• Juro's State of In-House 2026 (130+ senior in-house lawyers): 44% think they could halve outside counsel spend and still manage risk, 68% say more than 10% of work sent to firms could be brought in-house with AI, and 73% of those who knew their firm used AI believe the firm keeps most of the savings. Juro is a vendor, so treat this as directional.
• Thomson Reuters Institute AI in Professional Services Report (1,500+ respondents): organization-wide AI use rose to 40% from 22%, but only 18% track AI ROI. More than half of corporate legal departments want their firms to use AI on their matters, but fewer than a third know whether they do.

Since then: Thomson Reuters' July research found only 6% of corporate respondents say most of their firms deliver AI productivity gains, and Deloitte found 58% of GCs say firms rarely or never raise AI benefits. The pressure didn't go away. It grew.

4. Harvey and LegalOn went after in-house

Harvey was reported to be in talks to raise $200 million at an $11 billion valuation (announced in March), with about $190 million in annual recurring revenue at the end of 2025. Harvey also made Anthropic's new Claude Opus 4.6 available on its platform, citing a 90.2% score on its BigLaw Bench. LegalOn unveiled a family of five agents specifically for in-house teams (Playbook, Intake, Translate, Triage and Draft), rolling out in stages.

Thomson Reuters bought Noetica, which benchmarks deal terms across more than 1.5 billion terms, to fold into CoCounsel.

Why it mattered: deal-term benchmarking and in-house agents are aimed squarely at corporate legal work. The vendor market was shifting from law firms to you.

5. More sanctions for fake citations

In Lexos Media IP v. Overstock (D. Kan.), a court imposed $12,000 in Rule 11 sanctions for AI-generated fake citations, split among several lawyers.

Why it mattered: by February, "the AI made it up" had stopped being a novel excuse and become a routine sanction.

6. The EU AI Act timeline wobbled

The European Commission missed its February 2 deadline to publish guidance on classifying high-risk AI systems, while the proposed Digital Omnibus delay worked its way through Parliament's committees.

Since then: the delay passed and took effect in July, pushing high-risk obligations to December 2027 and August 2028. Transparency duties still started August 2, 2026.

What to do with February's lessons now

• Write the privilege rules into your AI policy. Legal questions go to enterprise tools, used at counsel's direction. Consumer AI tools are off-limits for anything touching a dispute.
• Ask your firms about AI on your matters. What tools, what savings, and how they show up on the invoice. Enforce it with e-billing and spend management and benchmark with legal spend analytics.
• Check what your research subscription includes. Lexis+ with Protégé and CoCounsel now do a lot more than research. Start with legal research and practical guidance.
• Measure AI ROI. Only 18% do. Pick two metrics (turnaround time and outside counsel spend avoided) and start tracking.

February's lesson: the market panicked about AI replacing legal content. The real question was always who captures the savings, and that should be you.
