Disrupted or Displaced? Anthropic’s Big Bet on Law

Back in 2024, Bill Gates predicted that AI could upend the legal industry by making workers “four times more productive” than they are currently. Cue 2026 and Anthropic’s new Claude plugin could just do that as it aims for legal teams to shift away from simple “legal chatbots” to a robust legal infrastructure. 

Designed specifically for in-house counsel, the tool automates contract reviews, NDA processing, and compliance workflows. By analyzing agreements, flagging risks, and summarizing obligations, it integrates directly into existing legal tech stacks to enhance daily operations. In a profession defined by precision, liability and billable time, the new legal tool by Anthropic promises more than just a productivity boost and more of a structural shift. But does this shift merely enhance the existing legal software ecosystem, or does it begin to displace it altogether?

Legacy jitters

For one, when the plugin dropped, the markets noticed. According to reporting from Business Insider, shares of Thomson Reuters and RELX — the parent company of LexisNexis — both fell roughly 15% in early February following the news. Thomson Reuters and LexisNexis are the legacy institutions of modern legal infrastructure. Their databases, citators, compliance tools, and workflow software sit at the heart of law firms, courts, and in-house legal departments around the world. Though short-lived, the sharp downturn in their fortunes did indicate that investors were rattled by Anthropic’s move, which seemed to take direct aim at the incumbents who have long dominated legal research and compliance databases.

Still, legal software disruption is never as simple as better technology. Law is a low-margin-for-error industry. A hallucinated clause, a misinterpreted regulation, or a missed compliance flag can carry regulatory penalties or malpractice exposure. Major clients in finance, healthcare, and public markets demand reliability, auditability, and explainability.

Daniel Lewis of LegalOn Tech urged a cautious approach. “Far too early to herald this as a major disruption,” he told us. “AI has been getting better quickly, and many new form factors for delivering it to users have emerged in the past couple of years. This is best viewed as another form factor and should be judged by how it competes on the merits.

Lewis believed it best to ask whether the results were accurate, the tool easy to use, and whether it was built on secure and trustworthy content. “These are the questions that legal tech customers will be asking. Preliminary feedback is that this isn’t passing all those questions with flying colors.”

From Smart Contracts hype to AI promise

For those old enough to remember the “smart contracts” discourse, today’s AI exuberance may feel familiar. Blockchain evangelists once promised that code would replace legal drafting and that decentralized protocols would eliminate the need for trusted intermediaries. The idea was seductive: frictionless execution in a world without ambiguity. Lawyers, it was suggested, would be automated away.

Patrick Hicks, Chief Strategy Officer at Legal Karma, drew a sharp distinction between the two. “The hype around smart contracts relied on the myth of a frictionless world — one without grey areas and where legal systems could evolve as fast as technology. That world doesn’t exist. We’ve seen decades of legal tech that has promised to change the world if the world were a little different, focusing on what ‘could be’ rather than what is.”

Anthropic’s innovations are different, Hicks argued, because they offer immediate potential within the complex, high-friction reality of the law today. “That potential is not dependent on changing the fundamentals of our legal system; instead, it reflects an opportunity for meaningful advancement within the system today. This isn’t an innovation that lives in fiction; it’s a tool built for success in the real world.”

Despite this, Hicks also flags a variable that markets may be underpricing: regulators. “What remains to be seen is how regulators respond. Will this be the catalyst that moves regulators past a passive, wait-and-see approach? Anthropic’s new tool has immense potential because it is built for the reality of the system today, but it could also spur the long-overdue regulatory changes needed to build a truly modern one.”

Changing the Experience of Law

Beyond competition and compliance lies a deeper structural shift. Mariano Jurich of Making Sense argues the bottleneck isn’t technology itself but workflow design. “Most law firms today are not limited by a lack of technology; they are constrained by workflows designed for a pre-AI environment. Traditional practice follows a linear path: documents are gathered, lawyers interpret them, and decisions follow. Artificial intelligence reshapes that sequence: information arrives as signals, software performs the first layer of reasoning, attorneys supervise and validate the conclusions, and only then are decisions made. Legal software is therefore moving beyond document storage toward decision support.”

That transition has implications for the nature of the legal experience in the future. “Artificial intelligence will also force changes in how legal value is measured. As the time required to perform tasks drops, software will track risk reduction, outcome probability, and negotiation leverage rather than hours worked. At the same time, clients will gain access to transparent dashboards showing projected costs, settlement ranges, and case trajectories. Legal platforms will become shared intelligence environments between lawyer and client, not internal firm tools.”

“For the longest time, legal was not a sector known for deep technological innovation. Most tools digitized existing processes but did not fundamentally change how legal reasoning or advisory work was delivered,” says Nirbhay Bakshi, CEO of The Precedent. “With the emergence of large language models, this has shifted. For the first time, software can meaningfully ingest, interpret, and generate complex legal text.” That shift, he argues, has exposed legal not as a monolith but as a web of highly specialized workflows, with each substantial enough to sustain its own purpose-built tools.

So did Anthropic just ring the death toll for LegalTech? Probably not — at least not yet. But it may have accelerated a transition already underway: from document repositories to reasoning platforms, from research tools to decision engines, and from legacy dominance to AI-native competition. The legacy databases are no doubt still powerful, but the challengers are nimble, and the deep tech titans have noticed. The deciding factor won’t be hype. It will be about trust, accuracy, integration, and whether AI can operate not just by the letter of the law but also by its spirit.
