Shares of Wolters Kluwer and Relx, major players in professional services, experienced a downturn following the announcement of an AI-powered legal tool by Anthropic. In morning trading, the Dutch company saw its shares decrease by over 7%, while those in the U.K. fell by 3.2%. This reaction highlights the growing impact of AI on established industries.

Anthropic's new plugin is designed for in-house legal teams and automates various legal workflows, including contract review and compliance. Though the tool is intended to assist, not replace legal professionals, the market is clearly reacting to the potential for AI to disrupt traditional legal services. This is a rapidly evolving space, and investors are carefully watching.

The development underscores the broader trend of AI integration across professional sectors. Anthropic is also rolling out additional AI tools for sales and customer support. The market's response to these announcements suggests a heightened sensitivity to the competitive implications of AI advancements, particularly for companies reliant on information services.
