The launch of a new AI automation tool by Anthropic, aimed at enhancing efficiency in the legal sector, has triggered a significant market reaction. This tool, integrated into the company’s Cowork features, focuses on automating tasks such as contract reviews and legal briefings. Despite its advanced capabilities, Anthropic insists that outputs must still be vetted by qualified attorneys, ensuring oversight in legal work.
Following the announcement, shares of several legal software and analytics firms saw dramatic declines, with RELX Plc and Wolters Kluwer NV each experiencing drops exceeding 10%. Other companies like Experian Plc fell by 9%, while stocks of the London Stock Exchange Group, Thomson Reuters Corp., Legalzoom.com Inc., and FactSet Research Systems Inc. also slid significantly. The iShares Expanded Tech-Software Sector ETF decreased by 4.4%, alongside a nearly 7% drop in a group of European stocks flagged by UBS Group AG as susceptible to AI disruption.
Analysts are concerned that Anthropic’s entry will escalate competition in the already crowded legal AI market, which includes notable startups such as Harvey AI and Legora. With Harvey AI valued at $5 billion and Legora at $1.8 billion, the competitive landscape is intensifying, particularly as Anthropic leverages its unique position as a developer of proprietary AI models.
