The launch of new artificial intelligence tools by AI developer Anthropic has triggered a significant selloff across U.S. and European data analytics, software, and professional services companies. Investors fear impending disruption from AI that can automate complex tasks, directly impacting companies once seen as beneficiaries of the AI era.
The market reaction was severe, with Toronto-based Thomson Reuters slumping nearly 18 percent, marking its biggest daily loss on record. In Europe, legal analytics providers RELX and Wolters Kluwer fell 14 percent and 13 percent respectively. The selloff extended to other firms including Factset Research, down 10.5 percent, and LegalZoom, which plunged 19.7 percent. Broader market indices like the S&P 500 and Nasdaq also closed lower.
Analysts attribute the selloff to Anthropic's new plug-ins for its Claude AI agent, which target the legal, sales, and data analysis sectors. This technological advance challenges the core business models of incumbent firms. Investors are aggressively repricing these sectors as the rapid advancement of AI makes their long-term valuations harder to defend. The fear is that AI tools will allow businesses to accomplish more with fewer staff, threatening traditional per-user software licensing models.
The market is currently grappling with the structural implications of advanced AI. The recent events highlight a shift in investor sentiment, where companies once expected to leverage AI are now seen as vulnerable. The focus going forward will be on how established firms adapt their strategies to compete with specialized and more efficient AI tools.
Q: What caused the selloff in software and data analytics stocks?
A: The launch of new AI tools by Anthropic, designed to automate complex tasks in legal and data analysis, sparked investor fears of industry-wide disruption.
Q: Which companies were most affected by this news?
A: Thomson Reuters experienced a record drop of nearly 18 percent. Other professional services firms like RELX, Wolters Kluwer, and LegalZoom also saw significant declines.
