Summary: Anthropic has released an updated version of its Claude AI, including a new plug-in designed to perform legal analysis and enterprise tasks such as generating presentations and handling knowledge work. Although the release was relatively modest, it triggered sharp declines in the share prices of major legal data and software companies, with firms such as Thomson Reuters and RELX seeing double-digit drops as investors reassessed the potential impact of AI on traditional business models. Analysts describe the market’s reaction as aggressively searching for sectors vulnerable to AI disruption. Anthropic and some legal software executives argue that the new tools are not direct replacements for established legal platforms, but scepticism remains. The market’s response has raised broader questions about the future competitive landscape for AI tools in professional services.
