Software and data-services stocks faced heavy selling after a productivity tool for in-house lawyers. The tool was described as automating tasks like contract review and legal briefings. The release sharpened investor concerns about competitive pressure across legal publishing and analytics.
Selling spread quickly across exposed firms with similar revenue models. London Stock Exchange Group Plc fell as much as 10% during the slide. Thomson Reuters Corp. plunged as much as 17% in early trading. CS Disco Inc. sank as much as 14%, while LegalZoom.com Inc. declined about 16%.
European-listed analytics providers also dropped sharply. RELX Plc and Wolters Kluwer NV fell more than 10% during the session. Experian Plc slid about 7% as the sell-off broadened.
The earnings backdrop within software has also looked less supportive than usual. According to reports, only 67% to 71% of software companies in the S&P 500 beat revenue expectations, compared with approximately 83% to 85% across the broader technology sector using the same dataset.
Most software companies beat earnings expectations. However, that did not prevent declines because investors focused on long-term prospects.
The market reaction reflected a specific fear about business models under AI. Investors worry about more competition and greater pricing pressure over time. They also worry that software “moats” look thinner under faster automation.
