Wall Street is in the grip of disruption worries from AI. It first started with investors dumping shares of software companies but soon spread to sectors seen as vulnerable to automation, driving sharp losses in U.S. stocks this week. The AI scare trade did not spare even sectors such as private credit, real estate brokers, data analytics, legal services and insurers. Global tech stocks took the hit after Anthropic unveiled a legal AI plug-in. But soon the investor unease deepened following a flurry of AI model upgrades and fresh releases.
