Wall Street experienced a broad decline, primarily driven by investor concerns over AI increasing competition for software makers, leading to significant drops in tech stocks like Nvidia and Microsoft. Additionally, healthcare stocks were pressured by Novo Nordisk's sales warning, while PayPal's profit forecast below estimates caused a substantial slump in its shares.
Wall Street ended sharply lower on Tuesday, primarily due to investor worries about Artificial Intelligence (AI) creating more competition for software makers. This concern was partly fueled by Anthropic's launch of a legal tool for its Claude AI chatbot. Major tech companies like Nvidia, Microsoft, Alphabet Inc., and Amazon (company) saw their stocks fall. Several software companies, including Salesforce, Datadog, Adobe Inc., Synopsys, Atlassian, and Intuit, experienced significant declines, with Intuit slumping 11%. In contrast, Palantir rallied after strong quarterly results. The S&P 500 software and services index fell for a fifth consecutive day. Beyond tech, healthcare stocks also faced pressure, with Novo Nordisk's US-listed shares plummeting nearly 15% after a sales warning, impacting rivals like Eli Lilly and Company and Structure Therapeutics. Meanwhile, Walmart climbed to a $1 trillion market value, and PayPal slumped 20% after a disappointing profit forecast. The S&P 500, Nasdaq Composite, and Dow Jones Industrial Average all closed lower. Other corporate earnings from Pfizer, Merck & Co., and PepsiCo also contributed to the day's market activity, alongside news of a procedural hurdle cleared for legislation to end a United States government shutdown.
