Anthropic filed confidential IPO papers on Monday, putting the maker of the Claude chatbot on a path to beat ChatGPT parent OpenAI to a public listing, according to the Wall Street Journal’s Heard on the Street column. The filing positions Anthropic as the first major artificial-intelligence company to pursue a stock-market debut, and research cited by the Journal indicates that first movers in industry cluster IPOs tend to outperform later entrants.
The announcement arrived alongside Nvidia’s move into the personal-computer market, and together the two developments lifted AI-linked technology stocks across the board. Nvidia shares jumped more than 6%. Microsoft gained 2.3%. Dell, which manufactures both AI-enabled PCs and servers, surged nearly 11%.
Arm Holdings rose nearly 16% on investor expectations that Nvidia’s entry into the PC market will boost demand for Arm’s basic chip designs, which compete with the x86 architecture produced by Intel and AMD.
The AI-driven buying was tempered early in the trading session by fresh skirmishes between the U.S. and Iran. President Trump later said that “all shooting will stop” between Israel and Hezbollah.
The Dow Jones Industrial Average closed up 46 points at 51,079. The S&P 500 rose 0.3%. The Nasdaq gained 0.4%.
