Update: US Equity Indexes Jump as CoreWeave's Strong Q3 Results Boost AI Trade

03:57 PM EST, 11/11/2026 (MT Newswires) -- (Updates with index/price moves and geopolitical news from the first paragraph.) US equity indexes jumped after CoreWeave's (CRWV) Q3 earnings bolstered the outlook for demand from the artificial intelligence infrastructure buildout, sparking a rally in semiconductors and related industries. The Nasdaq Composite surged 1.7% to 25,488.25, the S&P 500 advanced 1.4% to 7,642.06, and the Dow Jones Industrial Average rose 0.5% to 52,486.64 ahead of Wednesday's close. Technology, energy, and industrials topped the outperformers, with all but two sectors rising. CoreWeave soared 24%, the Nasdaq's biggest outperformer, after the cloud-computing firm that rents out AI infrastructure outlined plans to finance its business expansion through loans tied to customer contracts and prepayments, reducing its reliance on unsecured borrowing. CoreWeave's Q3 results beat expectations for sales and adjusted operating income, and a strong full-year outlook and management's comments on 2027 funding sources reassured investors about the firm's financing plans, Morgan Stanley said in a note. S&P 500 "rebounded after strong results from cloud computing firm CoreWeave helped ease concerns over excessive AI spending, lifting investor sentiment," a D.A. Davidson research note said. Of the 20 top-performing stocks intraday with market capitalization exceeding $200 billion each, all but one were technology firms, according to Finviz-compiled data. Micron Technology (MU) and Arm (ARM), up about 12% each, were among the top three leaders in these mega-caps as CoreWeave's results reinforced the strong-demand thesis surrounding the AI plays. Of the tech giants in this category, more than half were either chipmakers or providers of semiconductor equipment and materials. The iShares PHLX Semiconductor Exchange Traded Fund, with about $43.67 billion in assets under management, surged 6.4%, reflecting the bullish sentiment in the so-called AI trade.
