U.S. stock futures rise as Nvidia earnings beat boosts AI optimism

U.S. stock futures rose Wednesday night after Nvidia's quarterly results beat expectations, renewing investor enthusiasm for artificial intelligence while hotter-than-expected inflation kept Fed policy concerns in focus. S&P 500 futures gained 0.5%, Nasdaq 100 futures climbed 0.9%, and Dow futures edged up 0.3%. Nvidia shares jumped over 5% in after-hours trading as revenue more than doubled year-over-year, with data-center revenue surging 117% and a forecast of about 70% growth for fiscal 2028. The earnings boost followed a slightly lower Wall Street close Wednesday, with the PCE price index rising 3.7% annually in July, above the 3.6% estimate. Salesforce surged 13% after strong results, CrowdStrike jumped 10%, while HP dropped 9% on declining PC shipments.
