U.S. stock futures edged higher Wednesday as investors weighed strong early demand for Meta Platform’s Muse AI agent (software that performs tasks with limited human direction) and awaited a key meeting between U.S. and Chinese leaders later in the week. Muse’s rapid download growth lifted chip stocks and helped push the Nasdaq Composite to record highs, but revived concerns about disruption to financial services, travel and other software-linked industries. Meta CEO Mark Zuckerberg was due to discuss the product at a company conference, with AI safety concerns also in focus. Brent crude remained below $100 a barrel as diplomatic efforts involving Iran raised hopes of easing the nearly seven-month Middle East conflict. Investors also awaited S&P Global’s preliminary September business activity data, with services activity expected at 56.0 and manufacturing at 53.4.
