U.S. stock futures were mixed Tuesday after Wall Street closed lower the previous session, with Dow Jones and S&P 500 futures slipping while Nasdaq 100 futures inched higher. Risk sentiment was shaped by a 2.52% rise in Brent crude futures to $89.93 after President Donald Trump demanded Iran pay compensation for historical damages and deaths, a move Reuters said reduced hopes for a deal to reopen the Strait of Hormuz, a critical oil shipping lane. Treasury yields also remained elevated, with the 10-year at 4.73% and the two-year at 4.03%, while CME Group’s FedWatch tool showed markets pricing a 51.9% chance of a Federal Reserve rate hike at the September meeting. In premarket trading, Rocket Lab fell despite record revenue, a $2.36 billion backlog and strong third-quarter guidance, as investors focused on a wider-than-expected loss and uncertainty around the Neutron rocket launch timeline. Plug Power rose after beating revenue and adjusted loss expectations and improving gross margin, while AST SpaceMobile slipped after missing analyst estimates. CoreWeave and Super Micro Computer were also in focus ahead of earnings. Analysts cited in the report said recent labor-market softness may reflect a transition rather than recession, and Professor Jeremy Siegel said the Fed may struggle to justify a September hike unless oil prices rise sharply.
