US stock futures were little changed Wednesday as investors waited for the consumer price index report, a key inflation gauge that could influence the Federal Reserve’s next rate decision. Producer inflation data follows on Thursday. Markets are split on whether the Fed will raise rates by 25 basis points (0.25 percentage point) in September after holding them unchanged in July, with higher oil prices adding to expectations for a more hawkish stance. In extended trading, CoreWeave surged more than 14% after the artificial intelligence spending boom improved its sales outlook, while Super Micro Computer climbed more than 7% after the data center infrastructure provider gave upbeat first-quarter earnings and revenue guidance. Investors are also watching Wednesday earnings from Cisco Systems, Cerebras and Enersys, among others.
