US stock futures fell on Tuesday as investors worried about oil, interest rates and AI stocks. Higher crude oil prices, rising Treasury yields and growing uncertainty around demand for artificial intelligence technology were the main reasons for the weakness. Investors are also worried that high inflation could force the Federal Reserve to keep raising interest rates, making borrowing more expensive.
