Dow Jones| Nasdaq | S&P 500 | US Stock Market Today | Live: US stock futures mixed ahead of SK Hynix listing; Middle East in focus

US stock futures traded mixed as investors awaited SK Hynix's blockbuster Nasdaq debut, which raised about $26.5 billion and signaled continued momentum in the semiconductor upcycle. Chip stocks including Intel and Micron came under pressure on valuation concerns, while Delta Air Lines gained on a stronger-than-expected Q3 profit forecast and crypto-linked names like Coinbase and Riot Platforms advanced with bitcoin. Investor sentiment stayed fragile amid escalating Middle East tensions following Iranian strikes on US military infrastructure in Gulf states, raising worries about energy-driven inflation.
