US stocks fall at open on tech selloff as concerns about hawkish Fed, AI spending mount

US equities opened sharply lower led by a tech selloff, with the Nasdaq Composite falling about 2.36 percent or 616 points to 25,549, while the S&P 500 dropped 1.42 percent to 7,366 and the Dow Jones slipped marginally by 23 points. Concerns over a hawkish Federal Reserve stance and the sustainability of heavy AI-related capital spending by technology companies triggered the selloff, with the tech-heavy Nasdaq bearing the brunt. The weakness in US markets is likely to weigh on global risk sentiment, including Indian indices tracking the gap-down opening.
