Wall Street dipped again Thursday, dragged down by tech stocks as worries resurfaced over the costs tied to AI development, with Alphabet and Qualcomm leading the declines. At 9:41 a.m. ET, the Dow was off 0.56%, the S&P 500 had fallen 0.51%, and the Nasdaq slipped 0.50%. Alphabet dropped 2.6%, while Qualcomm plunged about 8%. Melissa Brown from SimCorp called the AI trade “perhaps the extinguisher this year.” Concerns center on capital spending — or “capex” as traders call it — the money firms pump into data centers, chips, and servers to build and operate AI models. Alphabet told investors it plans to spend between $175 billion and $185 billion on capex in 2026. CEO Sundar Pichai said, “We are seeing our AI investments and infrastructure drive revenue and growth across the board.”
