US equity markets opened lower on Friday, with broad-based selling pressure reflecting growing investor caution regarding the capital expenditure commitments of major technology firms.
The decline marks a continuation of the sentiment shift that has begun to erode the momentum of the artificial intelligence rally that has dominated Wall Street for months.
Skepticism is mounting over the sustainability of current valuations in the technology sector, as traders question whether the massive infrastructure investments will yield commensurate returns in the near term.
This repricing reflects a broader reassessment of risk, moving beyond isolated stock movements to a sector-wide caution.
The latest session follows a similar downturn earlier in the week, when US markets also opened lower amid signs that the AI-driven bull run was losing steam.
The recurring weakness suggests that the market is no longer blindly accepting growth narratives without rigorous scrutiny of underlying fundamentals and capital efficiency.
