Global stocks slide as AI spending doubts resurface, oil rallies

Global stock markets declined Thursday as renewed concerns over the sustainability of artificial intelligence infrastructure investments weighed on investor sentiment. The weakness emerged after a major South Korean technology IPO underperformed market expectations, triggering broader questions about the pace and profitability of AI-related capital expenditure across the sector.

The selloff in equities coincided with significant gains in energy markets, where Brent crude oil climbed above $111 per barrel. The price surge was driven by mounting geopolitical risks that have reignited concerns about potential disruptions to global crude supplies.

The divergent movement between equity and commodity markets reflected investor anxiety about competing economic headwinds. While technology stocks face pressure from doubts over AI spending returns, energy markets are drawing support from geopolitical instability and its potential impact on production and supply chains across key oil-producing regions.

The market movements signal a period of heightened uncertainty among global investors, with sentiment shifting away from growth-oriented technology investments toward defensive positioning. Analysts are closely monitoring whether the recent weakness in AI-related valuations will persist or whether investor enthusiasm will resurface as earnings reports filter through.
