Wall Street Futures Slide as Oracle's Forecast Revives AI Bubble Fears

U.S. stock index futures tumbled on Thursday after Oracle Corporation(SY:ORCL) delivered disappointing quarterly forecasts and announced a staggering $15 billion increase in annual spending, reigniting concerns about whether the artificial intelligence infrastructure boom is built on sustainable economics or destined to collapse like the dot-com bubble of the early 2000s.

Oracle plummeted 12% in premarket trading after its quarterly projections fell short of analyst estimates, with management revealing that annual spending would surge by $15 billion compared with earlier expectations. The cloud computing giant, which gained prominence earlier this year through deals to build AI cloud data centers for OpenAI, now faces its worst quarterly performance since mid-2002 as investors question whether debt-financed AI expansion represents sound strategy or reckless speculation.
