Tech Stocks Rally as AI Investment Fears Begin to Ease After Historic October Selloff

US equities posted modest gains Monday as investors cautiously returned to technology shares following one of the most severe corrections in the artificial intelligence sector since the boom began, with Wall Street reassessing both the sustainability of AI spending and the financing challenges that have emerged as the industry's next critical bottleneck. The S&P 500 added 0.2% in early trading while Nasdaq-100 futures climbed 1.32%, reversing sharp declines from the prior week when the tech-heavy index fell 4.5% amid a broad erasure of more than $1 trillion in market value across global equities. The sell-off, concentrated between October 13 and 16, was driven by converging pressures: a significant downward revision to OpenAI's revenue trajectory, mounting concerns over debt levels at AI infrastructure firms, and stark warnings from semiconductor executives that capital availability—not chip production capacity—now poses the greatest constraint on continued expansion.
