A surge in chip stocks, led by strong gains in Nvidia and intermittent rallies in Intel and Micron, has driven the S&P 500 and Nasdaq to fresh record highs. Semiconductor momentum lifted both U.S. and European tech sectors, offsetting mixed performance among mega-cap platform names. Positive earnings, AI demand and increased IPO activity in regional chip markets reinforced investor appetite, even as robust inflation data tempered hopes for near-term rate cuts. The trend reflects sector rotation toward hardware and AI-related semiconductor plays, with chipmakers increasingly steering broader equity benchmarks despite episodic profit-taking in large-cap tech names.
Semiconductor strength, led by Intel and other chipmakers, is driving major U.S. indices to record highs and shifting investor allocation toward hardware and AI supply chains. Tech professionals should watch demand signals and client spending that could affect chip design, procurement, and AI infrastructure investments.

U.S. mega-cap tech stocks opened broadly lower in premarket trading on May 15, with Intel plunging more than 5%. Nvidia fell over 3%, Tesla dropped over 2%, and Apple, Amazon, Google (Alphabet) and Meta each declined by more than 1%; Microsoft bucked the trend, rising 0.38%. The moves reflect sector-wide profit-taking or reaction to macro/newsflow affecting large-cap tech names and matter for markets because these companies heavily influence major indices and investor sentiment. Traders and tech investors will watch whether declines persist into the regular session and if any company-specific news or earnings updates drive further volatility.
