Global Markets Reprice AI Demand After Chipmaker Rout

A report on slowing AI memory chip production sent shockwaves through global markets, prompting investors to question whether demand for AI infrastructure is as insatiable as previously assumed.

The report, from SK Hynix, raised doubts about the demand from large cloud and tech companies, known as hyperscalers, which had fueled a massive rally in chipmakers. The news triggered a selloff that was not contained to South Korea, where SK Hynix and Samsung Electronics each shed more than 10% intraday.

The damage spread globally, with the Nasdaq 100 falling roughly 2.9%, and the S&P 500 opening approximately 1.3% lower. Nvidia and Micron joined their Korean counterparts in the red, reinforcing the message that this was a sector-wide repricing, not a localized shock.

The VIX, Wall Street's fear gauge, spiked above 20, signaling that options traders are bracing for meaningfully elevated near-term volatility. Bitcoin also fell toward the $63,000 level as broader market sentiment soured, illustrating the dynamic that crypto investors have become familiar with over the past few years.
