Nasdaq 100 futures fell 2.8% on Tuesday as a global sell-off in memory chipmakers fueled skepticism regarding the sustainability of the artificial intelligence investment boom. According to data from Bloomberg, the rout spread from South Korea, where the Kospi index dropped 10%, to US premarket trading, where Micron shares slid 10% and SpaceX market value dipped toward the $2 trillion threshold.
Why are tech stocks facing a global sell-off?
The decline in tech valuations stems from mounting concerns that the AI sector is overstretched. According to AFP, South Korean chip giants SK Hynix and Samsung Electronics both saw their shares sink more than 12% on Tuesday. This ripple effect hit Wall Street, where Nasdaq 100 futures plummeted 2.8% and S&P 500 contracts dropped 1.4%. Investors are now looking to Micron’s upcoming earnings report for a clearer signal on whether memory demand can justify recent record-high valuations.
SpaceX has shed more than $600 billion in market value over three sessions. Monday’s single-session decline of $400 billion ranks as the second-largest loss in history, trailing only Nvidia’s $590 billion plunge in the previous year, according to Bloomberg.
How is the SpaceX valuation shift impacting markets?
SpaceX shares dropped 5% in premarket trading, putting the company on track to fall below a $2 trillion market capitalization. Bloomberg reports that the stock price has dipped to approximately $147, sliding below its initial $150 opening price. This decline follows three consecutive days of losses for the firm, contributing to the broader pressure on the tech-heavy Nasdaq 100 index.

Are Chinese markets entering a bear phase?
Chinese stocks listed in Hong Kong have entered a bear market, defined by a drop of more than 20% from recent peaks. Bloomberg reports that the Hang Seng China Enterprises index fell 1.8%, while the MSCI China index slid 2.2%. Analysts attribute this downturn to weak consumer spending and fading investor confidence in major e-commerce firms like Alibaba and Tencent.
What is the status of US-Iran oil negotiations?
Oil prices stabilized near $78 a barrel as peace talks between the US and Iran showed signs of progress. According to Bloomberg, the US issued a 60-day waiver on oil sanctions, granting Iran an economic lifeline and allowing for the sale of petroleum products. While both nations noted progress in Switzerland, discrepancies persist; Vice President JD Vance claimed Iran agreed to nuclear inspections, a statement Tehran has disputed.
Pro Tip: Monitoring Market Volatility
During periods of tech-sector instability, analysts often monitor the “volatility index” (VIX) and sector-specific earnings. Keep a close watch on Micron’s upcoming report, as it serves as a critical bellwether for the semiconductor industry’s health.
