Gravity Strikes: The AI Trade Gets Its First Real Gut Check
A global tech sell-off led by AI and chip stocks wipes hundreds of billions in value, as investors finally question how long the boom can outrun gravity.
The numbers landed like a verdict. On Tuesday, the Nasdaq 100 plunged more than 3% and the S&P 500 fell 1.4% as a global sell-off ripped through the AI and chip stocks that have powered the market for two years. South Korea's Kospi closed down 10%, with Samsung and SK Hynix each sliding more than 12%. Nvidia — the world's largest publicly traded company — dropped 4.15%. "Gravity strikes," JPMorgan traders wrote in a morning note, summing up the mood. (NBC News, Reuters)
The spectacle's centerpiece was SpaceX. Just two weeks after its IPO debut at $150, shares had briefly soared past $225 before collapsing — Monday's 17% drop alone erased roughly $400 billion, the second-largest single-day wipeout for any stock on record. By Tuesday the company was pitching a ~$20 billion bond offering on top of the $85 billion it raised at IPO. The whiplash crystallized the day's broader anxiety: valuations that once looked like destiny now look like leverage. (CNBC, NBC News)
Underneath the tape, the fear is structural. Rising borrowing costs — stoked by the Iran war's inflationary drag on the Strait of Hormuz — threaten the cheap capital that funds the AI infrastructure buildout. Analysts at Wedbush framed it as a "gut check moment," insisting the revolution is still "in the third inning." Maybe. But after a year in which memory-chip stocks like Micron and SK Hynix returned 700%+, the market is no longer pricing in only upside. It's pricing in the bill. (NYT, Reuters)
