Chip stocks got hammered on AI demand fears, erasing roughly 500 billion dollars of market value.
What happened
Semiconductor stocks fell sharply as fear spread that the artificial intelligence spending wave might slow. The drop wiped out roughly 500 billion dollars of market value across the sector in a single session. The move came even as Broadcom's CEO said demand remains robust and is not cracking.
Why it matters
The chip sector has become the market's single largest bet on AI. A sustained pullback hits funds and retail investors loaded on the theme because semiconductor orders are treated as a leading signal for data center buildout, cloud revenue, and enterprise software license growth.
The case against
Broadcom's own chief says the end customer pipeline looks solid, which flatly contradicts the fear that drove the sell-off. Government bond yields are still rising and oil prices just surged 11 percent in a week, so the pressure may be more about higher rates and geopolitics than any real halt in AI orders.
What settles it
Whether Broadcom or another major chip maker cuts forward revenue guidance at its next earnings report.
