Chip stocks took a brutal beating on Thursday, and Bloomberg's Ian King says investors are suddenly rethinking how quickly the industry can grow to meet demand. The spark was Qualcomm's latest earnings, where handset chip revenue dropped 26% to $5.14 billion and weak guidance overshadowed growth in car chips and its new data center push. Qualcomm's shares opened about 13% lower, putting the company on track for its worst day since 2020, and Arm also came under pressure. At the worst point, the Philadelphia Semiconductor Index was down as much as 11% and the Nasdaq 100 was off nearly 6%, wiping out trillions of dollars in market value.

The pain in phones is tied to the AI boom itself, because the surge in AI demand is gobbling up memory chips and driving up costs for smartphone makers, who have cut production and trimmed inventories. King's point is that the worry is not a lack of demand but whether the real-world pieces, like power grids and factories, can be built fast enough to meet it. The election added fuel, as some investors fear a Democratic Congress could bring tougher scrutiny of data center buildouts, though that remains a concern rather than a policy. Analysts also noted that big tech is still spending heavily and that the volatility has not yet hit the extremes seen in past capitulations. Whether this is a panic or the start of a longer reset depends on how fast the AI buildout can actually move.
