Chip Stocks Lead Two-Day Rout as Broadcom (AVGO) AI Outlook and Hot Jobs Data Rattle Markets; Arm, Intel, AMD Tumble

Chip stocks led one of the sharpest equity routs of 2026 this week, as a cautious AI outlook from Broadcom (AVGO) collided with a hot May jobs report to drag the sector sharply lower over two sessions. The PHLX/SOXX semiconductor complex fell roughly 10.4% on Friday, with the Nasdaq posting its worst day since April 2025. The damage was concentrated in the AI and CPU names. Arm Holdings (ARM) tumbled 12.8%, Intel (INTC) dropped 11.3% and Advanced Micro Devices (AMD) lost 10.9%. Broadcom itself fell as much as 13%-14% after its report, with Micron (MU) and Marvell (MRVL) also caught in the downdraft. By some estimates, the global chip sector shed well over $1 trillion in market capitalization. The immediate trigger was Broadcom's guidance. Despite an earnings beat and AI revenue that surged roughly 143% year-over-year to about $10.8 billion, the company guided third-quarter AI chip sales to roughly $16 billion, below the ~$17.2 billion analysts expected. Critically, CEO Hock Tan declined to raise the full-year AI semiconductor forecast — a move investors read as a tacit signal that hyperscaler-driven growth may be plateauing. Adding to the unease, Broadcom is reportedly facing share loss at its largest custom-silicon customer, Google, which has begun diversifying its chip suppliers. After pricing the group for perfection, the market punished even record growth that merely failed to accelerate. Macro forces amplified the selling. A much stronger-than-expected May payrolls print — about 172,000 jobs added — pushed Treasury yields higher and revived fears that the Federal Reserve could hold rates higher for longer. High-multiple AI names are especially sensitive to rising discount rates, so the yield spike hit the most richly valued semiconductor stocks hardest. Some economists flagged hiring tied to the U.S.-hosted World Cup, starting June 11, as a possible one-off driver of the surprise gain. The combination exposed a fragile setup: a sector priced for uninterrupted exponential AI demand, suddenly confronting evidence of intensifying competition in custom AI silicon and a less dovish rate path. Memory-chip weakness and concerns over softening smartphone demand compounded the reassessment. For now, the outlook skews cautious. Investors will closely parse upcoming Fed communications; any hawkish tone could extend pressure on AI-levered chip names, while a benign inflation read or reassuring hyperscaler capex commentary could stabilize sentiment. Until then, the rout underscores how much optimism was embedded in chip valuations — and how quickly a single guidance miss can unwind it.
