Micron Leads $350B AI Semiconductor Rout After Broadcom Guidance Miss

What happened: Micron (MU) shares fell 7.74% to $996.00 on June 4, closing below $1,000 for the first time in its recent run. The drop followed Broadcom's (AVGO) Q2 results, which, despite being strong overall, included a Q3 AI semiconductor revenue guide of $16B—missing consensus expectations of $17.2B. Broadcom shares fell 12.6%, wiping out ~$280B in market cap. The Philadelphia Semiconductor Index dropped 5.21%, with sector-wide losses estimated at ~$350B. Micron, up 271% year-to-date before the selloff, was particularly exposed due to its role as a key HBM supplier for AI accelerators.

Why it matters: The selloff was driven by sentiment and multiple compression rather than a fundamental demand miss. The AI semiconductor thesis remains intact, but the event underscores the sector's vulnerability to guidance downgrades and macro risk-off. The rout in AI equities fed directly into Friday's broader crypto and tech market declines.
