AI-driven demand lifted U.S. chip stocks. AMD (AMD.O) jumped over 9% intraday to
a record $613.92, pushing its market cap above $1 trillion; it is viewed as one
of NVIDIA's (NVDA.O) main GPU rivals. AMD is the fourth U.S. chipmaker to exceed
$1 trillion after NVIDIA, Broadcom (AVGO.O) and Micron (MU.O); NVIDIA passed $1
trillion in 2023 and is now the world's most valuable company at over $5
trillion. Most chip names rose Monday: Intel (INTC.O) was up about 11% intraday,
Qualcomm (QCOM.O) gained 4.1%, and the Philadelphia Semiconductor Index rose
2.6% to a one-month high.
