# BUZZ-US chip stocks fall as rate-hike fears raise AI spending concerns

US semiconductor shares fall premarket, as rising bond yields and Fed rate-hike concerns threaten to raise borrowing costs and curb AI infrastructure spending

Philadelphia Semiconductor Index (.SOX) declined 4.3% to its lowest level in about a month in the prior session; stock has been declining since October 7

Micron (MU.O) down 4.3%, Western Digital (WDC.O) down 5.6% and Sandisk (SNDK.O) down 5.3%

Nvidia (NVDA.O) slips 1.7%, Broadcom (AVGO.O) slides 1.6%, Intel (INTC.O) down 3.8%, Qualcomm (QCOM.O) falls 1.8% and Advanced Micro Devices (AMD.O) down 3.4%

Media reports this week that Chinese memory chipmaker CXMT has made “key progress” on a new cell architecture aimed at increasing memory density also pressured global chip stocks

Despite the selloff, the Philadelphia chips index remains up about 65% so far this year, supported by expectations for strong AI-related demand
