Memory chips now generate 50% to 55% of semiconductor industry revenue, up from roughly 20% to 30% historically, as artificial-intelligence data centers drive demand for DRAM, NAND and high-bandwidth memory. Susquehanna analyst Mehdi Hosseini expects global semiconductor revenue to reach roughly $1.5 trillion this year, with memory the primary growth driver. He forecasts DRAM prices will rise 50% in the third quarter and 20% in the fourth, while NAND prices increase 60% and 25%, respectively. Memory-related stocks rallied in New York, with Micron up 2.8%, SanDisk 1.5% and SK Hynix’s American depositary receipts 7.1% on the 9th. TrendForce expects DRAM and NAND to absorb 47% of major cloud providers’ capital spending this year and 68% in 2027, while Omdia forecasts memory will represent more than half of semiconductor revenue in 2026. Micron’s DRAM revenue rose 65.5% to $36 billion in the calendar second quarter, and the company has started high-volume HBM4 shipments. The expansion remains exposed to memory’s traditional boom-and-bust cycle and intensifying competition from China’s CXMT.
