Micron and the relentless memory-stock rally are pushing the stock market to new highs - Business Insider

Recent strong performance by Micron Technology has driven a rally in the memory chip sector, contributing to fresh record highs across major global indices. Amid the rapid advancement of artificial in... Read original →

The AI compute arms race is thrusting memory chips from supporting actors into the spotlight. Surging demand for HBM and DDR5 isn’t just pushing Micron and SK Hynix to near-full capacity—it’s forcing upstream equipment makers to accelerate EUV and advanced packaging, while simultaneously elevating optical interconnects as Lumentum and Ciena address GPU cluster bandwidth bottlenecks. Geopolitically, U.S. export controls now targeting 1β-node DRAM are compelling Taiwan, China and mainland Chinese firms to fast-track domestic alternatives, inflating compliance costs and supply chain redundancy. With Micron nearing a $100B market cap, Samsung may abandon price wars to bet on CXL-based memory pooling, while Western Digital and Kioxia risk marginalization without QLC NAND yield breakthroughs. Over the next 18 months, AI-driven 'compute-memory co-design' will redefine data centers, potentially making memory bandwidth over 30% of total system cost—ushering in a decisive industry shakeout.
