The memory chip sector is experiencing a significant pre-market rally, with the DRAM ETF up over 7%. This move is attributed to reports of server DDR5 memory prices surging 15% to 23% in August. This price hike is part of a broader trend of soaring memory costs throughout 2026, driven by an AI-fueled demand boom for high-bandwidth memory (HBM) and enterprise SSDs, leading to a supply shortage. Major manufacturers are reallocating production to these high-margin AI products, further tightening supply.
