Roundhill Memory ETF (DRAM) Hits $6.5 Billion in Record 27 Days, Fueled by AI Chip Boom

The Roundhill Memory ETF (DRAM) accumulated $6.5 billion in assets in just 27 trading days, the fastest ramp ever for an exchange-traded fund, eclipsing the 30-day mark set by BlackRock’s spot bitcoin ETF. The fund later breached $10 billion in about six weeks. On Wednesday, May 27, 2026, DRAM shares surged 14.56%, pushing cumulative gains since listing to 118.7%. The rally was driven by SK Hynix, Samsung Electronics and Micron Technology — the world’s three biggest memory-chip makers — each now valued above $1 trillion. Micron and SanDisk have soared 214% and over 569% year-to-date, respectively. UBS analyst Timothy Arcuri lifted Micron’s price target to $1,625, the highest on Wall Street, predicting DRAM shortages until Q2 2028. Barclays raised its SanDisk target to $2,300, while Nomura upgraded Samsung and SK Hynix. Analysts say AI data-center demand is transforming memory cycles into a structural, multiyear upswing.
