The Roundhill Memory ETF, trading under the ticker DRAM, has crossed $20 billion in assets under management. For a fund that launched on April 2, 2026, that growth trajectory is, to put it mildly, unusual.
To put the pace in context: DRAM hit $1 billion in AUM after just 10 trading days. It reached $6.5 billion within roughly 36 days. Now it sits above $20 billion. Most ETFs spend years trying to crack the $1 billion mark.
What DRAM actually holds
DRAM is the first exchange-traded fund built exclusively around memory chip companies. The fund’s primary holdings include Samsung, SK Hynix, and Micron, the three companies that collectively dominate the global market for DRAM chips, NAND flash storage, and high-bandwidth memory (HBM).
The ETF is actively managed, meaning a portfolio team is making deliberate allocation decisions rather than passively tracking an index. It uses a mix of direct equity positions and derivatives to gain exposure across the memory sector. The expense ratio is 0.65%.
