Roundhill Memory ETF DRAM becomes fastest-growing ETF launch as retail buyers chase chip exposure

Roundhill’s Memory ETF (DRAM) has gathered more than $6 billion in assets since its April 02, 2026, launch, making it the fastest-growing ETF debut on record, Reuters reported May 13, 2026, citing market data and analysts. The fund reached $1 billion in assets in 10 trading days and took in $1 billion of net inflows on May 08, 2026, after a rally in global chipmakers. Analysts said investors are using DRAM as a simpler way to gain exposure to memory-chip demand tied to artificial intelligence data centers, including South Korea’s SK Hynix and Samsung Electronics, along with Micron and other Asian suppliers. Vanda Research said retail investors bought $55 million of DRAM on May 11, 2026, the largest daily retail inflow since launch. The fund fell 7% on May 12, 2026, as chip stocks retreated, underscoring concerns that the trade may be overextended despite an intact uptrend.
