Roundhill Investments' Memory ETF, trading under the ticker DRAM, has amassed $6.5 billion in assets under management within just 36 days of its launch, marking one of the fastest asset-gathering periods in the ETF industry. The fund, which debuted on April 2, 2026, has capitalized on surging investor demand for exposure to memory chip manufacturers critical to the artificial intelligence hardware supply chain.
As of May 12, 2026, shares of DRAM were trading at $52.44 in New York, reflecting a decline of approximately 4.8% from recent highs. The fund's rapid ascent underscores a shift in the AI rally away from traditional chip giants like Nvidia toward tighter segments of the supply chain, particularly high-bandwidth memory (HBM) producers. DRAM focuses on companies producing HBM, NAND storage, and dynamic random-access memory, all essential for data transfer in AI processors.
The fund's portfolio is heavily concentrated, with Samsung Electronics, SK Hynix, and Micron Technology each accounting for nearly 24% of holdings. Combined, these three firms represent about 75% of the ETF's assets. Year-to-date performance for these stocks has been stellar: Micron surged over 175%, SK Hynix climbed roughly 190%, and Samsung added approximately 140%. SanDisk, a smaller position, soared 560%.
Retail investors have been a major driver of DRAM's growth. According to Vanda Research, the fund attracted more than $150 million in retail net buying in May alone, outpacing flows into Nvidia, Micron, and Palantir. CFRA Research's Aniket Ullal described the launch as an "incredibly successful" debut, noting it is the first ETF to zero in on HBM stocks.
The ETF issuer response has been swift. A preliminary SEC filing from May 8 reveals that Themes ETF Trust plans to launch the Leverage Shares 2X Long Memory Daily ETF, designed to deliver double the daily returns of DRAM. This leveraged product is tailored for short-term traders and carries heightened risks, including potential losses in volatile markets.
Despite the enthusiasm, risks remain. Nasdaq's trading circular highlights concentration risk, sector exposure, and the possibility that shares may deviate from net asset value. The fund's heavy weighting in a few names means that any downturn in memory prices or AI data-center spending could lead to sharp declines.
Looking ahead, DRAM's staying power will depend on memory price trends, AI infrastructure budgets, and earnings reports from Micron, Samsung, and SK Hynix. The fund has quickly become a bellwether for the memory chip segment, but its early hype may not guarantee long-term performance.
