In a stunning display of investor enthusiasm for artificial intelligence, the Roundhill Memory ETF (DRAM) has achieved a historic milestone, amassing $10 billion in assets in just 50 trading days since its launch on April 2, 2026. This makes it the fastest exchange-traded fund to reach that mark, surpassing previous records held by the iShares A.I. Innovation and Tech Active ETF (BAI), which took 556 days, and the Fidelity Wise Origin Bitcoin Fund, which crossed $10 billion in 81 days in 2024.
AI-Driven Demand Fuels Memory Chip Rally
The fund, which targets companies involved in memory chip production, has surged 87% since its debut, driven by an unprecedented boom in AI data center construction. Memory chips, particularly high-bandwidth memory (HBM), are critical for handling the massive data loads required by AI models. The ETF's top holdings—Micron Technology (MU), SK Hynix, and Samsung Electronics—have seen their market values soar, with Micron and SK Hynix briefly crossing the $1 trillion mark this week. Samsung also hit a record high.
According to Goldman Sachs Global Institute, cumulative AI infrastructure spending is projected to reach approximately $7.6 trillion from 2026 to 2031, with memory demand already factored into silicon spending projections. This has shifted investor focus from AI leaders like Nvidia to the hardware that powers model training and deployment.
Record Inflows and Market Impact
DRAM has attracted $8.6 billion in inflows, according to Morningstar data cited by the Financial Times. The fund's active management strategy, with a 0.65% expense ratio, focuses on companies in HBM, dynamic random-access memory (DRAM), NAND flash, and solid-state storage. At launch, Samsung Electronics comprised 24.99% of the portfolio, SK Hynix 24.22%, and Micron 23.83%, with smaller allocations to Kioxia, SanDisk, Western Digital, Seagate, Nanya Technology, and Winbond.
“Memory is moving to the center of the AI ecosystem,” said Roundhill CEO Dave Mazza at the time of launch. The ETF trades on the Cboe BZX exchange and uses total return swaps to maintain exposure while meeting diversification rules.
Leveraged Version Filed
Wall Street is racing to capitalize on the trend. Themes ETF Trust has filed with the U.S. Securities and Exchange Commission for the Leverage Shares 2X Long Memory Daily ETF, which would target 200% of DRAM's daily returns for short-term trading. This move highlights the rapid packaging of the memory theme into new products.
Analyst Optimism and Risks
Analysts remain bullish on memory stocks. UBS raised its price target on Micron to $1,625 from $535, the highest among 46 brokerages tracked by LSEG, citing AI's transformation of the memory market. Art Hogan, chief market strategist at B. Riley Wealth, called Micron's $1 trillion milestone “an exclamation point” on AI data center demand. In South Korea, SK Hynix ended Wednesday up 9.3%, with a market cap of $1.12 trillion. Kim Young-gun, an analyst at Mirae Asset, noted that demand for memory chips should outpace supply through 2028, keeping prices strong.
However, risks remain. The fund is heavily concentrated, with nearly three-quarters of assets in just three stocks. Daniel Sotiroff, associate director for ETF passive strategies research at Morningstar, warned that the surge in buying resembles the COVID-era rush into thematic ETFs, where many investors piled in near the top. If memory capacity ramps up faster than expected, the same momentum that drove inflows could reverse, especially with leveraged products adding short-term trading pressure.
Fundstrat's Hardika Singh noted that memory and storage ETFs are “launching in troves” as issuers race to join the rally, flagging Micron, SanDisk, Seagate, and Western Digital as some of this year's strongest stocks.
