Roundhill Memory ETF saw $553.7 million in new inflows on May 29, ETF.com reported Monday, keeping the AI-memory fund in the list of top 10 daily creations among U.S. ETFs. Assets hit $13.36 billion. The fund is an exchange-traded basket of securities that trades like a stock.
ETF flows have shifted, with the trade picking up large-scale funds. U.S.-listed ETFs pulled in roughly $200 billion in May. DRAM picked up close to $8 billion, jumped over 60% in the month, and finished May around $13.4 billion in assets, ETF.com said.
New from Roundhill, the fund targets high-bandwidth memory (HBM), DRAM, and NAND. HBM is stacked memory paired with AI chips. The fund, DRAM, started trading April 2 and aims for direct exposure to global memory chip stocks. It carries a 0.65% gross expense ratio, according to .
Roundhill’s fact sheet lists Samsung Electronics at 24.99%, SK hynix at 24.22% and Micron Technology at 23.83% as the top holdings at launch. It also holds smaller stakes in Kioxia, SanDisk, Western Digital and Seagate. The portfolio showed a 49.25% weight for South Korea and 37.65% for the United States. These numbers include both stocks and total return swaps, with the swaps giving exposure without direct ownership.
“A lot of investors view this as a proxy for alluring but otherwise hard-to-access Korean stocks,” Steve Sosnick, market strategist at Interactive Brokers, told Reuters earlier in May. Dave Nadig at ETF Trends said investors were “jumping in with both feet” after DRAM hit $1 billion in assets in just 10 trading days. Reuters
DRAM saw $608.4 million in inflows on May 28, landing just behind big names like Vanguard’s S&P 500 ETF and Invesco QQQ, according to the last two flow reports. VanEck Semiconductor ETF, or SMH, had a $1.0 billion redemption in the same table.
Chip ETF options are still out there. The iShares Semiconductor ETF (SOXX) gives broader U.S.-listed chip sector coverage, while SMH holds both designers and names like ASML, Lam Research and Applied Materials on the supply side. DRAM stays focused on memory pricing, though it’s not as spread out.
Chip sector names moved in different directions late Tuesday morning. DRAM held near $68.09 as of 10:57 a.m. EDT. SMH and SOXX traded up, but Micron and SanDisk dipped, according to finance data.
But the structure has risks. Roundhill says memory stocks are open to swings in prices, supply trouble, technical glitches and export curbs, while swaps add leverage, counterparty and pricing risk. DRAM’s tight bet could see bigger losses if HBM supply gets ahead of forecasts or AI data-center demand drops.
Chris Gannatti, global head of research at WisdomTree, called the wider trend a hardware rally. “We are seeing a broadly favorable tech hardware environment,” he said. For DRAM investors, the main question now is not if AI will keep attracting money, but if memory stays the key bottleneck long enough to support the fund’s new scale. thedailyupside.com
