Dram Memory ETF: The newly launched DRAM is rapidly emerging as one of the hottest artificial intelligence-related investment products on Wall Street.

The exchange-traded fund, introduced by Roundhill Investments on April 2, focuses on the booming memory chip sector tied to growing AI demand.


The fund has attracted more than $5 billion in investor inflows since its debut.


More than $1.1 billion flowed into the ETF on Thursday alone, highlighting strong market enthusiasm for AI-linked semiconductor investments.


The ETF posted an exceptionally fast start after launch. It surpassed $1 billion in assets within its first 10 trading days.


According to Goldman Sachs, that pace places the fund among the fastest-growing ETF launches in recent years.


Only a handful of major ETF debuts reached the milestone more quickly.


Those include the launch of spot bitcoin ETFs three years ago, the widely followed LQD corporate bond fund from iShares, the GLD gold ETF from SPDR, and JPMorgan’s BBCA Canadian equity fund.


The rapid rise of the DRAM ETF reflects continued investor demand for companies benefiting from the artificial intelligence boom, particularly firms tied to high-performance memory technology used in AI infrastructure and data centers.


Roundhill Investments CEO Dave Mazza said memory chips have become one of the most critical constraints in the artificial intelligence industry.


Speaking by phone, Mazza said demand for advanced memory technology continues to outpace available supply.


He added that the shortage is expected to persist for years rather than only a single quarter.


The strong demand has fueled rapid growth for the DRAM since its launch earlier this year.


The ETF has recorded investor inflows during every trading session since debuting, extending its streak to 23 consecutive sessions. At the same time, the fund has surged roughly 70% in value.


Several of its leading holdings, including Micron Technology and SanDisk Corporation, have continued posting record gains as investors increase exposure to AI-related semiconductor companies.


Options traders are increasingly turning to the DRAM as investors seek new ways to capitalize on the artificial intelligence boom.


Trading activity in the ETF’s options market surged on Thursday, with more than 90,000 contracts changing hands.


Bullish sentiment dominated trading activity, as call options significantly outpaced put options by nearly two-to-one.


The strong demand has quickly pushed the fund into the top 40 U.S.-listed ETFs ranked by options trading volume.


Investor interest has also been supported by the ETF’s exposure to major Asian semiconductor companies tied to the AI supply chain.


Its holdings include leading South Korean chipmakers SK Hynix and Samsung Electronics, both of which are viewed as key suppliers in the global memory chip market.


Dave Mazza said the popularity of the DRAM is partly driven by investor demand for direct exposure to major global memory chip manufacturers.


Mazza noted that some of the world’s largest memory companies remain difficult for many U.S. investors to access through traditional investment products.


He said investors purchasing broad South Korean equity funds often gain exposure to industries unrelated to semiconductors.


He also pointed out that diversified semiconductor ETFs may allocate only limited weightings to memory-focused companies such as Micron Technology.

According to Mazza, the DRAM ETF was designed to provide more concentrated exposure to the memory chip sector, which has become increasingly important in the expansion of artificial intelligence infrastructure.
