The Roundhill Memory ETF (NYSEMKT: DRAM) has become one of the most closely watched thematic funds in the market, driven by explosive demand for high-bandwidth memory chips.
The ETF launched on April 2 and gathered nearly $10 billion in net assets in under 45 days, a record pace for ETF asset growth in recent history.
Shares climbed from around $26 at launch to more than $81 at their peak, representing a roughly 78% gain in under two months before pulling back to the $70s by late June.
That kind of rapid price appreciation is exactly the scenario that typically prompts fund managers to consider a share split, bringing the price back to a more accessible range for retail investors.
Roundhill has executed splits on other thematic funds before, and given the DRAM ETF’s trajectory, a split later this year appears to be a realistic and likely outcome.
The fund holds a highly concentrated portfolio, with SK Hynix and Samsung Electronics each accounting for roughly 24.5% of assets, Micron Technology at around 26%, and Sandisk rounding out at 4.8%.
That means nearly 80% of the entire fund is concentrated in just four companies, making it a direct and deliberate bet on the global memory supply chain rather than a diversified tech play.
The underlying holdings have delivered extraordinary returns, with SK Hynix stock climbing roughly 300% this year and Samsung up around 195%, fueled entirely by AI-driven HBM demand.
Every time a hyperscaler deploys another cluster of AI servers, memory companies capture a portion of that infrastructure order, and that pipeline shows no signs of slowing.
The structural case for memory goes deeper than a single demand cycle, as newer AI architectures are stacking more HBM on each accelerator than the previous generation, meaning memory requirements per chip are growing over time.
That long-term architectural shift gives the fund a tailwind beyond just near-term supply constraints, which have driven prices sharply higher across the sector.
Investors should be aware that memory is a cyclical industry, and the same high prices currently boosting margins will eventually attract additional supply, which could compress earnings later in the cycle.
Concentration risk is also a real consideration, since any significant setback at Micron, Samsung, or SK Hynix would be felt immediately and heavily across the entire portfolio.
For U.S. retail investors who want exposure to Korean memory giants that are otherwise difficult to access directly, the DRAM ETF offers a straightforward and liquid way to participate in the AI infrastructure buildout.
With a record asset base, a price that has nearly tripled since April, and structural AI memory demand continuing to grow, the Roundhill Memory ETF looks like a strong candidate for a stock split before the year is out.
