Investors looking for the next leg of the artificial intelligence trade are increasingly turning to memory-focused ETFs, as a rally in memory-chip stocks and the prospect of a U.S. listing by SK Hynix drive fresh interest in the sector.

The Roundhill Memory ETF (BATS:DRAM), which is the only pure-play memory-focused fund, gained nearly 5% early Monday morning trading, extending a remarkable run that has seen the fund surge about 190% since its April launch. The advance comes ahead of Micron Technology Inc’s (NASDAQ:MU) earnings report this week and amid reports that SK Hynix, one of the ETF’s largest holdings and Nvidia Corp’s (NASDAQ:NVDA) leading supplier of high-bandwidth memory chips, could debut on the Nasdaq as early as August.

Then tighten the rest of the story around ETFs:

AI Investors Are Making A More Concentrated Bet

Rather than owning broad semiconductor funds, investors are increasingly using memory ETFs to target what many see as the next phase of the AI buildout.

DRAM’s largest holdings include SK Hynix, Samsung Electronics, and Micron, companies at the center of a memory market benefiting from surging demand for AI servers. The ETF has emerged as a focused way to gain exposure to high-bandwidth memory, a critical component used in advanced AI systems.

The fund’s performance has mirrored the strength of its holdings. SK Hynix has surged roughly 350% this year (as on the Korea Exchange), recently overtaking Samsung Electronics as South Korea’s most valuable company. In the U.S., memory stocks have also rallied sharply, with Western Digital Corp (NASDAQ:WDC), Seagate Technology Holdings PLC (NASDAQ:STX), SanDisk Corp (NASDAQ:SNDK), and Micron posting fresh gains as investors bet that AI-driven demand will keep memory pricing elevated.

SK Hynix IPO Adds Another ETF Catalyst

The prospect of a Nasdaq listing for SK Hynix could provide another tailwind for memory-focused ETFs.

The South Korean chipmaker reportedly filed confidentially with the Securities and Exchange Commission in March and has lined up Citigroup, JPMorgan, Goldman Sachs, and Bank of America to manage the offering. If completed, the listing would rank among the largest U.S. IPOs in recent years and give American investors direct access to one of the most important suppliers in the AI supply chain.

For DRAM investors, the potential listing reinforces the growing importance of memory manufacturers in an AI market that has historically been dominated by GPU makers such as Nvidia.

Micron Earnings Put Memory ETFs In Focus

The next major catalyst for the sector arrives Wednesday when Micron reports fiscal third-quarter earnings.

Analysts broadly expect another strong quarter driven by AI-related demand, and the stock has received several price-target increases in recent weeks. Because Micron is among the ETF’s largest holdings, the results could influence sentiment across the entire memory ETF category.

Investors will be watching not only for earnings growth but also for management’s outlook on HBM demand, memory pricing, and AI-related spending trends. A strong report could reinforce the view that memory remains one of the most attractive ways to gain exposure to AI infrastructure through ETFs.

While diversified products such as VanEck Semiconductor ETF (NASDAQ:SMH) and iShares Semiconductor ETF (NASDAQ:SOXX) spread exposure across chip designers, manufacturers, and equipment makers, DRAM offers a concentrated bet on memory suppliers and storage companies.

And for now, memory ETFs remain one of the market’s most concentrated and successful ways to bet on the continued expansion of artificial intelligence.
