The Micron-led Roundhill Memory ETF (DRAM) just reached $6.5 billion in assets in 36 days, making it the fastest ETF to hit that mark and beating the early 2024 bitcoin ETF boom, according to Bloomberg Intelligence ETF analyst Eric Balchunas.
BlackRock’s iShares Bitcoin Trust ETF (IBIT) took 43 days to reach $6.5 billion, while Fidelity’s Wise Origin Bitcoin Fund (FBTC) took 51 days
That makes the AI memory trade one of the hottest ETF stories on Wall Street in the post-pandemic era — and a major acceleration from last week’s surge, when DRAM was barely a month old. The fund’s latest jump in assets came as DRAM soared 13% Friday and pulled in another $1 billion in inflows, according to Balchunas. In early trading Monday, DRAM opened up over 3% before retreating as its largest holding, Micron (MU), opened with a gain over 5%.
Micron makes up 27% of DRAM — barely edging out SK Hynix (000660.KS) at 26% and Samsung Electronics (005930.KS) at 20%, according to the fund’s latest holdings. Sandisk (SNDK), Kioxia (285A.T), Seagate Technology (STX), and Western Digital (WDC) round out the next tier. That’s also where the bull case gets interesting.
