Memory ETF Soars with $1 Billion in Assets in Just 10 Days

The Roundhill Memory ETF, trading under the ticker DRAM, has amassed $1 billion in assets within about 10 days of its April 2, 2026 launch.

The fund's portfolio is heavily concentrated in three companies: Micron Technology (25.96%), Samsung Electronics (25.40%), and SK Hynix (23.46%). Together, these memory chip giants account for nearly three-quarters of the fund's exposure.

The remaining quarter is spread across other memory semiconductor names and related companies, with the ETF using a mix of equities and derivatives to build its positions.

The speed of DRAM's asset accumulation has drawn comparisons to the spot Bitcoin ETFs that reshaped crypto markets when they debuted.
