DRAM — Roundhill Memory ETF
Semiconductors / AI chips · The picks-and-shovels of the AI build-out.
The first pure memory-chip ETF — DRAM, NAND and the HBM stacks that feed AI training. It rocketed past $20B in weeks (the fastest-growing launch on record), which tells you how crowded the memory trade has become. One clean ticker for the SK Hynix / Samsung / Micron supercycle — but three names are ~70% of it, it runs on total-return swaps, and memory is a brutally cyclical, boom-and-bust business. A theme bet, not a diversified core. Semiconductors are the picks-and-shovels of the AI build-out: an infrastructure-level AI bet rather than a pure software one.
