What happened

Roundhill Investments — with T-REX (the REX Shares × Tuttle Capital joint venture) — launched the Roundhill T-REX 2X Long DRAM Daily Target ETF ($RAM) on June 24, 2026. RAM "seeks daily investment results… that correspond to two times (2X) the daily performance of the Roundhill Memory ETF (DRAM)" — i.e. a leveraged wrapper on the memory basket.

The underlying $DRAM (the first-ever memory-stock ETF, launched April 2, 2026; holdings Micron, Samsung, SK Hynix, SanDisk) is per the issuer "the most successful ETF launch in history — surpassing $20B AUM in just over two months of trading with a total return of 179.84%." RAM debuted with the largest day-one trading volume of any US-listed leveraged or inverse ETF (BusinessWire), targeting "active traders who want to express high-conviction views on the memory cycle."

Why it matters

• memory-supercycle: the arrival of a 2x leveraged wrapper — and DRAM itself being the fastest ETF ever to $20B — is a structural intensity readout on the memory trade. Alongside the same-day SK Hynix $29.4B ADR filing (cited), it marks the memory cycle graduating from thesis to a full retail product wave. This is the froth/plumbing layer, not new fundamental evidence; a 2x-ETF launch at a record is as much a lateness tell as a confirmation.
• Ticker-identity note: RAM is a decay-prone 2x daily ETF — event tag only, not a trend-hold instrument. $DRAM (unlevered basket) is the tradeable memory-theme vehicle we already track (MU / SNDK are the single-name picks).
