Roundhill Memory ETF doubles in 2026, driven by AI demand for memory chips and strong earnings from top holdings.

The Roundhill Memory ETF (DRAM) has surged about 107% in 2026, doubling since its April launch, fueled by strong demand for AI-related memory products like high-bandwidth memory and NAND flash. Key holdings such as Micron, SanDisk, Samsung, and SK Hynix have reported record revenues and robust forward guidance, reflecting a structural growth trend driven by hyperscaler cloud demand. However, the ETF's concentrated exposure to the cyclical memory sector poses risks of volatility and profit-taking, with some market sentiment already cooling. Investors should watch if the ETF maintains its gains above $55 and how upcoming earnings reports support the AI memory supercycle thesis.
