Retail investors have never put this much money into semiconductor ETFs this fast. In a single month tracked through mid-to-late June 2026, retail buying in US semiconductor ETFs hit approximately $12 billion, a record high that represents a 1,200% increase in buying activity since April.
## The funds getting all the attention
The usual suspects are leading the charge. The VanEck Semiconductor ETF (SMH), one of the largest in the space with assets under management in the $60B to $72B range, counts Nvidia as one of its largest individual holdings, representing roughly 14% to 17% of the portfolio. The iShares Semiconductor ETF (SOXX) is up approximately 90% year-to-date, a number that tends to attract attention from investors who missed the earlier move and are now trying to get in.
Then there’s the newer entrant that arguably stole the show: the Roundhill Memory ETF, ticker DRAM, launched on April 2, 2026. Within five weeks of trading, DRAM had accumulated over $6 billion in assets under management. It has since climbed to nearly $17 billion, which, by any measure, is the fastest asset accumulation in ETF history.
The broader ETF market is also humming. Total US ETF inflows reached $167 billion in April 2026 and $199 billion in May 2026, with technology and semiconductors driving a significant share of those figures.
