Tech stocks just recorded their largest five-week inflow in history, according to market data provider Barchart, as tech ETFs captured roughly 69% of all sector inflows in the first half of 2026. The Roundhill Memory ETF and the Invesco Nasdaq 100 ETF drew $12.73 billion and $12.39 billion, respectively. The closest parallel is 2021's $163 billion inflow wave, though this rotation is narrower and concentrated specifically on tech and AI themes.
Technology stocks just posted their largest five-week inflow in history, according to market data provider Barchart. Investors funneled money into tech ETFs at a pace that captured roughly 69% of all sector inflows during the first half of 2026, as artificial intelligence and semiconductor plays absorbed the bulk of the capital.
Two funds power the Nasdaq-100 and memory-chip rotation
Two funds led the shift: one tracking the Nasdaq 100 index, the other the memory chip market. The Roundhill Memory ETF, ticker DRAM, pulled in $12.73 billion since its April 2026 launch.
Meanwhile, the Invesco Nasdaq 100 ETF, ticker QQQM, attracted $12.39 billion over the same window. Broader ETF inflows across all categories surpassed $100 billion by mid-year, with U.S. tech and AI supply chain products accounting for a disproportionate share of that total.
How the rotation compares with 2021
The closest historical parallel came in 2021, when equity mutual funds and ETFs recorded $163 billion in inflows over a five-week stretch, a period marked by post-pandemic optimism and near-zero interest rates fueling risk appetite across the board. Yet the 2026 version is narrower and more deliberate, concentrated specifically in technology and AI-adjacent themes rather than spreading across the risk spectrum.
Crypto stays on the sidelines
No cryptocurrencies or digital assets appeared in any of the reporting around this historic tech inflow. That absence doesn't mean crypto is fading, but it does suggest where risk-seeking capital is choosing to go when given a compelling alternative narrative.
The AI trade offers something crypto often struggles to provide: a legible, corporate earnings-backed story, as Nvidia reports revenue, semiconductor foundries report capacity utilization, and memory chip producers report demand from hyperscalers.
For equity investors already in the trade, the 69% sector share that tech ETFs command is a reminder that crowded trades eventually get less crowded. What remains to be seen is whether earnings from semiconductor and AI infrastructure companies keep justifying the pace of inflows.
