The VanEck Semiconductor ETF (SMH) has fallen roughly 17% from its 52-week high of $671.83, yet investors continue pouring billions into semiconductor funds as the AI infrastructure boom drives sustained demand for chip makers. US semiconductor ETFs attracted over $46 billion in inflows during 2026, shattering every previous annual record and roughly doubling the cumulative inflows the sector saw across all years since 2017, according to Crypto Briefing.
Despite the pullback from peaks, SMH remains one of the largest and most active semiconductor vehicles. The fund holds approximately $67.42 billion in total net assets as of July 17, 2026, and has been absorbing massive capital flows even as valuations compressed. On a single day in mid-June 2026, SMH alone pulled in $6.9 billion in net inflows, nearly breaking the $7 billion mark for a single-day ETF flow event, according to ETF.com.
The scale of inflows into semiconductor ETFs reflects the structural shift in capital allocation toward AI infrastructure. Tech giants including Microsoft and Amazon have publicly telegraphed AI infrastructure spending forecasts ranging between $600 billion and $720 billion, according to Crypto Briefing. A disproportionate share of that capital flows directly to semiconductor companies that design and manufacture the GPUs, TPUs, and custom accelerators powering AI workloads.
Record-Breaking Momentum Despite Volatility
The pace of inflows has accelerated dramatically through mid-2026. By the end of June alone, net inflows into US semiconductor ETFs had already hit approximately $39 billion, meaning the back half of the year only needed to maintain a modest pace to cross the $46 billion mark, according to Crypto Briefing. A single day in early July 2026 saw $7.1 billion flood into semiconductor ETFs—more than many asset classes attract in an entire quarter.
The two heavyweights absorbing the bulk of capital are SMH and the iShares Semiconductor ETF (SOXX). In April 2026, those two funds alone pulled in a combined $5.5 billion in a single month, setting a new monthly record for the category. Retail investors have been a meaningful part of the wave, contributing around $3.2 billion in net purchases of semiconductor ETFs since January 2025, signaling this isn’t purely an institutional trade, according to Crypto Briefing.
Total sector assets have swelled to around $165 billion, roughly four times what they were at the start of 2026. The disconnect between price weakness and inflow strength reflects a broader market dynamic: investors view the pullback as a buying opportunity within a secular uptrend driven by AI adoption. When the 2022 semiconductor drawdown occurred, SOXX fell more than 35% peak to trough, according to Crypto Briefing, but the sector recovered. The current correction, while notable, remains modest by historical comparison.
