The best AI infrastructure ETFs let you invest in the entire artificial intelligence buildout through a single ticker. Instead of picking individual winners among GPU makers, data centre operators, and networking companies, you gain diversified exposure to every layer of the AI stack with lower risk and simpler portfolio management.
Why AI Infrastructure ETFs Deserve a Place in Your Portfolio
You face a fundamental challenge when investing in AI: the technology moves faster than any single company can dominate. An AI infrastructure ETF solves this by spreading your capital across semiconductors, cloud providers, power systems, and cooling specialists simultaneously. If one holding underperforms, the broader basket absorbs the loss. You also avoid the concentration risk that comes with loading up on the best AI infrastructure stocks individually.
The sector has a structural tailwind. Hyperscaler capital expenditure is projected to exceed $300 billion in 2025 alone, and that spending flows directly into the companies these ETFs hold. Understanding where those dollars go is central to the AI infrastructure spending forecast through 2030.

AIQ: The Broadest AI Infrastructure Play
The Global X AIQ ETF tracks the Indxx Artificial Intelligence and Big Data Index. It holds roughly 85 stocks across the full AI value chain, from chipmakers to cloud platforms to enterprise software. NVIDIA typically represents 8 to 10% of the fund. You get meaningful infrastructure exposure alongside application-layer companies, which balances cyclical hardware risk with recurring software revenue.
ARTY: Hardware-Heavy AI Exposure
The iShares ARTY ETF leans heavily into semiconductors and physical infrastructure. TSMC, Broadcom, and NVIDIA collectively make up over 20% of the portfolio. If you believe the AI buildout remains in its early innings, ARTY gives you concentrated exposure to the companies manufacturing the silicon that every AI workload requires.
How to Choose the Right AI Infrastructure ETF
Your decision comes down to three factors. First, expense ratio: KOMP charges just 0.20% while CHAT charges 0.75%, and that gap compounds over years. Second, concentration: some funds hold 30 stocks while others hold 85, so decide how much diversification you want. Third, overlap with existing holdings. If you already own individual positions in the best AI infrastructure stocks, check for duplication before buying an ETF that holds the same names.
You should also consider pairing an AI infrastructure ETF with data centre REITs for real estate exposure to the physical facilities these companies depend on. REITs provide income through dividends while ETFs capture capital appreciation from the technology itself.
FAQ

Are AI infrastructure ETFs better than buying individual AI stocks?
