The cheapest AI infrastructure ETFs
A fee is one fact and not a verdict on the fund. Where the funds on a theme hold different companies, the cheapest is not even the same bet, and the holdings are on the theme page.

Method
The 10 of 11 ETFs in the ai infrastructure and chips theme that publish an expense ratio, cheapest first. Across the funds listed here the annual fee runs from 0.5% to 0.8%. A fee is the one number a fund controls and the one a holder pays whatever happens. The ranking is the published field sorted, nothing else: no scoring, no weighting and no view on any fund. Every fund ETFIQ covers in this category is eligible, including funds that have closed, because leaving them out would flatter the category.
ETFIQ links to the documents behind every figure. It is not affiliated with any issuer, and a link is not an endorsement. A ranking is not a recommendation and no order on this site is an opinion. ETFIQ is an independent publisher, not an adviser.
