AI Infrastructure vs. Electrification ETFs by the Numbers: Assets, Fees and Holdings

By Adam Patti, Chief Executive Officer, VistaShares | Published November 13, 2026

AI infrastructure ETFs and electrification ETFs both follow the physical build-out behind artificial intelligence. One holds the chips, power, cooling and data center hardware AI runs on; the other holds the companies that build and supply the electricity grid. The two themes have the same number of funds and similar overlap with the S&P 500, but one holds about eleven times the assets of the other. This page compares them with dated figures.

What do these two themes hold?

ETFIQ describes AI infrastructure ETFs as funds that hold what the AI boom runs on rather than the companies using it: the chips, the power, the cooling and the data center hardware. It describes electrification ETFs as funds that hold the companies that build and supply the electricity grid: transformers, cables, switchgear and the copper it all needs.

The themes meet at power. Data centers need large amounts of electricity, and the grid has to be expanded to deliver it. An AI infrastructure fund may hold some power equipment makers alongside chip and server companies; an electrification fund may hold many of the same equipment makers, with no chip companies at all. Our articles on grid transformers as an AI bottleneck, hyperscaler capital spending and AI infrastructure vs. AI software ETFs cover the links.

How many funds are there, and how large?

ETFIQ tracked 12 funds in each theme as of November 12, 2026. The similarity ends there. Electrification ETFs held a combined $13.2 billion, and AI infrastructure ETFs held $1.2 billion.

Concentration is high in both. The largest electrification fund held $10.9 billion, about four-fifths of the theme’s assets. The largest AI infrastructure fund held $789 million, about two-thirds of its theme. Most of the other funds in both groups are small, which matters for trading costs and for the chance that a fund closes. Our article on what happens when an ETF closes explains the process.

How do fees compare?

Fees were close. AI infrastructure ETFs ran from 0.37% to 1.00% and electrification ETFs from 0.35% to 0.96%, as of November 11 to 12, 2026. A range shows how much choice exists; the prospectus shows the fee for a specific fund.

How much do these funds overlap with the S&P 500?

About half of the typical fund’s weight sits in S&P 500 stocks in both themes: 49% for electrification, the 9th highest of 54 themes with holdings on file, and 48% for AI infrastructure, the 10th highest. Large U.S. chipmakers, utilities and electrical equipment makers are index members, so an investor who owns an S&P 500 fund already holds part of what these funds own. Our guide to ETF portfolio overlap explains how to check.

How many companies do they hold?

Across their ten largest holdings, the 12 electrification ETFs named 88 different companies, and the 9 AI infrastructure ETFs that ETFIQ can read named 69. The electrification theme draws on a defined supply chain of grid equipment, cable and engineering firms, so many names recur. AI infrastructure funds mix several layers of the stack, from chips to cooling to power, and differ more in what they emphasize.

Where has money been flowing?

In the month to November 11, 2026, electrification ETFs had a net outflow of $73 million across the 5 of 12 funds with daily data, including $131 million out in the final week. AI infrastructure ETFs took in $6 million, but that figure covers just 1 of 12 funds, so it says little about the theme as a whole. The full ranking is on ETFIQ’s theme flows page.

How should investors use these numbers?

Check the layer: AI infrastructure funds can hold chips, servers, cooling or power. Read the holdings to see which layer a fund emphasizes.

Watch concentration: in both themes one fund holds most of the assets, and a few companies can dominate each portfolio.

Frequently asked questions

How many AI infrastructure ETFs are there?

ETFIQ tracked 12 U.S. listed AI infrastructure ETFs on November 12, 2026, holding a combined $1.2 billion.

How many electrification ETFs are there?

ETFIQ tracked 12 U.S. listed electrification ETFs on November 12, 2026, holding a combined $13.2 billion.

What is the difference between the two themes?

AI infrastructure funds hold the chips, power, cooling and data center hardware AI runs on. Electrification funds hold the companies that build and supply the electricity grid.

Do the two themes hold the same companies?

Some power and electrical equipment makers can appear in both. Chipmakers are part of ETFIQ’s definition of AI infrastructure but not of electrification.

Why is the AI infrastructure flow figure so small?

Only 1 of the 12 AI infrastructure funds had daily share data for the period, so the estimate covers a single fund.

Which has more overlap with the S&P 500?

They are nearly the same: 49% for the typical electrification fund and 48% for the typical AI infrastructure fund, as of November 12, 2026.
