WQTM tracks an index that provides exposure to companies worldwide that are involved in quantum computing activities and their development. The index includes companies with the following business activities: quantum chips and qubit technology, quantum software and algorithms, quantum annealing and simulation, quantum-as-a-service, such as cloud-based platforms that provide users with a variety of quantum computing resources, post-quantum cryptography, which may involve cybersecurity, quantum networking and communications, advanced computing, and related tools, materials, and infrastructure…
Is WQTM's expense ratio expensive, average, or a steal for its category?
Pro reveals the verdict on a 5-tier spectrum calibrated against ICI 2025 industry averages, with strategy-aware bands so the comparison is meaningful.

I'm issuing a buy on WisdomTree's WQTM. I've rated Defiance's QTUM a hold since it debuted, based on how it's built, not on quantum's direction. Since WQTM's inception, QTUM returned 32.16% and XLK 25.46% against WQTM's 6.47%. That gap came from megacap tech, not from quantum computing firms. WQTM's index scores each firm on quantum revenue purity. IonQ, D-Wave, and Rigetti are its top three weights. QTUM is equal-weighted, so megacap tech dominates its returns.

The WisdomTree Quantum Computing Fund ETF, which only got listed in October 2025, is up by less than 9% but has seen a far bigger explosion in its AUM, highlighting the interest in this theme. Quantum computing's allure is advancing, aided by hybrid computing setups, lower error rates, and increasing government support, but meaningful commercialization is still a few years off. WQTM's meticulous portfolio construction favors pure-play quantum computing firms, many of which are early-stage and not expected to be profitable before FY29.

ARTY, WQTM, and ARKX represent a progression from commercial AI to speculative quantum computing and diversified space/defense innovation. ARTY is my highest-conviction Buy, backed by strong earnings, hyperscaler capex, and leading AI hardware/software exposure despite a 37x earnings multiple. WQTM is a speculative buy, offering quantum computing optionality but trading at 119x trailing earnings; position sizing should be small due to high valuation risk.

Quantum ETFs are gaining momentum as U.S. funding and breakthroughs accelerate the sector, offering investors diversified exposure to its growth.

Technology stocks, and nearly every other segment with ties to the artificial intelligence (AI) trade, are in the midst of a two-month swoon as market participants look for greener, non-tech pastures. Not surprisingly, quantum computing equities are getting the bad end of that deal.
