The Commerce Department’s $2 billion in planned CHIPS R&D funding for nine quantum companies, announced in May, gave the quantum computing trade something it lacked for a decade: a federal balance sheet behind it. Three exchange-traded funds capture the trade from different angles. The Defiance Quantum ETF (NASDAQ:QTUM) is the closest thing to a pure-play. The Invesco PHLX Semiconductor ETF (NASDAQ:SOXQ) owns the chip layer underneath every qubit. The Global X Artificial Intelligence & Technology ETF (NASDAQ:AIQ) is the broader bet on the hyperscalers funding the whole stack.
The funds have responded very differently to the same news cycle, with SOXQ up about 86% year-to-date, QTUM up around 43%, and AIQ up roughly 24%. The gap between them says more about how investors are pricing the theme than any prospectus can.
What Actually Changed in May
The Department of Commerce signed letters of intent with nine companies under the CHIPS Research and Development program. IBM is in line for $1 billion to build a quantum foundry subsidiary focused on superconducting wafers, and GlobalFoundries is set to receive $375 million for a domestic foundry spanning superconducting, trapped ion, photonic, topological, and silicon spin architectures. Seven smaller awards, including $100 million for Atom Computing and $38 million for Diraq, target specific engineering problems: cryogenic systems, control hardware, ultra-fast readout electronics, and photonic loss.
That last list matters for ETF selection, as federal funds are flowing primarily to foundry capacity and private companies tackling fabrication bottlenecks, rather than to public pure-play names that retail investors associate with quantum. Funds that own the chip supply chain catch more of that spending than funds that own quantum brand names.
QTUM: The Pure-Play Vehicle
Defiance Quantum tracks the BlueStar Quantum Computing and Machine Learning Index and is the fund most investors reach for when they want the theme on a single ticker. It holds 85 positions spanning quantum hardware specialists, machine learning software, and the larger semiconductor names whose research budgets fund the field. That structure is the point, as pure quantum names like IonQ, D-Wave, and Rigetti are too small and too speculative to anchor a fund on their own, so QTUM blends them with the IBMs, Googles, and Honeywells doing the heavy R&D.
The fund carries a 0.40% expense ratio and roughly $6 billion in assets, which makes it the largest dedicated quantum vehicle on the market. Its 73% one-year return trails SOXQ but sits well above broad tech benchmarks. A note of caution from outside the fund: industry voices interviewed on The AI Investor Podcast have argued that commercial quantum is probably at least five years away and could be longer, and that the eventual winners may be IBM, Microsoft, and Google rather than the small pure-plays. QTUM owns both camps, which is a feature for investors who do not want to pick.
The trade-off: a beta of about 1.35 and a P/E near 37 mean drawdowns will be sharper than those of a diversified tech fund. The 7% slide over the past week is a preview of how quickly sentiment can turn against a name like this.
SOXQ: The Foundry Trade
Invesco’s PHLX Semiconductor ETF is the strongest fit for investors who read the Commerce announcement and concluded that the money goes to fabs first. It tracks the PHLX Semiconductor Sector Index, holds 32 chipmakers, and charges 0.19%, the lowest fee among the three funds and one of the lowest in the entire semiconductor category.
The mechanism connecting SOXQ to the quantum push is direct. Superconducting qubit systems require cryogenic control chips, low-noise amplifiers, and custom analog electronics. The Commerce program is explicitly targeting cryogenic systems integration, control hardware, and ultra-fast readout electronics, all of which are handled by companies in this index. IBM and GlobalFoundries, the two foundry recipients, operate within the semiconductor industry; their planned spending translates into orders for the equipment makers and design houses that SOXQ owns.
The fund’s 86% year-to-date gain and 139% one-year return reflect that the market has already absorbed part of this thesis. A P/E near 56 leaves little margin for a miss in AI capex, which is the primary driver of the semiconductor cycle. Quantum funding is additive to the case here, layered atop the broader AI capex cycle that drives the semiconductor thesis.
AIQ: The Hyperscaler Wrapper
Global X’s AI & Technology ETF is the contrarian inclusion on this list. Its top holdings are Alphabet at 4.5%, Broadcom and Samsung at 3.8% each, AMD at 3.7%, and Apple and Tesla at 3.5%, which looks like a generic mega-cap technology fund at first glance. The quantum link runs through the cloud layer. Alphabet, IBM, and Microsoft are the three companies most likely to commercialize quantum first, and they will do so by renting access to qubits, much like they rent GPU time today.
AIQ also brings meaningful foreign exposure. Samsung Electronics, Taiwan Semiconductor, Alibaba, and Tencent together account for a non-trivial share of the fund, and the sovereign quantum programs in Asia are running on parallel tracks to the U.S. effort. The fund holds $10.5 billion in assets at a 0.68% expense ratio. The lagging 24% year-to-date return tells you the market is not yet treating AIQ as a quantum vehicle, which is precisely why it could be one for investors who think the trade is early.
Choosing Between Them
Each fund answers a different question. QTUM is for the investor who wants the cleanest read on quantum sentiment and is willing to tolerate the volatility that comes with names whose revenue may not arrive for years. SOXQ fits the investor who believes the federal money will be spent on equipment and wafers before it is spent on qubits, and who is comfortable buying a sector that has already run hard. AIQ is the slowest, broadest expression of the theme: a way to own the companies that will host quantum services without owning the unprofitable specialists.
One fund the list deliberately omits is the single-stock quantum names packaged into leveraged ETFs that emerged in late 2025. The Commerce program’s emphasis on foundry capacity and engineering subproblems argues for diversified exposure rather than concentrated bets on whichever pure-play wins in a specific qubit modality.
