For the first time in five years, the Invesco NASDAQ 100 ETF (QQQM) has genuine competition from cheaper funds tracking the identical index — but the bid/ask spread math and tax trap mean the 0.10%-fee newcomers are the right choice for fewer investors than the headline numbers suggest.

State Street launched the SPDR Portfolio Nasdaq 100 ETF (QNDX) on June 24, 2026, at a 0.10% expense ratio. BlackRock followed on July 9, 2026, with the iShares Nasdaq 100 ETF (IQQ), carrying a 0.12% gross expense ratio reduced to 0.10% net through a fee waiver set to expire on July 31, 2027. Both undercut QQQM's 0.15% fee — a gap that sounds decisive until you look at what investors actually pay in total cost, and what a taxable-account switch would cost in a single year.

QQQM's Five-Year Run and What Changed

QQQM launched in October 2020 as Invesco's response to a simple investor complaint: QQQ cost too much and was structured in a way that prevented dividend reinvestment. At 0.15% per year — 77% below the peer-group median for large-growth ETFs, according to Invesco — and built as a modern open-end fund rather than the unit investment trust structure QQQ used until December 2025, QQQM offered the same Nasdaq-100 exposure more efficiently and more cheaply.

The fund's growth has been remarkable. From $72.3 billion in assets as of June 2026, QQQM crossed $100 billion in total assets under management in mid-July, cementing its role as the dominant low-cost Nasdaq-100 vehicle for retail investors and financial advisors. Its 30-day median bid/ask spread stands at 0.01% — a number that will matter shortly.

What QNDX and IQQ Actually Cost

The five-basis-point annual fee advantage of QNDX and IQQ over QQQM is real — but "annual fee" is not the same as "total cost of ownership."

State Street's QNDX entered the market with $24.9 million in total assets as of late July 2026, according to DividendVision. IQQ began trading at $24 per share and attracted modest initial inflows. Neither fund has yet established the scale that forces market makers to compete aggressively on prices. The result: both QNDX and IQQ carry 30-day median bid/ask spreads of approximately 0.04%, compared to QQQM's 0.01%.

That 0.03% spread differential is three basis points per transaction — and it compounds against the newer funds' advantage. A retail investor making a single annual contribution to a Nasdaq-100 ETF pays the spread once going in (buying) and once going out (selling). Over a 30-year holding period, the round-trip spread cost at 0.03% differential represents 0.06% in added friction — while the annual fee advantage of 0.05% accumulates to approximately 1.5% in total over the same period if the spread premium disappears when the fund scales. For investors who make frequent contributions, the math shifts further in QQQM's favor: every transaction incurs the spread, while the fee advantage accrues only once per year.

"The Qs are, outside of SPY, probably the second-most famous, most well-known ticker," Bloomberg Intelligence senior analyst James Seyffart noted following IQQ's debut, implying that brand recognition is itself a liquidity factor — one that will take years for QNDX and IQQ to replicate.

Beyond spread costs, QNDX carries a specific structural risk: a fund with $24.9 million in assets is vanishingly small for an index ETF. Small funds face higher closure risk, wider spreads during volatility events, and limited market-maker depth during periods of stress. The 0.05% annual fee advantage does not compensate for the risk of finding oneself in a fund that announces closure and forces a redemption — which would itself trigger a taxable event.

IQQ carries a different risk: the fee advantage exists only as long as the waiver does. BlackRock's gross expense ratio of 0.12% — which becomes operative on August 1, 2027 if the waiver is not extended — would put IQQ two basis points above QNDX's 0.10% gross fee and only three basis points below QQQM's 0.15%. The net-fee comparison that IQQ's marketing leads with is a temporary condition, not a structural feature.

Two Populations, Two Answers

The right question for a Nasdaq-100 ETF decision in August 2026 is not "which fund charges less?" but "which investor category are you?"

For existing QQQM holders in taxable accounts: The answer is almost certainly to stay. Selling a position with embedded long-term capital gains to capture a five-basis-point annual fee advantage triggers a federal tax liability — at 15% or 20% long-term capital gains rates depending on income — that will almost certainly exceed a decade or more of fee savings in a single year. An investor who bought $100,000 of QQQM at inception in October 2020 and saw it appreciate at the fund's compounded rate would hold a position with substantial embedded gains. Triggering that gain to save $50 per year on a $100,000 position ($150 vs. $100 in annual fees) would require 30 or more years at the lower fee just to break even on the tax cost — not accounting for the opportunity cost of the taxes paid.

For new investors starting fresh: The calculus is genuinely different, but QQQM still has a reasonable case. QNDX's $24.9 million asset base and IQQ's fee-waiver dependency both carry real risks that QQQM's four-year track record, $101 billion in AUM, and daily inflows dwarfing rivals do not. For a tax-advantaged account (IRA, 401(k), HSA) where capital gains taxes are deferred or eliminated, either IQQ or QNDX becomes a reasonable consideration — with QNDX's permanent 0.10% gross fee giving it a structural advantage over IQQ's time-limited waiver if the investor's time horizon is longer than one year.

The early flow data is instructive. Three weeks after IQQ's debut, QQQ was still attracting roughly 300 times more inflows than its new competitor, according to a Benzinga analysis published July 27, 2026. QQQM collected $79 million in inflows on July 24, with multiple sessions exceeding $200 million over the prior month. State Street's QNDX briefly attracted $49 million in a single session on July 23, then flattened to near-zero the following day, according to JPMorgan data cited by Benzinga.

Investors are, in aggregate, making the same calculation this article describes: the fee advantage of the new funds is real, but QQQM's liquidity moat and track record are proving stickier than the five-basis-point difference.

What the Bid/Ask Spread Actually Costs

The spread comparison deserves its own arithmetic because it is the single factor most competing coverage buries in a footnote.

A bid/ask spread of 0.04% means that when an investor buys $10,000 of QNDX or IQQ, they effectively pay approximately $4 in immediate market friction — the difference between what they could sell it for the instant they buy it. QQQM's 0.01% spread costs approximately $1 on the same $10,000 purchase. The difference is $3 per $10,000 invested per transaction.

For an investor making a $10,000 annual contribution to a Nasdaq-100 ETF over 30 years, that $3 spread premium per year (in the buy transaction alone) costs $90 in nominal terms — before considering the compounding of the capital not invested. Against a fee advantage of $5 per year (0.05% × $10,000), the spread consumes 60% of the annual savings from choosing QNDX or IQQ over QQQM.

This analysis assumes spreads stay at current levels. As QNDX and IQQ accumulate assets, their spreads will likely narrow toward QQQM's range. The relevant question for today's investor is: how long will it take, and do you want to be a customer of a $25 million fund while waiting?

QQQM's Concentration Risk Has Not Changed

None of the fee competition changes QQQM's structural risk profile: approximately 60% in technology, with the top ten holdings comprising close to half the portfolio weight. NVIDIA leads at roughly 8.9% of the portfolio as of the fund's most recent disclosure, followed by Apple, Microsoft, Amazon, and other Magnificent Seven components.

That concentration delivered the fund's trailing returns — on a 12-month basis through July 31, 2026, QQQM outpaced large-growth category peers substantially, consistent with the AI infrastructure spending cycle that has powered its largest holdings. It also means drawdown risk is amplified when tech sentiment turns: QQQ declined approximately 32.45% in calendar year 2022 against the S&P 500's 18.21% drop, per Invesco's own factsheet.

Hyperscaler AI capital expenditure — the spending by Microsoft, Amazon, Alphabet, and Meta on data centers and AI infrastructure — is projected at between $630 billion and $770 billion in 2026. That spending sits behind QQQM's revenue lines. Analyst consensus projects 25% to 30% earnings-per-share growth for the Magnificent Seven group in 2026, a figure that, if met, would justify current valuations. If it disappoints, the concentrated nature of the portfolio amplifies the impact.

QNDX and IQQ will experience exactly the same concentration risk and the same volatility — they track the identical index. Neither fund's lower fee changes the underlying bet.

For New Investors: How to Choose

If you are starting a Nasdaq-100 position from zero in August 2026, the practical decision between QQQM, QNDX, and IQQ comes down to three factors:

First, account type. In a tax-advantaged account (IRA, 401(k)), the switching-cost problem disappears — you can always change later without a tax consequence. That makes IQQ or QNDX's lower cost marginally more attractive, though the AUM and spread concerns still apply. In a taxable account, QQQM's combination of spread efficiency, AUM depth, and four-year operating history is a stronger argument today.

Second, time horizon against the waiver. IQQ's fee advantage is contractually guaranteed only through July 31, 2027. An investor with a 30-year horizon is betting that BlackRock will extend or make permanent the 0.10% rate. That is a reasonable bet given competitive pressure, but it is a bet, not a guarantee. QNDX's 0.10% fee is permanent and has no expiration.

Third, AUM trajectory. QNDX has $24.9 million in assets; IQQ has somewhat more but is still a fraction of QQQM's $101 billion. As both funds grow, their spreads will narrow and their closure risk will diminish. Investors willing to accept current spread costs in exchange for lower annual fees are making a rational trade. Investors who prioritize liquidity, spread efficiency, and a mature operating history today will find QQQM remains the stronger option.

Frequently Asked Questions

Should existing QQQM holders switch to IQQ or QNDX to save on fees?

For most investors holding QQQM in taxable accounts, switching is almost certainly a mistake. The capital gains taxes triggered by selling an appreciated QQQM position will exceed years or decades of fee savings from the 5 basis point difference. The break-even period — the number of years at lower fees needed to offset the one-time tax bill — typically runs to 10 to 30 years depending on the size of the embedded gain. Investors in tax-advantaged accounts (IRAs, 401(k)s) face no such penalty and can evaluate IQQ and QNDX on their merits, though the AUM and spread concerns below still apply.

Is the 5 basis point fee advantage of IQQ and QNDX over QQQM as significant as it looks?

In isolation, 5 basis points per year on a $100,000 portfolio is $50 annually. But the bid/ask spread on QNDX and IQQ is currently 0.04%, compared to QQQM's 0.01% — a 3 basis point spread premium per transaction. For an investor making one annual contribution and one eventual withdrawal, the round-trip spread cost (0.06%) approaches the annual fee advantage (0.05% per year) in less than two years of holding. Additionally, IQQ's 0.10% fee depends on a waiver expiring July 31, 2027; the fund's contractual gross fee is 0.12%. The net fee advantage is real but smaller than the headline numbers suggest.

What happens to IQQ's fee after July 31, 2027?

IQQ's gross expense ratio is 0.12% — the fee that applies if BlackRock does not renew or extend the current waiver. Under the waiver, investors pay 0.10% through July 31, 2027. If the waiver lapses without renewal, IQQ would become more expensive than QNDX (0.10% permanently) and only three basis points cheaper than QQQM (0.15%). BlackRock has strong competitive incentive to maintain the 0.10% rate given State Street's permanent pricing, but investors with multi-decade time horizons should monitor the IQQ waiver status annually.

What is the biggest risk QNDX investors should know about right now?

QNDX held approximately $24.9 million in total assets as of late July 2026 — extraordinarily small for a fund tracking a $10 trillion index. Tiny AUM creates real risks: wider bid/ask spreads than a mature fund would carry, limited market-maker depth during stress events, and potential fund closure if assets do not grow materially. State Street has described QNDX's early flow trajectory as "one of our most successful fund launches," citing positive flows on all but one day since launch, but the fund remains a fraction of QQQM's scale. Investors in QNDX should monitor fund AUM over 12 months.
