ETF market hits $16 trillion as dangerous new merchandise flood the sector

The US ETF market has by no means been bigger or extra difficult to navigate. There was $15.8 trillion parked in 5,401 US-domiciled ETFs on the finish of June 2026.

According to Morningstar Manager Research’s State of US ETFs 2026 report, authored by analysts Zachary Evens and Daniel Sotiroff, CFA, affiliate director of passive methods, greater than 1,000 new funds launched in 2025 alone, and the tempo has not slowed.

What goes into the ETF wrapper more and more bears little resemblance to the index funds that constructed the trade. The Morningstar report attracts a pointy distinction between three generations of ETFs – easy index trackers, lively and factor-based methods, and a more recent cohort of derivative-driven merchandise that the report’s authors describe as resembling playing greater than investing.

And the proliferation of selection has made the choice course of extra consequential than ever as highlighted in a latest InvestmentNews interview with Dimensional Fund Advisors’ global head of investment solutions, Marlena Lee.

Passive nonetheless dominates, however lively is gaining quick

Passively managed, or index-based, ETFs stay by far the most important phase of the US market, accumulating 87.5% of complete ETF property. Three S&P 500 index funds – Vanguard’s VOO, iShares‘ IVV, and State Street‘s SPY – alone account for roughly 17% of all cash in US ETFs, in keeping with the Morningstar information.

But the gravitational pull of active management is reshaping how the industry grows. Actively managed ETFs accounted for 12.5% of all ETF property on the finish of June 2026, with the surge in lively launches catalyzed by the SEC’s adoption of Rule 6c-11, often called the ETF Rule, in 2019, which made it far simpler for lively fund managers to enter the ETF wrapper with out compromising their capital allocation course of.

Active ETF property have crossed $1.47 trillion, rising at a 59% compound annual fee over the previous three years, in keeping with ETF.com. Despite that momentum, efficiency information stay sobering. The most up-to-date SPIVA scorecard, printed in early 2026, discovered that 79% of actively managed large-cap US fairness funds underperformed the S&P 500 in 2025. Over a ten-year horizon, solely 24% of lively ETFs have crushed their benchmarks.

That underperformance file has not slowed asset gathering, partly as a result of not all lively ETFs are attempting to beat the market. The largest suppliers within the lively area – Dimensional Fund Advisors, J.P. Morgan Asset Management, and Capital Group – largely provide systematic or rules-based methods that sit someplace between pure indexing and discretionary inventory choosing.

The mutual fund migration accelerates

Alongside the lively ETF increase, a structural shift in how fund firms distribute their merchandise is reshaping the aggressive panorama and creating new choices for advisors managing purchasers throughout taxable and retirement accounts. Since Guinness Atkinson transformed two funds into ETFs in March 2021, one other 208 mutual funds opted to transform to an ETF format by June 30, 2026.

A extra consequential improvement is the emergence of twin share class funds, which permit each ETF and mutual fund buyers to entry the identical portfolio.

As of late 2025, the SEC had approved twin share class buildings for a number of fund households, and on December 17, 2025, issued a mixed discover to 30 extra companies of its intent to approve their purposes.

A consumer in a brokerage account and one in a 401(okay) can maintain the identical technique with out the advisor managing separate, probably divergent merchandise.

Advisors trying to perceive the portfolio building implications of those adjustments can evaluate InvestmentNews‘ coverage of ETF product trends and advisor portfolio strategies for context on how the market is evolving.

A 3rd era raises the stakes

The fastest-growing ETF launch classes in 2026 embrace trading-leveraged fairness funds with 218 launches within the first half of the 12 months alone, outlined end result ETFs with 65 launches, and spinoff earnings merchandise with 46 launches, in keeping with Morningstar Direct information by June 30, 2026.

Derivative earnings ETFs have attracted vital property. The class picked up roughly $54 billion in web new property in 2025, making it the only hottest class amongst actively managed ETFs that 12 months, with mixed property underneath administration of roughly $130 billion, in keeping with information from J.P. Morgan Asset Management. Defined end result ETFs, which use choices to cap losses in change for capped beneficial properties, occupy a special threat profile however depend on equally advanced mechanics.

The Morningstar report is blunter about what comes subsequent: greater than 50% of ETFs within the pre-launch queue purpose to control the returns of a single inventory utilizing derivatives, and the authors conclude that the majority soon-to-be-launched ETFs look extra like playing than investing.

Tidal was the most important white-label ETF supplier as of June 30, 2026, appearing as listed advisor or subadvisor on 410 ETFs with $60.4 billion in complete property, reflecting how low the barrier to launching a fund has develop into.

Not each third-generation ETF is a product to keep away from, nevertheless. The Morningstar evaluation highlights two tax-focused improvements (box-spread ETFs and funds seeded by Section 351 conversions) as among the many extra promising latest developments for advisors working with tax-sensitive purchasers. Box-spread ETFs package deal a particular choices technique that provides buyers short-term bond-equivalent returns with no distributions, so buyers notice taxable capital beneficial properties solely once they promote the ETF. As of the report date, six such ETFs had been out there within the US market.

What advisors ought to take away

For the vast majority of buyers, the methods that constructed the ETF trade – broad, low-cost, tax-efficient index funds – stay essentially the most defensible core. Active ETFs play a legit function in portfolios, significantly rules-based systematic methods with multi-year monitor data. The derivative-driven phase warrants scrutiny.

US-listed ETF inflows crossed the $1 trillion mark for 2026 by mid-June, lower than midway by the 12 months, in keeping with Bloomberg information – a tempo that Todd Rosenbluth, head of analysis at VettaFi, described as surprising even towards the backdrop of consecutive record-setting years.

The quantity of capital transferring by the ETF market makes the due diligence course of extra essential, not much less. With 5,401 funds out there and lots of extra within the launch queue, the burden on advisors to differentiate between devices designed to serve purchasers and people designed to generate charge earnings for issuers has hardly ever been heavier.
