ETFs in numbers: The $20 trillion revolution

From niche wrapper to the standard vehicle of modern investing, the exchange-traded fund market has grown faster than almost any other corner of asset management. The numbers tell the story.

There are investment trends, and there are structural shifts. In our view, the rise of exchange-traded funds belongs firmly in the second category. In just over three decades, a product that launched as a simple, low-cost way to track the S&P 500 has grown into a $20 trillion global market, shaping how capital flows, how products are built and how all investor types build portfolios.

What makes the ETF story particularly compelling is the pace of change. The fastest-growing segment is active ETFs. The fastest-growing regions are outside the United States. The fastest-growing asset class within ETFs is fixed income. We believe that in each case, the data points in the same direction: the next phase of ETF growth looks meaningfully different from the last one.

This article maps that story in numbers.

1. Rewriting the record books

It took the global ETF industry roughly 16 years, from the launch of the first US-listed fund in 1993 to 2010, to reach $1 trillion in assets under management. It took another seven years to reach $4 trillion. Since then, the market has grown nearly fivefold.

Global ETF assets under management exceeded $20 trillion in early 2026 after adding around $5 trillion in assets during 2025 alone, driven by a combination of strong markets and investor demand.

Demand has been consistent as well as large. As of February 2026, the global ETF industry had recorded 81 consecutive months of net inflows.[1]

In 2025, net inflows into ETFs globally reached $2.4 trillion, almost 3.5 times the amount that flowed into mutual funds.[2] In the US, ETFs now represent approximately 30% of combined ETF and mutual fund assets, up from around 24% in 2023.[3]

2. A global story, with regional nuance

The United States remains the dominant ETF market by a considerable margin, accounting for around two-thirds of global assets.

While the US dominates, the most striking growth in 2025 was happening elsewhere.

Within Asia-Pacific, China ETFs surpassed RMB6 trillion in 2025, overtaking Japan to become the region's largest market.[4] European growth, meanwhile, was driven by expanding product choice and growing retail and institutional adoption.

Looking ahead, estimates suggest the regional gap will continue to narrow. Over a third of European industry executives surveyed by PwC expect European ETF assets to more than double to $5.5 trillion or more by June 2030.[5]

3. ETFs vs mutual fund launches

One of the clearest signals of a structural shift is not where existing money sits, but where new products are being built.

In 2025, ETF launches in the United States grew 45% year-on-year, while mutual fund launches declined. Strikingly, there were nearly ten times as many new active ETF launches in the US as there were new mutual fund launches.

In Europe, the same dynamic is visible in product availability. The number of active ETF products available to European investors is now eight times higher than it was in 2020.[6]

4. The active ETF surge

Within the ETF market itself, the fastest-growing segment by a significant margin is active management. The headline ratio makes the point clearly: active ETFs accounted for approximately 10% of total global ETF assets at the end of 2025 yet captured around 25% of net inflows during the year.

That disproportionate flow share is not a one-year anomaly. In the US, active ETF assets grew at a compound annual rate of 65% from 2020-2024, nearly double the rate of the ETF industry as a whole.[7] Since 2015, their share of US ETF AUM has grown from less than 2% to over 11%.

The acceleration has been supported by regulation. A 2019 SEC rule change in the United States made it significantly easier and less costly to launch and manage active ETFs, removing requirements that had previously acted as a barrier to entry for many managers. The result was a rapid increase in the pace of product development and a virtuous cycle in which growing investor demand encouraged further launches, which in turn attracted more capital.

Industry expectations suggest the momentum will continue. Sixty% of executives surveyed by PwC in early 2026 expect global active ETF AUM to more than double to at least $4 trillion by June 2030.[8]

5. Europe: Earlier on the journey, but catching up quick

For all the momentum behind the global ETF story, Europe remains significantly under-penetrated relative to the United States.

As mentioned, ETFs now account for around 30% of total fund assets in the US. The equivalent figure in Europe is just 12%, with mutual funds and other traditional structures still dominant.[9] The same pattern holds within the active segment: active ETFs represent approximately 3% of total European ETF assets, compared with 10% in the US.[10] Put another way, Europe's active ETF market is roughly where the American market was five years ago.

But the direction of travel is clear, as highlighted by adoption and growth rates.

Longer-term projections are also encouraging. PwC's 2026 survey found that over a third of European industry executives expect regional ETF AUM to more than double to $5.5 trillion or more by June 2030, from $2.6 trillion in mid-2025.[11]

6. Beyond equities: A broadening toolkit

ETFs began life as an equity product. The original 1993 SPDR S&P 500 ETF did one thing: track a stock index. For most of the following decade, that remained the dominant use case. What has happened since is a gradual but accelerating expansion into almost every corner of the investment universe, and the pace of expansion is quickening.

Today, equity ETFs still compose approximately three-quarters of global AUM, with fixed income at 17%. But those proportions are shifting, and the direction of flow tells a more interesting story than the current stock.

Beyond traditional asset classes, gold ETFs attracted $89 billion in inflows in 2025 as gold posted its best year since 1979.[12] Alternatives, options-based strategies, and thematic funds are also growing categories, with buffer ETFs – which use options to limit downside while capping upside – attracting interest from risk-conscious investors.

The newest frontier is digital assets. The approval of spot Bitcoin ETFs in the US in early 2024 brought cryptocurrency into the regulated ETF wrapper for the first time.

What comes next

The numbers above describe a market in transition, with ETFs largely responsible for a product landscape that looks considerably more dynamic than it was a decade ago. The projections for 2030 reflect this:

We believe that what matters is how the growth in ETFs is changing the options available to investors. As the market expands beyond its equity origins and active strategies gain traction, ETFs are becoming an essential component of portfolio construction.
