Fastest Growing ETFs of 2026
These ETFs have seen extraordinary growth this year.
Here at ETF.com, we talk a lot about flows into and out of ETFs. Each day, each week and each month, we put together lists of the exchange-traded funds that garner the largest inflows and the largest outflows of assets—an indication of where investors are putting their money to work.
Most of the time, the same batch of ETFs finds itself on these lists. These funds are usually super liquid, extraordinarily cheap and have billions of dollars in assets. For example, the $983 billion Vanguard S&P 500 ETF (VOO) and the $144 billion State Street SPDR Portfolio S&P 500 ETF (SPYM) are among the ETFs that have had the largest inflows so far this year.
No matter how you slice it, their respective year-to-date inflows of $78 billion and $36 billion are sizable. That said, VOO and SPYM aren't necessarily the ETFs growing the fastest.
On an absolute basis they are, but not on a percentage basis. Since the start of the year, VOO has grown from $833 billion to $983 billion—a combination of inflows and price appreciation—equal to a percentage increase of 18%. SPYM has gone from $97 billion to $144 billion, an increase of 49%.
Both have seen impressive growth, especially for their size, but they are nowhere close to the top of the heap.
On a percentage basis, there are myriad ETFs that have grown much faster in 2026. These are ETFs that almost never make our flows lists because they are starting from a much smaller asset base.
In this article, we'll take a look at these fast-growing funds, which, in many cases, are flying under the radar of the ETF investing public at large.
Starting Point
Admittedly, it's much easier for a small fund to register a big percentage increase in its assets. A fund with only $1 million in assets under management simply has to grow to $2 million for its assets to double. Is that noteworthy? Not really.
How about a $1 million fund growing to $50 million? Now that could be noteworthy for some; others might not pay attention until a fund grows even larger, into the hundred-million or even the billion-dollar range.
That's why we've put together two lists: one that showcases the fastest-growing ETFs of the year no matter their starting level of assets, and another that includes ETFs that had $50 million or more in assets at the start of 2026.
Growth is measured in terms of assets as of June 8 compared to what they were at the start of the year. Growth can come from inflows and/or price appreciation.
Interpreting the Growth
ETFs are increasingly being used in model portfolios, which are prepackaged baskets of funds that financial advisors deploy across many client accounts at the same time, so some of the names saw enormous increases in assets thanks to suddenly being included in a popular model portfolio.
Other times, one big institutional investor can move the needle on its own. A single large allocation from a pension fund, hedge fund, or another deep-pocketed buyer can be enough to double or triple the assets of a fund.
Then there are the cases where broad-based interest in a fund catapulted it higher, with no single buyer responsible.
Only ETFs that were trading at the start of the year are included. That means a fund like Roundhill Memory ETF (DRAM), which launched in April, isn't included, even though it's one of the fastest growing funds of all time.
