Total assets in United States exchange-traded funds (ETFs) surpassed $10 trillion for the first time on Sept. 27, propelled in part by inflows of more than $20 billion into cryptocurrency ETFs in 2024, according to data from Bloomberg Intelligence and Morningstar, a fund researcher. 

Investors poured approximately $691 billion into US ETFs so far in 2024, according to Bloomberg. Crypto ETFs accounted for almost 3% of those total inflows.

“We predict [ETFs] will hit $25T in next ten years,” Eric Balchunas, Bloomberg’s senior ETF analyst, said in a Sept. 27 post on the X platform. 

“Normally they double assets every 5yrs but this time it only took 3.7yrs,” he added.
