Bitcoin ETF Flows Flip to $6.3B Inflows in Q3, Ethereum Leads the Pack

U.S. spot Bitcoin ETFs saw a sharp turnaround in the third quarter, attracting $6.34 billion in net inflows after losing roughly $5 billion in the second quarter, according to SoSoValue data.

The inflows coincided with Bitcoin's 42.7% quarterly gain, its strongest quarterly performance since the fourth quarter of 2024.

However, ETF investors may want to focus on developments beyond Bitcoin, as U.S. spot Ethereum ETFs attracted approximately $3.05 billion in the third quarter, reversing about $714 million of outflows in the second quarter.

Ethereum itself gained roughly 71% during the quarter, substantially outperforming Bitcoin.

The flows were also broadening into smaller crypto assets, with U.S. spot XRP ETFs pulling in approximately $308 million during the third quarter, taking cumulative inflows since launch to about $1.79 billion.

XRP funds ended September with roughly $1.69 billion in assets.

Bitcoin remains the center of gravity, with tracked crypto ETFs holding about $174 billion in combined assets, with Bitcoin funds accounting for nearly $150 billion and Ethereum funds roughly $24.15 billion.
