Bitcoin ETFs Flip to $6.3B Inflows in Q3 as Ethereum Roars Back

Bitcoin ETFs, which are traded on US markets, saw a significant turnaround in the third quarter, according to SoSoValue data. After losing around $5 billion in the second quarter, they attracted a net $6.34 billion in inflows. This came as Bitcoin gained 42.7% in the same period, its strongest quarterly performance since the fourth quarter of 2024.

The flows into Bitcoin ETFs were accompanied by strong performance from other cryptocurrencies. Ethereum ETFs, for example, saw approximately $3.05 billion in inflows, reversing about $714 million of outflows in the second quarter. Ethereum itself gained around 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. This took cumulative inflows since launch to about $1.79 billion, with XRP funds ending September with roughly $1.69 billion in assets.

Investors should pay attention to ETF flows, as they provide a cleaner gauge of regulated-market demand than simply watching token prices. A rising cryptocurrency accompanied by persistent ETF creations suggests investors are putting fresh capital to work rather than merely benefiting from mark-to-market gains.
