US spot crypto ETF inflows drop 80% to $65M on Monday

After a week that saw Bitcoin ETFs alone vacuum up $2.4 billion in net inflows, the combined haul across all US spot crypto ETFs shrank to just $64.8 million on Monday. That's roughly an 80% decline from the previous Friday's totals, spanning funds tied to Bitcoin, Ether, Solana, and XRP.

The $64.8 million in combined inflows on Monday was split across four asset categories, each contributing positive flows. Bitcoin products pulled in somewhere between $31 million and $135 million depending on the reporting source, with Farside Investors and The Block each capturing slightly different snapshots of the day's activity.

Ether ETFs drew $87 million. Solana products attracted $86.7 million. XRP funds added $21 million.

For the week ending September 25, Bitcoin ETFs had recorded $2.4 billion in net inflows. That was the strongest single-week performance since October 2025, and it pushed year-to-date flows for Bitcoin ETFs back into positive territory after a stretch of outflows earlier in the year.

Cumulative net inflows into US spot Bitcoin ETFs now sit at approximately $57.6 billion, with total net assets across the category hovering around $108 billion.

Ether and Solana products each attracted more capital than most individual Bitcoin fund filings on the day. The introduction of dedicated spot products for Solana and XRP has opened new doors for institutional allocators who want crypto exposure but prefer the regulatory packaging of an ETF. On a day when total flows dropped 80%, Solana ETFs still pulled in nearly $87 million.
