Spot bitcoin ETFs snap five-day outflow streak with $85.8 million Friday inflow as ether funds keep sliding

U.S. spot bitcoin ETFs took in $85.8 million on Friday, breaking a five-session run of outflows, according to SoSoValue data. The funds still ended the week with roughly $315.8 million in net redemptions.

The streak that ran through Thursday pulled about $727.4 million from the products. The single worst day was June 5, when the funds shed $325.7 million.

BlackRock's IBIT fund, the largest bitcoin ETF by assets under management (AUM), led Friday's buying with $57.7 million, followed by runner-up Fidelity's FBTC at $18.0 million. None of the funds posted a net outflow on the day, per the data.

The week, however, was a sharp slowdown from recent selling. Bitcoin ETFs lost about $1.7 billion the week before, per the data, and $1.4 billion the week before that, an escalation from the week of May 22, which itself was their worst week since late January with $1.26 billion in redemptions. 

IBIT remains the largest fund, holding $48.7 billion in net assets, with the fund's BTC holdings representing about 3.8% of bitcoin's circulating supply. That figure now sits roughly $13.4 billion below the fund's $62.1 billion in cumulative net inflows, a far wider gap than the $3.7 billion The Block noted in May and a reflection of bitcoin's price decline since.

ETF total net flows have been almost entirely negative over the past month, a significant downward turn for the popular exchange-traded products. 

The price of BTC is currently trading around $64,180, mostly flat in the past 24 hours, according to The Block's Bitcoin Price page. The flows land as the bitcoin ETF complex nears a milestone: The Block reported this week that U.S. spot bitcoin ETFs are set to cross $2 trillion in cumulative trading volume less than two and a half years after launch. 

Spot ether ETFs continue to bleed

Spot ether ETFs went the other way. The funds posted a fourth consecutive day of outflows on Friday with $4.9 million in redemptions, and lost about $14.9 million for the week, though an $82.4 million inflow on Monday offset most of it.

The category's $11.2 billion in cumulative net inflows now tops its $9.2 billion in net assets, leaving the funds about $2.0 billion underwater on a mark-to-market basis. The Block reported in May that ether ETF net assets sat $223 million above cumulative inflows, a cushion that has since turned into a deficit as ether's price fell.

According to The Block's data, the total AUM of spot Ethereum ETFs has fallen below its level from one year ago, with about $9 billion in AUM in mid-June 2025 vs about $7.5 billion in AUM currently. 

Ether is currently trading at about $1,680, also mostly flat in the past 24 hours, according to The Block's Ethereum Price page.
