Historic bloodletting on Wall Street! According to Farside data, US spot Bitcoin ETFs just suffered a colossal loss of $1.79 billion in net outflows in a single week. This is the second worst performance since their launch in January 2024. Between the capitulation of Grayscale (GBTC) and the slowdown of BlackRock, the institutional market therefore seems to be faltering. Simple technical correction or major distress signal before a deeper decline? We take stock.
In brief
- US spot Bitcoin ETFs lost $1.79 billion in the week ending June 26, 2026.
- This is the second worst week in the history of these funds and the 7th consecutive week of net outflows.
- BlackRock IBIT accounts for around 73% of the week's withdrawals, with an average latent loss of 40% for its investors.
- Ethereum ETFs confirm the same trend: marked slowdown in institutional demand.
A historic week for Bitcoin ETFs
Launched in January 2024, the Spot Bitcoin ETF had been greeted as a revolution in the United States. The proof: they had collected tens of billions of dollars in a few months. Enough to propel the price of BTC to historic highs. But, the week of June 26, 2026 marks a turning point.
With $1.79 billion in net outflows in five trading days, these funds have just recorded their second worst weekly performance since their creation. The only worst week remains that of the end of February 2025, which saw 2.61 billion dollars evaporate in a few days.
What fundamentally distinguishes the current situation from the 2025 episode is the duration. In February 2025, the correction was brutal but short. There, seven weeks passed without a single week of positive flows from Spot Bitcoin ETF. For analysts, this persistence constitutes the most worrying signal.
According to the Farside dataThursday June 25, 2026 alone represents $696.29 million in net outflows in a single session. The record of the week! Moreover, almost all of the releases on June 25 came exclusively from BlackRock IBIT. In a single day, this fund saw nearly 7,440 BTC released. This represents approximately $691.7 million.
The negative ETF flow crisis is not limited to bitcoin
THE US Spot Ethereum ETFs recorded $273.34 million in net withdrawals over the same week. Which also marks their seventh consecutive week of releases. June 25 alone represented $82 million in withdrawals from ETH ETFs, while the price of Ethereum plunged to around $1,510. This erases nearly $31 billion in capitalization.
This synchronization between Bitcoin and Ethereum ETF exits is significant. It suggests a movement to reduce overall exposure to crypto-assets on the part of institutional investors.
Beyond ETF feedonchain data also paints the same picture. The Coinbase Premium Index, which measures the price gap between bitcoin on Coinbase and international exchanges, remains in negative territory. A negative premium indicates that US demand is less intense than global demand. This is a bearish signal for American institutional sentiment.
That's not all! Onchain data also shows a net outflow of capital from the Bitcoin network over the recent period, rather than an inflow.
- THE ETF reserves have fallen by more than 63,000 BTC over the last month.
- The total assets under management of all US spot Bitcoin ETFs have fallen from a peak of approximately $170 billion in 2025 to approximately $73 billion today.
The current dynamics of Bitcoin ETFs therefore highlight the crypto market's current dependence on traditional Wall Street capital flows. The next deciding indicator: Week 8, and what the Fed will say between now and then.
