Net outflow from spot Bitcoin last week [BTC] ETFs totaled $1.257 billion. The last time such a weeklong outflow trend occurred was in December 2025.
On May 18, Bitcoin ETFs saw outflows totaling $648.6 billion, with BlackRock’s IBIT seeing the largest outflows at $448.4 million.
Bitwise’s BITB, Invesco’s BTCO, Franklin Templeton’s EZBC, VanEck’s HODL and Fidelity’s FBTC were among the other asset managers to record outflows.
For the others there were no flows.
Have other days of the week also recorded this massive outflow?
Despite a decline in outflows on May 19, total outflows for BTC ETFs still amounted to $331.1 million, with IBIT recording outflows of $325.6 million.
The other asset managers saw no flows, while two other asset managers only saw a slight outflow. A similar trend was observed on May 20 and 22, when outflows of $70.5 million and $105.2 million were recorded respectively.
However, as of May 21, only IBIT experienced outflows of $103.7 million, while ARKB was the only entity to record inflows of $2.8 million.
What does the price action tell us?
Looking at the price data, it appears that the outflows from the ETFs caused the price of Bitcoin to drop from $78,000 to $76,000.
However, the price managed to maintain its momentum and managed to avoid falling below the $75,000 support level despite this decline. The price remained stable even after US President Donald Trump’s announcement about the peace deal with Iran.
This indicated that the price drop was a passing fad rather than a long-term trend.
The fact that Bitcoin was trading at $77,383.00 at the time of writing indicates that bullish momentum is already returning.

While the Ethereum [ETH] The ETF lagged behind the BTC ETF, the outflow was not limited to one week. On the contrary, the ETH ETF experienced outflows from May 11 to 22.
