Spot Bitcoin and Ether exchange-traded funds recorded a combined $1.2 billion in net inflows last week, according to Wu Blockchain’s report on DWF Labs’ market analysis. DWF Labs said this was the third consecutive week in which combined inflows exceeded $1 billion, a sequence not seen since July 2025.
Bitcoin funds accounted for about $986.7 million of the weekly total. The update adds to the flow trend covered in Spot Bitcoin ETFs Record $606 Million in Net Inflows on August 20, Extending Four-Day Streak. In the latest figures cited by DWF Labs, September 3 alone brought $730.8 million into BTC ETFs, making it the third-largest daily inflow of 2026.
Bitcoin ETF assets rise alongside sustained inflows
Total assets under management in spot Bitcoin ETFs rose to $103.3 billion, the report said. DWF Labs placed that amount at approximately 6.32% of Bitcoin’s supply, giving the weekly flow figure a broader measure of the funds’ reported footprint.

The weekly breakdown also shows that Bitcoin products supplied most of the combined BTC and ETH ETF inflows. However, the source does not provide a separate weekly inflow figure for Ether funds or identify individual funds contributing to either asset’s total. The supported conclusion is therefore limited to the reported combined inflow, Bitcoin’s stated portion, and the aggregate BTC ETF asset figure.

Falling coin-denominated open interest shapes the spot view
DWF Labs paired the ETF flow data with a change in coin-denominated Bitcoin open interest. That measure declined from 762,200 BTC in mid-August to 669,600 BTC, even as Bitcoin’s price advanced from around $63,000 to $80,000.
The simultaneous rise in price and fall in BTC-denominated open interest is the basis for DWF Labs’ view that the recent move was driven more by spot inflows than by leverage. In other words, the analysis connects the ETF demand figures with reduced coin-denominated derivatives positioning rather than pointing to expanding open interest as the main explanation.
What the figures establish—and what they do not
The data describe a specific weekly market snapshot: three straight weeks above $1 billion in combined spot BTC and ETH ETF inflows, a $986.7 million contribution from Bitcoin products in the latest week, and one especially large BTC ETF inflow day on September 3. They also record higher total BTC ETF assets and lower BTC-denominated open interest during a price increase.
These figures support DWF Labs’ spot-driven interpretation, but the source does not break down flows by issuer, specify Ether’s exact share, or claim that ETF demand was the only factor behind the rally. The distinction matters because the report presents a market reading based on concurrent flow, price, asset and open-interest data—not a complete account of every force affecting Bitcoin or Ether.
