US spot Bitcoin ETFs see $175M inflows, Ethereum ETFs gain $27M

US spot Bitcoin ETFs pulled in $175 million in net inflows on September 4, while their Ethereum counterparts added $26.46 million.

Breaking down the September 4 numbers

The $175 million flowing into spot Bitcoin ETFs on September 4 represents a solid if unspectacular day for the product category. For context, these funds saw approximately $731 million in net inflows just one day earlier on September 3, which marked the largest single-day haul since January 14, 2026.

BlackRock’s IBIT has consistently dominated the flow picture. On September 3, the fund alone attracted roughly $454 million, accounting for about 62% of total Bitcoin ETF inflows that day.

On the Ethereum side, the $26.46 million in inflows on September 4 came after a much stronger showing on September 3, when Ethereum ETFs collectively gathered around $141 million. BlackRock’s ETHA led that earlier session with $72.07 million, followed by Fidelity’s FETH at $65.11 million. Grayscale’s ETHE recorded a modest $6.07 million outflow on September 3.

Combined, Bitcoin and Ethereum ETFs attracted over $200 million on September 4, adding to the roughly $872 million they pulled in the day before.

The bigger picture on cumulative flows

Bitcoin ETFs have now accumulated approximately $55.44 billion in cumulative net inflows since their January 2024 launch. Total assets under management across the category sit around $103.34 billion, representing roughly 6.3% of Bitcoin’s entire market capitalization.

Ethereum ETFs have reached about $13.17 billion in cumulative net inflows with total AUM of approximately $15.92 billion, representing about 5.2% of Ethereum’s market cap.

The September 3 data marked a notable reversal. Just two days prior, on September 1, Bitcoin ETFs had experienced $236.5 million in outflows.

What’s driving the demand

Bitcoin trading above $80,000 and Ethereum clearing $2,500 coincided with the recent inflow surge. Market observers have pointed to dovish commentary from Federal Reserve Governor Christopher Waller as one catalyst behind the recent risk-on mood.
