Bitcoin and Ethereum ETFs Experience Record Inflows Amid Crypto Price Surge
US spot Bitcoin and Ethereum ETFs have reported their strongest inflow week of 2026, coinciding with a notable rally in cryptocurrency prices. According to data from SoSoValue, Bitcoin ETFs attracted approximately $1.918 billion, while Ethereum funds saw inflows of around $697.2 million, totaling $2.6 billion—the highest combined intake for both assets in nearly ten months.
Throughout the week ending August 21, Bitcoin funds experienced daily inflows, pushing their cumulative net subscriptions since their January 2024 launch to $53.7 billion. This surge follows a significant price increase, with Bitcoin climbing from about $62,300 to nearly $80,000, and Ethereum reaching a seven-month high above $2,500.
The increase in ETF demand is attributed to a combination of macroeconomic factors and supportive regulatory developments. The US Treasury's announcement on August 19 to double the maximum size of liquidity-support buybacks for long-term securities contributed to falling Treasury yields, which in turn boosted demand for risk assets like Bitcoin. Additionally, President Donald Trump's meeting with crypto executives at the White House and the SEC's proposal for a new regulatory framework for crypto fundraising have further fueled investor interest.
Notably, BlackRock's iShares Bitcoin Trust dominated the inflow figures, attracting significant capital on multiple days throughout the week. The overall trading volume for spot Bitcoin ETFs surged by over 219%, reaching $22.1 billion.
As Bitcoin successfully reclaimed its 200-day moving average during this rally, analysts suggest that the influx of ETF capital represents new investment rather than merely a reaction to short position liquidations. Continued positive subscriptions will be crucial in determining whether this momentum can be sustained in the coming weeks.
