U.S. spot Bitcoin ETFs saw a strong start to August, attracting about $853.5 million in new investments over five straight trading days and reversing the withdrawals recorded during the previous week.
According to market data, Bitcoin ETFs brought in $170.1 million on August 3, followed by $211.5 million on August 4. Demand continued to grow, with inflows reaching $244.4 million on August 5, the strongest day of the week. The funds then added another $128.8 million on August 6 and $98.9 million on August 7.
The five-day inflow streak marked a major turnaround after investors pulled roughly $61.5 million from Bitcoin ETFs the week before. It also came after a volatile end to July, when the funds experienced significant outflows.
BlackRock’s iShares Bitcoin Trust (IBIT) was the main driver of demand. The fund attracted around $693 million during the week, accounting for more than 80% of all Bitcoin ETF inflows. Fidelity’s FBTC also posted solid gains, while several other funds recorded smaller inflows.
By the end of the week, total assets held by U.S. spot Bitcoin ETFs had grown to about $79.5 billion. Since their launch, the funds have attracted more than $52 billion in cumulative net inflows.
The strong start to August is particularly notable because the $853.5 million added in just five trading sessions is nearly five times more than the approximately $172 million collected during all of July.
Ethereum ETFs also had a positive week. The funds attracted around $244.9 million between August 3 and August 7, despite starting the week with a small outflow.
Most of the Ethereum ETF demand came from BlackRock’s ETHA fund, which continued to attract strong investor interest. Total assets in U.S. spot Ethereum ETFs climbed to roughly $10.7 billion by the end of the week.
Combined, Bitcoin and Ethereum ETFs brought in nearly $1.1 billion in fresh investments during the first week of August, showing that investor demand for regulated crypto products remains strong.
Meanwhile, ETF products tied to other cryptocurrencies such as XRP, Solana, and Hyperliquid saw much smaller flows. This suggests that most institutional and regulated investment demand continues to be focused on Bitcoin and Ethereum.
Despite the strong inflows, Bitcoin remained below the $65,000 level during the week. While ETF demand has helped support prices, it has not yet been enough to trigger a major breakout higher.
