Net inflows of U.S. spot bitcoin ETFs reached US$517.2 million, a record high since May.
On Wednesday, U.S. spot bitcoin exchange-traded funds (ETFs) recorded a net inflow of US$517.2 million, setting a record for single-day investment in these products since May 4. This strong performance pushed total net inflows to $1.47 billion in August.
Largest weekly inflow since January
Since Monday, the U.S. spot Bitcoin ETF has attracted approximately US$1 billion in net inflows. The figure already marks the strongest weekly inflow since the week that ended January 16, when the funds absorbed about $1.42 billion. Investor interest has grown this week, echoing broader gains in the cryptocurrency market.
This round of capital inflows coincides with a rebound in cryptocurrency prices. According to CoinGecko data, Bitcoin prices approached $72,000 on Thursday, up 11% from the previous 24 hours. Ethereum prices also rose sharply by 19% over the same period, reaching $2,286.

Market drivers: Treasury actions and regulatory policies
Market analysts pointed to several factors behind the rapid inflow of funds and the rebound in prices. On Wednesday, the U.S. Treasury Department signaled that it would expand the repurchase of longer-term government debt. This move has depressed U.S. Treasury yields and the U.S. dollar exchange rate, while benefiting commodities such as gold, silver and Bitcoin.
Jonatan Landing, senior market analyst at PrimeXBT, observed that the Treasury's actions have caused gold and silver to outperform stocks, and the market appears to interpret these buybacks as a monetary event rather than a growth signal. He pointed out that Bitcoin's rally is highly consistent with the trend of gold and silver, reflecting what he calls a "currency devaluation transaction."
In addition to macroeconomic developments, the field of digital assets has also ushered in new legislative attention. At a White House event this week, President Donald Trump urged lawmakers to advance the CLARITY Act. The legislative proposal aims to establish clearer regulatory guidance for the cryptocurrency industry.
(Note: CLARITY Act, a U.S. legislative proposal that aims to provide clearer regulatory guidance and legal framework for cryptocurrencies to reduce the uncertainty faced by market participants and investors in this area.)
Ethereum ETF continues to receive capital inflows
Spot Ethereum ETF also recorded strong capital inflows on Wednesday, totaling US$189.2 million that day, bringing cumulative net inflows this week to approximately US$291.5 million. This growth highlights the growing confidence in Bitcoin and Ethereum, and digital assets are gaining more institutional recognition and demand from retail investors.
Both Bitcoin and Ethereum benefited from macro positive factors and expectations of regulatory clarity, laying the foundation for one of the strongest weeks of capital inflows for cryptocurrency ETFs in months.
