US Bitcoin ETFs see largest single-day inflow in over three months

Bitcoin ETFs attract $517 million in one day

US spot Bitcoin exchange-traded funds (ETFs)—investment funds that track the price of Bitcoin and trade on traditional stock exchanges—recorded $517.2 million in net inflows on August 19. This is the largest single-day investment since May 4, 2026.

The inflows pushed the total for August to $1.47 billion. Since Monday, August 17, the funds have taken in about $1 billion, marking their strongest weekly performance since mid-January.

Key figures from the latest ETF inflows

• $517.2 million: Net inflows into US spot Bitcoin ETFs on August 19.
• $1.47 billion: Total net inflows for August so far.
• $1 billion: Inflows since August 17, the strongest week since January 16.
• $291.5 million: Net inflows into spot Ether ETFs this week.

What drove the surge in inflows

The inflows coincided with a rise in crypto prices. Bitcoin traded near $72,000 on August 20, up 11% in the last 24 hours. Ether, another major cryptocurrency, rose 19% to $2,286.

Two factors were highlighted as potential drivers:

• A US Treasury decision to expand buybacks of longer-dated government debt, which analysts said pushed yields and the US dollar lower.
• Renewed attention on crypto regulation after President Donald Trump urged Congress to advance the CLARITY Act, a proposed law aimed at clarifying crypto rules.

Jonatan Randin, a senior market analyst at PrimeXBT, told Cointelegraph that the Treasury’s move was seen as a currency event rather than a growth signal. He noted that Bitcoin moved in line with gold and silver, which often rise when investors expect currency debasement.

What is confirmed about the ETF inflows

• US spot Bitcoin ETFs recorded $517.2 million in net inflows on August 19, the highest since May 4.
• August net inflows reached $1.47 billion.
• Bitcoin traded near $72,000, and Ether rose to $2,286 on August 20.
• Spot Ether ETFs logged $189.2 million in net inflows on August 19.

What remains unclear

• The exact impact of the US Treasury’s debt buyback program on crypto prices is still debated among analysts.
• It is not confirmed whether the CLARITY Act will pass or how it might affect future ETF inflows.

Why this matters for crypto investors

The strong inflows suggest growing investor interest in Bitcoin and Ether through regulated ETFs. These funds allow traditional investors to gain exposure to crypto without directly holding the assets. The recent price rally and regulatory developments may have contributed to this trend.
