Bitcoin ETFs Record $1B Inflow, Signaling Renewed Institutional Interest

U.S. Bitcoin exchange-traded funds (ETFs) saw a massive resurgence in investor demand, recording their largest single-day inflow in five months. According to Glassnode, 11,898 BTC—worth approximately $1 billion—flowed into U.S. Bitcoin ETFs on April 22, 2025. This marks the highest inflow since November 11, 2024, and the most significant spike of the year, suggesting a bullish shift in institutional sentiment.

The surge dwarfs the average daily inflow of just 23 BTC seen across U.S. spot Bitcoin ETFs since January. The April 22 inflow was more than 500 times this average, highlighting a dramatic uptick in buying activity. It also exceeded the historical average of 1,031 BTC per day since the ETFs launched on January 11, 2024, by over 11 times.

The top performers in Tuesday’s ETF inflows included ARK 21Shares (ARKB) with $267.1 million, Fidelity’s FBTC with $253.82 million, and BlackRock’s IBIT at $193.49 million. These strong inflows pushed the total net assets in Bitcoin ETFs to $36.69 billion, based on data from SoSoValue.

Grayscale’s GBTC, despite being among the largest ETFs by volume, lagged behind with just $65.06 million in net inflow. The overall spike in ETF demand coincided with a broad crypto market rebound, as Bitcoin’s price climbed past key resistance levels, approaching $95,000.

This renewed momentum indicates rising institutional appetite for BTC exposure, reinforcing the role of ETFs as a gateway for mainstream adoption. As ETF inflows accelerate, Bitcoin’s bullish narrative gains further traction in 2025.
