Bitcoin and Ethereum ETF Inflows Hit Highest Since Early 2024

The crypto market continues to boom as Bitcoin (BTC) and Ethereum (ETH) spot ETFs recorded net inflows of over $1 billion on May 22, 2025 – marking their highest level since November 2024. The main driver was the Bitcoin price setting a new all-time high, combined with rising expectations for institutional investment products based on digital assets.

Bitcoin ETFs: Net Inflows Near $1 Billion, BlackRock Overtakes Binance
Inflows into Bitcoin ETFs accounted for the bulk of the total, with $934 million inflows in a single day – the biggest increase since January 17. The total assets under management (AUM) of Bitcoin spot ETFs has now reached $104 billion, cementing the investment class’ place in institutional investor portfolios.

Among them, BlackRock's IBIT fund continues to lead the increase, currently holding 651,620 BTC. This milestone officially helps BlackRock surpass Binance, becoming the second largest Bitcoin holder in the world, after the inactive cold wallet believed to belong to Satoshi Nakamoto (with 1.123 million BTC). Following is Michael Saylor's MicroStrategy, currently holding about 576,000 BTC.

Ethereum ETF: 5 consecutive days of increase, cash flow peaks at $110 million
Not far behind, Ethereum ETFs also recorded net cash flow of up to $110 million on May 22 - the highest level since February 4. Notably, Grayscale's ETHE fund played a leading role with $43.7 million in net inflow.

This is the fifth consecutive day that Ethereum ETFs have attracted positive cash flow, reflecting the growing confidence of institutional investors in ETH's long-term prospects. Total assets under management of Ethereum ETFs now stand at $10.07 billion.

This strong performance comes after ETH’s 44% price increase in the first half of May, despite traditional equity markets being pressured by concerns over US debt and tax policy.

Positive signal for the entire crypto market
The fact that crypto ETFs are attracting large inflows amid macroeconomic uncertainty shows the resilience of the crypto market, especially when Bitcoin hit a new all-time high of $111,970 on May 22.

The continued interest of institutional investors – reflected in record inflows into ETFs – is a clear demonstration of the trend of legitimizing and popularizing digital assets in the global financial system.
