Crypto Inflows Hit $3.75 Billion as Ethereum Takes Center Stage

Digital asset investment products experienced massive crypto inflows of $3.75 billion last week, marking the fourth-largest weekly surge on record.

This influx pushed total assets under management to an unprecedented $244 billion, demonstrating growing institutional confidence in cryptocurrency markets.

The United States dominated these flows, accounting for 99% of total inflows at $3.73 billion. Smaller contributions came from Canada ($33.7 million), Hong Kong ($20.9 million), and Australia ($12.1 million).

However, Brazil and Sweden reported modest outflows of $10.6 million and $49.9 million, respectively.

Ethereum’s Remarkable Market Performance

Ethereum emerged as the clear winner, capturing $2.87 billion in inflows—representing 77% of total weekly investment.

This performance brought Ethereum’s year-to-date inflows to a record $11 billion, significantly outpacing Bitcoin on a proportional basis. The inflows represent 29% of Ethereum’s assets under management, compared to Bitcoin’s 11.6%.

This surge coincides with U.S. spot Ethereum exchange-traded funds now holding over 5% of the total ETH supply.

According to on-chain data, these funds control approximately 6.3 million ETH worth $26.7 billion, representing 5.08% of the current supply. Digital asset treasuries control an additional 2% of the total ETH supply.

Meanwhile, $ETH‘s recent rally remained a key market focus after surpassing its highest levels against USD since 2021.

Crypto Inflows by Asset

Bitcoin saw more modest gains with $552 million in weekly inflows, while alternative cryptocurrencies also attracted attention. Solana recorded substantial inflows of $176.5 million, and XRP drew $125.9 million.

In contrast, Litecoin and Ton experienced minor outflows of $0.4 million and $1 million, respectively.

Market Dynamics and Provider Concentration

An unusual aspect of this week’s flows was their concentration within a single provider—iShares—and one specific investment product. This concentration suggests targeted institutional strategies rather than broad market enthusiasm.

However, Monday’s session showed signs of profit-taking, with Ethereum ETFs reporting $196.6 million in net outflows—the second-largest single-day exodus since their launch.

Bitcoin ETFs also experienced outflows of $121.8 million on the same day.

Despite these short-term fluctuations, the overall trend indicates robust institutional adoption of cryptocurrency investment vehicles, with Ethereum leading the charge in capturing investor interest and capital allocation.
