Ethereum News Today: BlackRock's ETHA Hits $10B in 251 Days, Third-Fastest ETF Growth Ever

BlackRock’s iShares Ethereum Trust (ETHA) has reached $10 billion in assets under management (AUM) in 251 days, securing the third-fastest ascent to this milestone in ETF history [1]. The fund’s rapid growth, driven by surging investor demand for Ethereum exposure, saw it expand from $5 billion to $10 billion in just 10 days—a pace Bloomberg ETF analyst Eric Balchunas described as the “ETF equivalent of a God candle” [2]. This achievement positions ETHA alongside BlackRock’s Bitcoin ETF (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC), which reached $10 billion in 34 and 53 days, respectively [3].

The ETF’s acceleration coincided with Ethereum’s price rally, which peaked near $3,850 in July 2025, its highest level since December 2024 [4]. Balchunas noted that the interplay between inflows and price movements was reciprocal, with robust flows and rising asset values reinforcing each other [5]. Over the first three days of July alone, nine U.S.-listed Ethereum ETFs, including ETHA, generated $1.1 billion in inflows [6]. On July 22 and 23, ETHA attracted $534 million and $426.22 million in net inflows, respectively—ranked among the largest single-day inflows for any ETF [7].

Analysts attribute ETHA’s success to favorable regulatory developments, including the passage of the GENIUS Act, which supports stablecoin innovation, a key Ethereum use case [8]. The fund’s post-SEC approval momentum, combined with growing institutional interest in tokenization and Ethereum’s role in stablecoin ecosystems, has bolstered its appeal [9]. Despite trailing Bitcoin ETFs, which now hold over $140 billion in AUM, Ethereum’s ETF performance signals maturing demand for crypto assets in regulated markets [10].

ETHA’s 251-day timeline to $10 billion outperforms traditional ETFs like JPMorgan’s Nasdaq Equity Premium Income ETF, which took 444 days to reach the same threshold [11]. The fund’s growth underscores Ethereum’s evolving position as a regulated investment vehicle, with analysts noting that the three fastest ETFs to $10 billion are now all spot crypto funds—a first in the 4,400-product ETF industry [12].

The surge in Ethereum ETF inflows has also coincided with broader market shifts, including increased adoption of stablecoin-related treasuries and heightened speculation about Ethereum’s price breakout potential [13]. While Balchunas emphasized that the relationship between price and flows remains complex, he acknowledged the unprecedented speed of ETHA’s growth as a sign of crypto’s integration into mainstream portfolios [14].
