BlackRock ETF clients purchase $51M in Ethereum

BlackRock’s spot Ethereum ETF pulled in $50.8 million on September 23, making it the single largest contributor to a day that saw $105 million flow into US spot Ethereum ETFs collectively. The iShares Ethereum Trust (ETHA) has become the gravitational center of institutional Ethereum exposure.

Cumulative net inflows into ETHA have now crossed $13 billion. That figure alone accounts for a substantial share of the broader US spot Ethereum ETF sector, which has accumulated net assets exceeding $17 billion.

One ETF, half the market

ETHA’s $50.8 million haul represented roughly 48% of all spot Ethereum ETF inflows that day. Its Bitcoin ETF, IBIT, followed a similar trajectory: launch, dominate early flows, then become the default allocation vehicle for institutions that want exposure without the headaches of self-custody.

The approval of spot Ethereum ETFs in mid-2024 opened the door, but early months were marked by inconsistent flows and periodic outflows. September 2026 appears to mark a return to sustained positive momentum after those earlier rocky stretches.

The staking twist

In March 2026, BlackRock launched ETHB, a staked Ethereum ETF that gives holders yield on top of price appreciation. ETHB has not recorded a single day of net outflows since launch. The product’s consistency suggests that yield-bearing crypto instruments have found a receptive audience among institutional allocators who are accustomed to income-generating assets in traditional fixed income and equity portfolios.

The existence of both ETHA and ETHB creates a two-pronged offering that covers different risk and return profiles. Investors who want pure price exposure go with ETHA. Those willing to accept the additional smart-contract risk inherent in staking, in exchange for yield, opt for ETHB.

Why institutions keep choosing the wrapper

The preference for ETF structures over direct token purchases comes down to a few practical realities. Regulated funds offer professional custody, daily NAV transparency, and seamless integration with existing brokerage accounts. Many institutional mandates restrict investments to regulated, exchange-listed products, and an ETF checks that box in a way that a direct token purchase cannot.

The $17 billion in net assets across all US spot Ethereum ETFs reflects this structural advantage. It’s a market that essentially didn’t exist before mid-2024, and in roughly two years, it has grown to a size that rivals many established commodity ETF categories.
