U.S. spot cryptocurrency exchange-traded funds (ETFs) recorded substantial net inflows of approximately $173.8 million on March 11, 2026. According to data, spot Bitcoin ETFs added 1,629 BTC, valued at around $115 million, while spot Ethereum ETFs purchased 27,480 ETH, worth about $57 million.
Leading the buying activity was asset management giant BlackRock, whose iShares Bitcoin Trust (IBIT) acquired 1,630 BTC. Fidelity's Wise Origin Bitcoin Fund (FBTC) followed with 218 BTC. Notably, Grayscale Bitcoin Trust (GBTC), which has often seen outflows, sold 155 BTC but was a net buyer of Ethereum. The day's Bitcoin ETF purchases equated to roughly four days' worth of newly mined Bitcoin supply, underscoring robust institutional demand.
In a parallel and strategically significant development, BlackRock's iShares platform has prominently featured its proposed spot Ethereum ETF with staking capabilities on its homepage. The product, tentatively tickered ETHB, represents a novel structure for U.S.-listed ETFs as it incorporates a mechanism to stake the fund's Ether holdings to generate rewards for shareholders.
This prominent placement, first noted by observers in March 2025, is a rare move for iShares and signals BlackRock's high confidence in the product's eventual approval and market potential. The move follows an amended S-1 registration statement for the fund submitted to the U.S. Securities and Exchange Commission (SEC) in February 2025.
"iShares rarely highlights unlaunched products with such prominence," noted Nate Geraci, President of The ETF Store, emphasizing the strategic weight of the action. The SEC's review is ongoing, with regulators scrutinizing market manipulation concerns, custody solutions, and the specific mechanics of Ethereum staking within a regulated fund. Several other asset managers, including Fidelity, Grayscale, and Ark Invest, have similar applications pending.
Analysts view BlackRock's homepage strategy as a multi-faceted signal: it demonstrates serious institutional commitment to the SEC, prepares BlackRock's vast client base, and accelerates the legitimization of crypto within traditional finance. The approval of a staking-enabled Ethereum ETF could unlock significant institutional capital currently hesitant due to operational complexities.
