BlackRock Inc. crypto ETFs
IBIT — iShares Bitcoin Trust
IBIT launched on Nasdaq in January 2024 as one of the first US spot Bitcoin ETFs after SEC approval. It became the fastest ETF in history to cross $50B in AUM, holding spot BTC in a Coinbase Custody Trust structure. The fund charges a 0.25% expense ratio (with a waiver schedule on initial assets) and uses in-kind creation and redemption. IBIT is widely used by registered investment advisors (RIAs), hedge funds and sovereign wealth funds for regulated Bitcoin exposure without dealing with self-custody.
ETHA — iShares Ethereum Trust
ETHA launched in July 2024 after the SEC approved spot Ethereum ETFs. The fund holds spot ETH in cold storage at a qualified custodian and does not currently stake its ETH (so holders forgo staking yield in exchange for ETF wrapper benefits). Since launch ETHA has consistently led the ETH-class category by both AUM and average daily flow.
Market position
BlackRock's iShares Bitcoin Trust competes most directly with Fidelity's FBTC, Grayscale's GBTC, ARK 21Shares' ARKB and Bitwise's BITB. Its dominant position is driven by iShares' distribution muscle across institutional advisors and an aggressive launch fee. On the Ethereum side, ETHA's main rivals are Fidelity FETH and Grayscale ETHE. Investors comparing crypto ETFs typically look at four criteria: AUM and liquidity, expense ratio, custodian and creation/redemption mechanics. BlackRock leads on the first three for the BTC product and on AUM for the ETH product.
