BlackRock
World's largest asset manager · spot BTC & ETH ETF custody · @BlackRock
This wallet cluster is the iShares Bitcoin Trust (IBIT) and its ether sibling — the single biggest on-chain footprint in the market. When people say "the ETF bid," this is the address it settles to.
The desk's read
IBIT went from launch to the fastest-growing ETF in history, and the balance here is the physical proof: the bitcoin backing every share sits in cold storage that on-chain data maps to BlackRock. The ether stack is the newer, smaller half of the same machine.
Why it matters for the desk: this holding barely trades — it accumulates. Net creations mean inflows, redemptions mean outflows, and the day-to-day drift you see here is mostly price. It's the cleanest single read on institutional demand that exists on-chain.
Watch the direction, not the number. A quarter where this cluster shrinks in coin terms — not dollar terms — is the tell that the ETF bid has paused.

Not investment advice. Entity labels are on-chain attribution and can be imperfect; a labelled balance may mix personal, treasury and custody wallets. Large balances do not imply intent — some never move.
