What happened
IBIT, the BlackRock-sponsored spot Bitcoin ETF, booked $195. 6 million in net inflows on Friday, according to flow data compiled by CryptoBriefing. That takes the fund's trailing 30-day net intake to $1.
57 billion, a pace that works out to roughly $52 million per trading day over the window. The buy was executed through IBIT's authorized participants, which deliver physical Bitcoin into the trust in exchange for creation units. BlackRock does not disclose the specific wallets involved, but on-chain researchers have previously flagged Coinbase Prime as the custodian handling IBIT's spot settlement.
Friday's print is not the single largest IBIT day of the year, but it is the heaviest Friday close since the end of August and comes against a backdrop where several competing issuers posted flat or negative numbers.
Why it matters
The daily figure is less important than what it says about concentration. IBIT is now the clearinghouse for institutional Bitcoin exposure in the US, and its intake is routinely larger than the network's daily issuance of roughly 450 BTC. At current prices, Friday's $195.
6 million absorbs well over triple a day's new supply, in a single fund. That changes the supply-demand arithmetic traders have been working with since the halving. A year ago, flows this size were split across the ETF cohort.
Now they're pooling in one vehicle, which means BlackRock's product desk is effectively setting the marginal bid for spot BTC during US hours. The $1. 57 billion monthly total also lands at a moment when macro desks are watching for signs that the Fed's October meeting commentary slowed risk appetite.
