BlackRock-Linked Addresses Move $702.25 Million in Digital Assets to Coinbase Prime
Key Facts
TokenPost reported on November 3, 2026, that $702.25 million in digital assets had been transferred from addresses linked to BlackRock funds to Coinbase Prime, in a move involving 7,244 Bitcoin and 63,600 Ether. The platform said the transfer was observed on-chain and did not attribute it to a direct disclosure from BlackRock. The size of the transfer puts fund-linked wallet activity in focus, but by itself does not establish whether the assets were sold or moved for custody or trading purposes. TokenPost did not identify a confirmed purpose for this specific transaction. Coinbase and BlackRock documents provide context on the role of custody and execution services in fund operations, but do not establish the reason for the November 3 transfer.
Coinbase said its Prime Custody service enables clients to trade, finance and hold assets through Coinbase Custody Trust Company, a qualified custodian regulated by the New York State Department of Financial Services. Coinbase describes separate roles within its structure: the custody company holds currencies and cash and facilitates transfers and settlement of trades against delivery, while Coinbase Inc. routes orders to connected trading venues. This distinction shows that assets reaching Coinbase Prime are not, by itself, evidence that they were sold on the market. Describing the move as a transfer to an institutional service also does not reveal whether the assets will remain in custody or enter settlement or trading. Published information did not detail the assets' ultimate destination after the transfer was observed.
The iShares Bitcoin Trust prospectus says bitcoin and cash holdings may be held with the prime execution agent in connection with the creation and redemption of fund units, as well as to cover certain fund expenses. The prospectus also distinguishes between bitcoin held by the custodian and the trading balance at Coinbase Inc. in its capacity as prime execution agent. This structure provides a possible operational context for transfers between wallets and service providers, but does not establish that the observed move was linked to the creation or redemption of units. In an earlier disclosure on the fund's structure, BlackRock said the U.S. Securities and Exchange Commission had allowed in-kind creations and redemptions in July 2025. This provides a framework for bitcoin funds to transact in the assets themselves, without specifying the nature of the November 2026 transfer.
The move follows pressure on flows to U.S.-listed spot bitcoin funds, which recorded net outflows of $643.3 million on October 30, according to CoinDesk. BlackRock's fund known as IBIT accounted for $233.70 million of those outflows in the same session. The report described it as the largest daily outflow since June 25, when investors withdrew $696.3 million. Before the October 30 session, year-to-date net flows had been just over $1 billion, but the daily outflow erased 63.6% of that balance. These figures reflect the fund-flow backdrop at the end of October and do not establish a link to the asset transfer observed on November 3.
A filing by the iShares Bitcoin Trust with the Securities and Exchange Commission showed that redemptions exceeded contributions in the first half of 2026. Distributions for units redeemed totaled $7,236,496,312 in the six months ended June 30, compared with contributions of $4,285,909,689 for units issued. The difference resulted in a net decrease in net assets from capital transactions of $2,950,586,623 over the same period. The filing adds a broader measure of capital movement in the fund during the first half, but does not link those figures to the November transfer. The latest move remains a separate event observed by TokenPost involving addresses linked to BlackRock funds, with no stated purpose.
Market attention is now turning to the U.S. midterm elections scheduled for November 3, followed by the November 6 nonfarm payrolls report on labor market conditions in October, according to CoinDesk. The report said the two events are near-term developments that could affect cryptocurrency markets and interest-rate expectations. This timing places the observed asset movement in a week packed with U.S. events relevant to markets, without establishing that the transfer was a response to any of them. Sources did not estimate the direction of prices or the transfer's effect. Nor was there a direct comment from BlackRock in the available information explaining the reasons for moving the assets.
