| Key Points: – BlackRock accumulated 17,642 BTC since Feb 24, about $1.28 billion. – IBIT channels regulated capital to spot Bitcoin, amplifying accumulation’s significance. – On-chain wallet attributions may reflect operational transfers, not solely net buying. |

BlackRock has accumulated 17,642 BTC, or roughly $1.28 billion, since Feb. 24, according to Lookonchain. The figure is derived from on-chain wallet attribution linked to BlackRock’s Bitcoin exposure and reflects net additions over that window.
The scale matters because iShares Bitcoin Trust (IBIT) is a primary conduit for regulated capital to gain spot Bitcoin exposure. Accumulation at this pace can signal sustained demand, though wallet transfers may also include operational custody movements and internal consolidations rather than purely net new buying.
IBIT and BlackRock Bitcoin ETF inflows: how they work
Spot Bitcoin ETF flows occur through primary-market creations and redemptions handled by authorized participants, while most trading happens in the secondary market. Creations typically involve delivering cash or Bitcoin to the ETF’s custodian; the resulting wallet movements can look like buying pressure even when some transfers are operational.
Industry context helps explain why such inflows are often framed as long‑term allocation rather than short‑term trading. “Sovereign wealth funds are buying Bitcoin incrementally for the long term, not as a trade,” said Larry Fink, CEO, BlackRock.
As reported by U.Today via TradingView, recent on-chain activity tied to BlackRock’s ETF wallets on Coinbase Prime spurred discussion of about $260 million in 24‑hour flows. Such episodes underline that visible transfers can reflect custody rebalancing or liquidity management as much as net demand.
What this accumulation could mean next
At the time of this writing, Bitcoin trades near $73,276, with a 14‑day RSI around 46 and medium volatility near 4.5%. On March 4, Bitcoin briefly breached $71,800 alongside broader digital‑asset gains, as reported by Forklog.
Potential effects on Bitcoin liquidity and volatility
If sustained, cumulative additions of 17,642 BTC can reduce freely tradable supply and deepen institutional ownership via IBIT, potentially improving order‑book resilience. However, large creation or redemption days can still amplify intraday moves when authorized participants source or return coins in size.
The same mechanism works in reverse during risk‑off periods. Based on data from SoSoValue, there have been days when roughly $164 million of net outflows concentrated at BlackRock’s products, reminding investors that ETF‑driven support can ebb.
How to monitor IBIT flows and wallet updates
Analysts typically triangulate authorized participant creation/redemption activity with labeled custodian wallets and exchange settlement flows, then compare against ETF share counts. This process helps separate primary‑market activity from secondary‑market trading.
On‑chain wallet attribution has limits because custodians rotate addresses, aggregate holdings, and conduct internal reshuffles that resemble net flows. As a result, trackers estimating post‑Feb. 24 additions may capture both genuine creations and operational transfers, so figures should be read with appropriate caution.
