BlackRock Dominates Inflow Share

U. S. spot Bitcoin ETFs attracted $440.8 million in net inflows across four trading days ending October 29. The surge came just before a sharp sell-off triggered by the $6.3 billion Binance hack. BlackRock’s IBIT fund captured the bulk of the money, with $410.6 million flowing into that single product. The remaining $30.2 million spread across other U. S. Bitcoin funds.

BlackRock’s IBIT accounted for 93% of the four-day total. That concentration highlights investor preference for the largest and most liquid Bitcoin ETF. The fund’s dominance reflects its status as the market leader in U. S. spot Bitcoin exposure. Other issuers like Fidelity and Grayscale saw smaller but meaningful inflows during the same window.

Will Hack Fears Reverse ETF Momentum?

The Binance hack struck on Friday, wiping out $6.3 billion in assets. That loss triggered a broad sell-off in crypto markets. Bitcoin prices dropped sharply in the hours following the breach. ETF inflows that had built over four days now face pressure from renewed risk aversion. Traders and institutional investors are reassessing their exposure. The hack raises questions about custody security and exchange resilience.

The immediate aftermath shows mixed signals. Some investors are exiting crypto positions to protect capital. Others see the dip as a buying opportunity. ETF flows will be the key indicator of whether institutional confidence holds. If outflows follow the hack, it could signal deeper de-risking. Analysts note that ETF products provide a regulated alternative to direct exchange holdings, which may soften the blow. The next few days will reveal whether the $440.8 million inflow trend reverses or holds firm.

Market Reaction and Outlook

How much did BlackRock’s IBIT capture of the four-day ETF inflows? IBIT took in $410.6 million, representing 93% of the total $440.8 million.
