BlackRock IBIT Leads $664M ETF Inflows with $284M Daily Surge

• BlackRock IBIT records $284M inflow as eight-day Bitcoin accumulation hits $1.34B.
• Spot Bitcoin ETFs log $664M daily inflow with IBIT leading and FBTC following.
• Sheri Biggs discloses up to $250K purchase in BlackRock Bitcoin ETF shares.

BlackRock‘s spot Bitcoin exchange-traded fund recorded a major inflow on April 17, as fresh data showed continued accumulation through investment products. The firm’s iShares Bitcoin Trust (IBIT) brought in approximately $284 million in a single day, contributing to total net inflows of $664 million across all U.S. spot Bitcoin ETFs.

The activity extends an ongoing trend, with BlackRock purchasing Bitcoin for eight consecutive days. Over that period, total inflows into IBIT have reached about $1.34 billion, indicating an ongoing capital allocation into the asset through institutional channels.

BlackRock ETF Leads Market Activity

Among all spot Bitcoin ETFs, IBIT recorded the largest inflow for the day at $284 million. Its cumulative net inflows have now reached $64.633 billion, maintaining its lead position within the sector. The consistent inflows over multiple sessions point to a steady pace of accumulation rather than isolated demand.

The broader ETF market also reflected increased activity. Combined net inflows across all spot Bitcoin ETFs totaled $664 million for the day, strengthening the scale of capital entering regulated Bitcoin investment products.

Fidelity ETF Follows with Second-Largest Inflow

The second-largest inflow on April 17 was recorded by Fidelity‘s Wise Origin Bitcoin Fund (FBTC), which added $163 million in a single day. With this addition, FBTC’s total net inflows have reached $11 billion. The gap between IBIT and FBTC highlights the concentration of inflows among leading issuers, with BlackRock continuing to capture the largest share of daily allocations.

The ETF inflow data is accompanied by disclosures involving the US Rep. Sheri Biggs, who reported purchasing shares of BlackRocks Bitcoin ETF. The transaction was disclosed in a range of up to $250,000, marking another instance of digital asset-related exposure among U.S. lawmakers.

The sequence of ETF inflows and reported purchases reflects ongoing activity within regulated investment structures tied to Bitcoin.
