BlackRock’s iShares Bitcoin Trust recorded $733 million in net inflows for the week of April 20 to 24, 2026, leading all U.S. spot Bitcoin ETFs as the category crossed $102 billion in total assets under management for the first time.
TLDR
- IBIT drew approximately $733 million in weekly net inflows, the largest single-fund contribution among all U.S. spot Bitcoin ETFs for the week ending April 24.
- Total U.S. spot Bitcoin ETF AUM reached $102.64 billion by April 24, up from $86.22 billion at the start of the month.
- IBIT holds 811,981 BTC as of April 24, valued at approximately $63 billion, an all-time high for the fund.
- April inflows across all spot Bitcoin ETFs exceeded $2.6 billion, nearly double March’s $1.32 billion total.
- Strategy overtook IBIT as the largest corporate Bitcoin holder after acquiring 34,164 BTC, bringing its total to 815,061 BTC.
- All U.S. spot Bitcoin ETFs collectively hold 1,322,094 BTC, equal to approximately 6.3% of Bitcoin’s fixed 21 million supply.
The week ending April 24 marked the fourth straight week of net positive flows into U.S. spot Bitcoin ETFs. Total weekly inflows reached $823.70 million, with IBIT accounting for $733 million of that figure according to SoSoValue flow data.
Earlier weeks in April delivered $786.31 million for the period ending April 10 and $22.34 million for the period ending April 2. The eight-week cumulative total since February 24 stands at approximately $3.76 billion, reversing a six-month outflow period that began after Bitcoin’s October 2025 all-time high of $126,198.
April’s $2.44 billion in monthly inflows is nearly double March’s $1.32 billion, itself the first positive month of 2026 after net outflows in January and February.
IBIT Holdings at an All-Time High
IBIT holds 811,981.5 BTC as of April 24, 2026, per Bitbo’s institutional treasury tracker. That figure represents an all-time high for the fund, reached after nine consecutive trading days of net inflows that added approximately 21,500 BTC to its balance.
At current market prices, those holdings carry a market value of approximately $63 billion. IBIT commands roughly 49% of total U.S. spot Bitcoin ETF assets, placing it ahead of Fidelity’s FBTC and Grayscale’s GBTC.
The fund recorded net inflows on 48 of 62 trading days during Q1 2026, reflecting structural allocation demand from institutional investors rather than episodic retail activity.
Institutional Capital Allocation Drives the Recovery
Bloomberg Intelligence ETF analyst Eric Balchunas confirmed on April 23 that Bitcoin ETF flows had turned positive across every rolling period he tracks, a condition not present in months. He placed IBIT’s roughly $3 billion in year-to-date inflows in the top 1% of all U.S.-listed ETFs by net flows.
Bloomberg analyst James Seyffart described the buying pattern that began on February 24 as outright directional capital allocation rather than market-neutral basis trading. Inflows held on days when Bitcoin’s price moved sideways, consistent with systematic institutional accumulation rather than momentum-driven positioning.
Over the past eight trading days prior to April 24, Bitcoin ETFs absorbed nearly 19,000 BTC, a rate that substantially exceeded new supply from miners during the same period.
Strategy Overtakes IBIT as Largest Corporate Holder
IBIT’s record accumulation coincides with a structural change in the institutional Bitcoin ownership landscape. Strategy acquired 34,164 BTC in a single transaction, bringing its total to 815,061 BTC and overtaking IBIT for the first time since Q2 2024.
As of April 17, IBIT held 802,823 BTC, leaving Strategy ahead by approximately 12,000 BTC. Strategy added roughly 80,000 BTC in the first four months of 2026 using capital raised through STRC, a perpetual preferred stock issued in late 2025 paying an 11.5% dividend.
IBIT and Strategy represent structurally different demand types. IBIT moves on investor inflows and redemptions. Strategy moves on a capital-raising mechanism that operates independently of ETF sentiment.
Market and Broader ETF Context
Bitcoin traded between $77,800 and $79,420 during the final days of the week, holding above key support levels after consolidating in the mid-to-upper $70,000 range through most of April. The $80,000 level has served as the primary resistance ceiling during the current recovery phase.
Spot Ethereum ETFs added $155 million for the week, their third consecutive positive week. Smaller products tracking Solana and XRP posted inflows of $9.4 million and $15.7 million, respectively. Grayscale’s GBTC continued to register net outflows, with $960.43 million leaving the product year-to-date, confirming that the recovery remains concentrated in IBIT and FBTC.
As of April 27, 2026, total BTC held across all U.S. spot Bitcoin ETF products stands at 1,322,094 BTC, equal to 6.3% of Bitcoin’s total fixed supply.
