- BlackRock and MicroStrategy now jointly control more BTC than Satoshi’s estimated holdings
- Over $84M in BTC moved to BlackRock’s IBIT ETF from Coinbase Prime in under one hour
- MicroStrategy added 6,556 BTC using equity proceeds, pushing its holdings past 538K BTC
Two of the largest institutional Bitcoin investors, MicroStrategy and BlackRock, now collectively hold in excess of 1.11 million BTC. The total eclipses the approximately 1.096 million BTC held by Satoshi Nakamoto, and it suggests a trend of corporate dominance among the crypto asset class.
Strategy Expands Holdings With Fresh $555M BTC Allocation
MicroStrategy has acquired 6,556 BTC at an average price of $84,785 per coin, totaling $555.8 million. Its aggregate holdings now stand at 538,200 BTC, valued at over $36.47 billion. “$MSTR has achieved BTC yield of 12.1% YTD 2025,” Michael Saylor stated in a post on April 21.
Strategy shared in its official statement Form 8-K_04-21-2025 that the purchase was financed through equity sales. The company raised $547.7 million via 1,755,000 MSTR shares and $7.8 million through 91,213 STRK shares. These funds were then deployed directly into Bitcoin acquisition activity last week.
BlackRock Adds $84M to IBIT ETF Wallet From Coinbase Custody
Multiple transactions moved BTC from Coinbase Prime’s hot wallet to BlackRock’s IBIT ETF address in under one hour. Three separate 300 BTC transfers and one 54.535 BTC batch totaled over $84 million. The inflows are directly attributed to ETF share issuance tied to recent investor demand.
Each transaction was visible on-chain and confirmed the ETF’s continued spot exposure to BTC through regulated custodianship. According to a report by Bitcoin.com News, BlackRock’s ETF now holds 573,187 BTC, with each coin allocated to shareholders via IBIT shares. All assets are held under a custodial structure with no corporate claim by BlackRock itself.
Institutional Control Grows as Satoshi’s Share Falls Below 5%
BlackRock and MicroStrategy collectively hold 1,111,387 BTC, exceeding the 1.096 million attributed to Satoshi Nakamoto. Arkham Intelligence’s latest estimates remain unchanged, reinforcing their joint control of over 5% of Bitcoin’s total supply. Despite that, the BTC remains encumbered by public shareholders and fiduciary obligations.
BlackRock’s coins support ETF liquidity for global retail and institutional investors, while MicroStrategy’s BTC sits as corporate treasury. Both holdings differ structurally from Satoshi’s dormant, self-custodied wallets mined between 2009 and 2010. Yet their accumulation confirms a definitive shift in Bitcoin’s asset concentration toward institutional power.
