Key Takeaways
- BlackRock’s iShares Bitcoin Trust (IBIT) has accumulated over 662,500 BTC—more than 3% of Bitcoin’s total supply—within 11 months.
- This marks a paradigm shift, as institutional investors increasingly view Bitcoin as a legitimate, long-term portfolio asset.
- The trend raises concerns about the centralization of a decentralized asset and regulatory uncertainty surrounding crypto’s broader adoption.
Since launching its iShares Bitcoin Trust (IBIT) on January 11, 2024, BlackRock has rapidly amassed over 662,500 BTC—accounting for more than 3% of the total Bitcoin supply. At current market prices, this equates to $72.4 billion in Bitcoin exposure, making IBIT the fastest-growing ETF in financial history, outpacing even gold ETFs like SPDR Gold Shares (GLD), which took 1,600 trading days to reach a similar valuation.

This milestone positions BlackRock behind only Bitcoin’s pseudonymous creator, Satoshi Nakamoto, in BTC ownership. As centralized exchanges and major corporate holders lag behind, IBIT could soon become the largest single holder of Bitcoin, significantly impacting the cryptocurrency’s ownership dynamics.
Institutional Validation: Bitcoin in the 60/40 Portfolio
BlackRock’s aggressive entry into Bitcoin isn’t just a short-term play—it reflects a strategic pivot in how institutions perceive digital assets. By framing Bitcoin as an “additive source of diversification,” BlackRock has legitimized the asset class for cautious investors.
The asset manager recommends a 1–2% Bitcoin allocation within traditional portfolios, akin to high-volatility tech stocks. Their rationale? Bitcoin’s scarcity, its role as a dollar-hedge, and its relevance to a digitally transforming economy. The fact that Coinbase Custody holds the private keys for IBIT’s BTC adds an extra layer of institutional-grade security and trust.
This shift is emblematic: once ridiculed by traditional finance, Bitcoin is now embraced by Wall Street’s most powerful players.
A Centralized Future for a Decentralized Asset?
While BlackRock’s ETF has expanded Bitcoin’s legitimacy, it also intensifies the ongoing centralization paradox. Bitcoin was created to decentralize finance, yet more users now access it through centralized entities like IBIT, exchanges, and custodians. This raises philosophical concerns about the true decentralization of Bitcoin’s ecosystem.
Critics argue that institutional dominance could introduce systemic risks—leveraged ETFs, algorithmic trading, and correlation with broader markets—which compromise Bitcoin’s appeal as an uncorrelated hedge. Still, for many investors, the trade-off between ideology and practical usability is worth it.

Regulation Lagging Behind Innovation
The SEC’s approval of spot Bitcoin ETFs was a major win, unlocking institutional participation. However, regulatory clarity remains elusive for the broader crypto market. While Bitcoin enjoys relatively clear treatment, assets like Ethereum and Solana face uncertainty over securities classification.
This legal ambiguity stalls the launch of staking products and DeFi ETFs, preventing institutions from diversifying into other crypto sectors. As BlackRock and other financial giants prepare for deeper crypto integration, consistent and clear regulation will be key to unlocking the next phase of digital asset adoption.
Conclusion:
BlackRock’s massive Bitcoin bet is more than a portfolio move—it’s a signal that crypto is entering a new institutional era. With more than 3% of Bitcoin’s supply now under its control, BlackRock is not only shaping price trends but also influencing the asset’s core identity. Whether this centralization trend strengthens or undermines Bitcoin’s original vision remains an open—and crucial—question.
FAQ: The Impact of BlackRock’s 3% Ownership of Bitcoin Supply
As of June 10, 2025, BlackRock owns over 662,500 BTC through its iShares Bitcoin Trust (IBIT), accounting for more than 3% of Bitcoin’s total supply—valued at approximately $72.4 billion.
BlackRock sees Bitcoin as a legitimate long-term asset with unique diversification benefits. It offers scarcity, potential as a dollar-hedge, and exposure to the broader digital transformation of financial systems.
BlackRock does not custody the BTC directly. Coinbase Custody holds the private keys for IBIT’s Bitcoin holdings, ensuring offline storage and institutional-grade security with insurance backing.
IBIT is the fastest-growing ETF in history, reaching over $70 billion in assets in just 341 days—a milestone that took SPDR Gold Shares (GLD) more than 1,600 trading days to achieve.
Critics argue that BlackRock’s growing BTC stake reflects a centralization of access, not of the blockchain itself. While Bitcoin remains decentralized by design, institutional custody and ETFs may shift influence toward centralized financial players.
