The landscape of institutional Bitcoin investment has shifted dramatically as BlackRock’s iShares Bitcoin Trust (IBIT) officially surpasses MicroStrategy in total Bitcoin holdings. This milestone follows a week of robust demand, with net inflows into Spot Bitcoin ETFs reaching $2.23 billion, driven largely by surging investor confidence and strategic capital allocation from major financial institutions.
BlackRock Overtakes MicroStrategy in Bitcoin Holdings
As of March 8, BlackRock’s IBIT crossed a pivotal threshold, accumulating over 196,000 BTC, edging past MicroStrategy’s long-held position as the top corporate Bitcoin holder with approximately 193,000 BTC. This shift marks a turning point in the evolution of digital asset adoption, where traditional finance giants like BlackRock are now outpacing early crypto-native adopters.
The surge was fueled by a $336.3 million net inflow** into IBIT on the final day of the week—equivalent to more than **4,900 BTC**—propelling its total assets under management (AUM) to nearly **$13.5 billion. In comparison, MicroStrategy’s BTC portfolio is valued at around $13.25 billion, based on current market prices.

This development underscores the growing dominance of regulated financial products like Spot Bitcoin ETFs in channeling mainstream capital into cryptocurrency markets. Unlike MicroStrategy, which acquires Bitcoin directly through corporate treasury strategies, BlackRock leverages its ETF structure to offer scalable, compliant exposure to millions of retail and institutional investors.
Just days earlier, on March 7, BlackRock held 191,132 BTC, valued at $12.8 billion, indicating a rapid acceleration in accumulation over a short period. The momentum reflects not only bullish sentiment but also increasing trust in regulated crypto investment vehicles.
Weekly ETF Inflows Signal Strong Institutional Demand
The week beginning March 4 witnessed a powerful resurgence in Spot Bitcoin ETF inflows after a brief slowdown, totaling $2.23 billion across U.S.-listed funds. Investor appetite returned with force, led by two Wall Street titans: BlackRock and Fidelity.
Monday, March 4: Momentum Returns
Markets kicked off the week strongly, with total inflows reaching $588 million**. Both BlackRock and Fidelity reported inflows exceeding **$400 million each, signaling renewed institutional interest. However, Grayscale’s Bitcoin Trust (GBTC) continued to see outflows, shedding $368 million, highlighting a clear shift in investor preference from legacy trusts to newer, more cost-efficient ETF structures.
Tuesday, March 5: Record-Breaking Surge
Tuesday marked a historic day for Spot Bitcoin ETFs, recording an estimated $662.5 million** in net inflows according to provisional data from Farside Investors. Combined inflows into BlackRock’s IBIT and Fidelity’s FBTC surpassed **$900 million, demonstrating deepening institutional commitment to Bitcoin as a strategic asset class.
Wednesday, March 6: Sustained Interest Despite Dip
Although total inflows dipped slightly to $332.4 million, Fidelity maintained strong momentum, reinforcing its position as a key player in the digital asset space. Meanwhile, GBTC outflows persisted, underscoring ongoing capital migration toward lower-fee, more transparent ETF alternatives.
Thursday, March 7: Fidelity Sets New Daily Record
Fidelity’s FBTC made headlines by achieving $473.4 million** in single-day inflows—the largest daily intake for any Spot Bitcoin ETF to date. This performance nearly doubled BlackRock’s daily inflow and pushed the total weekly inflow to **$2.23 billion, one of the strongest weeks since ETFs launched in January 2024.
Why This Shift Matters for the Crypto Market
The overtaking of MicroStrategy by BlackRock is more than a symbolic victory—it reflects broader structural changes in how capital enters the cryptocurrency ecosystem.
- Regulated Access Wins: Investors increasingly favor SEC-approved ETFs over direct corporate holdings due to liquidity, transparency, and integration with traditional brokerage platforms.
- Scalability Advantage: ETFs can absorb large volumes of capital without balance sheet risk, unlike corporations that must finance purchases through debt or equity.
- Market Maturation: The rise of asset managers like BlackRock and Fidelity signals that Bitcoin is being treated as a legitimate long-term store of value within mainstream finance.
These dynamics suggest that future price movements may be increasingly influenced by ETF flows rather than whale transactions or mining activity.
