BlackRock has accumulated 17,642 BTC since February of this year

Market lifeline

BlackRock's iShares Bitcoin Trust (IBIT) has purchased an additional 17,642 BTC since February 24, 2026, raising the fund's total BTC holdings to a new record high and representing approximately $1.28 billion in net inflows at current prices (approximately $72,500–$73,000/BTC during the accumulation phase). This massive buying spree, tracked through blockchain analytics firms (Arkham Intelligence, BitInfoCharts) and daily ETF inflow reports, marks one of the strongest multi-week periods of inflows for IBIT since the launch of spot Bitcoin ETFs in January 2024.

• Time: February 24 – March 4, 2026 (trading days)

• Total BTC purchased: 17,642 BTC

• Average cost basis: ~72,600–73,100 USD (estimated from daily creation prices)

• Value in dollars: ~1.275–1.29 billion USD

• Current holdings (as of the close of trading on March 4th): ~612,000–615,000 BTC (exact figures may vary slightly depending on the source due to creation/purchase activity during the day)

• Impact on AUM: This adds approximately $1.28 billion to IBIT's assets under management, pushing total AUM to approximately $44–46 billion.

After a brief lull in late January/early February due to uncertainty surrounding tariffs and macroeconomic volatility, inflows into spot Bitcoin ETFs have surged again. BlackRock (IBIT) and Fidelity (FBTC) have consistently led the way, with combined net inflows exceeding $2.1 billion over the past 10 trading days. BlackRock currently controls approximately 2.9–3.0% of the total circulating Bitcoin supply — making it the largest institutional holder outside of Satoshi-era Bitcoin wallets and early miners.

Institutional investment flows are taking shape.

The continued accumulation of BTC by large asset managers marks a structural shift in the cryptocurrency market. Previously, the Bitcoin market was primarily dominated by individual traders and cryptocurrency-focused funds, but now institutional investment flows are increasingly being influenced.

The demands from organizations have led to several important changes:

• Market liquidity is higher.

• Better long-term capital stability

• Integration with traditional financial markets

• Reduce the dependence of individual investors on speculative trading cycles.

Large asset managers tend to employ long-term allocation strategies rather than short-term trading methods.

Supply dynamics and market impacts

The supply of Bitcoin is essentially limited to 21 million coins, and an increasing portion is being absorbed by long-term holders such as institutional investment funds, corporate hedge funds, and ETFs.

When institutions accumulate large amounts of BTC, this can tighten the circulating supply on exchanges. This dynamic has historically contributed to upward price pressure during periods of sustained demand.

As more and more Bitcoin is moved into institutional custody structures, the market structure of this asset may increasingly resemble traditional commodities or macro assets.

Our review

BlackRock's addition of 17,642 BTC since the end of February is not simply a matter of capital inflow – it's a continuation of the most aggressive fundraising campaign ever by traditional finance for Bitcoin. In a world still grappling with energy shocks, tariffs, and geopolitical instability, the quiet accumulation of BTC by the world's largest asset management firm carries more weight than most headlines. Currently, the accumulation trend remains firmly in place.
