BlackRock dominates, adding 3,636 BTC yesterday BlackRock added a record 10,249 BTC on Monday and over 19,000 BTC since the start of the week Other major funds, including Fidelity and Grayscale, showed fluctuations or outflows Ark/21 Shares lost 4,823 BTC over the same period — the largest negative result of the week The growth in total sector holdings came exclusively from IBIT BlackRock dominates, adding 3,636 BTC yesterday, a record 10,249 BTC on Monday, and over 19,000 BTC since the start of the week. Meanwhile, other issuers, including Fidelity, Grayscale, and Ark, either saw outflows or remained flat — making IBIT the only driver of institutional Bitcoin demand this week. More on IBIT’s Clear and Visible Dominance IBIT continues to follow its strategy of prioritizing and accumulating Bitcoin, largely disregarding market volatility and standing out against other ETFs.

Specifically, we see that IBIT kept buying Bitcoin throughout this week: April 28: +10,249 BTC April 29: +2,273 BTC April 30: +2,841 BTC May 1: +3,636 BTC As a result, IBIT has brought its holdings to 607,685 BTC — several times more than its closest competitors — Fidelity with 198,640 BTC and Grayscale with 191,151 BTC. This becomes especially apparent when looking at this week’s dynamics among competing funds: The second-largest fund, Fidelity FBTC, showed inconsistent activity: after an outflow of –1,462 BTC on April 30, it recovered only partially with +264 BTC on Thursday. Grayscale GBTC followed a similar pattern: after losing –340 BTC on April 30, it added +166 BTC on May 1 — without any clear upward trend.

Ark/21 Shares (ARKB) consistently posted daily outflows: April 28: –2,389 BTC April 29: –140 BTC April 30: –1,391 BTC May 1: –903 BTC Total net outflow: –4,823 BTC All of this points to the fact that 84% of all net inflows into the Bitcoin ETF sector this week came from IBIT alone, while competitors either showed no significant inflows or recorded net outflows. Conclusion BlackRock continues to dominate the U.S. market — with a significant lead and a more aggressive accumulation approach — and is also preparing to expand into the EU market. As the only driver of growth in the sector, it continues to attract even more investor attention and strengthen its dominance further, though, of course, there are off days even for IBIT.
