BlackRock iShares Bitcoin Trust Hits Record 806K BTC as Institutional Demand Surges

BlackRock’s iShares Bitcoin Trust (IBIT) has reached a new milestone, accumulating approximately 806,700 Bitcoin (BTC) valued at around $63.7 billion. This achievement marks an all-time high for the largest spot Bitcoin ETF globally and highlights the growing institutional appetite for regulated Bitcoin exposure as BTC trades near the $78,000 level.

The surge follows nine consecutive days of positive net inflows, during which IBIT added nearly 21,500 BTC to its holdings. This steady accumulation reflects increasing confidence among institutional investors seeking exposure to Bitcoin through regulated financial products. IBIT now controls about 49% of total US spot Bitcoin ETF assets, maintaining a significant lead over competitors like Fidelity’s FBTC and Grayscale’s GBTC.

During the first quarter of 2026, the ETF recorded net inflows on 48 out of 62 trading days, bringing in an estimated $8.4 billion. Momentum intensified in mid-April, with inflows of $291.9 million on April 15 and $269.3 million on April 10. These strong inflows helped push IBIT’s total Bitcoin holdings beyond the 800,000 BTC mark for the first time.

Across the broader market, US spot Bitcoin ETFs have rebounded after four months of outflows, collectively attracting around $2 billion over four consecutive weeks. IBIT alone contributed approximately $1.7 billion, reinforcing its dominance in the Bitcoin ETF space.

Despite IBIT’s impressive growth, MicroStrategy has reclaimed its position as the largest corporate Bitcoin holder, now owning 815,061 BTC. The company recently purchased 13,927 BTC for roughly $1 billion, widening its lead over BlackRock’s ETF by about 8,300 BTC.

BlackRock is also expanding its crypto offerings, filing an amended S-1 with the SEC for a new Bitcoin income ETF under the ticker BITA. This proposed fund aims to generate yield using a covered call strategy linked to IBIT. As both BlackRock and MicroStrategy continue accumulating Bitcoin, competition among top institutional holders is expected to intensify in the coming months.
