BlackRock Spot Bitcoin ETF IBIT Rallies 19% in Three Weeks

After the U.S. Securities and Exchange Commission approved spot Bitcoin ETFs in January 2024, BlackRock launched the iShares Bitcoin Trust (IBIT), allowing investors to gain Bitcoin exposure through brokerage accounts. Its significance extends beyond bringing traditional capital into crypto: it could also steer crypto investors toward mainstream funds.

Jay Jacobs, BlackRock’s U.S. head of equity ETFs, said on June 18, 2026, that about three-quarters of IBIT investors had never previously owned an ETF. As of a June 19 report, IBIT had about $48 billion in assets under management and held 765,936 Bitcoin. Some investors subsequently also bought the IVV S&P 500 fund, the BAI AI fund and the IAU gold fund.

BlackRock’s spot Bitcoin ETF, IBIT, is a key channel for traditional capital entering crypto assets, and its flows are often viewed as an indicator of institutional demand. Continued Bitcoin accumulation by the ETF not only reduces circulating supply but may also strengthen upward price momentum and investor confidence.

At the time of the report, IBIT had recorded net inflows of more than 17,000 Bitcoin over the previous week, worth about $1.28 billion at then-current prices, helping BTC break above $73,000. Prediction market Polymarket showed that traders had raised the probability of Bitcoin exceeding $75,000 in March to 84%.
