Institutional interest in Bitcoin continues to surge, fueling a record inflow into Blackrock’s iShares Bitcoin Trust (IBIT). With over $6.2 billion net inflows in May 2025 alone, the fund surpassed $72 billion in assets under management, significantly impacting Bitcoin’s liquidity and availability on the market. This sustained interest from key players like BlackRock’s internal portfolio managers underscores the growing acceptance of Bitcoin as a diversifying asset for portfolios. Blackrock CEO Larry Fink is a vocal supporter of incorporating Bitcoin into investment strategies, further fueling this trend. The increase in IBIT holdings by 25% compared to Q4 2024 and its impact on related spot Bitcoin ETFs like Fidelity’s FBTC are notable trends to watch.
