BlackRock's bitcoin ETF saw inflows of $665M on Monday
BlackRock's bitcoin ETF (IBIT) saw $665M in inflows on Monday, its largest daily inflow since October 2025. Fidelity's FBTC and Grayscale's GBTC saw outflows of $83.6M and $54.9M, respectively. The price of bitcoin did not move significantly despite the inflows. According to Alex Thorn of Galaxy Research, this trend is driven by investors converting spot bitcoin to ETFs for security and other financial activities.
