US spot bitcoin ETFs have generally rallied in the past week as bitcoin prices rallied. According to SoSoValue data, the 12 funds recorded a weekly net inflow of $245 million, the third smallest total to date, but an improvement from last week's net outflow of $388 million. However, BlackRock IBIT, the largest such fund by net asset value, posted weekly net outflows for the second consecutive week, despite only four days in both trading weeks due to the holidays. This is the first time the largest spot Bitcoin ETF in the market has seen such a losing streak; its $54.30 billion net asset value (NAV) still far outstrips its biggest rivals Fidelity FBTC and grey release GBTC, both of which have NAVs of around $20 billion.
