The Bitcoin ETF market has seen significant activity, with funds worth $6.4T in AUM being added as authorized participants. Notably, BlackRock and Fidelity reported substantial inflows, with BlackRock's iShares Bitcoin Trust (IBIT) witnessing more than $14 billion of net inflows since its market debut, nearly doubling the category's second-highest flow. Genesis, a troubled crypto lending firm, bought 32,041 bitcoins worth $2.1 billion after selling approximately 36 million shares of the Grayscale Bitcoin Trust (GBTC). This move comes as Bitcoin ETFs, including GBTC, collectively purchased 7,300 Bitcoins worth $502 million this week, including all BTC sold by Grayscale and all newly mined BTC, plus an additional 2,000 BTC. Additionally, Bitcoin spot ETFs have attracted over 4% of the total Bitcoin supply since January 11, with a weekly net inflow of approximately $203 million or about 8600 BTC. BlackRock and Fidelity alone contributed $308.8 million and $83 million, respectively, to the inflows, while GBTC saw outflows of $198.9 million. The market's growth is underscored by BlackRock including major financial institutions like Goldman Sachs and Citigroup as authorized participants for its Bitcoin ETF, highlighting Bitcoin's increasing mainstream acceptance and the rising demand for regulated crypto investment avenues. After securing approval from regulators, the new Bitcoin ETFs gained an average of 42.6%.
