The U.S. Bitcoin ETF market is witnessing unprecedented growth, with recent launches becoming the most successful in ETF history. Spot Bitcoin ETFs now hold nearly $30 billion in assets, with BlackRock's iShares Bitcoin Trust (IBIT) leading by managing over 228,000 BTC, surpassing even Microstrategy's holdings. This surge is attributed to significant inflows, including a record $2.9 billion in a single week, pushing the year-to-date inflows to $13.2 billion, surpassing the total inflows of 2021. BlackRock and Fidelity's Bitcoin ETFs have emerged among the top 5 ETFs by total inflows, highlighting the growing investor interest. Despite this, Grayscale experienced the largest outflow to date, with $643 million worth of Bitcoin withdrawn, signaling a shift in investor preference towards other ETFs. The average trade size for IBIT, around $13,000, indicates substantial nonprofessional investor participation. Investment advisors are beginning to allocate an average of 3.5% of Bitcoin ETFs to client portfolios, suggesting a cautious yet growing acceptance among financial professionals. Notably, there were +30K BTC netflows last week, and the ETFs have accumulated 450,000 BTC. Two spot Bitcoin ETFs are now in the top 6 of all ETF inflows this year. There was $2.5B of net flow for Bitcoin ETFs last week and a significant $1.4 billion withdrawn from Coinbase. Additionally, 9,600 Bitcoin were withdrawn from GBTC.
