The State of Wisconsin Investment Board (SWIB), which manages $162 billion in public assets, purchased nearly $100 million worth of Blackrock’s Ishares Bitcoin Trust exchange-traded fund (Nasdaq: IBIT) units and invested an additional $63 million in Grayscale’s bitcoin ETF (NYSE: GBTC) in May 2024, according to its filing. Its latest regulatory submission to the U.S. Securities and Exchanges Commission (SEC) made on Thursday now reveals a $321.5 million position in IBIT alone. The investment not only demonstrates strong institutional demand for BTC, but it also shows that Blackrock’s IBIT is head and shoulders above all other spot bitcoin ETFs on the market. Sure enough, data from sosovalue.com indicates that IBIT was the only bitcoin ETF with positive inflows on Thursday, bringing in $26.21 million. The ETF now holds $56.37 billion in assets as of February 13 and has returned 137.32% year-over-year according to Blackrock’s website. The Fidelity Wise Origin Bitcoin Fund (FBTC) is the second largest bitcoin ETF with just under $20 billion in assets, roughly a third of IBIT’s asset size.
