State of Wisconsin Investment Board Increased BlackRock Bitcoin ETF Holdings: SEC Filing

The Wisconsin Investment Board (SWIB) has increased its investment in BlackRock’s iShares Bitcoin Trust (IBIT), according to a new filing with the U.S. Securities and Exchange Commission (SEC). Submit files Today, as first reported on X by MacroScope.

As of June 30, the board owned 2,898,051 shares worth $98.9 million. This represents a significant increase of 447,651 shares from the 2,450,400 shares reported in May. Notably, the filing also revealed that the board no longer holds any stake in Grayscale Bitcoin Trust (GBTC), a change from May when it reported owning 1,013,000 shares.

Earlier this year in May, SWIB became the first government pension fund to buy a spot bitcoin ETF, marking another major milestone in integrating bitcoin into traditional investment portfolios. The board’s decision to increase its investment in IBIT highlights a growing preference for direct exposure to bitcoin through spot ETFs, reflecting broader institutional confidence in bitcoin’s long-term potential.

Despite the recent bearish price action in Bitcoin, money is still flowing into Bitcoin ETFs, with a total inflow of $243.06 million since July 24.
