preCharge News CRYPTO — The State of Wisconsin Investment Board (SWIB) appears to have reduced its exposure to the Grayscale Bitcoin Trust exchange-traded fund while adding to its position in Blackrock’s iShares Bitcoin ETF.

A new filing with the U.S. Securities and Exchange Commission (SEC) indicates SWIB holds 6,060,351 shares of BlackRock’s IBIT.

With the fund trading at $55.33 at time of writing, that means SWIB’s IBIT exposure currently stands at more than $335.3 million.

In a previous filing back in May, SWIB reported owning only 2,450,400 shares of IBIT. However, the May filing indicated the investment board also held 1,013,000 shares of Grayscale’s BTC ETF (GBTC), which were collectively worth around $57 million at the time. In filings submitted in November and this week, SWIB didn’t disclose any GBTC holdings.

The State of Wisconsin Investment Board is a state agency managing investments for public retirement and trust funds. It has diversified investments, including cryptocurrency, Coinbase, Marathon Digital, Riot Platforms, Block, Cipher Mining, Cleanspark, Microstrategy and other traditional financial vehicles.

IBIT is the largest Bitcoin ETF, with $56.38 billion worth of assets under management (AUM), according to data from Coinglass. Fidelity’s FBTC is second with $20.19 billion in AUM, and GBTC ranks third, with $19.28 billion.

The SEC greenlit the first spot market Bitcoin ETFs in January 2024, bringing in billions of dollars worth of inflows to the top digital asset by market cap. The regulator subsequently approved Ethereum (ETH) ETFs for trading in July.
