Documents submitted to the U.S. Securities and Exchange Commission (SEC) indicate that the Abu Dhabi Sovereign Fund (Mubadala) owns 8.7 million shares in the iShares Bitcoin Trust (IBIT) valued at $408.5 million as of March 31 of last year, an increase of 491,000 shares from the previous quarter.

This comes as part of the fund's interest in Bitcoin, as it had previously announced a partnership with Marathon Digital to establish a mining facility in Abu Dhabi.
