According to a newly released 13F filing, the fund now holds $408.5 million worth of shares in BlackRock’s iShares Bitcoin Trust (IBIT).
As of March 31, 2025, Mubadala owned 8,726,972 shares—up from 8.2 million reported just three months earlier. This growing stake comes as U.S. spot Bitcoin ETFs continue to attract massive inflows this May.
Big Money, Big Momentum
Mubadala’s rising exposure to IBIT adds weight to what’s already been a breakout month for Bitcoin ETFs. On May 2 alone, U.S. spot Bitcoin ETFs saw $674.9 million in inflows, followed by $425.45 million on May 5, and $334.58 million on May 9. Just yesterday, another $319.12 million poured in, with BlackRock’s IBIT capturing $232.46 million of that single-day total.
In a 13F filed today, Mubadala, the Abu Dhabi sovereign wealth fund, disclosed owning 8,726,972 shares of IBIT as of March 31, valued at $408.5 million.
That’s an increase from 8,235,533 shares previously reported as of December 31.
This is an important one.

These figures highlight a broader shift: large institutions are not just testing the waters—they’re diving in. For many, Bitcoin ETFs like IBIT offer a regulated, secure, and familiar way to gain exposure to crypto without holding actual coins. And with Mubadala stepping up its position, the signal to other global funds is clear: the time to act may be now.
UAE and U.S. Deepen Crypto Dialogue
Mubadala’s move also reflects a deeper strategy playing out behind the scenes. In March, David Sacks—appointed by President Trump as the White House’s Special Advisor on AI and Crypto—met with senior Emirati officials, including National Security Advisor Tahnoon Bin Zayed Al Nahyan.

Their conversations focused on the crossroads of artificial intelligence, digital currencies, and global investment opportunities. “Fostering collaboration and adopting forward-looking strategies remain essential pillars for driving sustainable growth,” Bin Zayed wrote on X.
This partnership mindset is already showing results. The UAE has rapidly embraced Bitcoin over the last year, from expanding infrastructure to hosting high-profile events like the Bitcoin MENA Conference in Abu Dhabi. At the conference, Eric Trump emphasized how quickly attitudes toward crypto can change, recalling a friend who dismissed Bitcoin, only for his bank to adopt it months later.
