Mubadala raises its Bitcoin ETF stake 16% to $566 million

Abu Dhabi’s Mubadala disclosed a 16% increase in its Bitcoin ETF position to $566 million in Q1 2026.

The SEC 13F filing shows Mubadala held 14,721,917 shares of BlackRock’s iShares Bitcoin Trust valued at $565,616,051 as of March 31, 2026. The fund added approximately 2 million shares during the quarter, up from 12,702,323 shares at the end of Q4 2025.

Mubadala manages a global portfolio exceeding $330 billion in assets. The IBIT position has become one of its most visible public market holdings, with the fund obtaining Bitcoin exposure through the regulated ETF structure rather than direct cryptocurrency custody.

Abu Dhabi fund adds 2 million IBIT shares in Q1

Abu Dhabi’s combined IBIT position across Mubadala and Al Warda Investments crossed $1 billion at year-end 2025, marking a milestone for Gulf Cooperation Council sovereign participation in regulated Bitcoin products. The Q1 2026 filing pushes Mubadala’s position past the half-billion dollar mark for the third consecutive quarter.

The accumulation has continued through periods of price weakness. ADIC, the Abu Dhabi entity operating under Mubadala, characterised its Bitcoin allocation as a “long-term diversification strategy,” comparing Bitcoin to gold and saying it expects both to play structural roles in its portfolio as the global economy becomes increasingly digital.

IBIT remains the dominant vehicle in the US spot Bitcoin ETF market. BlackRock’s fund recorded $596 million in net inflows in the most recent reporting week, extending a six-week inflow streak with cumulative assets now at $66.1 billion.

Goldman Sachs disclosed approximately $2.36 billion in total crypto exposure through IBIT and other vehicles in the same 13F filing cycle. Mubadala’s continued buying into declining Bitcoin prices reflects the sovereign fund’s decade-long investment horizon.
