Mubadala Investment Company, Abu Dhabi's roughly $300 billion sovereign wealth fund, files a U.S. 13F that looks like almost no other large institution's: a single position accounts for nearly the entire reported book. About $18.82 billion — 92% of its $20.49 billion U.S. holdings — sits in its controlling stake in GlobalFoundries, the semiconductor foundry Mubadala took public in 2021 and still majority-owns. The remaining 8% is small but revealing, sketching where a Gulf sovereign fund is placing its forward-looking technology bets. This is not a diversified portfolio in any conventional sense; it is a strategic corporate holding plus a handful of satellite positions. Reading it as a stock-picker's book would miss the point. The 13F is really a window into one anchor investment and a few deliberate, smaller wagers on the future of computing. The GlobalFoundries anchor The foundry stake defines the filing. Mubadala holds roughly 423 million GlobalFoundries shares, a position it trimmed about 6% during the first quarter of 2026 but that still dwarfs everything else it owns in U.S.-listed form. As a controlling shareholder, Mubadala's stake is a strategic, long-horizon holding tied to its broader push to build Abu Dhabi into a technology and semiconductor hub — not a quarter-to-quarter trading position. Because one stock is 92% of the book, Mubadala's reported 13F value effectively tracks GlobalFoundries' share price. That explains why the reported total has swung between roughly $17.5 billion and $24.7 billion over the past two years even as the underlying position barely changed — when a single holding is the portfolio, the portfolio moves with that holding. The satellite bets: AI chips and crypto The smaller positions are where Mubadala's strategic interests show. Arm Holdings, the chip-design IP company at the heart of mobile and increasingly AI computing, is held at $208.3 million, and Micron Technology, the memory maker critical to AI servers, was doubled to a small $14.9 million stake. Together with the GlobalFoundries anchor, these form a coherent semiconductor and AI-infrastructure theme. The most eye-catching satellite is a spot-Bitcoin ETF position, raised 16% during the quarter to $565.6 million — making it the second-largest reported holding behind GlobalFoundries. A sovereign wealth fund holding a meaningful spot-Bitcoin ETF stake is a notable signal of institutional and sovereign comfort with digital assets as a portfolio allocation. Alongside a couple of other small holdings, the satellite book reads as a series of measured bets on computing, AI hardware, and digital assets layered on top of the strategic foundry stake. Reading a sovereign wealth fund's filing Sovereign wealth funds occupy a distinct place in 13F data. Unlike passive index funds or market makers, they have genuine investment discretion, so their positions carry real intent. But their U.S. 13F is often only a sliver of a globally diversified balance sheet — Mubadala's hundreds of billions are spread across private equity, real estate, infrastructure, and foreign-listed equities that never appear in a U.S. filing. What the 13F captures here is essentially Mubadala's U.S.-listed equity sleeve, dominated by the one company it controls. The position count rose from 64 to 72 over the quarter, a modest broadening at the margins, but the structure is unchanged: one strategic anchor and a small set of thematic bets. For a sovereign fund, that concentration reflects a mandate — building and holding a national semiconductor champion — more than a market view. What it signals For investors who track institutional positioning, Mubadala's first-quarter filing is less a portfolio to mine for ideas than a statement of strategic priorities. The GlobalFoundries anchor signals a sovereign commitment to semiconductor manufacturing; the Arm and Micron positions extend that into chip design and memory; and the spot-Bitcoin ETF stake marks a deliberate, sovereign-scale allocation to digital assets. The actionable read is thematic: when a Gulf sovereign fund concentrates its U.S. equity book in chips and adds to a Bitcoin ETF, it is telling you where one of the world's largest pools of patient capital sees the next decade. FAQ Why is Mubadala's 13F almost entirely one stock?About 92% of its U.S. 13F is its controlling stake in GlobalFoundries, the semiconductor foundry Mubadala took public in 2021 and still majority-owns. It is a strategic, long-horizon holding rather than a diversified portfolio. What is Mubadala's second-largest holding?A spot-Bitcoin ETF position worth about $565.6 million, raised 16% during the quarter — a notable allocation to digital assets by a sovereign wealth fund, sitting behind the GlobalFoundries anchor. Does Mubadala's 13F show its whole portfolio?No. The filing captures only its U.S.-listed equity sleeve. Mubadala's roughly $300 billion in assets is spread across private equity, real estate, infrastructure, and foreign-listed equities that do not appear in a U.S. 13F. What technology bets is Mubadala making?Beyond its GlobalFoundries foundry stake, it holds Arm Holdings in chip design and doubled a small Micron position in memory, alongside a spot-Bitcoin ETF — a semiconductor, AI-infrastructure, and digital-assets theme. ## FAQ ### Why is Mubadala's 13F almost entirely one stock?
