A February 27, 2025 report compared roughly $1.5 trillion in assets described as under his control with an estimated $356 billion for Elon Musk. That was a dated comparison of institutional influence and an individual’s estimated fortune—not evidence that Sheikh Tahnoon personally owned $1.5 trillion, or that the ratio remains true today.
Who is Sheikh Tahnoon bin Zayed Al Nahyan?
Sheikh Tahnoon is Deputy Ruler of Abu Dhabi and a senior UAE official. MGX’s official board biography also identifies him as UAE National Security Advisor and chair of the Artificial Intelligence and Advanced Technology Council. It lists him as chairman of the Abu Dhabi Investment Authority (ADIA), ADQ, International Holding Company (IHC), First Abu Dhabi Bank (FAB), and G42. MGX’s board biography

What did the “four times” comparison actually measure?
Futurism’s February 27, 2025 article put about $1.5 trillion in wealth described as under Sheikh Tahnoon’s control alongside an approximately $356 billion estimate of Musk’s wealth. Those were reported figures from that period, not a current calculation. Futurism’s article

The figures are not like-for-like. Musk’s number was an estimate of personal net worth; the larger figure referred to assets associated with institutions over which Sheikh Tahnoon has leadership or governance roles. “Controls” in this framing should not be read as “personally owns.”
Why chairing an institution does not make its assets personal wealth
Ownership, management and governance are distinct. A chair can have substantial influence over an institution’s direction without owning its balance sheet or being entitled to its assets. ADQ’s prospectus says the Government is its sole indirect shareholder, while official materials identify Sheikh Tahnoon as its chairman. That is direct evidence that the chairmanship and ownership are separate in ADQ’s case. ADQ prospectus
The same distinction matters when interpreting his other chairmanships: those roles help explain his institutional influence, but do not establish that the assets of ADIA, IHC, FAB, G42 or MGX are his personal property. His personal net worth cannot be calculated by adding the assets of institutions he chairs.

In a May 25, 2026 board-meeting release, MGX said it participated as a co-lead in OpenAI’s latest $122 billion funding round and invested in Isomorphic Labs’ $2.1 billion Series B. MGX also said contracted capacity at its portfolio companies was projected to exceed 8 GW by the end of 2026. The capacity figure is a forward-looking company projection, not a result already achieved. MGX’s May 25, 2026 release

MGX CEO Ahmed Yahia Al Idrissi described the company’s strategy as investing “across a widening spectrum of the AI economy, from leading frontier models and platforms to the infrastructure required to scale them globally.” That is the executive’s characterization of MGX’s strategy, not an independent valuation of the portfolio.
Is Sheikh Tahnoon still worth four times Elon Musk?
The available figures do not establish that. The $1.5 trillion and $356 billion comparison dates to February 2025, and the cited materials do not provide a current, comparable total for institutionally controlled assets alongside a current Musk net-worth estimate. Nor do they establish a methodology that would make those two categories equivalent. The “four times” claim should therefore be treated as a dated headline comparison, not a present-day fact about either person’s wealth.
