# SPCX Q2 2026 Institutional Ownership The **August 14, 2026** quarterly 13F deadline produced the first institutional ownership picture of [[SpaceX]] as a public company — two months after the largest IPO in history. The totals were large and unsurprising. The **structure** was not. **SpaceX's two largest disclosed institutional shareholders are also two of its largest commercial counterparties.** ## What the filings showed | Holder | Shares | Value | Share of that holder's disclosed portfolio | |---|---|---|---| | [[Alphabet]] | 551.2M | ~$94.1B | **~95%** — essentially its entire disclosed public equity book | | [[NVIDIA]] | ~122.8M | ~$21B | **~33%** — its second-largest holding | | Harvard Management Company | ~12.94M | ~$2.2B | its **largest single US equity position** | | Baillie Gifford | ~51.4M | — | — | | ARK, Fidelity, Saudi Arabia's Public Investment Fund | disclosed positions | — | — | *(Holders other than Alphabet and Nvidia are named as plain text deliberately — they are financial institutions outside this vault's scope, not entities it tracks. See [[Saudi Arabia]] for the sovereign-fund context.)* Alphabet's stake is a legacy position: the **January 2015 $1B investment** made alongside Fidelity, held through eleven years and repriced by the listing. Nvidia's arrived mechanically — its stake in xAI **converted into SPCX shares in the February 2026 merger** ([[xAI-SpaceX Merger]]). ## Why the structure is the story Neither holding is improper, and supplier-shareholder overlap is common in technology. What makes this configuration worth a record is the **specific commitment made ten days earlier**. On the **August 4** earnings call ([[SpaceX Q2 2026 Earnings Report]]), [[Elon Musk]] committed SpaceX to scaling compute from **2 GW to as much as 10 GW by end-2027**, running **exclusively on Nvidia hardware**. That is a multi-year, single-vendor procurement pledge of enormous scale. Nvidia holds **a third of its disclosed public equity portfolio** in the customer that made it. The same quarter's capex line gives the magnitude: **$18.37B of capital expenditure, $15.83B of it AI** — much of which flows to the company that is simultaneously the vault's second-largest disclosed shareholder. **A supplier that is also an owner is not an arm's-length supplier.** Whether that shapes pricing, allocation priority, or terms is unknowable from outside; the point is that the ordinary presumption of arm's-length dealing no longer applies by default, and no related-party disclosure currently treats Nvidia as anything but a vendor. Alphabet's position carries a weaker version of the same shape — it is a counterparty to the [[Google-SpaceX xAI Compute Deal]] while holding essentially nothing else in its disclosed book — but the concentration there is a legacy artifact rather than a live procurement commitment. ## What it settles, and what it opens This closes the question [[SpaceX Watch Log]] had carried since June — *how fast does institutional ownership build?* — with an answer of "immediately and strangely." Combined with the **July 7** [[SPCX Nasdaq-100 Inclusion]], which forced roughly **$4.3B** of index buying into a thin float, SPCX went from no institutional base to a highly concentrated one inside two months. The successor question is sharper: **what does it mean that SpaceX's largest suppliers are also its largest shareholders?** Watch for any procurement disclosure, related-party note, or analyst question that treats Nvidia as a related party rather than a vendor. To date, none has. A second thread worth holding alongside it: the vault separately documents **six members of Congress** buying SPCX ([[Congressional SPCX Stock Purchases]]), several on committees overseeing Pentagon and Space Force contracts. The ownership picture of this company now includes its **largest supplier**, its **largest customer's overseers**, and a **sovereign wealth fund**. ## Connects to - [[SpaceX Investors]] — ownership and capital map - [[SpaceX Q2 2026 Earnings Report]] — the Nvidia-exclusivity pledge and the capex line - [[SPCX Nasdaq-100 Inclusion]] — the mechanical demand that preceded this - [[SPCX First Lock-Up Expiration]] — the supply side of the same float - [[xAI-SpaceX Merger]] — how Nvidia's stake was created - [[Google-SpaceX xAI Compute Deal]] — Alphabet as counterparty - [[Congressional SPCX Stock Purchases]] — the political side of the cap table ## See Also - [[SpaceX]] — company page - [[SpaceX Dossier]] — dossier front door - [[SpaceX Events]] — index of SpaceX events/deals - [[Events Hub]]
