Nvidia's $21bn SpaceX stake makes the chip vendor a part-owner of its own customer

Nvidia's latest SEC filing discloses roughly 122.8 million SpaceX Class A shares worth about $21 billion, its second-largest known equity position behind Intel ^[1][2]. It matters because SpaceX has just told investors it will buy Nvidia's next-generation Vera Rubin GPUs and nothing else, which means the seller of the chips now carries the buyer's equity as an asset ^[5][6].

The mechanics are worth spelling out. SpaceX completed its Nasdaq debut weeks earlier, selling 555.6 million Class A shares at $135 each, raising roughly $75 billion at a valuation near $1.77 trillion ^[4]. Nvidia's 122.8 million shares are equivalent to about 22 percent of the Class A float sold in that offering, and about 1.2 percent of the IPO valuation ^[3][6]. Neither report states how or when Nvidia acquired the shares, or what it paid ^[17].

There is also a dating problem in the coverage. Cryptobriefing marks the $21 billion as of June 30, 2026 ^[1]; Cryptopolitan describes it as the current value [c1b]. At the $135 IPO price, 122.8 million shares would be worth about $16.6 billion, and $21 billion implies roughly $171 a share, some 27 percent above the offering price [d_ipo]^[1][2]. That does not reconcile with Cryptopolitan's report that SpaceX is down close to 7 percent since its June debut while Nvidia is up almost 20 percent in 2026 ^[11]. Read the filing itself before treating $21 billion as a mark you can trade against.

On the commercial side, the circularity is explicit rather than implied. On SpaceX's first earnings call as a public company, Elon Musk said the company had decided to build exclusively on Nvidia because it considers the Vera Rubin architecture "the best architecture" and "the best AI computer" ^[5]. He told investors SpaceX expects a "significant allocation" of Vera Rubin GPUs next year ^[6]. SpaceX already runs large GPU clusters almost entirely on Nvidia hardware, a footprint enlarged by its acquisition of xAI ^[7].

Those clusters are being rented out. Cryptobriefing reports a compute-leasing contract with Anthropic valued at $1.25 billion a month and a further reported arrangement with Google covering 110,000 GPUs at $920 million a month ^[8][9]. Taken together that is about $2.17 billion a month, or roughly $26 billion a year of leasing revenue built on hardware bought from a shareholder ^[4]. Nvidia sells the chips, books the revenue, and holds equity in the entity that resells the capacity. Separately, Nvidia has mapped out a $500 billion financing package with Wall Street banks including Goldman Sachs, which CNBC's Jim Cramer called "a monumentally positive change" ^[15][16].

Control at SpaceX is not diluted by any of this. A filing released Thursday put Musk's economic stake at 48.4 percent as of June 30, with sole voting and investment control over 6.42 billion shares worth about $906.9 billion, and more than 82 percent of voting power ^[12]. Musk said on X that the headline figure overstates what is truly his, because part of it "only vests on extremely crazy good outcomes for SpaceX" ^[13]. Trusts where he is trustee hold about 849.5 million Class A and roughly 3.92 billion Class B shares ^[14].

Markets shrugged: SPCX rose 0.35 percent after hours and NVDA fell 0.12 percent ^[10].

What to watch: whether Nvidia's cost basis and acquisition date appear in the full filing, how the Vera Rubin allocation is priced given the shareholding, and whether the Anthropic and Google leasing contracts are confirmed by either company rather than reported second-hand ^[17][8][9].
