Depth Grid: Nvidia's $10 billion AI bet just turned into a $21 billion rocket company stake nobody knew about

Q: How did Nvidia end up owning SpaceX stock?

Nvidia originally invested roughly 10 billion dollars into xAI's 20 billion dollar Series E funding round in January 2026. When SpaceX acquired xAI in February 2026 in a deal valued at 1.25 trillion dollars, Nvidia's xAI stake converted into SpaceX equity.

Q: How much is Nvidia's SpaceX stake worth now?

The SEC filing valued the stake at approximately 21 billion dollars using SpaceX's June 30 closing price of 170.86 dollars. Since SpaceX's stock has since fallen to around 140 dollars, the position's current value is closer to 17.2 billion dollars.

Nvidia's rank among SpaceX shareholders, behind Musk and Alphabet

Published: August 15, 2026 | Category: Business | By Mahesh

Nvidia's quarterly regulatory filing on August 14 confirmed something the market had suspected but never seen with hard numbers: the world's most valuable chipmaker owns a multibillion-dollar slice of Elon Musk's rocket company. The SEC Form 13F disclosed that Nvidia holds 122.8 million Class A shares of SpaceX, worth approximately $21 billion at the end of the second quarter, according to CNBC.^[1] The stake makes Nvidia the sixth-largest known investor in SpaceX, trailing Musk himself, whose position is worth roughly $906.9 billion, and Alphabet, which holds about $78 billion.

The stake did not come from Nvidia buying SpaceX shares on the open market. It traces back to January, when Nvidia committed roughly $10 billion to a $20 billion Series E financing round for xAI, Musk's AI startup, alongside backers including Valor Equity Partners, the Qatar Investment Authority and Fidelity, according to Yahoo Finance.^[2] That looked like a straightforward AI bet at the time. Then in February, SpaceX acquired xAI outright in a deal valued at $1.25 trillion, and Nvidia's xAI stake converted into SpaceX equity, transforming a cash allocation into one of the most closely watched public positions tied to Musk's combined aerospace and AI business, per Cryptobriefing.^[3]

The Position Has Already Lost Value

The $21 billion figure is a snapshot from the quarter's final trading day, not where the stake sits today, and the gap between the two numbers is itself instructive. SpaceX completed its long-anticipated IPO on Nasdaq in June, selling 555.6 million Class A shares at $135 apiece to raise roughly $75 billion and pricing the company at approximately $1.77 trillion, one of the largest public debuts in history, according to Cryptobriefing's reporting. Nvidia's 13F valued its stake using SpaceX's $170.86 closing price on June 30, the quarter's last trading day. By the time the filing became public on Friday, SpaceX shares had fallen to around $140, cutting the mark on Nvidia's position to closer to $17.2 billion, according to Parameter.^[4] Trading in both stocks stayed muted immediately after the disclosure, with SpaceX shares up 0.35% and Nvidia down 0.12% in after-hours trading, per Cryptopolitan.^[5]

Intel Tells the Same Story From a Different Angle

The SpaceX line item was not the only notable holding in Nvidia's filing, and reading the two side by side is where the real pattern emerges. The same 13F disclosed that Nvidia holds approximately $30 billion in Intel stock at quarter end, a position that has since declined to roughly $22 billion, still a substantial gain on the roughly $5 billion Nvidia invested in Intel less than a year ago, per Parameter's reporting. Combined, the SpaceX and Intel stakes represent more than $50 billion concentrated in exactly two companies, according to Tech Times.^[6]

What makes that concentration worth pausing on is what both companies have separately committed to. Musk said on SpaceX's second-quarter earnings call that the company will exclusively use Nvidia chips in its AI data centers going forward, per CNBC's reporting. Intel has made a parallel exclusivity pledge to Nvidia. Tech Times' analysis of the filing put the structure plainly: Nvidia now holds equity stakes in two companies that have each pledged to make Nvidia their exclusive chip supplier, meaning Nvidia shareholders carry simultaneous exposure to both the chip revenue those companies generate for Nvidia and the equity value of Nvidia's ownership stakes in the companies buying those chips.

Why This Matters Beyond the Balance Sheet

The eight public positions disclosed in Nvidia's 13F total $63.44 billion, and Intel and SpaceX alone account for roughly four-fifths of that entire book, according to Coinotag.^[7] The filing also disclosed a smaller $4.7 billion position in CoreWeave, the GPU-rental neocloud provider whose earnings Depth Grid covered earlier this week, meaning Nvidia now holds direct equity in three separate companies that are simultaneously among its largest chip customers. That is not a new pattern in the current AI investment cycle, but seeing it quantified across a single regulatory filing, with dollar figures rather than general descriptions of relationships, gives the concentration a different kind of weight than the narrative alone conveys.

This connects directly to the circular financing concern Depth Grid flagged when covering Nvidia's separate $500 billion Wall Street financing alliance earlier this month, where the worry was that Nvidia arranging financing for the same customers buying its chips could concentrate risk across the AI infrastructure ecosystem in ways that are hard to see from outside any single company's books. The SpaceX and Intel equity stakes are a variation on the same structural theme: rather than lending capital to customers, Nvidia is holding direct ownership stakes in them, which means Nvidia's own earnings and stock price now carry indirect exposure to how well SpaceX and Intel perform as businesses, on top of the direct exposure Nvidia already has through chip sales to both companies.

What the SpaceX Stake Is Actually Buying

Beyond the balance sheet mechanics, the underlying commercial relationship gives some indication of why Nvidia was willing to build this level of concentrated exposure in the first place. SpaceX has been aggressively building out AI infrastructure, operating GPU clusters that run almost entirely on Nvidia hardware, a relationship that deepened further after SpaceX's acquisition of xAI brought additional compute capacity under the SpaceX umbrella, according to Cryptobriefing. Coinotag's reporting cited separate disclosures indicating SpaceX's compute ambition is expanding from roughly 2 gigawatts of capacity today to nearly 10 gigawatts by the end of 2027, a fivefold increase that, if realized, represents a substantial multiyear demand pipeline for exactly the kind of chips Nvidia sells.

Read that way, the equity stake functions less like a passive financial investment and more like a strategic position designed to keep Nvidia aligned with, and partially benefiting from, one of the largest compute buildouts in its own customer base. Whether that alignment strengthens Nvidia's position or simply concentrates its risk into fewer, larger bets is the question analysts flagged in the Tech Times coverage, and it is not a question this single filing answers on its own.

Common Questions

No. 1: How did Nvidia end up owning SpaceX stock?

Nvidia originally invested roughly $10 billion into xAI's $20 billion Series E funding round in January 2026. When SpaceX acquired xAI in February 2026 in a deal valued at $1.25 trillion, Nvidia's xAI stake converted into SpaceX equity.

No. 2: How much is Nvidia's SpaceX stake worth now?

The SEC filing valued the stake at approximately $21 billion using SpaceX's June 30 closing price of $170.86. Since SpaceX's stock has since fallen to around $140, the position's current value is closer to $17.2 billion.

No. 3: What is the circular investment concern with Nvidia's holdings?

Nvidia holds equity stakes in SpaceX, Intel and CoreWeave, all of which are also major purchasers of Nvidia chips, with SpaceX and Intel having pledged chip exclusivity to Nvidia. Analysts note this means Nvidia shareholders face exposure to both chip revenue and equity value tied to the same set of customer relationships.

No. 4: How large is Nvidia's Intel stake?

Nvidia's 13F filing disclosed an Intel stake worth approximately $30 billion at the end of the second quarter, which had declined to roughly $22 billion by the time of disclosure, still a large gain on the approximately $5 billion Nvidia invested in Intel less than a year earlier.
