AMD sheds 9% after SpaceX commits exclusively to Nvidia for AI infrastructure
SpaceX committed its entire AI build to Nvidia hardware on its first earnings call as a public company, and AMD fell about 9% on a day it had a record $11.5 billion quarter on the table. Nvidia is also a SpaceX shareholder.
The Investor · Invest desk
What happened
- SpaceX held its first earnings call as a public company, and Elon Musk said the company will build its entire AI infrastructure exclusively on Nvidia hardware, citing the Vera Rubin architecture.
- AMD shares dropped roughly 9% after the remarks, even though the company had just reported record quarterly revenue of $11.5 billion, up 50% year over year.
- SpaceX booked $2.56 billion of AI-related revenue in the second quarter of 2026, a 247% jump, out of $7.81 billion of total revenue that grew 92% year over year.
- The call also introduced Starmind, a SpaceX and Nvidia program to put Vera Rubin compute payloads on low Earth orbit satellites, with launches scheduled to begin in 2027.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint The exclusivity forecloses 8.6 gigawatts for AMD, the capacity SpaceX has yet to install, none of it ordered. Nobody has modelled the quarters that loss falls in.
- exposure Nvidia's forward orders at SpaceX now sit with a customer it part-owns, so a slip in the 2027 build would hit both the order book and the equity stake.
- contradiction Cryptobriefing credits the 9% to the sourcing decision while reporting no AMD business at SpaceX; if the fall was really about AMD's own guidance, that reading is wrong.
- precedent If Starmind launches on schedule, SpaceX will have picked its orbital compute supplier before a competitor existed in the category.
SpaceX's AI revenue of $2.56 billion in the quarter is about 22% of the $11.5 billion AMD reported for its own [6][3][1]. It is a small customer for AMD. The capacity plan runs to 1.4 gigawatts of compute installed as of June 2026, a target above 2 gigawatts by the end of this year, and 10 gigawatts by the end of 2027 [8][9]. That last figure is 7.1 times what is installed, an addition of 8.6 gigawatts in roughly 18 months, or about 478 megawatts a month [3][4].
$2.56 billion on 1.4 gigawatts works out at about $1.83 billion per gigawatt per quarter, or $7.3 billion a year [5]. Hold that rate and 10 gigawatts implies something near $73 billion of annual AI revenue [6]. It assumes pricing and utilisation survive a sevenfold increase in installed base over 18 months.
Nvidia is a significant shareholder in SpaceX, according to Cryptobriefing [11]. I'd read an exclusivity declaration from a customer that the supplier part-owns as thinner evidence of competitive merit than a 9% move implies. The same report attributes AMD's fall to a high-profile customer publicly choosing the other side. It names no AMD business at SpaceX and no dollar figure for the Nvidia orders [12].
SpaceX's total revenue grew 92% to $7.81 billion, with the AI line at 32.8% of it [5][2]. That line grew 247% [6]; AMD's whole company grew 50% [3]. Nvidia's stock rose between 2% and 3.4% on the news [4].
Starmind, the satellite program announced on the same call, is scheduled to begin launches in 2027, the year the 10 gigawatt ground target lands [10][9].
The record supports three readings. The market priced exclusion from a build with 8.6 gigawatts left in it [3]. Or AMD fell on something inside its own quarter that a single account of a SpaceX call would not cover, and the sequencing did the rest. Or traders marked down merchant suppliers whose forward orders depend on a handful of buyers, and AMD was the liquid way to express it. I lean to the first, while noting that one report of one call cannot separate them, and the test is cheap: if AMD retraces the 9% over the following sessions with no new sourcing news, the sentence was not what moved it [2].
What to watch
- Whether SpaceX clears 2 gigawatts of installed compute by year end, the first check on the 10 gigawatt path.
- Any disclosed dollar figure for SpaceX's Nvidia orders, or the size of Nvidia's stake in SpaceX.
- Whether Starmind's 2027 launch date holds, and whether a rival supplier is ever named for orbital compute.
