SpaceX Just Exposed the Biggest Risk in Your AI Strategy

Elon Musk said SpaceX will build exclusively on Nvidia chips going forward, dropping AMD entirely, sending AMD stock down 7 percent today.

SpaceX held its first earnings call as a public company on August 4, 2026. Revenue hit $7.8 billion, up 92 percent year over year. AI-computing rental revenue grew sevenfold.

CEO Elon Musk used the call to make a bigger announcement. Going forward, SpaceX will build its AI computing infrastructure exclusively on Nvidia chips. That means dropping AMD as a supplier entirely.

Why AMD Stock Fell After a Strong Quarter

AMD actually beat expectations that same day. Revenue climbed 50 percent to $11.5 billion. Earnings per share hit $1.66, ahead of estimates. Guidance for the next quarter came in above what Wall Street expected too.

None of that mattered once Musk's comments landed. AMD shares fell roughly 7 percent, driven by two separate concerns:

• Lost future business. SpaceX had previously said it would buy chips from both Nvidia and AMD. That plan is now off the table.

• Rising costs elsewhere. AMD's own capital spending doubled year over year, raising questions about how much profit its AI buildout is actually generating.

Musk kept the explanation simple. He called Nvidia's Vera Rubin architecture the best AI computing platform available. He added that SpaceX values its deepening partnership with the company.

What SpaceX Is Actually Building

The compute commitment is enormous by any measure:

• SpaceX plans to end 2026 with more than 2 gigawatts of AI computing power online.

• That figure could reach 15 to 20 gigawatts by the end of 2027.

• The company is targeting $100 billion in annualized revenue by December 2026.

• SpaceX has pulled forward its $1 trillion annual revenue target to 2029 or 2030.

Part of that buildout now extends into orbit. SpaceX confirmed it is joining Nvidia's "space computing" program. The project, called Starmind AI1, will place data centers inside satellites carrying Nvidia's newest Rubin GPUs. Separately, SpaceX has asked the FCC to approve up to 1 million orbital data-center satellites. That scale dwarfs the roughly 15,000 satellites orbiting Earth today.

How the Market Reacted

Nvidia shares rose about 3 percent Tuesday on the news. SpaceX stock initially jumped more than 9 percent. It then reversed and fell roughly 7 percent in after-hours trading as investors weighed the spending behind these targets.

Not everyone is convinced the bet pays off. Morningstar kept a one-star rating on SpaceX stock. Its fair value estimate implies more than 50 percent downside from current levels. The firm argues SpaceX's AI investments still outweigh its actual cloud rental income today. Other investors disagree. Cathie Wood's Ark Invest has been buying SpaceX shares as the stock trades below its IPO price, calling it one of her favorite holdings.

Why This Matters for Businesses Planning AI Budgets

This dispute captures something every business evaluating AI infrastructure should watch. Chip supplier concentration is rising, not falling. When one of Nvidia's largest customers publicly drops a competing supplier, it shows how much pricing power is held by whoever wins these exclusive deals.

Cynoteck covered a related dynamic in its report on Palantir's public criticism of frontier AI labs. The underlying question there was also about dependency: how much control does a business give up by relying heavily on one AI vendor's infrastructure? Businesses building AI strategy around a single chip supplier or cloud provider should treat that dependency as a real financial risk, not a footnote. Working through that risk with Cynoteck's Generative AI Services can help identify where a single point of dependency is quietly driving up costs.

Key Takeaways

• SpaceX reported $7.8 billion in Q2 revenue, up 92 percent, in its first earnings call as a public company.

• Elon Musk said SpaceX will build exclusively on Nvidia chips, dropping AMD as a supplier.

• AMD beat earnings estimates but still fell roughly 7 percent on the SpaceX news and rising CapEx.

• SpaceX is targeting 15 to 20 gigawatts of AI compute by 2027 and $1 trillion in revenue by 2029 or 2030.

• Analyst opinion is split, with Morningstar warning of overvaluation and Ark Invest buying the dip.

What Comes Next

Nvidia reports its own earnings on August 26, 2026. Analysts expect more detail then on how much of this demand is contracted versus aspirational. Businesses watching AI infrastructure costs should treat SpaceX's numbers as a signal of where chip demand is headed, not a guarantee of how it will play out.
