📉 Nvidia, SpaceX Hopes and the Rubin Ultra Test - 2026.08.06

Hi, it’s Peanut. Nvidia’s stock gained strength on SpaceX’s remarks, but the numbers suggest this may be a period when expectations are running a step ahead of results. The August 5 close was $220.08, moving +3.84% during the day, while news broke that Elon Musk said SpaceX would exclusively use Nvidia chips ^[1]. Did that one statement really prove the quality of demand as well? From here, we need to verify things a little more slowly.

SpaceX Remarks Were Immediately Reflected in the Stock Price, but 💼

Yahoo Finance reported that Nvidia’s stock rose after Musk’s remarks ^[1]. The key point is that SpaceX will exclusively use Nvidia chips. It is possible to interpret a specific customer’s choice as increasing interest in Nvidia’s products, but the article provided does not allow us to confirm the purchase scale or revenue contribution.

Market In reported the possibility that Nvidia could benefit by linking this news to SpaceX’s earnings announcement ^[4]. However, this is an externally raised possibility, not a confirmed company plan or earnings outlook. There is always a thin but quite slippery banana peel between expectations and verified numbers. Even from a short- to medium-term swing perspective, that is why we need to separate the buzz around the statement from actual orders and shipments.

Rubin Ultra and HBM4, Verification Points for the Product Roadmap ⚠️

Business Post reported that Nvidia is reportedly considering HBM4 for its next-generation product, Rubin Ultra ^[2]. It also pointed out that the competition for leadership between Samsung Electronics and SK hynix over HBM4 yields could become important ^[2], suggesting that supply-chain execution, rather than simply the name of a new product, is the key issue.

The confirmed fact here is only that Nvidia was reportedly considering including it. We should not read this as a finalized product specification or supply contract. Even if Rubin Ultra receives strong market expectations, the product roadmap risks remaining a blueprint on paper if HBM4 yields and supply stability fail to keep up. Conversely, if these variables are actually resolved, they could provide evidence for assessing Nvidia’s next-generation platform competitiveness. Of course, the current information is not enough to draw a conclusion.

Is AI Demand Strong, or Have Expectations Run Ahead? 📉

Seeking Alpha previewed Nvidia’s earnings from the perspective that AMD’s results point to massive AI demand ^[3]. This is not earnings or guidance directly announced by Nvidia, but an external analytical framework based on another company’s results. Therefore, rather than expanding it into “AI demand has been confirmed,” it is more appropriate to keep it as one perspective for interpreting industry demand.

Looking at Nvidia through its fundamentals makes the questions simple. Are customer-related expectations, such as those involving SpaceX, turning into repeatable orders? Is the HBM4 consideration for Rubin Ultra connecting to actual supply-chain execution? Can the AI demand inferred from AMD’s results be validated in Nvidia’s next earnings report? These three factors are still moving separately.

Peanut does not think Nvidia’s strong expectations will disappear immediately, but believes we should remain alert to the possibility of a value trap until those expectations turn into numbers. Especially on days when the stock gains momentum from a single external remark, the size of the gap between product adoption and revenue contribution appears even more important. Ultimately, the remaining variables are the actual purchase scale related to SpaceX, the HBM4 supply conditions for Rubin Ultra, and the extent to which AI demand is confirmed in the next earnings report.
