SpaceX shares fall premarket after Nvidia deal news, as Tesla-linked chip ambitions face fresh questions

SpaceX shares reportedly slid in premarket trading as a high-profile Nvidia-related arrangement raised questions among some market commentators about the direction of Elon Musk’s broader technology plans. The move follows renewed attention on whether an exclusive relationship involving Nvidia is a sign that SpaceX is recalibrating its strategy, rather than accelerating a route that had been seen as connected to Tesla’s chip ambitions.

The latest discussion, highlighted in a market-news post attributed to Yahoo Finance, also references commentary from Morningstar that focused on what Nvidia exclusivity could imply for Tesla-linked “Terafab” expectations. Morningstar’s concern, as described in the coverage, was whether the Nvidia deal indicates a retreat from plans previously framed around Terafab, a concept tied to Tesla’s efforts to secure a manufacturing and supply pathway for advanced semiconductors.

In the same report, Musk is said to have backed a very large “bull case” estimate of $10 trillion and responded publicly to critics. The coverage characterizes his comments as both supportive of the upside scenario and directed at “crowded shorts,” suggesting a confrontational tone toward investors positioned for downside.

For Tesla investors, the immediate relevance is indirect but potentially meaningful. SpaceX is not Tesla’s operating unit, but the software and hardware ecosystem around advanced computing, along with Musk’s continuing emphasis on vertical integration, tends to influence market narratives about the scalability of his approach to high-performance systems. When premarket trading moves in SpaceX coincide with headlines about chip supply chains and compute partnerships, Tesla’s semiconductor story often becomes part of the conversation.

The semiconductor and data-center hardware world is increasingly shaped by a small number of dominant suppliers. Nvidia has become central to AI compute deployments, and exclusive or preferential arrangements can tighten access to high-demand systems. That can create a strategic tradeoff for companies planning their own specialized chips or manufacturing stacks, because it may alter timelines for when teams can rely on in-house silicon versus established accelerators.

Still, important details were not disclosed in the headline framing that reached investors. The report does not provide a breakdown of contract terms, the duration of the Nvidia arrangement, whether it limits SpaceX from using alternative chips, or how any compute procurement plan might map to Tesla’s Terafab trajectory. Without those specifics, the market debate is necessarily focused on inference rather than on confirmed changes to engineering roadmaps or capital plans.

What to watch next is whether additional reporting clarifies the scope of the Nvidia deal, including whether it is exclusive across all workloads or just for certain product lines. Investors will also want further indicates on the status of Tesla’s semiconductor manufacturing plans that have been discussed as Terafab, including any updates from Tesla on timelines, capacity, or partnerships. If the Nvidia relationship expands or is described as a longer-term dependency, it could intensify scrutiny of whether bespoke chip ambitions are being slowed, or simply sequenced around the most urgent compute needs.

In the meantime, the main takeaway from Thursday’s coverage is that market participants are treating the Nvidia news as potentially consequential for Musk’s technology roadmap. The premarket slide in SpaceX stock, paired with public rebuttals from Musk and commentary from Morningstar, underscores how quickly AI supply chain headlines can translate into trading pressure, even when the underlying operational changes may not yet be fully specified.
