Better Artificial Intelligence (AI) Stock to Buy: SpaceX vs. Nvidia - The Motley Fool

In the artificial intelligence (AI) investing landscape, investors now have a new option: Space Exploration Technologies (SpaceX). While not immediately obvious, SpaceX has entered the AI space throug... Read original →

SpaceX’s foray into AI via xAI reveals a critical gap: Grok relies entirely on third-party GPU clusters, lacking in-house AI silicon—unlike Nvidia’s vertically integrated stack spanning 3nm process nodes, EUV lithography, and Hopper architecture. This 'software-first, hardware-hollow' approach faces acute supply chain risk as U.S.-EU AI export controls tighten; any disruption to high-end GPU access would cripple model iteration. Nvidia, commanding over 95% of the AI training chip market, has cemented its moat through Grace Hopper superchips tightly coupled with cloud hyperscalers. Over the next 12–24 months, unless SpaceX develops its own accelerators or secures guaranteed wafer capacity—particularly from TSMC in Taiwan, China—its AI segment will remain trapped in low-margin ad revenue. The market’s 2.5x valuation premium over Nvidia reflects speculative diversification, not semiconductor-grade execution capability.
