Opinion: Nvidia’s AI hardware edge over SpaceX’s Grok models
This opinion piece compares Nvidia and SpaceX as AI investments. Nvidia, valued at about $5.5 trillion, dominates AI hardware with GPUs like the Vera Rubin architecture, which SpaceX’s Elon Musk called the best AI computer. The new architecture promises a 10x cut in inference costs and 4x cut in training costs over Blackwell GPUs, reinforcing Nvidia’s lead in AI computing.
Key points
- Nvidia’s Vera Rubin GPUs cut AI training/inference costs by 10x/4x, per Elon Musk’s Q2 call
- SpaceX’s Grok model revenue grew 213% in Q2 but trails leaders like ChatGPT or Claude
- Nvidia’s $5.5T valuation vs. SpaceX’s $2T makes it the cheaper AI hardware play
SpaceX’s AI play is xAI, which owns the Grok model family. Grok’s revenue surged 213% in Q2, but it lacks the market share of leaders like ChatGPT or Claude. The piece argues Nvidia’s doubling revenue in Q2 and lower valuation (about $412B vs. SpaceX’s $45B) make it the safer, cheaper AI stock pick, despite SpaceX’s growth potential.
