Better Artificial Intelligence (AI) Stock to Buy: SpaceX vs. Nvidia

The article compares SpaceX and Nvidia as AI investment options. While SpaceX recently acquired xAI and owns the X social media platform, its AI division generated only $3.2 billion in revenue with 22% growth. Nvidia, by contrast, is growing at 85% year-over-year with 96% projected growth in the current quarter, generating over $250 billion in annual revenue. Despite SpaceX's $2 trillion market cap being 40% of Nvidia's $5 trillion valuation, SpaceX's 2025 revenue was less than $20 billion with $6.6 billion in adjusted EBITDA—far below expectations for its valuation. The author concludes Nvidia is the better AI stock choice due to more reasonable valuation and stronger AI business fundamentals.
