SpaceX vs. Micron: Which High-Growth Titan Is the Better Buy?

The article compares SpaceX and Micron as high-growth trillion-dollar companies, weighing their growth, business quality, and valuation. Micron is growing much faster, with quarterly revenue up 346% year over year, benefiting from AI-driven memory chip shortages and strong pricing. However, its business is cyclical, and a future downturn could pressure margins and valuation. SpaceX is growing more slowly at 92% year over year, has no profits yet, but is viewed as more durable because its businesses span rockets, Starlink, X, and xAI with less cyclical risk. Despite SpaceX’s broader long-term business mix, the article concludes Micron is the better buy right now because its forward P/E is much cheaper than SpaceX’s price-to-sales valuation, and the memory shortage may persist beyond 2027.
