SpaceX is reportedly considering a potential $1.5 trillion IPO, which would be the largest ever, surpassing Saudi Aramco. This follows a recent share sale valuing the company at approximately $800 billion. Investor interest is driven by SpaceX's launch dominance, Starlink expansion with over 3,000 satellites deployed, and potential future applications like space-based data centers, particularly amid the AI boom. While engineering challenges for space infrastructure exist, the company's repeatable execution fuels Wall Street's anticipation.
