SpaceX IPO: The Largest in Stock Market History - Should You Buy at a $1.8 Trillion Valuation?
SpaceX just made history, raising $75 billion in the largest IPO the stock market has ever seen, now trading on NASDAQ at a $1.8 trillion valuation. 7investing's Simon Erickson break downs what you actually need to know as an investor. The SpaceX empire spans X (formerly Twitter, 600M users), xAI (the Grok-powering AI infrastructure running out of the 2-gigawatt Colossus data center), and 10,000 Starlink satellites serving 10 million subscribers across 164 countries. The scale is genuinely unprecedented.But the numbers tell a more complicated story. SpaceX did $20 billion in revenue last year, pricing it at 90x trailing sales, and generated just $1 billion in Q1 operating cash flow against $10 billion in quarterly capital expenditures. The company is burning cash aggressively, and the entire long-term thesis rests on Elon Musk executing on missions no company has ever attempted: orbital data centers, Starship, and eventually a Mars colony. This isn't a software company where you flip a switch and double revenue. These are physical, capital-intensive bets measured in decades.Simon and Heather are both passing on the IPO. The key man risk alone, Elon simultaneously running SpaceX, Tesla (NASDAQ:TSLA), X, and xAI, is the largest concentration of founder dependency in stock market history. Tesla (NASDAQ:TSLA) fans know this playbook: extraordinary vision, breakthrough results, but timelines that consistently slip years past what Elon says publicly. Full self-driving still isn't there. Orbital data centers won't be either, at least not on the schedule the prospectus implies.Near term, Starlink is the real business the only one generating meaningful cash flow and it's what will sustain SpaceX while Elon bets big on everything else. Expect another capital raise in 2026 and again in 2027. The real question for investors isn't whether SpaceX can change the world. It probably will. The question is whether a $1.8 trillion valuation gives you any margin of safety while it gets there. Right now, Simon and Heather say no.Join the conversation on the 7investing discord: https://discord.com/invite/PT9ZQqdXXSWant access to all our investing content?
