Here’s a wild market moment: SpaceX is probably going higher. But before you FOMO into it, let me explain why that’s actually terrible news for most investors.
Last month, SpaceX went public in what Jeremy Grantham—a guy who’s been bearish since before it was cool—called “the craziest IPO in the history of man.” He’s not wrong. The company floated just 5% of its shares, yet somehow commands a market cap rivaling Amazon. That’s not a company; that’s a financial engineering masterpiece.
Here’s the kicker: SpaceX will probably keep climbing. But not because it’s a good investment. It’s because of math, not merit.
When SpaceX joined the Nasdaq-100 in July, index funds were forced to buy shares. That’s just the appetizer. The real feast comes this fall when lockups unwind in tiers, freeing up massive share tranches. As the float grows, so does SpaceX’s index weight—potentially hitting 4% by mid-August. Every percentage point increase forces another wave of automatic buying from funds with zero choice in the matter.
Even Grantham admits the price could climb “a lot” from here. Valuation? Irrelevant. It’s just plumbing.
But here’s what matters: SpaceX posted a $4.3 billion net loss in Q1 2026 alone. Its accumulated deficit since founding? $41.3 billion. The company carries $29.1 billion in long-term debt, including a $20 billion bridge loan. Meanwhile, its AI segment (xAI/Grok) hemorrhaged $6.4 billion last year while burning through billions more in capex.
S&P Global doesn’t expect positive free cash flow until 2029. Yet the stock trades at 70-90 times sales. For perspective, Nvidia—the actual profit-printing machine of the AI boom—trades at roughly 13 times sales.
The bulls will say, “Whoa, SpaceX is groundbreaking! Profits are coming!” Maybe. But “coming eventually” isn’t the same as “here now,” and the market’s pricing in a lot of faith.
The real lesson here: Know the difference between a stock rising on conviction and one rising on plumbing. SpaceX’s next leg up won’t reflect anything about SpaceX’s business. It’ll reflect index fund mechanics.
Meanwhile, the semiconductor space is getting hammered because SK Hynix’s IPO didn’t deliver the earnings pop investors expected. That’s creating real opportunities in names like Micron, which legendary investor Louis Navellier sees as a solid buy on the dip. Unlike SpaceX, Micron actually makes money.
The market’s sending a clear signal: there’s a difference between a company with a future and a stock with momentum. One builds wealth. The other builds heartbreak.
Watch for the SpaceX rally to get sold as vindication—proof the market “believes” in the company. That’s marketing, not analysis. The real story is simpler: funds have to buy it. That’s not a reason to join them.
