SpaceX went public at a $2 trillion-plus value, but the stock is already falling — bad news for regular buyers who got in at the top.

• The stock opened high and dropped through the day, so anyone who bought early is already losing money.
• Most of the value rests on hype around Musk and AI, not real profits — the company has negative revenue and no normal way to measure its worth.
• One analysis pegs fair value far below the trading price; the only profitable piece is Starlink, while space data centers and AI are unproven bets.
• Huge IPOs like this — with OpenAI and Anthropic expected to follow — often signal a market top, echoing the dot-com bubble and meme-stock craze.
• AI spending inflates profits in a way that can reverse fast: chipmakers book sales now while buyers spread the cost over years, so earnings can crash when orders stop.

Outlook: Expect more giant IPOs in 2026 and rising bubble risk, with SpaceX's price likely to stay shaky.
