SpaceX shares have reportedly fallen 20% below their initial public offering price, reversing part of the enthusiasm that followed the company’s record-setting market debut. The drop is said to have erased roughly $1.2 trillion in value, marking a sharp shift in sentiment around one of the market’s biggest new listings.

The company is described in the report as Elon Musk’s rocket, satellite and artificial intelligence business, a mix that had helped fuel excitement at launch. That early optimism appears to have cooled as investors pulled back from higher-risk technology names.

The selloff points to a broader change in appetite for speculative growth stocks. Even companies tied to major themes such as space, communications and AI can face heavy pressure when markets become more cautious.

While the trimmed report does not detail all of the drivers behind the decline, the headline move is clear: SpaceX’s post-debut trading has turned sharply lower, and the scale of the reported value loss underscores how quickly momentum can reverse after a blockbuster IPO.
