Shares in SpaceX fell 13.6% in a single trading session, wiping out roughly $120 billion in value, according to Motley Fool reporting on the move. The decline is notable because SpaceX trades in more limited, often private, markets, making a swing of this size unusual and hard to attribute to a single piece of news.

Analysts covering the stock have flagged a mix of good and bad signals heading into the drop. One Motley Fool piece pointed to artificial intelligence as both a 'green flag' for SpaceX's growth prospects and a 'red flag' for its rising costs, since AI infrastructure demand is pushing up the launch provider's own expenses even as it may expand its addressable market.

What remains unresolved is whether the drop reflects a one-off repricing of risk or a more durable reassessment of SpaceX's earnings trajectory. Investors awaiting the company's eventual public listing are also watching for volatility tied to lockup expirations, which Motley Fool coverage separately flagged as a source of turbulence for patient investors weighing an IPO entry point.
