Investor Michael Burry, best known for predicting the 2008 housing collapse, said Tuesday that he was tempted to bet against Elon Musk's SpaceX (NASDAQ:SPCX) but decided against it, citing expensive put options and questioned the company's $2.8 trillion valuation.

"I am not involved with SpaceX now.

Neither short nor, ahem, long," Burry said in a post on Substack.

Burry Reviews SpaceX Options Burry noted that a December 2028 put option with a $100 strike price was trading at about $25 while SpaceX shares were trading at around $212 at the time he wrote the post.

Burry added that the December 2026 put priced at $6.75 caught his attention, but he decided against placing the bet.
