Space Exploration Technologies Corp.

(NASDAQ:SPCX) reported stronger-than-expected first quarterly financial results as a public company, prompting CEO Elon Musk to mock short sellers after bearish bets against the stock climbed to about one-third of its public float ahead of the earnings.

Musk Says Bears 'Double Down' Ahead of the earnings report on Tuesday, S3 Partners estimated that about 95% of SpaceX shares available to borrow had been lent out, with short interest reaching roughly 219.3 million shares, or about 34% of the public float, representing bearish bets worth approximately $24.6 billion.

"I try to warn them, but they just double down," Musk said in response to a post by Zerohedge that highlighted S3's data.
