Elon Musk told Twitter employees that the company is now worth about $20 billion, less than half the amount he paid for it. The New York Times reported that Musk provided the $20 billion figure in an email sent to staff on Friday to announce a new stock compensation program.

"According to Mr. Musk's email about the new stock compensation program, Twitter employees will receive stock in X Corporation, the holding company he used to buy the company. Those awards will be granted under the $20 billion valuation. Mr. Musk also said in the email that he believed Twitter could someday be worth $250 billion," the NYT article said.
