Well currently, as of December 2021, his total net worth is totaled to around $266 billion. I believe, in my opinion, he will become a trillionaire within the next 10-20 years, that is unless Elon’s Tesla operation in China eventually bankrupts him. But considering his current net worth, and if he continues with SpaceX and other futuristic projects offering huge investments, 2030 could get him to around $500 billion.
