Elon Musk's net worth got a boost from Tesla's stock split.

Update: This article has been updated to reflect Teslas share price as of the market close on August 31, 2020.

Tesla stock soared Monday after a stock split, lifting Elon Musks net worth to $102.9 billion at the market close. Shares jumped 12.6%, boosting Musks net worth by $10.4 billion since late Friday. Forbes calculates that he is now the fifth centibillionaire in the world, as well as the fifth-richest person in the world.

Musks net worth has quadrupled since mid-March, when he ranked No. 31 on Forbes Worlds Billionaires list, with a net worth of $24.6 billion. Hes now just behind Facebooks Mark Zuckerberg, who is worth $107.6 billion.

Not that this matters to Musk. The 49-year-old serial entrepreneur said hes indifferent to his standing on the Forbes list of billionaires. I really couldnt care less, Musk emailed Forbes about his net worth in July. These numbers rise and fall, but what really matters is making great products that people love.

Musks fortune hit $99 billion on Thursday August 27, then dipped on Friday August 28 as the electric carmakers shares fell 3.6%. Tesla stock split on a 5-for-1 basis on Friday after the market closed and started trading on a split-adjusted basis Monday morning. Smaller traders have reportedly snapped up the lower-priced shares, which are now $498.32 versus Fridays $2,213.40.

Musk owns 21% of the $464 billion (market cap) company but has pledged more than half his stake as collateral for personal loans; Forbes applies a discount to his pledged shares to account for the loans.
