No one has likely seen their personal net worth gain as much following Donald Trump's election win than Elon Musk. In just the first few days after Nov. 6, the billionaire entrepreneur saw his net worth exceed $300 billion for the first time since 2022 on the strength of gains made by Tesla (NASDAQ:TSLA) stock.

Musk has been so aggressive in pushing his views about Trump’s second term that he’s stepping on the toes of Trump’s transition team and may be overstaying his welcome at Mar-a-Lago, according to two people familiar with the transition who have spent time at the Palm Beach, Florida, resort over the past week.
