Elon Musk is one of the most successful entrepreneurs in the world and has been the richest person on Earth for a significant stretch of time. However, recently his wealth has decreased due to changes in Tesla’s stock price. This has allowed Amazon founder Jeff Bezos to surpass him as the richest person on Earth. But Forbes estimates that by 2023, Musk will reclaim the title as the world’s richest person, with his net worth expected to exceed that of Bezos once again

This raises the question of how long Musk will be able to keep the title of the world’s richest person. To answer this question, one has to consider the various factors that affect his wealth. First and foremost, his net worth is heavily dependent on the performance of Tesla’s stock price. As a major shareholder of the company, Musk stands to gain significantly if the Tesla stock price rises. On the other hand, any drop in the stock value could lead to a drop in his net worth.

Apart from the Tesla stock price, Musk’s other business ventures are also likely to play a role in his continued wealth. SpaceX, Musk’s aerospace engineering company, had a record year in 2020 and its successes could lead to further growth in Musk’s wealth. Additionally, his other companies such as Neuralink, The Boring Company, and SolarCity could add to his wealth in the near future.

Finally, Musk’s personal lifestyle should also be taken into consideration. While he is not known for splurging, he has invested heavily in luxury real estate and cars which could take a significant cut into his wealth if he chooses to continue such spending habits.

In conclusion, while Elon Musk looks set to again become the world’s richest person by 2023, the sustainability of this position can only be determined by a combination of factors such as Tesla’s stock price, the performance of his other business ventures, and his own personal spending habits.
