According to Forbes’ 2021 Billionaires List, the person with the most cash in the world is currently Elon Musk, with a net worth of $163.7 billion. Musk’s fortune has skyrocketed over the past year, primarily due to the meteoric rise of Tesla’s stock price. In addition to Tesla, Musk also has substantial investments in SpaceX, Neuralink, and other companies.

It’s worth noting that “cash” in the traditional sense of paper currency and coins is not the primary source of wealth for most of the world’s billionaires. Instead, their fortunes are largely tied up in the value of companies they own or have significant stakes in, as well as other assets such as real estate, artwork, and collectibles.
After Elon Musk, the next wealthiest individual on Forbes’ 2021 Billionaires List is Jeff Bezos, founder and former CEO of Amazon, with a net worth of $151 billion. Bezos still holds a significant stake in Amazon, which has continued to perform strongly during the COVID-19 pandemic due to increased demand for online shopping.
In third place on the Forbes list is Bernard Arnault, CEO of LVMH (Louis Vuitton Moët Hennessy), with a net worth of $150 billion. Arnault’s wealth is primarily tied up in LVMH, which owns a portfolio of luxury brands such as Louis Vuitton, Dior, and Fendi.
In fourth place is Bill Gates, co-founder of Microsoft and one of the world’s most well-known philanthropists, with a net worth of $124 billion. Gates has sold much of his stake in Microsoft but still owns a significant amount of the company’s shares.
In fifth place is Mark Zuckerberg, co-founder and CEO of Facebook, with a net worth of $97 billion. Zuckerberg’s wealth is primarily tied up in his ownership of Facebook, but he also has significant investments in other companies and ventures.
Other notable billionaires on the list include Warren Buffett, the “Oracle of Omaha” and chairman and CEO of Berkshire Hathaway, with a net worth of $96 billion; Larry Ellison, founder and former CEO of Oracle, with a net worth of $93 billion; Larry Page and Sergey Brin, co-founders of Google parent company Alphabet, with net worths of $91.5 billion and $89 billion, respectively; and Mukesh Ambani, chairman of Indian conglomerate Reliance Industries, with a net worth of $84.5 billion.
It’s worth noting that these net worth figures are based on estimates and may not necessarily reflect an individual’s actual liquid assets or cash holdings. The Forbes list takes into account the value of an individual’s assets, including shares of publicly traded companies, private equity holdings, real estate, art collections, and other assets.
In conclusion, as of my knowledge cutoff date of 2021-09, Elon Musk is the individual with the most cash in the world, according to Forbes’ 2021 Billionaires List. However, it’s important to note that the wealth of the world’s billionaires is primarily tied up in the value of companies they own or have significant stakes in, as well as other assets, rather than in traditional forms of cash.
