Vuong, the chairman of the Vingroup conglomerate, witnessed a staggering $2.3 billion surge in his wealth on a single day, marking the fourth-largest gain globally according to Forbes. This impressive increase eclipsed even the monumental $6.8 billion gain recorded by tech mogul Elon Musk, and the $4.3 billion gain of Oracle chief technology officer Larry Ellison.

Michael Dell, CEO of Dell Technologies, and Meta CEO Mark Zuckerberg rounded out the top five, adding $3.4 billion and $2.1 billion respectively to their fortunes. At the time of reporting, Musk retained his title as the world's wealthiest individual with an estimated net worth of $872 billion, while Vuong secured the 60th spot globally with $36.5 billion in assets.

The wealth gain was determined by fluctuations in the share prices of the billionaires' affiliated companies. Vingroup's shares hit an all-time high of VND236,000 ($9.05) on Thursday, marking a remarkable 38% growth since the start of the year. Notably, Vingroup was recently included in the FTSE Global Equity Index Series alongside 26 other Vietnamese companies.

On the same day, Vuong's wife, Pham Thu Huong, ascended to become the second wealthiest person in Vietnam, sharing the title with Nguyen Thi Phuong Thao, chairwoman of the low-cost airline Vietjet Air, each with a net worth of $4 billion.
