American businessman Warren Buffett on Wednesday joined the closed circle of executives whose wealth exceeds $100 billion, which includes Jeff Bezos, Elon Musk, Bernard Arnault and Bill Gates, according to Forbes magazine.

On Wednesday, the share price of his company Berkshire Hathaway hit a record high, boosting his fortune to $100.3 billion

This is the first time that the company has taken this step.

Warren Buffett, 90, baptized the Oracle of Omaha , is one of the most successful and respected executives of all time, but his fortune had never reached such a peak, with investors betting on technology stocks in recent years.

According to Forbes, the Berkshire Hathaway conglomerate owns more than 60 companies, including U.S. insurer Geico and battery maker Duracell.

Warren Buffett is a generous donor, having given more than $41 billion to date, mostly to the Gates Foundation and his children's foundations, according to Forbes.

In 2010, he and Bill Gates launched the Giving Pledge, asking billionaires to commit to giving at least half of their wealth to charity.

According to Forbes' real-time ranking of billionaires, only four executives have a higher fortune: Amazon founder Jeff Bezos (179.6 billion) followed by Tesla boss Elon Musk (165.1 billion), LVMH group executive Bernard Arnault (158.5 billion) and Microsoft co-founder Bill Gates (125.6 billion).
