According to the Bloomberg Billionaires Index, the Microsoft founder’s fortune is now $13.5 billion bigger than that of the world’s second-wealthiest person, the Spanish founder of the retailer Zara, who is worth an estimated $76 billion, according to Forbes. Wealth X, a wealth-tracking website in January had pegged Gates’ net worth at $87.4 billion; Forbes has him at $78.6 billion. Irrespective of this, Gates is constantly ranked the world’s richest man, and $90 billion is a new record. Gate’s friend and investor Warren Buffett also tops the lists on a regular basis. Earlier this month, the Oracle of Omaha was listed by Wealth X with a net worth of $65.7 billion. On the other hand, Billionaire Republican presidential nominee Donald Trump’s net worth is pegged at $4.5 billion. In 2010, Gates and Buffett started what’s called “The Giving Pledge,” a group of extremely wealthy individuals who have vowed to give away at least half of their wealth to charities. Some 154 billionaires around the world have joined the pledge, including Elon Musk, Sheryl Sandberg, and Larry Ellison since the launch of the initiative. Source:Bloomberg
