1. Sheikh Khalifa Bin Zayed Al Nahyan, $18 billion
Sheikh Khalifa Bin Zayed Al Nahyan has an estimated personal net worth of around $18 billion. However, the Al Nahyan family may have a net worth around $150 billion plus. Sheikh Khalifa is the current Emir of Abu Dhabi and the president of the United Arab Emirates.
He has officially held presidential office since 2004 but was acting in a presidential capacity since the 1990s, when he was Crown Prince, due to his father’s poor health.
He runs the world’s second largest wealth fund, Abu Dhabi Investment Authority, which holds assets estimated at $773 billion. The world’s tallest building, the Burj Khalifa, is named after him.
