Prince Alwaleed bin Talal al-Saud
Prince Alwaleed bin Talal al-Saud is so rich that he makes Trump and Abramovich look like amateurs. Seriously, the guy owns his own Airbus A380, which has been fitted with enough luxurious and security measures to make the Air Force One look obsolete. Keep in mind, a commercial A380 can fly as many as 800 people for over 8,000 miles without refueling, so you can just imagine how massive this guy’s private plane is.
In total, the Prince is said to have spent around $500 million modifying the jet to suit his needs, including adding a spot so he can park his Rolls Royce on the plane. He also owns an Airbus 321, Boeing 747, a whole fleet of smaller planes, and his very own 280ft SuperYachts, as well as a wide assortment of supercars.
TLDR; This guy is very rich.
