The richest person in the world, Amazon founder Jeff Bezos, spent $65 million on a private jet.
Meanwhile, Tesla and SpaceX founder Elon Musk spent $70 million on his private aircraft.
Like many tech billionaires, Musk has also indulged in properties to build an impressive real-estate portfolio.
One of Elon Musk's residences — a $17 million Bel Air estate — includes a two-story library and a 1,000-bottle wine cellar. Other tech billionaires are also known for their impressive housing collections, including Michael Dell's "Castle" in Texas and Bill Gates's Xanadu 2.0 in Medina, Washington.
While Musk is known for typically driving one of his company’s more affordable cars, he did splurge on a submarine car that appeared in a James Bond movie.

Oracle founder Larry Ellison owns both a decommissioned Soviet MiG-29 and an Italian air force SIAI-Marchetti S.211.
Ellison is known for other extravagant purchases. He also owns a yacht-racing team — not to mention several of his own yachts.
Larry Ellison's current yacht is named Musashi, and is 288 feet long. He previously owned a much larger, 454-foot yacht named Rising Sun. Ellison reportedly sold the vessel for $300 million.
Additionally, Ellison owns one of the Hawaiian islands.
Microsoft's Bill Gates also owns a private jet, a purchase he has referred to as his “big splurge.”
Unlike Jeff Bezos' jet, which only seats eight, Bill Gates' $40 million plane reportedly seats 19 passengers.
Bill Gates also collects luxury sports cars.
Bill Gates' sports car collection, worth an estimated $650,000, includes a Jaguar XJ6 and a Ferrari 348. It also includes several Porsches — a Porsche 911, a Porsche Carrera Cabriolet 964, and a 1988 Porsche 959 Coupe.

Michael Dell, founder of Dell Technologies, and Rob Walton co-own a luxury hotel — the Four Seasons Resort Hualalai in Hawaii.
Purchased by Michael Dell and Walmart billionaire Rob Walton in 2006, the resort ranked No. 1 on US News & World Report's annual list of top hotels in the United States this year. The resort boasts seven swimming pools, luxury oceanfront villas that rent for $18,000 a night, and an impressive art collection. Dell also owns a Four Seasons penthouse in Boston in addition to his Austin home, known as "The Castle."
In addition to real estate, Dell spent $100 million on a private collection of photographs.
Gates, meanwhile, spent $36 million on a Winslow Homer painting and $30 million on a Leonardo da Vinci manuscript.
Both historic items are kept in Gates' Washington mansion, which is known as Xanadu 2.0. Gates purchased the Homer painting back in 1988, and bought the da Vinci manuscript six years later. Dating back to the 16th century, the valuable artifact is kept in his mansion's 2,100-square-foot library.
Mogul Richard Branson famously owns Necker Island, a purchase he made back in 1978.
Purchased for just $180,000, the British Virgin Island location's worth was estimated to be $60 million in 2006. Branson has also indulged in several expensive island toys — including a catamaran called the Necker Belle and a mini-submarine called the Necker Nymph — which he rents to guests staying at the resort. For this reason, Branson's indulgences are more often considered investments.
