David Geffen is Hollywood's richest man. Here's how he spends his $8.5 billion fortune, from real estate in the Hamptons and California to his 453-foot superyacht that's hosted Jeff Bezos and the Obamas

Movie and music producer David Geffen is worth an estimated $8.49 billion, making him the richest man in Hollywood, according to Bloomberg's Billionaires Index.

The Brooklyn-born billionaire dropped out of college to join the entertainment industry, starting his career in the mailroom at William Morris Agency in Manhattan, where he worked his way up to being a talent manager.

In 1971, he founded music label Asylum Records, where he signed artists like Jackson Browne.

After about a year, Geffen sold the label to Warner Communications for $7 million and proceeded to serve as the head of the merged Elektra/Asylum Records.

In the 1970s, Geffen had a high-profile relationship with singer Cher.

Although Geffen later came out as gay, Cher said of the relationship in a 2012 interview: "At that point in his life, I was the right person for him."

In the 1980s, Geffen ran his music label, Geffen Records.

High-profile artists signed to the label included John Lennon and Yoko Ono, Elton John, Donna Summer, Guns N' Roses, Aerosmith, Don Henley, Cher, and Peter Gabriel.

Geffen later sold the label to MCA for $550 million worth of stock.

A few months after that deal, Geffen made $700 million when MCA was bought by Matsushita Electric Industrial Co., Ltd (which later became Panasonic), according to Bloomberg.

With the movie arm of his business, Geffen Pictures, Geffen produced films including "Risky Business," "Beetlejuice," and "Interview with a Vampire."

He also owned a Broadway theater company that produced shows such as "Cats" and "Dreamgirls."

In 1994, Geffen cofounded movie studio DreamWorks SKG with Steven Spielberg and Jeffrey Katzenberg.

He left DreamWorks in 2008.

The 76-year-old billionaire owns millions of dollars worth of real estate in California. His primary home is reported to be the sprawling Jack Warner Estate in Beverly Hills.

According to Variety, Geffen has lived at the Beverly Hills estate since 1990, when he bought it for $47.5 million.

The mansion is named for Jack Warner, the cofounder of Warner Bros, who built it in 1937.

The nine-acre property includes a 13,600-square-foot Georgian-style mansion, two guesthouses, a tennis court, swimming pool, nine-hole golf course, terraces and gardens, and a motor court with its own service garage and gas pump.

Geffen owns at least two other homes in Beverly Hills. In the spring of 2019, Geffen picked up a $4.65 million Beverly Hills house next door to one he already owned.

Geffen's new 3,267-square-foot home comes with four bedrooms and a swimming pool.

And the billionaire continues to pick up Beverly Hills properties. Just last month, Geffen paid $30 million — for an empty, one-acre lot.

The lot sits in the Trousdale Estates neighborhood of Beverly Hills known as "Billionaires' Row."

It's across the street from an extravagant mansion called "Opus" that was once listed for $100 million. The price has been cut to just under $60 million.

Until a couple of years ago, the billionaire also owned a beach house on Carbon Beach in Malibu, nicknamed "Billionaire's Beach" for the ultra-wealthy residents who have called it home.

Geffen's former property includes a main house, two guest homes, a pool and spa, gym, and a theater, as Business Insider's Tanza Loudenback previously reported.

He sold the beach house in an off-market deal for a reported $85 million in 2017.

Geffen has quite the real-estate footprint in New York as well. He's the owner of two condos, including a 12,000-square-foot triplex penthouse, in the Park Cinq, a luxury Fifth Avenue building near Central Park in Manhattan.

Geffen is the owner of the Park Cinq's 12,000-square-foot triplex penthouse, which he bought for $54 million from socialite Denise Rich in 2012.

A couple of years later, he paid $2.3 million for another unit in the building, a one-bedroom on a middle floor.

And until recently, he had owned a third apartment in the building, a two-bedroom unit that he bought for $14.17 million in 2010. That one he sold in May 2018 to a Russian-American oil billionaire for $24.5 million.

In the Hamptons, the ritzy vacation destination for New York's elite, Geffen owns a $70 million waterfront mansion.

He bought the property in April 2016.

About two months later, news broke that Geffen had sold another 5.5-acre Hamptons property that he'd bought in 2014 for about $50 million.

He sold it for $67.3 million.

The estate, which sits on coveted Georgica Pond, includes a seven-bedroom main house, an outdoor swimming pool, and a three-bedroom guesthouse.

Geffen is known for cruising the seas and hosting celebrity guests on his 453-foot superyacht, Rising Sun.

Geffen bought the yacht for $590 million from Oracle CEO Larry Ellison in 2010, according to Forbes.

His guests have included Barack and Michelle Obama, Oprah Winfrey, Bruce Springsteen, and Tom Hanks.

Most recently, Geffen was pictured partying on his yacht with Amazon CEO Jeff Bezos and Bezos' girlfriend, Lauren Sanchez, former Goldman Sachs CEO Lloyd Blankfein, and model Karlie Kloss and her husband, Josh Kushner, in the Balearic Islands in Spain.

In June, he posted photos to Instagram of his yacht adventures in Mallorca with stars including Chris Rock, Orlando Bloom, and Katy Perry.

Geffen reportedly had the yacht refitted over a six-month period.

The yacht, which can accommodate 18 guests and a staff of 55 people, comes with a double-height cinema and a basketball court.

But Rising Sun isn't the only superyacht Geffen has owned. In 2011, less than a year after buying Rising Sun, Geffen snapped up Pelorus, a 377-foot superyacht that he bought for $300 million from Russian billionaire Roman Abramovich.

The superyacht has two helicopter pads, a swimming pool with an artificial current, and a spa pool.

But Geffen didn't keep Pelorus for long. Later that year, he sold it to the Royal Family of Abu Dhabi for 214 million euros, or about $284 million at the time.

Geffen has donated hundreds of millions of dollars to educational institutions, museums, and gay-rights causes.

He established the David Geffen Foundation in 1986, which has focused its efforts on five main areas: populations affected by HIV/AIDS; civil liberties; the arts; issues of concern to the Jewish community; and health care.

After he donated $300 million to the University of California, Los Angeles, the university named its medical school after him.

It's now the David Geffen School of Medicine.

In 2017, Geffen pledged $150 million to the Los Angeles County Museum of Art.

It was the largest single cash gift from a single person in the museum's history, and the museum subsequently named its new building the David Geffen Galleries.

"It seemed as though, if I didn't do it, it wasn't going to get done — they've been attempting this for years and they couldn't raise the money," Geffen told The New York Times in an interview at the time. "I love art, I love L.A., and I could do it, so I did."

Geffen, who came out as gay at an AIDS charity event in the 1990s, has also donated to AIDS and gay-rights causes.

He's made contributions to organizations including Gay Men's Health Crisis, God's Love We Deliver, and the Elton John AIDS Foundation, according to The New York Times.

Geffen has an art collection worth more $2 billion, according to Bloomberg.

Bloomberg reports that Geffen has made "hundreds of millions of dollars" selling artwork by artists like Jackson Pollack, Jasper Johns, and David Hockney.

In 2006, Geffen sold two paintings by Jasper Johns and Willem de Kooning to hedge-fund billionaires Ken Griffin and Steve Cohen for a combined $143.5 million.

Ten years later, in 2016, Griffin bought another de Kooning painting and a Pollack painting from Geffen for $500 million total.

Geffen owned one of Hockney's famous pool scene paintings for about 12 years. He sold it to British billionaire Joe Lewis in 1995, who kept it for years before selling it at a Christie's auction for a record-breaking $90.3 million in 2018.
