Jay-Z's investments have made him the world's first billionaire rapper, with a net worth of $1 billion, according to Forbes.
Jay-Z, 49, pocketed approximately $500 million from his 14 No. 1 albums before taxes, but a large portion of his wealth comes from his business ventures, according to Forbes. He founded a clothing line that he sold to Iconix for $204 million in 2007 and co-owns cognac brand D'Ussé, in addition to owning music streaming service Tidal.
Jay-Z bought Tidal for $56 million in 2015. In 2017, Sprint bought a 33% stake in the company for $200 million, which put the company's valuation at $600 million. Jay-Z's stake in the company is now worth $100 million, according to Forbes.

Media mogul Oprah Winfrey is worth $2.6 billion, according to Forbes.
Born to a single mother in rural Mississippi, Winfrey started out as a news anchor before spending 25 years hosting "The Oprah Winfrey Show." The investments Winfrey made with her share of the show's profits are now worth about $2 billion, Forbes estimates. She became a billionaire in 2003, according to the Los Angeles Times.
Winfrey, now 65, also leveraged her show's success to build a media empire and amassed a fortune of $2.6 billion in the process, according to Forbes. She owns 25.5% of her television network OWN, an 8% stake in WW International, and has a content creation deal with Apple TV+.
Oprah has also voiced characters in "Charlotte's Web," "The Bee Movie," and "The Princess and the Frog," in addition to starring in "Lee Daniels' The Butler" and "Selma," among others, according to The Oprah Magazine.
Three-time Academy Award-winning director Steven Spielberg is worth $3.7 billion, according to Forbes.
The box office success of "Jaws," "E.T. the Extra-Terrestrial," and "Jurassic Park," among others, have made Spielberg the top-grossing director of all time.
According to Forbes, most of Spielberg's fortune comes from his films, but he has also profited from his role as a consultant for Universal theme parks and the sale of DreamWorks Animation to NBCUniversal for $3.8 billion in 2016.
Spielberg, 72, co-founded DreamWorks Pictures alongside Jeffrey Katzenberg and David Geffen.
George Lucas, the creator of the "Star Wars" and "Indiana Jones" franchises, is worth $6.3 billion, according to Forbes.
Lucas, 75, may be the brains behind two of the most well-known film franchises of our time, but he made most of his money by selling his production studio Lucasfilm to Disney for $4.05 billion in cash and stock in 2012, according to Bloomberg.
Lucas also executive produced "The Land Before Time" and wrote "American Graffiti," according to IMDB. His biggest-grossing film, "Star Wars: Episode I - The Phantom Menace," brought in $474 million at the box office.
While Lucas originally aspired to be a racecar driver, he decided to pursue filmmaking after nearly dying in a car crash. Lucas studied filmmaking at USC before founding Lucasfilm, according to the university's website. Lucas retired from his studio in 2012 in order to turn his attention to independent films, according to The New York Times.
