Chief Keef net worth: Chief Keef is an American rapper who has a net worth is $1.5 million. Chief Keef, also known as Keith Cozart, was born in Chicago, Illinois. Chief Keef launched his rap career after getting arrested for aggravated unlawful use of a weapon, and being placed under house arrest. While under house arrest, he began posting YouTube videos of his own rap songs. The videos became massive hits, as did his subsequently released mixtapes and produced music videos. His mixtapes caught the attention of Kanye West, who helped him re-record one of his hit tracks called, "I Don't Like", with a number of popular artists, including Jadakiss and Big Sean. A new mixtape is in the works, tentatively titled, "Finally Rich", and featuring guest performances by such artists as Young Jeezy and Waka Flocka Flame. He is also slated to perform as part of Lollapalooza in 2012. Chief Keef has Asperger's Syndrome, which makes it difficult for him to interact socially. In June 2013, Chief Keef signed a potentially very lucrative contract with Interscope Records. The deal would cover three albums for Keef and could potentially be worth as much as $6 million. As part of the contract, Interscope paid Chief a $440,000 advance plus $300,000 to cover recording expenses to produce a commercial version of "Finally Rich". He also received a $180,000 advance for his record label Glory Boyz Entertainment and $200,000 to cover record label overhead expenses. There is also a stipulation that would allow Interscope to cancel the deal if "Finally Rich" did not sell 250,000 copies by December 2013. The album sold 150,000, but so far Interscope has not moved to drop Chief Keef's deal.
