Dallas Mavericks owner Mark Cuban, who sued Barton publishing in April, is suing the publishing house for defamation and breach of contract, sources told ESPN.
Sources close to Cuban told ESPN that the Mavericks owner is seeking $5 million in damages for defamation, $2.5 million for breach of promise of future production of material, and $1.5 billion in punitive damages for “misrepresentation and breach,” sources said.
Cuban did not immediately respond to a request for comment.
Barton Publishing, based in New York, is best known for publishing music by hip-hop artist Drake, along with an award-winning sports column by ESPN’s John Hollinger.
Cuban said in a statement to ESPN on Friday that he will not comment on the lawsuit.
Barton has denied the allegations and said it is cooperating with the Mavericks’ investigation into Cuban’s allegations.
