Is Mark Cuban Jewish?

Yes, Mark Cuban is a Jew. He owns the Dallas Mavericks NBA basketball team -- winners of the 2011 NBA championship.

Cuban's Russian Jewish grandparents changed the family name from Chopininski or Chabenisky when they immigrated to America. Cuban grew up in Mt. Lebanon, Pennsylvania, a suburb of Pittsburgh in a working class family.

In September 2002, Cuban married Tiffany Stewart, an advertising executive (who likely is not Jewish) in a private ceremony in Barbados.

The billionaire entrepreneur was charged in 2008 by the SEC with insider trading in what appeared to be a weak case.

Update: Case was dismissed but it can be refiled by the SEC (7/2009).

Update 2: Cuban is going after the SEC for malicious prosecution and has been granted discovery by the court (12/2009).
