True dude always seemed like he knew what he was doing when it came to the business side of things. I got this from his Wikipedia so I don't know about how accurate it is, but he seems to be pretty charitable as well.
In 2001, Stephon donated $250,000 of the money derived from Pepsi sponsorships to help victims of September 11.
In 2005, Marbury donated between $500,000 and $1,000,000 to help victims of Hurricane Katrina.
In 2007, Stephon donated $4,000,000 to New York City, $1,000,000 each to the NYPD, FDNY, EMT, and New York City Teacher's Fund.
