Owner: John Malone
Estimated value: N/A
John Malone overtook Ted Turner as the biggest private land owner in the U.S. when he amassed 2.2 million acres in 2011. He now currently owns Sampson Cay, in the Exuma chain of islands in the Bahamas.
The 31-acre island is home to a resort and marina, which was rebuilt in 2002. The cost of staying at the resort can go up to $8,000 per week. Little information exists about when Malone - the Chairman of Liberty Media, which owns stakes in QVC, and Sirius XM Radio - bought the island. Still, the media tycoon is one of several famous names to buy islands in the Exuma Cays, a 365-island archipelago.
Other notable island owners include LVMH head Bernard Arnault, magician David Copperfield, and actor Johnny Depp, just to name a few.
