Larry Ellison has a casino once owned by Frank Sinatra.

Tech billionaire Larry Ellison recently purchased a Lake Tahoe resort once owned by Frank Sinatra for a tad under $36 million.

In the 1960s, it was a playground for celebrities like Marilyn Monroe and the Kennedy family. It's since lost its luster.

Not that the Oracle founder actually needed another home in the area. He already owns two multi-million-dollar homes nearby, as well as the entire Hawaiian island of Lanai, a historic garden villa in Japan, and the parcel of land that Nobu Malibu sits on.
