Apple CEO Tim Cook, Walmart CEO Doug McMillon, Disney CEO Bob Iger and OpenAI CEO Sam Altman were pictured entering the lodge.

Titans of tech and media are descending upon Sun Valley, Idaho, for the annual Allen & Co. conference nicknamed "summer camp for billionaires."

Bob Iger, the current Disney CEO, arrives at Sun Valley Lodge. Sun Valley is reportedly the location where the merger between ABC and Disney went down back in 1995. Then-CEO Michael Eisner—who is in attendance this year, too—met up with Capital Cities Chairman Thomas S. Murphy, according to the Los Angeles Times, and the rest was history.
