Denver billionaire Philip Anschutz has just become even wealthier—at least, his holding company has. Recent sales of oil and gas to an undisclosed buyer have reaped about $3 billion for Anschutz Exploration Corporation, notes the Denver Business Journal. An article in Forbes references the sale as “the biggest payday” of Anschutz’s lengthy career, which spans a realm of interests from railroads to energy to filmmaking.

While Anschutz is also the man behind the Examiner news organization, he personally shies away from press. Even Forbes couldn’t score an interview with Anschutz, but Anschutz Entertainment Group (AEG) CEO Tim Leiweke offers that his 70-year-old boss “has no ego. He is the anti-Donald Trump.” As Forbes writes, the thin, five-foot-eight-inch bike-racing man behind Southern Pacific, Qwest Communications, The Chronicles of Narnia films, and more, “has crowed publicly about none of them, earning him a reputation as one of the most secretive moguls in America.”
