The Globe and Mail reports in its Monday edition that few business leaders have been as deeply embedded in popular culture as Elon Musk, the ambitious entrepreneur who has become a central figure in Internet culture and amassed a fortune that has made him the world's first trillionaire. A Reuters dispatch to The Globe says at a time when concerns about inequality are high and public attitudes toward the ultrawealthy have soured, Mr. Musk has managed to retain a loyal following. While admirers view Mr. Musk's no-filter style as part of his appeal, critics have accused him of wielding oligarch-like power, raised concerns about governance at his companies and objected to his increasingly partisan political interventions. Mr. Musk's influence has become so pervasive that market observers have dubbed the network of businesses around him the "Muskonomy" and the "Elon premium," a valuation boost driven as much by faith in Mr. Musk's vision as by traditional financial metrics. "Much like Tesla, SpaceX is a bet on Elon Musk," said Matt Kennedy, senior strategist at Renaissance Capital. "A market cap of $1.5-trillion [to] $2-trillion would certainly throw all traditional valuation methodologies out the window," Mr. Kennedy said.
