Brooklyn Nets owner Mikhail Prokhorov is tied with three others as the 69th-richest person in the world with a net worth of $13 billion, according to a Forbes Magazine list. Last year, Prokhorov ranked 58th.
Prokhorov, 47, is the second-wealthiest owner in the NBA behind Paul Allen of the Portland Trail Blazers (tied 53rd, $15 billion).
Prokhorov purchased the Nets for $200 million three years ago, and moved the team from New Jersey to the $1 billion Barclays Center prior to the start of the 2012-13 season.
When Prokhorov comes into New York to watch the Nets, he typically stays at the 52nd-floor penthouse suite atop the Four Seasons hotel in midtown Manhattan, which runs for $35,000 a night and has nine rooms, according to Forbes.
Prokhorov has political aspirations: He ran for president of his native Russia -- and lost -- in 2012.
"I have handed off all of my active business assets to my partners to manage," he told Forbes for this month's cover story, "so that 100 percent of my time is devoted to politics."
Prokhorov called the Nets his "passion project."
