This isn't shaping up to be an especially good year for New York's ultra-rich. According to Forbes, Moscow recently overtook NYC as the city with the most billionaires per square mile: Moscow had 74 people worth ten figures compared to New York, which had just 71. But those smarmy bazillionaires aren't staying put in Moscow or even in the de-facto Russian mogul ghetto of London. Many of them are spending time right here in New York: Real estate, oil, and metals scions from Russia and other former Soviet republics have been busy snatching up some of the most expensive apartments the city has to offer. Last month, a 42-year-old fertilizer kingpin named Dmitry Rybolovlev agreed to pay $100 million for Donald Trump's Palm Beach mansion, Maison de l'Amitié. The 59th richest man in the world, worth some $12.8 billion, his purchase includes a 33,000-square-foot home and 6.5 acres of land. But he isn't the only one. After the jump, a list of the novi Russki who spend time in New York—just who these Soviet oligarchs are, how they made their money, and what exactly they're up to in town.
