Mikhail Prokhorov is the former chairman of a Russian gold producer.
== Lawsuit against Grigory Rodchenkov ==Following Russia's banning from the 2018 Winter Olympics and the stripping of medals from multiple Russian athletes, in February 2018, Prokorov agreed to finance a defamation lawsuit in New York against Grigory Rodchenkov, the former mastermind behind Russia's state sponsored Olympic doping program
 The deal has been singled out as a major success for Prokhorov as only three months later, following a dip in oil prices, a disastrous stock market crash halved the value of most Russian companies, including Norilsk
