The winner of the game show, Potanin's chosen "employee," will get an annual salary of 3 million roubles ($109,100), around 30 times the average annual wage but still some way off Potanin's own pay packet.
According to Forbes magazine, which last month published a list of the world's richest people, Potanin's empire of nickel mining, banking and property was worth $6.4 billion compared to the $2.6 billion of Trump.
However, in a new survey of the richest Russians published this week, Forbes bumped Potanin's wealth up to $7.6 billion, making him Russia's ninth richest person.
A former Soviet foreign trade official, Potanin served as deputy prime minister in the 1990s while building a portfolio, which ranges from media to metals.
Critics say he was a driving force behind the murky and speedy privatization of much of Russia's wealth under President Boris Yeltsin, in which a few well-placed "oligarchs" snapped up huge oil and mineral assets at a fraction of their true value.
Potanin and his partners paid a few hundred million dollars for control of the world's biggest nickel producer, Norilsk Nickel, which is now worth close to $22 billion.
Under President Vladimir Putin, he has stayed clear of politics, but adopts a high profile in the arts and philanthropy.
