Leonid Mikhelson is the founder and chairman of natural gas producer Novatek. In 2017 he bought a 17% stake in petrochemical company Sibur from Kirill Shamalov, Putin's reported former son-in-law, increasing his stake to 48%; he now holds just over 30%. In 2021 Sibur merged with TAIF Group, with extensive assets in the Republic of Tatarstan; among TAIF's owners are the sons of Tatarstan's first president. Mikhelson spent more than $470 million turning a power plant across from the Kremlin into a spectacular art space GES-2, which opened in late 2021.
