Alexander Mamut is a Russian investor and former lawyer who built his fortune through deals in banking, retail, media, and entertainment. He started out in law, then moved into finance in 1990 by helping launch Business and Cooperation Bank and founding ALM-Consulting. During the 1990s and 2000s, he expanded through his A&NN investment company, with holdings that reached banks, insurance, mining, construction, and mobile phone retail.
His profile grew further as he moved into consumer and media businesses. He founded SUP Company in 2006, acquired LiveJournal Russia in 2007, and later became the owner of media assets tied to Rambler&Co, including lenta.ru and gazeta.ru. Outside Russia, he bought the British bookstore chain Waterstones in 2011. In 2017, he added Cinema Park and Formula Kino, two of Russia's biggest movie chains, and later sold Rambler to Sberbank in 2020.
How Alexander Mamut built his wealth
Mamut was trained as a lawyer, but most of his money came from investing. Over the years, he held stakes in banks, an insurance company, a fertilizer producer, and a mobile phone chain. His career included work in commercial banking early on, then a broader push through A&NN into retail, finance, and public-facing businesses. That mix gave him exposure to both traditional financial assets and companies with large customer bases.
Media and entertainment became another major lane. He founded SUP Company, bought LiveJournal Russia, and later controlled Rambler-linked media properties. He also owned Waterstones, the British bookstore chain founded by Tim Waterstone, which merged with Barnes & Noble in 2019. In film exhibition, he bought Cinema Park and Formula Kino in 2017. Forbes also notes that he later sold down Russian holdings and bought shares in American companies including Google and Apple.
Forbes net worth over time
Forbes estimated Alexander Mamut at $2.5 billion in 2019, then $2.3 billion in 2020 and 2021. The estimate moved to $2.1 billion in 2022 and $2 billion in 2023. Those shifts came during a period when his portfolio had changed shape, with earlier stakes across Russian finance, retail, media, and cinema, and with Rambler sold to Sberbank in 2020.
The decline continued to $1.2 billion in 2024, followed by $1.3 billion in 2025. Forbes' real-time billionaires tracker put him at $1.2 billion as of October 20, 2026. Forbes describes him as self-made and places him in Finance & Investments. The broad picture is a fortune built through investments, then reshaped over time by asset sales, ownership changes, and a move into shares of large American technology companies.
