In 2003, Kerimov managed to secure a $43 million loan from the state-owned Vnesheconombank, which he invested in the oil and gas company Gazprom. Within the next year, share prices for the Russian gas company doubled and Kerimov was able to pay off the entirety of the loan within four months. In 2004 Sberbank, now the largest bank in Russia and Eastern Europe, provided Kerimov with a loan of $3.2 billion., which was later repaid, and these funds were also invested in equities. By 2008, Kerimov had amassed a 5% stake in Gazprom, a 6% stake in Sberbank, along with an estimated fortune of $17.5 billion, making him the 36th richest man in the world. However, in mid-2008, Kerimov sold all his Gazprom and Sberbank shares.
