Until March 2022 he headed Alfa-Bank, Russia's largest commercial bank. In March 2022, he resigned from the board of directors at Alfa-Bank and LetterOne Group amidst threat of sanctions. In 2023 he was named the 659th richest person in the world, with a net worth of around $4.2 billion. Aven is a member of Russian leader Vladimir Putin's inner circle.

Aven has met with Putin regularly, including soon after the Russian invasion in Ukraine. He is one of many Russian oligarchs named in the Countering America's Adversaries Through Sanctions Act, CAATSA. In 2022, Aven was included in EU sanctions imposed in the wake of the Russian invasion of Ukraine. He criticized the sanctions, alleging that they had been applied on a "spurious and unfounded basis," and filed a lawsuit in the European Court of Justice.
