Len Blavatnik, a Ukrainian-born billionaire and top donor to American neoconservative politicians, has purchased the most expensive home ever sold in the Hamptons for $115 million. The sale was finalized on July 31, 2025, and first reported by Behind The Hedges.
The property, situated in Amagansett on Long Island’s south shore, spans 8.5 acres and features waterfront access, a large outdoor pool, and a long, tree-lined driveway for added privacy. The mansion is situated on Further Lane, one of the most exclusive and expensive streets in the United States.

The previous owner, Terry Semel, former chairman and CEO of Yahoo and Warner Bros., purchased the estate in 2005 for $43 million from Blackstone founder Stephen A. Schwarzman. The property features a guesthouse that was originally a five-bedroom cottage, situated closer to the road than the main residence.
Blavatnik, who holds a majority stake in Warner Music Group, is ranked as the 59th richest person in the world by Forbes, with a net worth of $29.1 billion. His wealth stems largely from investments in a Russian oil company and his acquisition of Warner Music Group in 2011, which he later took public in 2020.
He is known for giving large political donations to politicians such as Lindsey Graham, Mitt Romney, John McCain, Kamala Harris, Hillary Clinton, Mitch McConnell, and Joe Biden. He also donated $1M to an anti-Trump PAC in 2016.
