Gabe Newell, founder of Valve and the Steam platform, has purchased a roughly 20,000 square foot mansion in Manalapan, Florida for $70.8 million [1, 2]. The oceanfront estate includes a private tunnel that connects the property directly to the beach and ocean [1, 2].
The mansion boasts multiple luxury features such as an outdoor pool, a dock with a boat lift, a wine cellar, guest quarters, an eight-car garage, and a dedicated wellness wing [1, 3, 2]. Newell acquired the property from Cindy and Ron McMackin, who originally bought it for $39 million in 2020 [1, 2].
Newell, one of the richest figures in the video game industry with an estimated net worth of $11 billion, recently made headlines in May 2025 by purchasing a $500 million megayacht named Leviathan [1, 3, 2]. The yacht includes an onboard hospital, laboratory, spa, and gaming stations.
In a July 2025 interview, Newell detailed his daily routine on the yacht: "I get up, I work, I go scuba-diving, work some more, [then] either go on a second scuba dive or I go to the gym and work out. I live on a boat so I just hang out with everybody on the boat. Then I work" [2]. He also said, "I work seven days a week. I'm working from my bedroom, as you can tell. I like working. It's fun" [1].
The Florida mansion purchase marks a new chapter in Newell's lifestyle, combining his work with waterfront luxury. The private ocean tunnel is a standout feature, providing direct access to the beach from the estate.
The transaction comes six years after the McMackins first bought the mansion in 2020. Newell’s move to acquire such a high-end property follows his recent investment in the Leviathan yacht, signaling further expansion of his real estate and luxury holdings [1, 2].
