Valve co-founder Gabe Newell has bought a luxury estate in the coastal town of Manalapan, Fla., paying $70.8 million — a transaction that stood out in South Florida’s high-end real estate scene in 2026.
The parcel is about 2.06 ac and runs from the Atlantic Ocean to the Intracoastal Waterway. On-site: a mansion of roughly 20,000 sq ft (≈1,860 m²), an outdoor pool, a private dock with a boat lift, and an underground tunnel that opens straight onto the beach.
The sellers, Ron and Cindy McMackin (founders of Pan‑Pacific Mechanical), acquired the property for about $39M in 2020 and later put it on the market at $85M after moving into a larger nearby house.
Manalapan itself is tiny and intensely private — the sort of place that tends to attract ultra-wealthy buyers because of its unusually large oceanfront lots. This sale only amplified that reputation, drawing attention (and a few raised eyebrows) from people who follow the luxury market.
