Two of the world’s wealthiest individuals are expanding their Manalapan waterfront compounds after purchasing portions of a neighbor’s 4-acre property for a combined $67 million, further consolidating the barrier island’s billionaire corridor and sending a signal about the enduring appeal of Palm Beach County’s ultra-luxury market.
Splitting the Parcel
Oracle co-founder Larry Ellison and WeatherTech founder David MacNeil acquired the land from Florida developer Stewart Satter, who had planned a record-setting $285 million megamansion on the site. That plan never materialized, and Satter is now dividing the property between his two neighbors. MacNeil paid $32 million for the northern portion, while Ellison will buy the southern half for $35 million in a deal expected to close within weeks, the Wall Street Journal reported. Nicholas Malinosky of Douglas Elliman represented Satter, and Margit Brandt of Premier Estate Properties represented MacNeil.
A Pattern of Expansion
Both billionaires have been active South Florida real estate buyers in recent years. Ellison paid $173 million for his Manalapan compound in 2022, acquired the Eau Palm Beach Resort & Spa in 2024, and purchased the 254-acre Lion Country Safari in Palm Beach County last year for $30 million. With a net worth of $238.8 billion, Ellison ranks as the fifth-richest person in the world, according to Forbes.
MacNeil purchased his 1.9-acre Manalapan property for $68.3 million in February and is set to buy another contiguous parcel for $36 million from car-dealership owner Ralph Gesualdo and his wife Mary. Once all purchases close, MacNeil will control approximately 5.5 acres on the barrier island. He has bought and sold more than $233 million in South Florida homes this year alone, including a $105 million Manalapan oceanfront assemblage in April — the most expensive land sale ever in the town — and a $26 million Fort Lauderdale mansion sold last month, per The Real Deal.
Market Context
The transactions underscore Manalapan’s status as one of the most exclusive waterfront markets in the country, where ocean-to-intracoastal parcels continue to command nine-figure sums as ultra-wealthy buyers compete for the limited inventory of buildable land along the barrier island. The transactions also reflect a broader trend of tech executives relocating primary residences to South Florida, drawn by favorable tax policies and waterfront lifestyle amenities that show no sign of losing their appeal despite broader economic uncertainty.
Brokers say the concentration of billionaire buyers in Manalapan has created a self-reinforcing cycle: as high-profile names accumulate property, the area becomes even more desirable to other ultra-wealthy individuals seeking privacy and exclusivity on South Florida’s waterfront.
