Billionaires are increasingly buying up entire blocks or large swaths of land in South Florida to create massive private compounds, a trend exemplified by figures like Ken Griffin in Palm Beach and Paul Tudor Jones in West Palm Beach. This phenomenon, dubbed "billionaire Pac-Man," involves assembling multiple adjoining properties, often demolishing existing luxury homes, to achieve unparalleled privacy, control over surrounding views, and significantly larger estates than typically available. This strategy is especially prevalent in areas like Palm Beach, where undeveloped land is scarce, forcing the superrich to create new, larger properties by combining smaller ones.

For instance, Ken Griffin has amassed over 27 contiguous acres in Palm Beach, surpassing even Donald Trump's Mar-a-Lago in size. His plans include an approximately 50,000-square-foot home on eight of those acres, designed by Olson Kundig. Similarly, Paul Tudor Jones is working to acquire a portion of a public street in West Palm Beach to create a gated compound for two homes he is building, having already spent $9.87 million in 2021 for two waterfront parcels and another $6.4 million in 2023 for an adjoining property. This practice, while common in Palm Beach, is a newer trend in West Palm Beach, which is gaining a reputation as "Wall Street South."

The motivation behind these acquisitions extends beyond mere luxury; it's about establishing a "billionaire biosphere" where these individuals can control their environment. William P. Lauder, the Estée Lauder cosmetics heir, bought two oceanfront lots, demolished a six-year-old mansion on one, and later sold them as a pair for at least $165 million. Even in cases where they aren't building for themselves, billionaires are buying land to prevent others from building nearby, as seen with Larry Ellison and David MacNeil, who jointly spent $67 million on a 4-acre waterfront parcel in Manalapan to serve as a buffer between their estates. These purchases reflect a desire for rarity and an ability to "control the views, the noise levels, the privacy, the neighborhood."

Neighbors express concerns about these developments, especially regarding the closing of public access. For example, residents near Paul Tudor Jones's proposed West Palm Beach compound are worried about losing street parking and space for emergency vehicles. Despite these concerns, city planners often approve such requests, particularly when the applicant controls significant surrounding property, highlighting the influence of these wealthy buyers. The trend showcases a shift in high-end real estate, where the ultimate status symbol is no longer just a mansion, but an entire private domain crafted from multiple properties.
