Billionaires' Dream Retreats: Exploring the Most Expensive Islands in the World

The allure of private island ownership has captivated the world’s wealthiest individuals for decades. Beyond the luxury and seclusion, these acquisitions represent significant investments in real estate and lifestyle. A glance at recent transactions reveals fascinating patterns in how billionaires are reshaping island geography—and what drives their multimillion-dollar decisions. Let’s examine some of the most expensive islands in the world that have changed hands in the past decade.

Skorpios Island, Greece: The $150 Million Crown Jewel

When Russian billionaire Dmitry Rybolovlev’s daughter, Ekaterina Rybolovlev, set her sights on Skorpios Island in Greece, she wasn’t just purchasing real estate—she was acquiring history. This 74-acre private paradise, once the site of shipping magnate Aristotle Onassis’s wedding to Jackie Kennedy, commanded an eye-watering $150 million price tag. Her acquisition included the neighboring islet Sparti, making it one of the most expensive island purchases globally. Despite interest from other high-profile figures including Bill Gates, Giorgio Armani, and Madonna, it was Ekaterina who ultimately secured this piece of Mediterranean heritage.

Lanai, Hawaii: A Half-Billion-Dollar Development Vision

Oracle co-founder Larry Ellison’s $500 million acquisition of approximately 98% of Lanai represents more than personal indulgence—it reflects a strategic investment in island development. Spanning 141 square miles with nearly 50 miles of coastline, Lanai holds the distinction of being the largest privately held island in the United States. Rather than retreating into seclusion, Ellison has focused on infrastructure improvements and community development for the island’s 3,000+ residents. The Four Seasons resorts dotting the island demonstrate how luxury hospitality can coexist with genuine community investment.

Cayo Norte, Puerto Rico: Google Co-Founder’s Caribbean Playground

Larry Page, co-founder of Google, proved that tech billionaires have diverse investment portfolios when he acquired Cayo Norte in 2018 through an LLC called U.S. Virgin Island Properties. The $32 million purchase secured Puerto Rico’s largest privately-owned island, renowned for its pristine white-sand beaches, coral reef ecosystems, and wildlife sanctuary status—particularly for endangered sea turtles. The acquisition reflects a growing trend among billionaires: combining luxury with environmental consciousness.

Île Gagnon, Quebec: French Norman Elegance in Canada

Celine Dion’s private retreat on Île Gagnon in Quebec showcased a different vision of island luxury. Built in the style of a French Norman chateau and accessible via a private gated bridge, the property exuded European elegance transplanted to North American waters. When Dion decided to part with her island fantasy in 2016, the property sold for $25.5 million—testament to the enduring appeal of exclusive island residences.

Bonds Cay, Bahamas: When Artists Collaborate on Paradise

Shakira, alongside Pink Floyd’s Roger Waters and Spanish singer Alejandro Sanz, joined forces to purchase Bonds Cay for $16 million. Located 120 miles off Florida’s coast, this 700-acre island features five beaches and three salt pond lakes. The trio’s vision extends beyond personal use: they’re actively transforming the property into an eco-friendly luxury destination and artists’ retreat, suggesting that the most expensive islands in the world increasingly serve as platforms for creative and sustainable development rather than mere personal hideaways.

The Most Expensive Islands in the World: What the Trend Reveals

These acquisitions collectively demonstrate that modern billionaires view island ownership through a multifaceted lens. Beyond the price tags—ranging from $16 million to $500 million—lie deeper motivations: sustainable development, community engagement, artistic vision, and strategic investment. The most expensive islands in the world are no longer solely about escape; they’ve become laboratories for reimagining luxury, privacy, and purpose.
