Ken Griffin Miami Marina Project on Terminal Island

Billionaire investor Ken Griffin is expanding his South Florida empire with a private megayacht marina on Miami Beach’s Terminal Island. The project, designed by BMA Architects, will serve only Griffin and his guests. It will feature luxury amenities, modern design, and top-tier security.

A Private Waterfront Haven

Located at 120 MacArthur Causeway, the marina will span 30,000 square feet on 3.7 acres at the island’s eastern tip. The Miami Beach Planning Board is expected to vote on a conditional use permit at its November 4 meeting.

The design includes a gatehouse with security offices, a crew pavilion with laundry, gym, sauna, and rooftop pool, plus an operations center with offices and a repair shop. Additionally, the owner’s pavilion will feature a grand seating area, private storage, and a pool with sweeping bay views.

Moreover, a Citadel spokesperson emphasized Griffin’s commitment to Miami, stating, “Ken is investing to improve an industrial section of Terminal Island, reflecting his long-term dedication to the city.”

Expanding His Billion-Dollar Miami Portfolio

This new marina adds to Griffin’s vast South Florida real estate portfolio, which already surpasses $1 billion. In 2022, he moved Citadel and Citadel Securities headquarters from Chicago to Brickell, underscoring his belief in Miami’s long-term growth.

Furthermore, Griffin’s $2.5 billion Brickell supertall, currently in planning, will include 1.3 million square feet of office space, a 212-key hotel, a spa, and several fine dining restaurants. His move illustrates how Miami continues to attract global financial powerhouses.

At 56, Griffin also owns the 308-foot superyacht Viva, designed by Peter Marino. This vessel showcases his passion for design, craftsmanship, and the ocean lifestyle.

From Abandoned Office Site to Private Marina

The Terminal Island site has an intricate development history. It was previously owned by Related Group, which first proposed a condo tower and later an office building. However, both projects were abandoned. In 2023, Lincoln Property Company purchased the land for $77 million. Later that year, ownership transferred to an entity tied to Griffin.

Because the sale occurred through an entity transfer rather than a deed, the final price remains undisclosed. Today, Terminal Island hosts a Florida Power & Light plant, a Miami Beach maintenance yard, and ferry terminals that connect to Fisher Island, one of America’s wealthiest communities.

A Venue for Elite Global Events

According to the South Florida Business Journal, Griffin’s marina could host private gatherings during Art Basel and the Formula One Miami Grand Prix. These events would further enhance Miami Beach’s reputation as a luxury hub for art, culture, and entertainment.

Forbes ranks Griffin as the 32nd wealthiest person in the world, with an estimated net worth of $50.6 billion. His portfolio includes Adrienne Arsht’s $106.9 million Coconut Grove estate, multiple Star Island waterfront properties, and prime Palm Beach holdings.

A Lasting Symbol of Miami’s Future

Ultimately, the Ken Griffin Miami Beach megayacht marina is more than a private retreat—it is a symbol of Miami’s continued rise as a global capital of wealth and innovation. Through strategic investments and visionary projects, Griffin continues to anchor himself in South Florida’s evolving landscape.
