His megayacht was too large to fit at his mansion, so Griffin built a private marina. Now, he wants a private helipad—but first he needs legal approval to change the city’s rules.
What You Need to Know
- Ken Griffin wants to build a private helipad on Terminal Island, Miami Beach, to connect his helicopter directly to the marina where his $250 million megayacht, Defy, will be docked.
- The project still relies on regulatory approval. The proposal will be reviewed by the Land Use Committee on September 16, and if approved, it will still require authorization from the FAA and the Florida Department of Transportation.
- Founder of Citadel, the 57-year-old Griffin has an estimated net worth of $51.7 billion and has donated about $2.4 billion to philanthropic causes.
Billionaire Ken Griffin, founder of Citadel, is preparing to reshape luxury transportation in Miami Beach. After securing unanimous approval from the city’s Planning Board to build a private megayacht marina, the hedge fund magnate is now turning his attention to the skies. His latest move is to add a private waterfront helipad to his sprawling multimillion-dollar development on Terminal Island.
The proposal is designed to create a fully integrated private transportation network by air, sea, and land, seamlessly connecting Griffin’s helicopter with his megayacht and properties across South Florida.
The $250 Million Megayacht That “Wouldn’t Fit at Home”
The project is driven by an unusual challenge: Ken Griffin’s megayacht is simply too large to be moored at his mansion. Although the billionaire invested $169 million acquiring residential properties on Star Island, his massive yacht is too large to dock at the property.
Named Defy (formerly Viva), the 308-foot (94-meter) superyacht is valued at approximately $250 million. Because the vessel already features a touch-and-go helicopter landing pad on its bow, the addition of a permanent helipad at the marina has always been part of Griffin’s original vision, allowing him to fly directly from elsewhere in Florida to his private marina.
The Ultra-Exclusive Project on Terminal Island
The private complex is being developed on a 30,000-square-foot (2,787-square-meter) waterfront property located at 120 MacArthur Causeway, part of a 3.5-acre (1.4-hectare) site Griffin purchased from Jorge Pérez’s Related Group, which had previously planned to develop an office complex there.
Plans for the site include:
- An exclusive building for the owner;
- A separate building dedicated to the yacht’s crew;
- Dedicated operations and maintenance facilities;
- Private security offices;
- At least one rooftop swimming pool.
The Industrial Zoning Strategy
To make a private helipad possible in Miami Beach, Griffin adopted a strategic approach: the selected property is located within a strictly industrial zone. Rather than attempting to operate aircraft near residential neighborhoods, the development sits next to ferry terminals, a Florida Power & Light (FPL) power plant, and a U.S. Coast Guard station.
The biggest challenge now involves changing the city’s development regulations. Private helipads are currently prohibited at the site. A proposal introduced on June 24 by Miami Beach Commissioner Joseph Magazine, and first reported by the Miami Herald, seeks to amend the zoning code to allow a helipad as an “accessory use” exclusively within the industrial area of Terminal Island.
The proposal will next be reviewed by the city’s Land Use and Sustainability Committee on September 16. Even if approved by Miami Beach officials, Griffin would still need authorization from the Federal Aviation Administration (FAA) and the Florida Department of Transportation. Facilities of this kind are exceptionally rare in Miami-Dade County, where most helipads are reserved for hospitals and emergency services.
Who Is Ken Griffin? Age, Net Worth, and the Success of Citadel
At 57, Ken Griffin has an estimated net worth of $51.7 billion. He founded Citadel in 1990, and the firm has grown into one of the world’s largest hedge funds. Today, it manages approximately $69 billion in investment capital and is recognized as the most profitable hedge fund in history, generating approximately $83 billion in net gains since its inception, according to LCH Investments.
Griffin also leads Citadel Securities, one of Wall Street’s largest market makers, responsible for processing approximately one out of every four U.S. stock trades. In recent years, he relocated both his personal residence and Citadel’s headquarters from New York to Miami.
Billions in Philanthropy
Beyond finance, Griffin is widely recognized for his philanthropic work, having donated approximately $2.4 billion to initiatives supporting healthcare, education, science, and the arts.
Among his most notable recent contributions are:
- $400 million to Memorial Sloan Kettering Cancer Center, alongside David Geffen;
- Tens of millions of dollars supporting healthcare institutions in Miami, including Sylvester Comprehensive Cancer Center, Baptist Health Miami Neuroscience Institute, and Nicklaus Children’s Hospital.
Political Views and Public Commentary
Beyond the financial world, Griffin has also been an active voice in public policy discussions. Although he has historically been one of the Republican Party’s largest donors, this year he publicly criticized aspects of the Trump administration, expressing concerns about decisions that he believed favored personal interests.
At the same time, Griffin praised measures such as strengthened border security and Kevin Warsh’s nomination to lead the Federal Reserve. Griffin argued that Warsh’s appointment would represent an important step toward preserving the central bank’s independence and strengthening confidence in the financial markets.
