Where Is Ken Griffin Living in 2025? A Look at His Homes Across the Globe
Kenneth C. Griffin is the founder and CEO of the global alternative investment firm, Citadel and the founder of Citadel Securities. As such, he is a colossal figure in finance and ultra-luxury real estate. In early 2025, Griffin’s net worth may range from $40-$45 billion. He can afford to buy not just a house but massive estates, major record-setting penthouses, and historic mansions no matter where they are. His real estate portfolio is worth far more than a billion dollars, which raises the question of where Ken Griffin lives in 2025 with many different pieces of property to consider.
The Florida Pivot: A Strategic Relocation
In June 2022, Ken Griffin made an announcement that sent shockwaves through the financial industry: Citadel and Citadel Securities would be leaving Chicago and relocating their global headquarters to Miami. This was more than a corporate move; Griffin made Florida their primary home. He listed several factors including the energy and diversity of Miami, as well as its pro-business policies, as features that will attract talent. He contrasted this with issues Chicago has faced, including crime and population loss.
Miami: Epicenter of Operations and Living
Griffin is committed to Miami in a much more profound way than simply changing his mailing address. It takes form in brick-and-mortar investment options that are changing Miami’s skyline and creating the foundation for the financial city Miami is expected to become, often called “Wall Street South.”
Citadel’s Future Home: The most dramatic embodiment of this kind of commitment is Citadel’s planned headquarters tower at 1201 Brickell Bay Drive. Griffin has engaged the famed architecture firm Foster & Partners to create what Griffin calls “an iconic building in the world.” In 2024, Griffin filed plans for a stunning 54-story glass tower over 1,000 feet tall. It will include approximately 1.2 million square feet of office space, a luxury hotel, top restaurants, retail shops, public access to the waterfront that connects to the Baywalk, and a comprehensive set of climate-resiliency measures, designing and constructing seawalls, flood-proof doors, and any other applicable storm protections in response to climate change. Construction costs are expected to exceed $1 billion and could begin as early as late 2025 or 2026. While this tower is being developed, Citadel operates from temporary headquarters, initially at the Southeast Financial Center and moving into significant space at 830 Brickell, Miami’s newest office tower, where the firm expects to house hundreds of employees.
Residential Footprint – Miami: Griffin’s personal real estate acquisitions in Miami underscore his deep roots in the city. He embarked on a significant buying spree, notably assembling a vast waterfront estate on the exclusive, guard-gated Star Island. Through several transactions starting around 2020, he acquired approximately 6.5 acres of property for a combined total reported between $157.5 million and $169 million. While he later sold one of these properties to former baseball star Alex Rodriguez, the remaining assemblage represents one of the largest private holdings on the island.
Further south from the sailboats and cruising yachts, in 2022, Griffin purchased one of the most stunning waterfront estates from Adrienne Arsht, philanthropist and businesswoman, located in Coconut Grove, for $106.9 million— a record sale at the time. The estate encompassed two residences totaling approximately 25,000 square feet and 12 bedrooms. At the time, it marked his most significant buy on a single residence in Florida other than Palm Beach. Substantially, in March 2025, reports surfaced that Griffin listed a penthouse at the One Thousand Museum tower designed by Zaha Hadid for $23 million. Griffin acquired the unfinished unit quietly through an LLC in 2021 for $18 million. The fact that the penthouse is now listed could suggest that Griffin reorganized his portfolio to combine living offers in Miami, spanning his larger estates on Star Island and Coconut Grove.
Palm Beach: Crafting a Generational Estate
While Miami serves as the operational hub, Palm Beach is the stage for arguably Griffin’s most ambitious residential project—a breathtaking estate years in the making on the stretch of South Ocean Boulevard known as “Billionaire’s Row.” This isn’t just a mansion; it’s the creation of a legacy property.
The Assemblage: Starting back in December 2012, Griffin began methodically acquiring adjacent properties. Over a decade, he spent an estimated $500 million piecing together roughly ten separate parcels, including oceanfront lots and properties across the road on the Intracoastal Waterway. The result is a colossal domain of approximately 25 acres, believed to be the largest single residential landholding in Palm Beach, located less than a quarter mile south of Donald Trump’s Mar-a-Lago. Many of the existing homes on these lots were razed to make way for his singular vision.
The Vision: The centerpiece, currently under construction at 60 Blossom Way, is a sprawling 50,000 square-foot, single-story contemporary compound designed initially for his mother, Catherine Gratz Griffin, and intended eventually as his own retirement home. The plans, crafted by prominent architectural firms Olson Kundig and Smith and Moore Architects with landscaping by Stoev Design Group, depict a main residence and guest house occupying about eight acres. Features include vast glass windows for ocean views, multiple pools (including one running vertically to the main house), extensive gardens, patios, water features, pergolas, and a service basement. On a separate 2.6-acre Intracoastal lot across the street, acquired from the estate of Terry Allen Kramer, Griffin received approval to build a private tennis court and dock. The estimated construction cost runs from $150 million to $400 million, leading industry watchers to predict the completed estate could be worth a staggering $1 billion, potentially making it one of the most expensive private homes on Earth. Griffin’s investment here extends to environmental stewardship, as he is reportedly funding the replacement of groins (coastal structures that prevent beach erosion) in front of the property.
New York: Maintaining a Billionaire’s Perch
Although the move to Florida was emphatic, Ken Griffin continues to act as a giant in the Manhattan real estate market, owning several of the so-called elite addresses in the city.
220 Central Park South: Griffin hit the international headlines again in 2019, purchasing the penthouse at 220 Central Park South, a limestone tower by Robert A.M. Stern, then stepping into the most incredible heights of U.S. luxury penthouse history, buying it off the market at $238 million (just below the original asking price of $250 million), shattering the previous record of highest priced home ever sold in the U.S at the time. The penthouse is a quadplex of about 23,000 square feet between the 50th and 53rd floors, with a clear view of Central Park.
740 Park Avenue: In February 2025, Griffin acquired a duplex-coop apartment at 740 Park Avenue and continued his penchant to spend money on luxurious landmark real estate in New York even after his Florida relocation. This property was purchased in 2004 for 45 million dollars by Julia Koch, the widow of industrialist David Koch, and this deal put Griffin and his houses in the group of the notoriously exclusive, most popular, and historic residential properties in Manhattan. The purchase shows that New York is still an important place for Griffin to stay whenever he’s on business or personal trips.
London: A Transatlantic Anchor
Ken Griffin has also gained a prime slice of London real estate. Griffin owns 3 Carlton Gardens, a property in the St. James Plane of London acquired in January 2019 (before the record New York penthouse sale) for 95 million British pounds (about 122 million dollars then). It is no ordinary house; it is a spectacular Grade II-listed Georgian mansion of more than 16,000 square feet on the cusp of Buckingham Palace. The villa was once a wartime home to Charles de Gaulle and has been vastly upgraded since then. At the time of Griffin’s purchase, there was an indoor pool and large staff quarters. It was the most expensive purchase London home at the time. Having such exclusive real estate gives Griffin a strong foundation in one of the top financial centers in the world, where Citadel also holds a significant stake.
The Chicago Chapter Closes
As Griffin’s presence in Florida, New York, and London solidifies, his ties to his former home base of Chicago appear to be strategically lessened, particularly in real estate. He famously made record-setting purchases in Chicago, including spending $58.75 million in 2017 for multiple floors at the ultra-luxury No. 9 Walton condominium building. However, recent reports indicate a divestment. An April 2025 article mentioned Griffin selling two floors in that same building for $15.9 million, incurring a significant loss on that portion. This sale, coupled with his public comments about Citadel’s Chicago office being “hollowed out” as personnel relocated primarily to Miami and New York, strongly suggests a deliberate winding down of his residential footprint in the city that once served as his headquarters for decades.
The Bottom Line
Although he holds keys to mind-boggling estates in New York City and London and may also own other vacation destinations, the facts prove that South Florida has been his home base and epicenter.
His migration to Florida in 2022, in addition to the strategic relocation of the headquarters location of Citadel to Miami, followed by his enormous investment in the commercial and residential real estate of Miami and Palm Beach, consolidates Florida as his home base. He is based in Miami, building its new future there, and creating one of the most important private houses in the world in Palm Beach.
