Ken Griffin and Goldman Properties Acquire Landmark 545 Wyn Office Building In Wywnood From Sterling Bay For $180 Million

Billionaire investor Ken Griffin has expanded his South Florida real estate presence with the acquisition of 545 Wyn, a premier office property in Miami’s Wynwood Arts District. Partnering with Goldman Properties, the duo purchased the 10-story building for approximately $180 million, signaling continued institutional confidence in Miami’s evolving office market. The deal reinforces Wynwood’s transition from a creative enclave into a fully formed mixed-use business district attracting global capital and blue-chip tenants.

Located at 545 Northwest 26th Street, 545 Wyn stands as one of the neighborhood’s most visible commercial assets. The transaction brings together complementary strengths: Griffin, founder of Citadel, provided the majority of the equity, while Goldman Properties will oversee management and long-term strategy for the building. The sellers were Sterling Bay, which developed the project in 2019 after acquiring the site from Goldman Properties years earlier—creating a full-circle moment for the Miami-based firm.

Developed by Sterling Bay, who broke ground on 545wyn in January 2019 and completed the building in late 2020, the 298,000 square feet of creative office and retail property offers future and current tenants access to large flexible floorplates and an unmatched suite of exclusive, highly sought-after healthy building amenities including a state-of-the-art wellness center, touchless elevator systems, vast outdoor lounges and high-quality air filtration systems. The building was designed by Gensler Architects and was Wynwood’s first-ever Class A office and retail property. To reflect the artistic aesthetic of Wynwood, Sterling Bay commissioned a number of creative installations at the property, including three very prominent exterior murals, to engage local and international artists and establish a sense of place for tenants. After recently achieving WELL Health-Safety Rating, 545wyn has also achieved RESET Air marking the property as one of the healthiest commercial buildings in Miami.

Spanning roughly 298,000 square feet of Class A office space along with more than 26,000 square feet of ground-floor retail, 545 Wyn has become a cornerstone of Wynwood’s commercial core. Its tenant mix reflects the area’s growing appeal to established corporations and forward-looking firms alike, including Sony Music Group, PwC, Gensler, cryptocurrency exchange Gemini, and crypto-backed mortgage lender Milo. This diversity underscores Wynwood’s ability to attract tenants across media, professional services, design, and financial technology.

For Griffin, the acquisition adds another strategic foothold in Miami, a city that has increasingly drawn high-net-worth individuals and major firms seeking business-friendly conditions and global connectivity. For Goldman Properties, long known for shaping Wynwood’s cultural and real estate identity, the partnership represents a continuation of its role in guiding the district’s next phase of maturation. Together, the acquisition of 545 Wyn highlights not only confidence in a single asset, but belief in Wynwood’s long-term position as a major office and mixed-use hub within Miami’s urban core.

Ken Griffin Revealed As Buyer Behind The Record Breaking $106 Million Deal For Adrienne Arsht's Bayfront Estate

When a residential sale crossed the $100 million threshold for the first time in Miami-Dade County history in August as The Arsht Estate sold for $106,875,000, many wondered who the mystery buyer was. It has been revealed that multi-billionaire hedge fund magnate Ken Griffin, who founded and recently moved Citadel Securities from Chicago to Miami, was the buyer in the mega-transaction for the four-acre waterfront compound which was formerly owned by Adrienne Arsht. Ashley Cusack with Berkshire Hathaway HomeServices EWM Realty represented Arsht and Jill Hertzberg of The Jills Zeder Group with Coldwell Banker represented the undisclosed buyer later revealed to be Griffin.

Neighbored by the historic Vizcaya Museum, The Arsht Estate encompasses more than 25,000 square feet of exquisitely detailed structures. Overlooking Biscayne Bay from atop one of Miami’s highest bayfront elevations, it features more than 400 feet of water frontage, as well as panoramic views of Key Biscayne and downtown Miami. Throughout the years, the property -- often referred to as South Florida’s “embassy” -- has been the backdrop for numerous important events and gatherings involving international luminaries, including U.S. presidents, ambassadors, and world leaders. The Arsht Estate features two connected estates, a primary residence, known as Indian Spring, which was built by Arsht in 1999 and designed by Jose A. Gelabert-Navia; as well as Villa Serena, which was built in 1913 by former U.S. Secretary of State and three-time U.S. presidential candidate William Jennings Bryan and is listed on the National Register of Historic Places.

After announcing earlier this year that both Citadel and Citadel securities will move to Miami from Chicago, Griffin has been on a buying and expansion spree. Citadel signed a lease for 95,000 SF at OKO Group’s 830 Brickell office tower. At roughly the same time, through an entity Griffin acquired the adjacent 1250 Brickell Bay Drive and 1260 Brickell Bay Drive for $20 million, the lots total roughly 6,655 SF. The lots are adjacent to 1221 Brickell Avenue, which an entity tied to Citadel reportedly acquired in June 2022 for $286.5 million.

Magic City Tech Boom? Microsoft In Negotiations At 830 Brickell And Elon Musk Wants To Build Tunnels Under Miami

Miami, the magic city, is on track to become the next Silicon Valley as the fallout from the COVID-19 pandemic has brought people flocking to South Florida. Florida saw the second highest population growth over any other state in 2020, following Texas, adding over 240,000 new residents in a single year. The influx of new residents is being driven by those looking to take advantage of remote-working opportunities or seek a state that has let business remain open and has pro-business tax structure. This has led to Miami and Palm Beach real estate pricing and absorption reaching near record highs.

Not only are the new residents flocking from the high-tax New York, at the same time as South Florida’s population boom, the San Francisco Bay Area has seen an exodus of venture capitalists and tech entrepreneurs. Mayor Francis Suarez has opened up the city to tech entrepreneurs and has expressed interest in bringing innovative companies to the magic city and making Miami a global tech hub. Mayor Suarez recently announced he will be appointing a Chief Technology Officer for the city.

Miami’s office market is being a surge in demand and setting record high pricing. Microsoft (NASDAQ: MSFT) is one of the major tech firms looking to move to Miami, the multinational software provider is actively in negotiations to lease 30,000 square feet of space at OKO Group’s 830 Brickell, a 56-story office tower adjacent to Brickell City Centre which is currently under construction. Pricing is still relatively cheap compared to other major markets, asking rates at 830 Brickell are reportedly in the $70’s PSF range. Ken Griffin’s Citadel Securities hedge fund is also reportedly looking at office space in 830 Brickell as is the Chicago-based law firm Baker McKenzie.

The biggest news came when Tesla and SpaceX founder Elon Musk tweeted that he had talked with Florida Governor Ron DeSantis about building a tunnel system underneath Miami to eliminate traffic and pollution. Mayor Suarez tweed that “we will do it,” and invited Musk to visit him at City Hall. In the past Miami has had success building tunnels at a comparatively low cost. The initiative would be led by Elon Musk’s Boring Company, who is getting ready to reveal the Vegas Loop to the public, a 4,475’ tunnel loop under the Las Vegas Convention Center. In the Las Vegas Loop passengers will reach speeds up to 155 mph and will ride in Tesla Model X’s, Model 3’s, and a 16-passenger modified Model 3. Las Vegas in now working with the Boring Company to build a citywide network of tunnels.
