Denver-based GD Holdings is tightening its already formidable grip on the St. Regis Chicago, snapping up a portfolio of 16 luxury condominiums from Sony in a bulk deal valued at $21 million, public records show.

The transaction, which breaks down to roughly $1.31 million per unit, underscores a recurring theme at the 101-story supertall: the power of the bulk discount.

Given the multi-million dollar figures individual units have recently commanded at the Jeanne Gang-designed tower, the pricing on the Sony deal, which includes penthouse units on the 89th and 77th floors, is notably low. While public records indicate the transaction closed last week and was for 100 percent of the interest in the properties involved, it remains unclear whether Sony will maintain a back-end stake in the financial performance of the units moving forward.

The 16 units GD just acquired have a unique backstory. Sony only recently gained control of the condos in January, receiving them from Chinese conglomerate Dalian Wanda Group, Chicago-based Magellan’s former joint venture development partner on the skyscraper. Wanda handed them off to settle a $49 million dispute with Sony over the intellectual property rights to kiddie cartoon “Octonauts.” While Sony was quick to flip its share to GD, Wanda still controls an additional 21 condos in the building. It’s unclear what Wanda’s long-term strategy is for those remaining high-end units as the developer continues to navigate its global real estate holdings.

With Sony’s speciality in entertainment rather than as a traditional real estate firm — one that already had to litigate against Wanda just to secure the 16 units in the first place — the seller likely had ample motivation to offload the portfolio quickly at a steep discount to its face value to extract cash and exit the investment.

Headed by denim magnate Salomon Juan Marcos Villarreal, GD Holdings has spent years building an elite selection of luxury real estate and hospitality assets across the country, including stakes at various points in Four Seasons hotels in both Denver and Nashville.

For GD Holdings, the acquisition is just the latest move in a broader strategy to consolidate the tower’s assets. The firm is already a massive stakeholder in the building. In late 2024, GD made its initial bulk condo purchase in the building of about 84 unsold units from its original developer, Magellan, for $117 million. Magellan CEO David Carlins declined to comment.

The Denver firm’s dominance extends well below the residential floors. GD Holdings is also a joint venture partner with Miami-based Gencom in the landlord group that owns the St. Regis hotel portion of the tower. That investment is proving lucrative; GD and Gencom boasted of the hotel’s performance as they snagged a fresh $125 million refinancing package last month. Gencom clarified that GD Holdings alone is the investor in the condo portion of the tower. A voicemail for GD Holdings executive Daniel Wolf wasn’t immediately returned Tuesday. Grupo Denim’s president Scott Steuer didn’t respond to an email requesting comment.

As for the units changing hands, GD Holdings is taking over a portfolio with immediate, top-tier income potential. According to a person familiar with sales at the property, the condos Sony sold to GD likely include at least a portion that are already fully built out and actively leased. The rental market at the St. Regis operates in the absolute stratosphere of Chicago real estate: penthouse units in the building are currently leasing for around $35,000 per month, while half-floor condo units are commanding roughly $25,000 a month.

With the hotel locked down, the 2024 Magellan bulk buy absorbing developer inventory, and this latest acquisition from Sony, GD Holdings has cemented itself as the captain of the St. Regis.
