Sotheby’s 2 largest franchises are now company-owned 

Sotheby's International Realty, Inc. announced on Wednesday that it has acquired the brokerage's two largest franchises by sales volume: ONE Sotheby's International Realty and TTR Sotheby's International Realty.

Sotheby's President and CEO Philip White said the acquisitions mark "a strategic investment" in the strength of the Sotheby's brand and its people.

"ONE Sotheby's International Realty and TTR Sotheby's International Realty have built high-performing businesses grounded in strong leadership, deep market expertise and an unwavering commitment to their clients," White said in a statement.

The move makes the formerly independently-owned firms company-owned, strengthening Sotheby's company-owned operations in key luxury markets.

Acquisition adds major East Coast players: ONE Sotheby's was founded in 2008 and is based primarily along Florida's east coast, though it also expanded into New Jersey earlier this year. The firm closed $6.85 billion in sales across over 5,200 transaction sides in 2025, according to T3 Sixty's Mega 1000 brokerage rankings. The company has about 1,400 real estate advisors, according to its website.

TTR Sotheby's, which is based in the greater Washington, D.C., metro area, had a sales volume of $5.71 billion in 2025 across over 4,200 transaction sides, according to the Mega 1000. The firm launched in 1988 and has about 600 agents.

Existing leadership to stay: The current leadership teams at both ONE Sotheby's and TTR Sotheby's will remain in place, according to a news release.

Mayi de la Vega, ONE Sotheby's executive chair, and Daniel de la Vega, the firm's president and CEO, will thus stay with the firm. Meanwhile, Mark Lowham will remain executive chair of TTR Sotheby's, while David DeSantis and Derrick Swaak will retain their positions as CEO and president, respectively. The trio of TTR Sotheby's executives stepped into their current roles in late 2025.

TTR Sotheby's Founders Jonathan Taylor and Michael Rankin will also continue to have leadership roles at the brokerage, a press representative said.

Daniel de la Vega said the move will strengthen the company's foundation with direct access to the international brand's "world-class tools" and network "without compromising the boutique feel, agility, and hyper-local expertise that define who we are."

Building on de la Vega's comments, Lowham added that through the acquisition, "we're elevating what's possible in luxury real estate."

Part of Compass International Holdings' market share goal? The move by Sotheby's is the second in a recent string of acquisitions of some of the company's biggest franchises.

In July, the brokerage announced that it was acquiring Majestic Realty Collective, which encompasses eight Sotheby's subsidiaries: LIV Sotheby's International Realty, Summit Sotheby's International Realty, Sierra Sotheby's International Realty, Las Vegas Sotheby's International Realty, Sun Valley Sotheby's International Realty, Group One Sotheby's International Realty, Desert Sotheby's International Realty and Central Coast Sotheby's International Realty.

Now that the former Anywhere brands operate beneath Compass International Holdings' umbrella, the series of acquisitions could be part of Chairman and CEO Robert Reffkin's 30/30 vision — a goal to capture 30% market share in each of Compass' top 30 markets by 2030 — that he outlined during an October 2024 earnings call.

During that call, Reffkin said the company aspired to grow its listings in cities where it has the largest presence, which he said would thus enable the firm to achieve double-digit growth in gross transaction volume. Reffkin has not appeared to address this goal publicly anytime recently and declined to comment on it during a Q3 2025 earnings call.
