The New Auction House: Where Luxury Rivals Fine Art

For the past year or so, I’ve been looking into how the traditional auction house model is increasingly leaning on selling things other than fine art. Much to the irritation of Sotheby’s et al., I’ve repeatedly asked what would happen if, for example, luxury sales like vintage designer clothing, watches, handbags and wine outstripped art sales. How might that reshape their identities, customer bases, and reputations?

It’s a valid question given the recent trajectory of the luxury sector. The category has become one of the fastest-growing parts of Christie’s and Sotheby’s businesses. Sotheby’s luxury sales hit $2.7 billion in 2025, more than triple its 2019 total. The same year, Christie’s luxury sales jumped 17 percent to $795 million, fuelled by demand for high-value goods that aren’t fine art.

Both houses released their H1 2026 results this week, offering a fresh look at how the auction game’s expansion into luxury, finance, and other collecting categories is reshaping their businesses. Sotheby’s reported record first-half consolidated sales of $4.4 billion, up 58 percent year over year, while Christie’s reported $4.5 billion, its strongest first half since 2021.

The wider auction market is fighting back hard. According to research from the London-based art market intelligence company ArtTactic, Christie’s, Sotheby’s, and Phillips generated $6.77 billion in combined auction sales during the first half of 2026, an almost 70 percent increase from the same period last year and the strongest first-half result since 2022. Single-owner collections generated $2.17 billion, accounting for 32 percent of total auction sales.

Landmark single-owner collections helped underpin Sotheby's results, attracting deep bidding and contributing to strong performance across all luxury categories. Auction sales reached $3.4 billion, up 59 percent year over year, while private sales reached a record $826 million. The company reported a 90 percent sell-through rate and a record 4.9 bidders per lot sold.

Fine art remained central to the performance. Sotheby’s New York marquee season generated a whopping $908.6 million with a 92.5 percent sell-through rate. The Robert Mnuchin Collection achieved $173 million, and the Lewis Collection in London reached $406.2 million, becoming the highest-value single-owner sale ever held in the UK.

Christie’s also benefited from exceptional collections. The S.I. Newhouse Collection generated $630.8 million, alongside major artist records for Jackson Pollock, Constantin Brâncuși and Mark Rothko. Sales of 20th- and 21st-century art rose 79 percent to $2.3 billion, supporting Christie’s strongest first-half performance in five years.

When I spoke with a Sotheby’s spokesperson yesterday about how luxury, lending, private sales, real estate and hospitality might influence the company’s future direction, they were particularly keen to move the conversation onto art sales. Sotheby’s is keen to manage its expanding identity; the company has built a much broader business around collecting but it is determined to present art as its core tenant.

“Our record first half was driven by broad-based strength and growth across our categories and regions,” a spokesperson for Sotheby’s said when I reached out to them with the questions. “From landmark single-owner collections continuing to come to market in both fine art and luxury, to our strength in financial services and demand for Sotheby’s Financial Services, our H1 results underscore the diversity of our business.”

That broader business is becoming increasingly visible in the results. Sotheby’s luxury division continued to grow during the first half, with sales from RM Sotheby, the wing of the auction house dedicated to collector cars, increasing 61 percent, watches rising 64 percent and jewelry climbing 13 percent. ArtTactic reported that Sotheby’s luxury auction sales reached $334 million during the period, up 28.1 percent year over year.

Luxury is also becoming an integral part of Sotheby’s strategy for reaching collectors across categories and regions. Hong Kong luxury auction sales rose 78.5 percent year over year, while the company continued expanding in the Middle East following its Saudi Arabia auction and Abu Dhabi Collectors’ Week, which generated $133.4 million across cars, watches, jewelry, handbags, and real estate.

Sotheby's Financial Services (SFS) adds another layer to that model. The division completed a $900 million securitisation—a financing transaction in which loans are bundled together and sold to investors—during the first half of the year. It has originated more than $12 billion in loans since its creation, extending the company’s relationship with collectors beyond the auction room.

The Breuer building in New York represents the physical side of this evolution. Sotheby’s headquarters now combines galleries, exhibitions, auctions, restaurants and cultural programming. The company reported that visitor numbers have more than doubled compared with its former York Avenue location since the opening of its new restaurant, called Marcel.

Christie’s has followed a similar path through private sales, luxury and art finance. Its first-half private sales exceeded $1 billion. Nearly half of its new buyers during the first half of the year came through luxury sales, according to the company.

With all of the above taken into account, it might only be a matter of time before art sales at the major auction houses are eclipsed by handbags, cars and other luxury items. This seems especially true at Sotheby’s. Even if the house doesn’t want to discuss it, its latest results show how far it has transformed into a broader collecting platform that encompasses not just art, but luxury, financial services and bespoke experiences that cater specifically to the needs of wealthy clients. And while the firm remains defined by exceptional art, its growth is increasingly coming from the opaque world that surrounds collecting.
