Christie's reported $6.2 billion in total sales for 2025, Sotheby's $7.2 billion, marking year-over-year increases of 8% and 11% respectively after two years of mid-single-digit declines. The rebound came not from broader market depth but from a structural pivot: private sales now represent 34% of Christie's volume and 38% of Sotheby's, up from 22% and 25% in 2023.
Public auction totals remained flat. Christie's evening sales in New York, London, and Hong Kong generated $4.1 billion, essentially unchanged from 2024's $4.0 billion. Sotheby's evening sessions totaled $4.5 billion against $4.6 billion the prior year. The delta came from accelerated private treaty work—direct client-to-client transactions brokered off the auction floor—and from luxury goods verticals. Watches, jewelry, and handbags contributed $1.8 billion at Christie's and $2.1 billion at Sotheby's, growth rates of 19% and 23%. Modigliani's *Nu Couché* sold privately through Christie's in July for $139 million, never appearing at public hammer. Sotheby's closed a private sale of a Basquiat estate lot for $97 million in October.
The shift reflects client preference for discretion and pricing certainty. Public auctions carry reputational risk when lots pass or sell below estimate. Private deals allow sellers to lock in floors without public burn-in, and they spare buyers the theater of paddle competition. Both houses now staff dedicated private sales teams across 12 offices, up from 7 in 2022. Commission structures remain opaque, but market participants report blended rates of 18-22% on private deals versus the standard 25% buyer's premium at evening auctions. For houses, the math works: lower headline rates offset by reduced overhead, no guarantee exposure, and faster inventory turn.
Luxury adjacencies provided the other revenue leg. Christie's expanded its watch department to 47 specialists globally, Sotheby's to 41. Both houses now operate year-round online luxury sales with rolling close dates, capturing secondary-market churn that previously flowed to Chrono24 or 1stDibs. Hermès Birkin sell-through rates at both houses exceeded 96% in Q4, with median hammer prices 41% above 2024 levels. The handbag category, once a novelty vertical, now generates quarterly revenue comparable to Old Masters.
Allocators tracking wealth concentration should note the bifurcation. The number of lots selling above $10 million rose 14% year-over-year; lots selling between $500,000 and $2 million fell 9%. Mid-market softness persists. Buyers at the top remain active, underpinned by continued wealth creation in tech and finance. The $139 million Modigliani moved within 11 days of being offered privately; a comparable $1.2 million Impressionist work took 140 days to clear via consignment.
Watch for Q1 2026 evening sale catalogs, due for release mid-February. Consignment pipelines typically lag sentiment by 90-120 days. If private sales continue to cannibalize public hammer volume, expect both houses to formalize tiered client access—exclusive pre-auction viewings and first-look private offers for proven buyers. Sotheby's hired 23 client advisory professionals in Q4 2025; Christie's added 19. Those hires suggest the business model is settling.
The art market stabilized in 2025 not through broader participation but through controlled distribution. The top 200 collectors accounted for 47% of total spend across both houses, up from 38% in 2023. That concentration makes the market legible: a small number of proven counterparties transacting at known clearing prices, with the auction floor serving as occasional theater rather than primary venue. The houses that adapted fastest captured the liquidity.
The takeaway
Art market recovery in 2025 came from private deal velocity and luxury adjacencies, not auction floor breadth—72% of incremental revenue occurred off-hammer.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
Built by the craft floor — apparel, media, packaging, and secure print.
This trade runs on hands, not desks.

Beyond our own Virginia Beach floor, we work with a vetted network of craft manufacturers across the US — each meeting the highest excellence in QC standards in the industry, each a specialist in its own discipline — so apparel, hard-goods imprinting, media manufacturing, packaging, and secure printing all go to the bench built for them, coordinated from one accountable hub.
