Christie's reported $4.7 billion in total sales for 2025, up 18% year-over-year, while Sotheby's posted $3.7 billion, a 14% gain, marking the strongest combined finish for the two houses since 2022. Private sales—transactions conducted outside public auctions—accounted for $2.1 billion of Christie's volume, nearly triple the $760 million recorded in 2024. Sotheby's private sales rose to $1.3 billion, up from $580 million the prior year.
The rebound came from two channels. Trophy lots—single works exceeding $20 million—generated $1.9 billion across both houses, with 47 pieces crossing that threshold compared to 29 in 2024. Luxury goods, a category encompassing watches, jewelry, handbags, and wine, contributed $1.6 billion, up 22%, as younger collectors under 45 increased their bidding activity by 31% according to internal house data. Buyer premiums—the surcharge added to hammer prices—averaged 24.8% at Christie's and 23.6% at Sotheby's, the highest rates since 2014, compressing net returns for sellers but inflating gross reported figures.
This performance reflects two structural shifts. First, ultra-high-net-worth individuals—defined as those holding liquid assets above $30 million—increased art and collectibles allocations by an estimated 340 basis points in 2025, per Knight Frank's Wealth Report. Second, private sales now function as a parallel market, with guarantees and financing terms unavailable in public auctions. Christie's extended $420 million in collector financing during the year, while Sotheby's reported $380 million, enabling buyers to lever acquisitions against other holdings. Both houses also expanded regional presences, with Christie's opening dedicated private sales offices in Hong Kong, Dubai, and São Paulo, while Sotheby's increased staff in Singapore and Mumbai by 40%.
The concentration risk remains visible. The top 12 lots accounted for $1.1 billion of total sales, meaning 13% of volume came from 0.08% of transactions. If trophy-lot velocity slows—as it did in 2023 when only 19 pieces cleared $20 million—the houses face margin compression, as luxury goods carry lower premiums. Additionally, private sales lack price transparency, making it difficult to assess whether reported figures reflect genuine market depth or channel-switching by houses eager to show growth.
Watch for Q1 2026 Impressionist and Contemporary evening sales in New York, scheduled for mid-May, which will test whether trophy-lot momentum persists. Also monitor whether private sales volume continues at this pace or reverts to the 15-18% of total sales seen in prior cycles. Finally, track buyer premium adjustments—if houses reduce surcharges to attract consignors, reported gross sales will diverge further from net proceeds.
The figure that matters is not the $8.4 billion headline. It is the $2.1 billion in private sales at Christie's, which now equals 45% of their auction volume and carries no regulatory reporting requirement.
The takeaway
Private sales at $3.4B combined now rival public auction volume, shifting price discovery into opaque channels with levered buyer structures.

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. Imprint manufacturing & Komori heritage press through approved vendors · Canon high-speed secure-media operations is a craft floor — genuine Six Sigma discipline applied to ink, thread, foil, and registration, where a hundredth of an inch is the difference between a brand that reads serious and one that reads cheap.

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.
