"Auction houses do not value art in the abstract. They value what they believe they can defend in a live market." In November 2025, Sotheby's New York totaled $1.17 billion. A Klimt portrait sold for $236.4 million, the second-highest auction price ever. Here is how auction houses value art.
Art auctions can feel like a closed world, but understanding how they work opens up real opportunities for buyers at every level. From Christie's to online bidding, this guide explains the process, the fees, and the strategy you need to bid with confidence.
Gallery directors are among the most influential figures in the art world, yet their work is largely invisible to outsiders. This guide explains what gallerists actually do, how they build careers for artists, and what a healthy gallery-artist relationship looks like.
On May 14, 2026, Christie's sold Jackson Pollock's Number 7A (1948) for $181.2 million at its New York evening sale. The painting came from the collection of publishing magnate S.I. Newhouse, and the sale was part of a $630.8 million single-owner collection that also included Constantin Brancusi's Danaide, which sold for $107.6 million. Two weeks earlier, Sotheby's had sold the Lewis Collection in London for $406.2 million, the highest-value sale of Impressionist, Modern, and contemporary art ever staged in Europe. By the end of June 2026, Christie's reported $4.5 billion in first-half revenue, its strongest opening six months in five years. Sotheby's reported a record $4.4 billion. After three years of declining sales and questions about the market's health, the auction houses were back, and the numbers were staggering.
An auction house is a company that facilitates the public sale of art, collectibles, and other valuable goods through competitive bidding. The auction house acts as an intermediary between sellers (consignors) and buyers, taking a commission from both sides. It authenticates, values, catalogs, markets, and displays the works before selling them at a public auction where registered bidders compete to offer the highest price. Christie's, Sotheby's, Phillips, and Heritage Auctions are the dominant auction houses in the art market, with Christie's and Sotheby's together controlling the majority of high-value fine art sales.
This entry covers what an auction house is, how the major houses developed, how auctions function within the art market, and what the 2026 data reveals about their current role.
The auction process begins with a consignment. A collector who wants to sell a work contacts the auction house, which sends a specialist to evaluate the piece. The specialist assesses authenticity, condition, provenance, and market value, and proposes an estimate, the price range the auction house expects the work to sell for. If the consignor agrees, the work is entered into an upcoming sale and assigned a lot number.
The auction house publishes a catalog with photographs, condition reports, provenance histories, and estimates for each lot. The catalog is distributed to the auction house's client list, which includes thousands of registered collectors, dealers, and advisors worldwide. Before the sale, the works are exhibited publicly, typically for three to five days, allowing prospective buyers to inspect the art in person. The exhibition is open to anyone, but bidding requires registration, which includes financial verification.
The sale itself is conducted by an auctioneer, who calls out lots in sequence, takes bids from the room, from telephone bidders, and from online platforms, and strikes the hammer when no higher bid is offered. The hammer price is the final bid. The buyer then pays a buyer's premium, a percentage added to the hammer price that typically ranges from 12% to 25% depending on the final price. The consignor pays a seller's commission, which is often negotiable for high-value lots and can be waived entirely for exceptional works. The auction house's revenue comes from the combination of buyer's premium and seller's commission.
Christie's was founded in London in 1766 by James Christie, who held his first auction on December 5 of that year. The early Christie's sold furniture, art, and decorative objects from estate sales, establishing the auction house as a venue for disposing of aristocratic collections. By the 19th century, Christie's was the leading auction house in London, handling major estate sales that dispersed the collections of British nobility.
Sotheby's was founded earlier, in 1744, by Samuel Baker, who specialized in book auctions. Baker's first sale was the library of Sir John Stanley, which sold for 826 pounds. The firm expanded into art and decorative objects in the 19th century under John Sotheby, Samuel Baker's nephew. The rivalry between Christie's and Sotheby's defined the London auction market for over two centuries, and both houses expanded internationally in the 20th century, opening offices and salerooms in New York, Hong Kong, Paris, Geneva, and other cities.
The modern art auction market took shape in the 1950s and 1960s, when the auction houses began selling Impressionist and Modern paintings at prices that rivaled the Old Master market. The 1958 Sotheby's London sale of the Jakob Goldschmidt collection, which included works by Cezanne, Van Gogh, and Renoir, was the first evening auction in London and is often cited as the moment the contemporary art auction was born. The sale lasted 21 minutes and realized $2.2 million, a staggering sum at the time.
The 1980s art boom transformed the auction houses. In 1987, Sotheby's sold Van Gogh's Sunflowers for $39.9 million, a record at the time. In 1990, Christie's sold Van Gogh's Portrait of Dr. Gachet for $82.5 million, a record that stood for over a decade. The prices established at auction became the benchmark for the entire art market, and the auction houses began to compete directly with commercial galleries for the best consignments.
The first half of 2026 marked a significant recovery for the auction houses. According to a report by ArtTactic released in July 2026, global auction sales at Christie's, Sotheby's, and Phillips were up 70% year-on-year, reaching $6.8 billion including fees. It was the best first-half performance since 2022. Christie's reported $3.5 billion in auction sales, up 71% from $2.1 billion in the first half of 2025. Sotheby's reported $2.8 billion, up 71% from $1.6 billion. Phillips reported $505.4 million, up 59% from $318 million.
The recovery was driven by major single-owner collections. Christie's was anchored by the S.I. Newhouse collection, which totaled $630.8 million in May. Sotheby's leaned on the Robert Mnuchin collection, the Lewis Collection, and other major estates. The pattern was clear: in 2026, great collections mattered more than great individual works. The ArtTactic report noted that while marquee evening sales were driven by $5 million-plus artworks from major single-owner collections, the strength of day sales demonstrated that confidence had also returned to the market's middle core. Sell-through rates reached 91% across the three houses, bolstered by 131 white-glove auctions, meaning sales where every lot sold.
What distinguished the 2026 recovery from previous boom cycles was the transformation of the auction houses' business models. An ARTnews analysis published in July 2026 noted that the houses devoted nearly as much space to private sales, lending, financial services, luxury goods, hospitality, and advisory work as they did to paintings and sculptures. Christie's reported over $1 billion in private sales in the first half of 2026. Sotheby's reported a record $826 million in private sales and completed a new $900 million securitization issuance, bundling art-backed loans into tradable notes for investors. The auction house was no longer just a place to sell art. It was a full-service financial institution for collectors.
Christie's is the world's largest auction house by sales. Founded in London and now headquartered in London and New York, Christie's operates salerooms in 10 cities and offers approximately 50,000 objects per year across more than 80 categories. In the first half of 2026, Christie's led the market with $4.5 billion in total revenue, a 91% sell-through rate, and 124% index of hammer price to low estimate. Christie's sold the top three works at auction in the first half of 2026: the Pollock at $181.2 million, the Brancusi at $107.6 million, and Mark Rothko's No. 15 (Two Greens and Red Stripe) from the collection of Agnes Gund at $98.4 million. Christie's reported that 47% of its new clients in the first half of 2026 were Millennial or Gen Z, and that online sales accounted for 63% of all new bidders and buyers.
Sotheby's, the oldest auction house, reported a record $4.4 billion in first-half 2026 revenue, including $3.4 billion in public auction sales and a record $826 million in private sales. Sotheby's reported a 90% sell-through rate by lot and an average of 4.9 bidders per lot, its highest in more than a decade. The house's $900 million securitization issuance in January 2026, the first to include loans secured against collectible cars as well as art, signaled the institutionalization of art-backed lending. Sotheby's has been privately owned since 2019, when it was acquired by Patrick Drahi for $3.7 billion.
Phillips, the third of the major houses, has positioned itself as the auction house for emerging and ultra-contemporary art. In the first half of 2026, Phillips reported $507 million in total sales, with auction sales up 59% year-on-year. Phillips has leaned heavily into watches and luxury collectibles while the ultra-contemporary art segment has cooled. A $96.3 million Geneva watch auction in May 2026 set 43 records. Phillips's average sale price of $78,500 per lot in the first half of 2026 was a fraction of Christie's $326,900 and Sotheby's $350,300, reflecting its focus on younger, lower-priced artists.
Heritage Auctions, based in Dallas, Texas, posted its highest mid-year total ever in 2026: $1.4 billion, up 47% from $962 million in the first half of 2025. Heritage specializes in collectibles and memorabilia, including comic books, sports memorabilia, coins, and vintage video games. Its growth reflects the broadening of the auction market beyond fine art into the wider collectibles economy.
The auction house is one of the two main sales channels in the art market, alongside the commercial gallery. The art fair is the gallery sector's equivalent of the auction, a concentrated selling event. The provenance of a work, its ownership history, is documented in auction catalogs and is a key factor in valuation. Appraisal is the professional valuation that precedes consignment. The Paris Salon was the historical precursor to the modern art market's public exhibition and sales system.

The major auction houses hold public exhibitions before every sale, and these exhibitions are free and open to anyone. You do not need to be a registered bidder to walk in and look at the art. The exhibitions are held in the auction houses' New York and London salerooms, typically for three to five days before the evening sale. This is one of the best ways to see major works by canonical artists up close, without paying museum admission.
If you want to see the auction itself, evening sales are open to the public on a first-come, first-served basis, though seating is limited. The atmosphere is unlike anything else in the art world: a packed room, banks of telephone operators taking bids from collectors around the world, an auctioneer calling prices in the hundreds of millions, and a hammer falling in seconds.
