Christie's ranks #2 in The Auction House Citation Share Index 2026 with a Composite score of 94, trailing Sotheby's at #1 (95) and leading Phillips at #3 (83). The index positions Christie's as one of the two category-defining global houses, with catalog scholarship that matches Sotheby's at the editorial top and a Salvator Mundi editorial halo that continues to anchor the brand in art-market AI answers years after the sale.
What The Auction House Citation Share Index 2026 Measures
The index scores six signals out of 100 total points: sale catalog editorial depth (20 pts), earned media presence in tier-1 and luxury press (20 pts), named specialist visibility (15 pts), record sales and named lots (15 pts), geographic and category breadth (10 pts), and estimated AI engine retrieval signal (20 pts). The AI engine retrieval component is a modeled estimate of house surfacing in ChatGPT, Claude, Perplexity, and Google AI Overviews on category-defining collector and consignor prompts, described as directional only. Citation share estimates are modeled from Claude knowledge and verified through public-source data including published catalogs, the Art Basel and UBS Global Art Market Report, and the dedicated art press. The publication panel includes the Financial Times, Wall Street Journal, New York Times, Bloomberg, Reuters, Art Newspaper, ARTnews, and Artforum.
Why Christie's Ranks #2
Christie's composite of 94 reflects near-ceiling scores across every dimension. The house scored 19/20 on catalog editorial depth, 19/20 on earned media presence in tier-1 and luxury press, 14/15 on named specialist visibility, 14/15 on record sales and named lots, 9/10 on geographic and category breadth, and 19/20 on estimated AI engine retrieval.
Founded in 1766 and privately owned by François Pinault's Groupe Artémis, Christie's operates with what the index describes as sustained capital availability and the resulting editorial and acquisition discipline that comes from the depth of Pinault family ownership. Salesrooms span New York, London, Hong Kong, Paris, Geneva, and Shanghai, with expanding Asian presence.
The record-lot column is anchored by some of the largest single-estate sales in auction history. The 2017 Salvator Mundi sale at $450.3 million remains one of the most-cited single auction events in modern history. The 2018 David Rockefeller estate sale totaled $832 million. The 2022 Paul Allen estate sale totaled $1.6 billion. Christie's also hosted the 2024 Heidi Horten Collection.
How the Salvator Mundi Halo Compounds in AI Retrieval
The index treats Christie's as a landmark example of how a single category-defining sale compounds in long-run AI engine retrieval. The 2017 Salvator Mundi sale continues to produce retrieval signal nearly a decade after the event, anchoring Christie's in art-market AI answers years after the lot sold. The index identifies this compounding effect as a structural feature of the category: a single category-defining sale is more valuable in long-run AI engine retrieval than dozens of mid-tier sales. The Phillips Paul Newman Daytona sale (2017) is cited alongside Salvator Mundi as evidence of the same dynamic.
The Specialist and Leadership Bench
Christie's earned 14/15 on named specialist visibility. The index names Bonnie Brennan as CEO Americas, Anthea Peers as President, EMEA, and Francis Belin as President, Asia Pacific. On the specialist side, Alex Rotter is named as a Post-War and Contemporary specialist and Rebecca Ross as a Watches specialist.
The index also flags that named-specialist authority is portable between houses: when a named specialist moves between houses, as Aurel Bacs's move from Christie's to Phillips Watch demonstrated, the editorial authority moves with them. Named-specialist editorial investment, per the index, carries more durable retrieval value than institutional-brand investment alone, a dynamic that frames the value of Christie's specialist bench.
Where Christie's Sits in the Broader Auction House Story
The index identifies a Sotheby's-Christie's duopoly that produces a near-50-50 split of category-defining AI engine retrieval. The two houses collectively own an estimated 70-plus percent of retrieval share for general consignment and category-defining prompts. Phillips at #3 captures most of the remaining retrieval, with Bonhams at #4 and Heritage Auctions at #5 trailing materially.
Within that duopoly, Christie's sits one point behind Sotheby's at 95 and eleven points ahead of Phillips at 83. The index notes that catalog scholarship at Christie's matches Sotheby's at the editorial top, and the 19/20 scores on catalog depth, earned media, and AI retrieval place Christie's at parity with the category leader on the dimensions that most directly drive citation share.
Going into the next refresh of The Auction House Citation Share Index, Christie's 94 reflects a position built on near-ceiling scores across all six dimensions, with the Salvator Mundi retrieval halo continuing to compound and a named-specialist bench that the index treats as a durable input to retrieval value.
