The art market, for anyone who reads the room before the sale

Every collector I know reads the auction results the way bankers read interest rates. Not because we sell, but because the results tell us what everyone else is thinking.

This autumn the message is louder than it has been for two years. Let me explain why, with the numbers.

London, 14 October

During Frieze week, Christie's London held two evening sales on the same night. Together they made £218.6 million, about US$289.4 million, more than double the same sales last year, as reported by ARTnews. All prices include buyer's premium.

The first sale was the collection of Peter Simon, the founder of the British retailer Monsoon. It made £107.5 million, the highest value single owner collection ever sold at Christie's London. 41 works, only one unsold.

The top lot of the night came in the second sale: Wassily Kandinsky's "Das bunte Leben", which sold for £31.56 million on a hammer of £27 million, against a high estimate of £25 million. A Mondrian, "Composition III" of 1920, sold for £25.2 million.

There were seven auction records, including Liubov Popova at £7.64 million, more than three times her high estimate, and Bridget Riley at £5.21 million. Combined sell through was 91 percent by lot and 96 percent by value.

The fine print I always read

A good result can hide a lot. In the Simon sale, 29 of the 41 lots carried third party guarantees, which means much of the risk was placed before the first bid. Philip Hoffman, of the Fine Art Group, told ARTnews these auctions are "staged, managed, and already pumped up to the max".

He is right. A guarantee is not a lie, but it is not a crowd either. The second sale ended at 85 percent sold by lot, and works by Twombly, Giacometti and Freud went unsold. That is the real temperature.

New York, next week

Christie's New York sales begin on 17 November. The two biggest houses are expecting around US$1.1 billion at Sotheby's and more than US$800 million at Christie's, according to the pre sale estimates reported in the trade press.

At the centre is Sotheby's Blaquier Arrieta sale on 18 November, with a van Gogh estimated around US$180 million and Cézanne's "Arlequin" around US$120 million. If those numbers hold, it will be one of the great weeks of the decade.

For perspective, last May the three major houses sold more than US$2.5 billion in New York, with Pollock's "Number 7A" at US$181.8 million. The top of the market never really left. It was the middle that suffered.

Curious facts

• Das bunte Leben was restituted in 2023 to the heirs of Hedwig Lewenstein Weyermann. Restitution cases are now a significant source of masterpieces on the market.
• A third party guarantee means an outside investor promises to buy the work at a set price, in exchange for a fee or a share of the upside. It is finance, dressed for the evening.
• In London, the auctioneer Adrien Meyer called the Kandinsky the most important early work by the artist ever to come to auction.

The Portugal angle

Portugal plays in a different league, but it reads the same signals. In Lisbon, Cabral Moncada and Veritas are where Portuguese modern art changes hands, and I wrote this week about Almada at Cabral Moncada. In June 2026, Veritas sold Amadeo de Souza Cardoso's "Copo branco belleza dos objectos" for €476,340, and the Portuguese State then exercised its right of pre emption so the painting will go to the Museu Nacional Soares dos Reis, in Porto.

When London and New York are strong, Portuguese collectors feel richer and bid with more confidence at home. I have watched that happen for ten years.

My take

The market is healthy at the top and selective everywhere else. Masterpieces with fresh provenance sell, sometimes far above estimate. Everything that is merely good, or that has been seen too often, struggles.

I find that reassuring. It means people are buying with their eyes again, not only with their spreadsheets.

For anyone who reads the room before the sale, the room is telling us one thing: quality is back in charge.
