Yayoi Kusama died in a Tokyo hospital on August 14, aged 97, and the death was announced on August 27, as reported by NPR. Five weeks later Sotheby's, Christie's and Phillips held their autumn series in Hong Kong between September 28 and 30, with large Kusama canvases at the top of two of the three evening sales. It was the first auction week since her death with enough of her work on offer to say something, and the market had a story ready for it: the artist is gone, supply is now finite, prices go up.

They did not. The interesting part of the week is where the money went instead.

The pumpkins held, and that is all they did

At Christie's on September 29, Kusama's A-Pumpkin (YHP) (2011), a yellow pumpkin on an Infinity Net ground making its first appearance at auction, carried an estimate of HK$48 million to HK$68 million. It hammered at about $5.99 million, roughly 2% below the low estimate, as reported by ARTnews. The house's line afterwards was candid. "The artist's passing was priced in a long time ago because of her age, and we think this is a very respectable price with the buyer's premium, over $7 million," Christie's Ada Tsui told ARTnews.

The previous evening Sotheby's had sold a Kusama Pumpkin for HK$60.68 million with fees, about $7.8 million, as reported by Artdaily from the house's results. Two large pumpkins in two nights, both landing near the bottom of their ranges. The South China Morning Post's headline on the week put it plainly: the Kusama works got "a cool reception."

Down the price scale the picture is the same, only steadier. All eight Kusama editions at Phillips sold, for a combined HK$2.21 million at hammer against an aggregate estimate of HK$1.48 million to HK$2.32 million, as reported by MyArtBroker. A few pumpkin prints cleared their high estimates. None of it is a posthumous premium. It is a market that was already firm, the Pumpkin print median had risen 21% in the twelve months before her death, per the same report, and that simply stayed where it was.

Tsui's point deserves to be taken seriously rather than as spin. The "death effect" is a story told about artists whose careers end unexpectedly. Kusama worked into her late nineties, her studio produced at volume for decades, and every serious collector of her work had been pricing her age for years. There was no surprise to capitalise. What her death changes is supply over the next decade, and that depends on the studio and the estate, about which nothing has been said publicly. One sale cannot answer it.

Where the competition was

The bidding fights were somewhere else, and they followed a pattern we have described before: material that had been off the market for a long time, in a single owner's hands, offered without a safety net.

Sotheby's opened the week on September 28 with The Foujita Lexicon: Works from the Lewis Collection, its first single-artist sale in Asia. All 15 lots sold, 14 of them above the high estimate, and the sale had no guarantees, as reported by HENI. Le rêve (Hommage à La Fontaine) (1949) went for HK$26.52 million after 32 bids, about four times its high estimate, per Sotheby's results as reported by Artdaily. A small 1933 sleeping figure, Madeleine endormie, sold for $554,800 against a low estimate of $38,200, as reported by HENI.

That is what fresh supply looks like: a collection nobody had been able to buy from, estimates set low enough to invite a crowd, and no guarantor taking the upside. Sotheby's also set an auction record for any Vietnamese work with Vu Cao Dam's Conversation d'élégantes au jardin at HK$28.96 million, and artist records for Park Seo-Bo, Hu Xiaoyuan, Li Hei Di and Tran Luu Hau. Its four sales totalled HK$955.98 million, with 91% of lots sold, the house's best Hong Kong total since autumn 2023 and 35% above March.

The totals, read carefully

Christie's evening sale made HK$726.4 million, about $92.6 million, up 28% on the year with every lot sold, led by Jean-Michel Basquiat's Ancient Scientist (1984) at HK$76.98 million, about $9.8 million, as reported by Artdaily from the house's release. Phillips, much smaller, made HK$52.65 million in its evening sale, led by a Gerhard Richter Abstraktes Bild at more than HK$23 million, per its own results. By our sum of the houses' figures, the three evening sales came to about $186 million.

Those are better numbers than Hong Kong has posted in a while, and they are worth reading the way we read the first half of the year. The top lots were a Basquiat, a Richter, two Naras and two Kusamas: names a buyer can resell anywhere. The excitement was in the Foujita sale and the Southeast Asian records, which is to say in categories where Asian collectors know more than the rest of the market. The middle, the living Western mid-career painter at a few hundred thousand dollars, is not in these headlines because it is not where the bidding was.

What to watch

The London evening sales run around Frieze week, which opens on October 14, and Paris follows around Art Basel Paris. Two things to check there. First, whether consignors who held back Kusama paintings through the summer now send them, which would test whether this week's flat prices hold with more supply on the floor. Second, whether any house tries the Foujita formula in Europe: a single-owner group, no guarantee, low estimates. If it works twice, it stops being an anomaly and becomes the template for the season.
