New York's spring auction week, starting May 18, 2026, saw record-breaking sales led by Christie's, which realized over $1.1 billion across two opening night sales. Major estate consignments from Condé Nast owner S.I. Newhouse, MoMA trustee Agnes Gund, dealer Marian Goodman, and financier Robert Mnuchin fueled the market, resulting in 17 new artist auction records.
Sotheby's Modern Evening Auction on May 19 achieved $304 million with a 98% sell-through rate across 45 lots, more than doubling the total from the equivalent sale in November. The auction was anchored by fresh-to-market masterpieces, including Henri Matisse's "La Chaise Lorraine" from the Barbier-Müller collection, which sold for $48.4 million—the second-highest price for a Matisse painting at auction. Other highlights included works from the Enrico Donati collection, which generated a combined $58.9 million, and Pablo Picasso's "Arlequin (Buste)" (1909) selling for $42.6 million. The sale contributed to a running combined total of $839.6 million for Sotheby's marquee sales, following strong results from the Mnuchin collection and Contemporary Day Auction.
TEFAF New York returned to the Park Avenue Armory with record attendance on its Collector Preview day, May 14, featuring 90 exhibitors showcasing modern and contemporary masterpieces, antiques, decorative arts, and jewelry. Dealers reported strong sales across price tiers, including an Andy Warhol Mao sold by ML Fine Art within the first hour, a Lucio Fontana *Concetto Spaziale* for $2.3 million at Mennour, and works by Giorgio Morandi, Giosetta Fioroni, and Meret Oppenheim sold by Galleria d’Arte Maggiore g.a.m. A new secondary-market partnership, Pace Di Donna Schrader Galleries, debuted with a booth anchored by a 1956 Rothko, signaling renewed confidence in the market.
