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.
