Consignors Revealed: The Mystery Sellers Behind the $1.8 Billion May Auctions

Sotheby's kicked off the May auction season with a $433 million sale, including an 11-lot group from the estate of late dealer Bob Mnuchin, led by an $86 million Mark Rothko painting. The three major auction houses are offering $1.8 billion worth of art by low estimate, a 50% increase from last year, driven by consignments from estates of key figures like Mnuchin, philanthropist Agnes Gund, and dealer Marian Goodman. Christie's will stage a sale from publisher S.I. Newhouse's collection expected to bring $450 million, potentially setting records for Jackson Pollock and Constantin Brancusi. The article reveals that many top sellers are anonymous, but unmasked names include the Dennison family and French collector John Sayegh-Belchatowski.

S.I. Newhouse’s 11-Foot-Wide Jackson Pollock Drip Painting Sells for Record-Breaking $181.2 M.

A Jackson Pollock drip painting, *Number 7A* (1948), formerly owned by media magnate S. I. Newhouse, sold at Christie’s on Monday night for a hammer price of $157 million, totaling $181.2 million with fees. The work, measuring nearly 11 feet wide, received over 60 bids in a 10-minute bidding war and set a new auction record for the Abstract Expressionist artist, surpassing the previous high of $61 million set in 2021. The winning bid was placed by a buyer represented by Christie’s global president Alex Rotter, with Swiss mega-dealer Iwan Wirth acting as an underbidder, possibly for collector Laurene Powell Jobs.

Sotheby's kicked off New York's art and auction week with two major sales on May 14, 2026, led by the highly anticipated Robert Mnuchin: Collector at Heart Evening Auction. The top lot was Mark Rothko's "Brown and Blacks in Reds" (1957), which sold for $85.8 million, the second-highest price ever for the artist at auction. The Mnuchin auction achieved a "white glove" sale, selling all 11 lots for a total of $166.3 million, followed by The Now & Contemporary Evening Auction which brought in $266.8 million. Combined, Sotheby's generated $433.1 million, a 133% increase over its May 2025 session. The sales reflect a strong return of high-value trophy lots to the secondary market, driven by the dispersal of prominent collectors' estates.
