Amid a sluggish broader art market, the design category is surging. Major auction houses—Sotheby’s, Christie’s, and Phillips—held design sales in early June 2025 that far exceeded expectations. Sotheby’s New York design sales totaled $37.5 million, Christie’s $23.6 million, and Phillips $4 million, representing a 62.3 percent year-on-year increase across all three houses. Notable highlights include the Goddard Memorial Window by Tiffany Studios, which sold for $4.29 million, the second-highest price for a Tiffany window at auction. The sales attracted many new buyers, with Sotheby’s and Phillips reporting over 20 percent of buyers were new to the houses.
