Sotheby's Acquires Mei Moses Art Indices

market-auction · 2026-05-05

Auction house Sotheby's has announced the acquisition of the Mei Moses Art Indices, a leading analytical tool for tracking art market trends through repeat sales data. The index, now renamed Sotheby's Mei Moses, maintains a database of 45,000 repeat sales across eight categories, with about 4,000 transactions annually. Sotheby's aims to leverage this data to enhance client services and identify market trends amid recent softer financial results. Notably, rival Christie's has been both a client and data supplier to Mei Moses. Other major art market indices include Artnet Indices, covering 1,600 auction houses globally, and the Artprice Global Index, which uses repeat sales methodology from 4,500 auction houses but excludes online sales. Sotheby's Executive Vice President Adam Chinn stated the acquisition will provide collectors with proprietary insights and help drive innovation.
