The global art market was valued at $67.4 billion in 2018, the second highest year ever.
The United States, United Kingdom and China are the three largest art markets in the world. Their sales combined make up 84% of the global art market.
The auction house is one of the biggest drivers of the art market. Sales at public auctions exceeded $29 billion last year. Two auction houses - Christie's and Sotheby's - compete head to head each year capturing more than 40% of global auction sales.
