LiveArt.ai maintains a very large database of auction sales results. For each artwork in our database, we use our machine learning algorithms to compute the artwork’s LiveArt Estimate™ and price history over time. An Artist Index for a given Artists is an aggregate of the price histories of all of the Artist’s artworks, normalized against the first sale for this Artist recorded in our database. We further sub-divide the Artist Index by artwork types — paintings, works on paper, sculptures, etc. — to give LiveArt.ai users the ability to track the market for a given Artist with more granularity.
