Ratings
One grade for an artist, a work, a gallery, or a collection
One letter grade covering how strong a market is, how easily the work sells, and how well value has held. Built for lending and credit decisions. Same underlying data as the index.
Where this stands
We are still writing the grading method and the bar a rating has to clear to stand up in a lending decision. Lawyers are involved. This page is what we are building, not something you can order today. If a rating would help, leave your details and we will come back to you when it is live.
What it covers
Artist
How strong the artist's market is overall: how established it is, how steadily work trades, how value has held across cycles.
Artwork
One specific work, taking its medium, period, provenance, and condition into account alongside the artist's market.
Gallery
A gallery's programme: the depth of the roster, the exhibition and sales record, how represented artists have done.
Portfolio
A collection as a whole: how concentrated it is, how liquid, and how its value would be expected to hold together.
How a grade is built
- 1. Value first, from the index. The valuation under a grade comes from the same published index method as everything else here. It does not change based on who asks for the rating.
- 2. Grade on top. The grade is then applied on top of that fixed valuation, against written criteria: liquidity, market depth, price stability. It is never folded into the value.
- 3. Curator-reviewed. A person checks every grade before it goes out, the same review every published figure here gets.
