A program run by the government, or by one of the major AI labs, is fine. Must be a way for a large number of artists to be financially compensated for their work. It's fine if it requires an opt-in or active participation from the artist. Can't be restricted to a specific platform where the artist posted their art (deviantart, twitter, etc), but if most such platforms have a way for artists to be compensated then resolves YES. Can't be restricted to only the most successful artists.

Criteria may be modified during the first week of the market, suggestions welcome.

Good chance this market already exists, but I was unable to find it because manifold search, if you know of it please link it!
