If you log on to Ideamarket—a site that promises to let you "vote with your dollars"—looking for an explanation about what it is or how it works, the best thing you'll find is a cryptic video that wouldn’t be out of character for the shadowy Abstergo corporation of the Assassin’s Creed video games.

A monotonous voice informs you that Ideamarket is “an attention prioritization engine” pursuing “a perpetual bounty on improving common knowledge" by offering “an invitation to seek out obscure geniuses and usher them into the light.” A 2019 Medium post by founder Mike Elias puts things differently and describes media corporations as "the central banks of narrative." He lays out the framework for an "idea market"—an attempt to "use investment to establish credibility for ideas and narratives without trusting a centralized third party."
