The Market for Human Purity: When AI Disclosure Turns Absence into a Measure of Value

A work sells. In the technical documentation, beside materials and dimensions, a new line appears: “AI Generation: 0%.” The figure has nothing to do with the work itself. It answers to the market. From the auction room to the independent gallery, this number became, sometime around 2025, something no one discusses openly but everyone includes: a declaration of purity. Not an authenticity certificate in the traditional sense, but something more precise and more powerful: the certification of an absence.

The EU AI Act, in its most stringent enforcement phase between 2024 and 2025, established disclosure obligations for content generated or modified by AI systems. The institutional logic was legible: transparency as protection, as the public’s right to know what it is looking at. That logic had coherence in the domain of information, political communication, journalism. Transposed into the field of art and collecting, it produced an effect the architects of the legislation likely never intended: a new authentication mechanism, more sophisticated and more pervasive than any prior system.

What appeared as a regulatory opening has revealed itself, in concrete application, as a mechanism of closure. Mandatory disclosure generated a purity market: a system where “how much AI” functions as a price signal, where the percentage of algorithmic intervention becomes a proxy for human intention, where artists must quantify their presence in a work before the work can circulate. Transparency produced a new form of opacity, harder to perceive because it wears the face of honesty.

We observe this process from a position that is both privileged and uncomfortable. We see it unfold in real time, in the rooms where decisions are made, in conversations between gallerists and collectors, in legal briefings translating regulatory guidelines into commercial policy. What we see resembles an orthodoxy more than a liberalization, and it is more sophisticated than previous orthodoxies precisely because it is encoded in percentages rather than in judgments.

The question this essay holds open, without any pretense of resolving it, is the one no one wants to formulate explicitly: has mandatory AI disclosure created a market for human purity more effective and more pervasive than the authentication systems it nominally replaced? And if so, what does this tell us about the relationship between regulation, market logic, and the production of value in contemporary art?
