As announced in Artmarket.com's Q2 2026 press release published on August 13, 2026, under the title "Artmarket.com: Q2 2026 Growth — From Progressive Transition to Artprice's 'AI-FIRST' Mutation", Thierry Ehrmann, Founder and CEO of Artmarket.com, and his family reaffirm their complete confidence in the future of Artprice by Artmarket.com—the global leader in Art Market information—and in the sustained growth of its operations. This momentum is driven, in particular, by substantial investments committed to developing Artprice by Artmarket.com's proprietary vertical AI solutions: "Intuitive Art Market ©" and "Blind Spot ©".

The conviction of the Ehrmann family and Groupe Serveur, the majority shareholder, in the continued expansion of Artprice by Artmarket will materialize shortly through an increased equity stake in Artmarket.com via the acquisition of additional Artmarket.com shares. All mandatory regulatory disclosures will be filed with the AMF (the French Financial Markets Authority) and published online within legal deadlines, with share purchases executed strictly within authorized trading windows.

These current and upcoming transactions are intended solely to reaffirm their confidence in the future of Artprice by Artmarket.com and to provide full support to Artmarket.com. They are in no way intended to initiate a takeover bid or squeeze-out offer (tender offer / buyout), contrary to persistent misinterpretations across certain forums, nor do they involve any failure by the Ehrmann family to disclose transactions or threshold crossings.

The ONDE extranet (Outil de Notification et de Déclaration Électronique), the AMF's secure platform dedicated to filing official regulatory declarations (insider transactions, major shareholding threshold crossings, etc.), lists the following current and upcoming filings:
• 1st filing — No. 2026DD1133787 (published on 08/17/2026)
• 2nd filing — No. 2026DD1134265 (published on 08/20/2026)
• 3rd supplementary filing — No. 2026DD1134267 (published on 08/20/2026)

In alignment with this determination to increase the family's equity participation in Artmarket.com, Mrs. Nadège Ehrmann, Board Member of Artmarket.com, has acquired additional Artmarket.com shares. Because the aggregate total of her acquisitions exceeded the statutory regulatory threshold, she completed the mandatory disclosures with both the issuer and the AMF in full compliance with Article 19 of the EU Market Abuse Regulation (MAR).

Furthermore, these share purchases follow ordinary market price fluctuations, which in no way alter the Ehrmann family's commitment to reinforcing its equity position in Artprice by Artmarket.com.

By way of an iterative update, Thierry Ehrmann has completed the manuscript of an 1,800-page philosophical and scientific treatise dedicated to Artificial Intelligence from 1987 to the present day. The central chapters of this work (approximately 450 rigorously documented pages) chronicle the untold human odyssey of Artprice, culminating in the worldwide construction of a universal memory of the Art Market, forged through extraordinary encounters with the pioneers of Art Market sociology and historic market figures who have since passed away.

These historic relationships enabled Artprice to become the trusted custodian of the collective memory of these very figures. Among other insights, the work provides a scientific account of Artprice's "AI-First" transformation, grounded in a philosophical framework articulated in 2026 under the AI concept of "alignment."

This multilingual work will be distributed globally in a free digital edition and as a paid print edition in bookstores. The English version will be released in late August 2026 across OpenAI, Gemini, and on Artprice by Artmarket.com, prior to the launch of the French edition in September 2026.

This brief excerpt from the raw typescript illustrates both the literary style and the philosophical premise of the treatise—namely, the role of artificial intelligence in the formation of thought and memory:

"Artprice was not born to wrest secrets from the Art Market. It was born to prevent the public Market from succumbing to amnesia. This distinction is fundamental. It carries a specific conception of freedom. Transparency is not the abolition of privacy; it consists in rendering intelligible that which already belongs to the common sphere.

The more Artprice grew, the more we realized that we had become responsible for something far exceeding the mere economic and industrial function of a database. When you own a few books, you may do with them as you please. When you have gathered hundreds of thousands of unique fragments of the world's Art Market memory from across multiple continents, legal ownership does not absolve moral responsibility: it transforms you into a custodian of this universal Art Market memory.

To receive without erasing. To connect without standardizing. To measure without diminishing. To render transparent without desecrating. To leverage digital technology without supplanting the human gaze. To build a digital information economy without ever forgetting that behind every data point lies a work of art, and behind every work of art lies a human being.

For nearly thirty years, we lived by these principles without ever feeling the need to enshrine them in a manifesto. Then, artificial intelligence transformed the nature of the challenge. With AI, memory is no longer merely consulted; it becomes an absolute training ground for learning.

A vertical, proprietary AI can now navigate volumes of information that no assembly of art historians or researchers could absorb in a lifetime. Connecting. Correlating. Detecting patterns. Surfacing anomalies. Rebuilding affinities. Identifying blind spots. Generating algorithmic hypotheses. It is a power of extraordinary magnitude. Yet it makes the authenticity and quality of the primary source more vital than ever.

At that exact moment, the thousands of libraries we salvaged across the globe undergo another shift in status. They are no longer simply Artprice's past; they become the ultimate guarantee of its future. A vertical AI dedicated to the Art Market is meaningful only if anchored in a memory whose genealogy is flawlessly traceable across catalogues, manuscripts, codices, photographs, biographies, auction records, cross-verified sources, human corrections, and decades of rigorous standardization.

The source precedes the model. Always."
