Artmarket.com said Thierry Ehrmann, its Founder and CEO, his family and Groupe Serveur, the majority shareholder, plan to increase their holdings through additional purchases of Artmarket.com shares. The company said the transactions are intended to reaffirm confidence in Artprice by Artmarket.com and support its growth, not to initiate a takeover bid or squeeze-out offer. Required disclosures will be filed with the AMF, France’s financial markets authority, through its secure ONDE platform and within legal deadlines, with purchases made during authorized trading windows. Artmarket identified three filings: No. 2026DD1133787, published Aug. 17, 2026; No. 2026DD1134265, published Aug. 20, 2026; and supplementary filing No. 2026DD1134267, also published Aug. 20, 2026. Nadège Ehrmann, a member of Artmarket.com’s Board of Directors, acquired additional shares and disclosed the purchases to the issuer and AMF after their aggregate value exceeded the statutory threshold under Article 19 of the EU Market Abuse Regulation. The company is investing in its proprietary vertical AI systems, Intuitive Art Market and Blind Spot. Thierry Ehrmann has completed an 1,800-page philosophical and scientific treatise on artificial intelligence from 1987 to the present, including about 450 documented pages on Artprice’s history and AI-first transformation. An English edition is planned for late August 2026 on OpenAI, Gemini and Artprice by Artmarket.com, followed by a French edition in September. Artmarket.com is listed on Eurolist by Euronext Paris and operates Artprice, which it describes as a global leader in art-market information, with databases containing more than 30 million indices and auction results covering more than 915,300 artists.
