The present study examines how familiarity with and trust in AI shape consumers\u2019 acceptance of AI-based advertising and, in turn, their ethical purchasing behavior. Data were collected from 505 Greek consumers through an online survey and analyzed using hierarchical and logistic regression models. Reliability and validity tests confirmed the robustness of the measurement instruments. The results show that familiarity with AI technologies significantly enhances trust and ethical confidence toward AI systems. In turn, trust in AI strongly predicts the consumers\u2019 acceptance of AI-driven advertising, while acceptance positively affects ethical consumption intentions. The findings also confirm a mediating relationship, indicating that acceptance of AI-based advertising transmits the effect of AI rust to ethical consumption. By integrating ethical and technological dimensions within a single behavioral model, the study provides a more comprehensive view of how consumers form attitudes toward AI-enabled marketing. Overall, the findings highlight that transparent and responsible AI practices can strengthen brand credibility, foster ethical engagement, and support more sustainable consumer choices.<\/jats:p>","DOI":"10.3390\/digital6010001","type":"journal-article","created":{"date-parts":[[2025,12,19]],"date-time":"2025-12-19T14:27:16Z","timestamp":1766154436000},"page":"1","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Ethical Consumer Attitudes and Trust in Artificial Intelligence in the Digital Marketplace: An Empirical Analysis of Behavioral and Value-Driven Determinants"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-1890-7688","authenticated-orcid":false,"given":"Markou","family":"Vasiliki","sequence":"first","affiliation":[{"name":"Department of Management Science and Technology, University of Western Macedonia, 50150 Kozani, Greece"}]},{"given":"Panagiotis","family":"Serdaris","sequence":"additional","affiliation":[{"name":"Department of Management Science and Technology, University of Western Macedonia, 50150 Kozani, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5008-2935","authenticated-orcid":false,"given":"Ioannis","family":"Antoniadis","sequence":"additional","affiliation":[{"name":"Department of Management Science and Technology, University of Western Macedonia, 50150 Kozani, Greece"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0147-4155","authenticated-orcid":false,"given":"Konstantinos","family":"Spinthiropoulos","sequence":"additional","affiliation":[{"name":"Department of Management Science and Technology, University of Western Macedonia, 50150 Kozani, Greece"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1177\/1094670517752459","article-title":"Artificial Intelligence in Service","volume":"21","author":"Huang","year":"2018","journal-title":"J.
