The concentration of power in a few digital technology companies has become a subject of increasing interest in both academic and non-academic discussions. One of the most noteworthy contributions to the debate is Lina Khan's Amazon's Antitrust Paradox. In this work, Khan contends that Amazon has systematically exerted its dominance in online retail to eliminate competitors and subsequently charge above-market prices. This work contributed to Khan's appointment as the chair of the US Federal Trade Commission (FTC), one of the most influential antitrust organizations. Today, several ongoing antitrust lawsuits in the US and Europe involve major technology companies like Apple, Google/Alphabet, and Facebook/Meta. In the realm of generative AI, we are once again witnessing the same companies taking the lead in technological advancements, leaving little room for others to compete. This article examines the market dominance of these corporations in the technology stack behind generative AI from an antitrust law perspective.

翻译：数字科技公司权力集中问题已成为学术界及非学术讨论中日益关注的焦点。在此辩论中，莉娜·汗的《亚马逊的反垄断悖论》是最具影响力的著作之一。该文指出，亚马逊系统性地利用其在在线零售领域的主导地位排除竞争对手，随后收取高于市场水平的价格。这一研究推动了汗被任命为美国最具影响力的反垄断机构之一——联邦贸易委员会主席。当前，美欧多起反垄断诉讼涉及苹果、谷歌/字母表、脸书/元宇宙等大型科技公司。在生成式人工智能领域，我们再次目睹这些企业主导技术革新，令其他竞争者难以立足。本文从反垄断法视角，审视这些企业在生成式人工智能技术栈中的市场支配地位。
