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 organisations. 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：少数数字科技公司的权力集中已成为学术界和非学术界讨论中日益受关注的议题。其中，莉娜·汗所著的《亚马逊反垄断悖论》是这场辩论中最引人注目的贡献之一。在这部著作中，汗认为亚马逊系统性地利用其在在线零售领域的主导地位排挤竞争对手，随后收取高于市场水平的价格。这部著作促成了汗被任命为美国联邦贸易委员会（FTC）主席，该机构是最具影响力的反垄断组织之一。如今，美国和欧洲多起正在进行的反垄断诉讼涉及苹果、谷歌/阿尔法贝特、脸书/元宇宙等大型科技公司。在生成式人工智能领域，我们再次目睹这些相同的公司在技术进步中占据领先地位，留给其他竞争者喘息的空间微乎其微。本文从反垄断法的角度审视了这些公司在生成式人工智能技术堆栈中的市场主导地位。
