The rapid expansion of digital markets has led to unprecedented economic
concentration, driven primarily by large technology platforms acquiring, integrating, or
excluding smaller competitors through mechanisms often referred to as “Tech-Over.”
This study offers a comparative legal analysis of how three diverse jurisdictions Turkey,
France, and Singapore are regulating this phenomenon. Using a qualitative case study
methodology, the research evaluates legal frameworks, regulatory instruments,
institutional capacity, and enforcement practices. The findings reveal that while France
employs an ex-ante model embedded in EU law, Singapore emphasizes adaptive,
guideline-based governance, and Turkey is transitioning toward more robust digital
oversight. Despite differences, all three jurisdictions converge on the need to monitor
data control, algorithmic opacity, and cross-market dominance. The article concludes
with policy recommendations for enhancing merger control, increasing institutional
capability, and fostering international cooperation. These insights contribute to global
debates on competition law reform and digital market governance in an era of platform
capitalism.
