Artificial intelligence is rapidly transforming political institutions and public life. The central research problem of this research article is to examine how AI reshapes governance structures, civil liberties, electoral politics, economic distribution and geopolitical competition. While AI promises efficiency and innovation, it also raises concerns about accountability, bias, surveillance and democratic legitimacy. The study seeks to understand how different political systems respond to these opportunities and risks. The research adopts a qualitative comparative methodology. It draws on secondary sources including academic literature, policy documents and institutional reports. The analysis compares democratic and authoritarian contexts to identify patterns of institutional adaptation. Thematic analysis is used to examine governance transformation, surveillance expansion, digital political communication, labour market restructuring and regulatory frameworks. The study concludes that the political consequences of artificial intelligence will depend not only on technological capacity but also on deliberate policy choices and institutional resilience.
