This chapter introduces the concept of the technopolar world as a foundational rethinking of global politics in the digital age. While building on Ian Bremmer’s notion of the “technopolar moment,” which highlights the temporary rise of tech companies as quasi-sovereign actors, it moves beyond that framework to propose a long-term structural transformation of international relations. In the technopolar world, technological infrastructure, algorithmic authority, and digital sovereignty emerge as the primary axes of geopolitical agency. While Big Tech firms exert significant influence over communication and financial systems, they are not fully autonomous actors; rather, they often operate in alignment with prevailing state interests. The chapter analyzes this dynamic through the cases of China, the European Union, and the United States, showing different modalities of state-tech power relations. It then outlines a new model of sovereignty based on three pillars: data sovereignty, algorithmic capacity, and hardware autonomy. Additionally, the energy–AI nexus is introduced as a critical component of national tech strategy. The chapter concludes by proposing cognitive diplomacy as a strategic response to the challenges of the technopolar age, emphasizing the integration of human and artificial intelligence in foreign policy. The technopolar world is not a transient moment, but a new geopolitical condition.
