The article identifies the mechanism through which technological innovations are converted into sustainable market power of digital platforms in the global tourism industry. The concept of the technological package of platform transformation is substantiated. This concept encompasses six groups of technologies: connectivity, mobility, cloud computing, big data, software interfaces (APIs), and generative artificial intelligence. These technologies act in a complementary and cumulative manner, and it is the completeness of the package that explains the timing and depth of the platform revolution in the industry. It is demonstrated that the package translates into dominance through three cumulative assets - network effects, data, and ecosystem connectedness - which form a self-reinforcing loop resilient to attacks on any single element. The channels through which generative artificial intelligence influences the configuration of market power are systematized, and it is argued that under inertial development the new technological wave reinforces, rather than undermines, the established loop. Policy implications are formulated: the target of economic policy should be the breaks in the loop - data access, reputation portability, and interoperability - rather than individual manifestations of platform power.
