A surprising shift in the Domain name world followed President Donald Trump’s September 22 address to the United Nations General Assembly, where he proposed referring to Artificial Intelligence as “Super Intelligence,” or “SI.”
The reaction was almost immediate. In the 25 hours following the speech, registrations of Slovenia’s .si country-code domain reportedly overtook .ai, showing how quickly a change in terminology can influence the domain market.
But the connection between .si and the AI industry was already beginning to emerge. In May 2026, AI startup Recursive Superintelligence raised $650 million at a reported $4.65 billion valuation and acquired the domain Recursive.si. The move highlighted the potential of .si as a meaningful branding and defensive domain extension for technology companies.
This is where Domgate, as a corporate ccTLD domain registrar, plays an important role. Domgate helps corporates and brand-protection registrars secure .si Domains, enabling businesses to protect their brands and key digital assets across relevant country-code extensions.
Whether .si becomes a long-term domain trend will ultimately depend on whether “Super Intelligence” gains wider adoption. For now, however, two simple letters have created an unexpected new connection between Slovenia, domains, and the future of AI.
