**si.gov** was registered on October 1, 2026, by the Executive Office of the President under the .gov TLD, shortly after the September 29 executive order directing federal agencies to adopt “Super Intelligence” (SI) terminology in place of artificial intelligence (AI). The move aligns with a companion order establishing America.gov as an SI-enabled, conversational portal for federal services. Traders are watching implementation speed, agency website updates, and any public beta or DNS activation of si.gov itself. Historical .gov launches often move quickly once domains are secured, but bureaucratic coordination and security reviews can introduce short delays. Key near-term catalysts include the first agency compliance reports and any White House announcements on rollout milestones.
