AI had its decade. SI is the next one — and it has exactly one address.
In September 2026 the US government officially renamed artificial intelligence: it is now Super Intelligence — SI. Within days Elon Musk and Nvidia’s Jensen Huang were saying it too. On the entire internet, only one extension spells it: .si.
In their words
“No more AI. SI. It’s better.”
“Welcome to the new world of super intelligence — SI.”
“These are really SI factories, superintelligence factories.”

Why .si is the one
The only address that spells SI
There is exactly one .si. No new extension can ever spell it — it is a permanent two-letter country code. Every SI company that wants its category in its address has one option.
.ai already proved the playbook
When AI took off, .ai became the industry’s default address and earned Anguilla close to $100 million in three years. “Super” is the next word — and .si is its .ai.
Super beats artificial
Two letters, the same length as .ai — carrying the term the US government now uses officially, and that tech leaders are already saying out loud.
Every great word exists once
46,066 .si names were registered in September alone. The best one-word names go first — and once taken, they’re gone. This collection holds 1,130 of them.
Established and trusted
.si is an established European country code run by ARNES, Slovenia’s national academic and research network — not an experimental new extension.

AI was artificial. SI is super.
The companies that defined the AI decade own their one-word .ai. The companies of the SI decade are choosing their .si now — and every great word exists only once.
