.SI domain names have been the ccTLD for Slovenia since 1992. More recently, the SI term has become associated with Superintelligence in the same way AI is a common acronym for Artificial Intelligence. I shared my thoughts on the .AI and .SI discussion yesterday.
This morning, Namecheap and Spaceship Founder Richard Kirkendall announced .SI domain names were available to register and transfer at Spaceship. He also announced the price for registrations and renewals:
Just onboarded .si domains at Spaceship. Launch price is $10.98 per year with no limits and $11.98 for renewals! 🔥🚀

To help people discover and uncover domain names with potential in the .SI TLD space, NameBio shared a .CSV file with its publicly recorded .AI domain name sales:
For your .si bulk checking pleasure… 🫶

I think the idea is that if a domain name sold in .AI it could have similar interest in .SI. That may be the case, but .AI domain names have been bought en masse speculatively, and I think .SI is an even more speculative extension at the moment.
I suspect most of the most appealing .SI domain names have already been purchased by domain investors and speculators. While I have seen some .SI sale reports, I have not seen a whole lot of usage by end user companies, which is what I think would drive growth. That remains to be seen.
Congratulations to those domain investors who previously bought .SI domain names and have made some deals, and good luck to those who are buying them now.
