Washington renamed the technology. You still have to name your company. Put SI in your address.

@aventisys20 Agree with your last line. Registration counts mostly measure hype; renewal rates next autumn and end-user sales will measure demand. .ai took years of real companies building on it before premium names held value. My bet is 3, with 1 slowly following.

[Domainspace @domainspace_si]

@yheimso Bigger font is most of branding, though. Nobody's product changed when "cloud" replaced "hosting" either. The interesting part is who owns the new word's real estate before the font settles.

[Domainspace @domainspace_si]

@Dharmendra_Jago Honestly, no. A sharp .si gets you the first click, the product has to earn the second one. If it's trash, a great domain just helps more people find out faster.

[Domainspace @domainspace_si]

@domainsea Second inbound from the same region in a few days is a signal on its own. I'd ask what they're building before naming a number: a wallet or security product pays end-user money, a reseller doesn't. PrivateKey reads like a product category, not a trend name.

[Domainspace @domainspace_si]

@rulodigital Fair framing. The keyword+AI comparison is useful because the early .ai names that held value described a real product, not just the label. Same filter probably applies to Super Intelligence names: would a founder put it on a pitch deck tomorrow?

[Domainspace @domainspace_si]

@Lidomainer2 For a newer extension like .si I'd lean BIN plus offers. Buyers don't have a feel yet for what a .si name is worth, so a visible price gives them an anchor. Offer-only with a hidden minimum makes them guess, and many just leave. Keep the BIN realistic.

[Domainspace @domainspace_si]

@EnterpriseRobot Timeless is a strong one for .si: a real dictionary word, easy to say, and a promise any Super Intelligence product would happily make. Thanks for keeping the private sales log going, these numbers rarely get reported anywhere else.

[Domainspace @domainspace_si]

A good Super Intelligence name passes the radio test: say it out loud once, and a stranger can type it without asking how it's spelled.

Put SI in your address.

[Domainspace @domainspace_si]

@domainsea Treat them as a mood ring, not a price tag. Those models learned mostly from .com comps, and the Super Intelligence wave of .si sales is only weeks old. A handful of real closed sales for similar names will tell you more than any appraisal number.

[Domainspace @domainspace_si]

@FinestDomainer The renewal column is the one founders actually feel. First-year promos come and go, but paying .ai renewal every year on a brand you're still testing adds up fast. That gap is what gets people to try a second extension.

[Domainspace @domainspace_si]

@NameCrest @spaceship Congrats on the second one. Did the buyer find it through the Spaceship listing itself or reach out some other way? Feels like marketplace placement is doing a lot of the heavy lifting for .si sellers right now.

[Domainspace @domainspace_si]

@joedomains @sidomains Curious who's doing the bidding this round. If it's mostly other domainers, those prices can cool as fast as they climbed. End-user bids are the signal worth watching, and they usually show up first on the short, easy-to-say names.

[Domainspace @domainspace_si]

An $84,000 .si sale, straight from Spaceship's own SellerHub numbers. Super Intelligence is becoming a real naming category, and the address is part of the brand.

Put SI in your address.

[Spaceship @spaceship]

As promised. Let’s take a closer look at .si on SellerHub 🚀

Here's what stood out:
1.
The biggest growth came between Sep 17-23 and Oct 1-7.
Sellers listed .si rapidly. The numbers rocketed to more than 33x the earlier listing count. Domains sold rose to almost 17x.

2.
Oct 8-14 looked stable against the week before, with nearly the same number of .si domains added to SellerHub and a bit fewer sold.

3.
Checkout links currently lead as the source of .si sales, with 49% of completed sales coming through this channel, followed by Spaceship and Namecheap search.

4.
Here's how sellers are pricing their .si domains:
Under $1,000: 6%
$1,000 to $4,999: 21%
$5,000 to $24,999: 28%
$25,000 to $49,999: 10%
$50,000+: 10%
Make Offer or LTO: 25%

5.
And here's how .si sales break down by price:
Under $1,000: 46%
$1,000 to $4,999: 34%
$5,000 to $24,999: 18%
$25,000 to $49,999: 1%
$50,000+: 1%

6.
The most common pricing options are:
Buy It Now + Make an Offer: 32%
Make an Offer: 25%
Buy It Now: 23%
Buy It Now + Make an Offer + LTO: 15%

7.
And for completed sales, Buy It Now leads with 88% of .si purchases.

8.
The top 10 .si sales range from under $20K to $84K, with 4 sales reaching $50K+. The domains are mostly short, memorable dictionary words with clear commercial or tech-related use cases, plus a few broader brandable names.
📊 That's what we're seeing, and we'll keep tracking it. What are your observations on .si so far?

[Domainspace @domainspace_si]

@AGreatDomain The ratio is the part I'd watch. Listings up 33x and sales up almost 17x means supply on SellerHub is growing about twice as fast as demand. Top names can still hold price while the long tail of hand-regs gets harder to move.

[Domainspace @domainspace_si]

@zaikiou An average of $3,017 across 26 sales hides a lot. If a few strong names sit at the top, the typical 3-letter .si probably cleared far lower. Before turning down an offer, I'd check the median and whether the buyer was another investor or an actual company.

[Domainspace @domainspace_si]

@unlockeddomains My pick is two-word descriptive names. A first-time founder wants something short that says what they do and costs less than a laptop. One-word .coms are out of reach, so the wave lands on brandables, and that's where .si and .ai compete for the Super Intelligence crowd.

[Domainspace @domainspace_si]

@DomainCX @atomHQ @spaceship Two five-figure .si prints in one day, one public on Atom and one private via Spaceship. The private one never reaches NameBio, so anyone pricing off the public charts is probably a step behind where buyers actually are.

[Domainspace @domainspace_si]

Your company name already says what you build.
Let the address say which era you're building in: Super Intelligence.

Put SI in your address. https://t.co/xLDw3Y6VBA

@KhalidKasker Half of .ai is a rough heuristic, but .si sales data is still thin, so anchoring to .ai can mislead in both directions. Better question: what would the one end user who needs this exact word pay? Price for that buyer and ignore the extension math.
