The .ai domain is the country-code top-level domain (ccTLD) for Anguilla, a Caribbean territory, but it is used worldwide as the go-to extension for artificial-intelligence products and startups. It is open to anyone, carries premium pricing, and has become a major revenue source for Anguilla's government.

Where to register a .ai domain
Prices are indicative and set by each registrar; .ai has often been sold on a two-year minimum term, so the up-front total may differ. Links may be sponsored. tldlist.us is an independent reference and not a registrar.
What does .ai mean?
On paper, .ai is the country-code top-level domain for Anguilla, a small British overseas territory in the Caribbean. It was delegated back in 1995, and its two letters come from Anguilla's ISO country code, not from any technology term. The IANA root zone lists it as Anguilla's national domain, and the registry is run directly by the territory's government.
What changed everything was a coincidence of letters. As artificial intelligence moved from research labs into mainstream products, every AI company wanted a name that screamed "AI" — and .ai already spelled it perfectly. Demand exploded. The extension became the default badge for AI labs, model providers, copilots and tools, with high-profile names like x.ai adopting it. For Anguilla, a territory of only a few thousand residents, the result has been remarkable: .ai registration fees now contribute a substantial and growing share of the government's revenue.
Who uses .ai?
The artificial-intelligence industry, almost by definition. Foundation-model companies, machine-learning startups, AI-assistant products, data-science platforms and research labs reach for .ai to make their focus instantly legible. The extension signals "we build AI" before a visitor reads a single word of the page, which is exactly what a crowded, fast-moving market rewards.
Beyond pure AI firms, plenty of adjacent products — analytics tools, automation platforms and developer services with an AI angle — use it too. Because the meaning is so on-the-nose, a .ai works best when artificial intelligence is genuinely central to what you do; using it for an unrelated business can read as a stretch.
.ai registration rules and requirements
.ai is an open ccTLD: anyone worldwide can register one, with no Anguillan residency, local presence or documentation required. The one historical quirk to know is the term length — for years .ai was sold on a two-year minimum registration rather than the usual one-year cycle, which affects how the cost is quoted and renewed. Always check whether you are buying one year or two, and confirm the renewal terms. Administration runs through Anguilla's government registry under ICANN's ccTLD framework, with standard contact-data requirements.
How much does a .ai cost?
A .ai is one of the more expensive mainstream extensions, commonly around $60–$100 per year with $70 a typical figure. The two-year minimum that has historically applied means the up-front charge can be roughly double a single year's price, so a "$140" sticker often represents two years rather than one. Short and high-demand AI names trade for large sums on the aftermarket, mirroring the gold-rush appetite for the extension.
| Registrar | Typical .ai price (per year) |
|---|---|
| Cloudflare Registrar | At wholesale cost (~$60–65) |
| Porkbun | ~$65/yr |
| Namecheap | ~$70–90/yr |
| Premium / aftermarket names | $10,000s and up |
Is .ai good for SEO?
Yes. Search engines do not penalise .ai, and although it is technically a ccTLD, in practice a well-built .ai site ranks globally on the strength of its content and links. There is no algorithmic boost for having "ai" in the extension, but there is a strong topical-relevance and click-through benefit when your site really is about artificial intelligence — users scanning results see a name that matches their intent. The extension is SEO-neutral; the relevance halo is a human effect. For more, see how to choose between TLDs.
.ai vs alternatives
For an AI company specifically, .ai is hard to beat — its only real rival is the .com of your brand name, which many AI startups buy alongside .ai for safety. If a great .ai is unavailable or the price is off-putting, the closest alternatives are .io (the broader startup standard), .dev for developer-facing tools, .app for shipped applications and .tech for general technology branding. None of those names your category as precisely as .ai, which is precisely why .ai commands its premium. Compare them side by side on our comparison page.
