Expiry

When does claude.ai expire?

claude.ai's current registration runs until 4 August 2029. Expires in 1040 days.

The owner can renew at any time before then, which moves the date forward by the renewal term. Large brands usually renew years ahead.

  1. Registered
  2. Grace period 45 days
  3. Redemption 30 days
  4. Pending delete 5 days
  5. Released

What happens if it isn't renewed?

An unrenewed .ai name passes through fixed phases before it is released: a 45-day grace period in which the owner can still renew at the normal price, a 30-day redemption period in which recovery costs a fee on top of renewal, then 5 days pending delete, when no one can renew or register it. The durations are the .ai registry's published figures.

When could it drop?

Only if it is not renewed. The earliest it could be released is 23 October 2029, if every phase runs its full length.

How the .ai lifecycle works

Availability

Is claude.ai available to register?

No. claude.ai is registered, so a registration attempt today would fail.

It only becomes available if the owner lets it lapse and it clears every phase above. Domain Watch checks the name twice a day and sends one email the day it is released.

Age

How old is claude.ai?

claude.ai is 8 years old: it was first registered on 4 August 2018.

The creation date is when the current registration began. A name that dropped and was re-registered gets a new creation date, so this counts continuous registration, not first use.

The Internet Archive first captured a page on claude.ai on 29 November 2021 and holds captures from 5 different years.
