.ai is the one extension outside .com with a real retail middle: a median near $10,000 across hundreds of reported sales a year, and a top end that produced the first seven-figure .ai sale in 2026. Single dictionary words carry the ceiling; the volume is in two-word brands and short brandables. Adoption is strongest where English and technology overlap, the United States, the United Kingdom, Singapore and India, and still light in China, which shapes which letter patterns sell.

We price .ai on its own curve, calibrated against these sales, and we track its finite classes: every three-letter name is now registered, the four-letter consonant-vowel names are going, and both are recorded below.
