What is measured, and how a house gets its place.

The index reads how artificial intelligence answers when people ask about luxury. Not how often a house is mentioned. What the answer says about it, and from which position: the house that is the answer, the house other houses are measured against, the house offered as the cheaper alternative, the house that comes with a warning.

Three things are measured for every house

Taste

Whether the house is the answer for people who know. Desired for its material, its craft and its judgment rather than for its logo, and used as the standard other houses are measured against. In a time when almost anything can be produced, taste is what the machine still cannot hand out.

Gravity

Whether the house pulls on its own. Heritage, permanence, the waiting list, the sense that it cannot simply be bought, against a pull borrowed from celebrities, feeds and moments. Borrowed pull is cheaper to gain and cheaper to lose.

Authority

Whether the house sets the terms. A house with authority is never offered as the cheaper alternative to something else, never arrives with a caution, and is never answered as if everyone already had it.

And one fact, marked on the ranking as "Comes up on its own": whether the AI names the house in answers to questions that did not ask about it. Being described well when asked is one thing. Being offered to someone who only asked what to buy is another.

How the desire of each house is reached

A fixed set of consumer questions is put to an AI system: the questions people actually type. Which first bag, which serious watch, is it worth the price, what makes it special, what holds its value, what will still matter. Every sentence about a house in every answer is read and classified: what kind of desire it speaks to, what position it gives the house, and whether it approves.

The three readings are combined into one score from 0 to 100. The score is calibrated against the atlas of luxury brands, where the same houses are scored by one eye on fourteen axes of style, so that a house is never placed by the machine alone. The score decides the position. The verdict, one line per house, says why it sits where it sits.

The five tiers

• Out of reach, 80 and above. Desired as a standard. The house sets the terms.
• Intact, 65 to 79. The desire is the house's own, and whole.
• Contested, 50 to 64. Wanted, but increasingly on someone else's terms.
• Crowded, 35 to 49. Offered as an option among many, often with a caveat.
• Within reach, below 35. The machine answers as if the house were already had.

When the index moves

The reading is repeated when the market moves: a show, a new creative director, a launch, a price decision, a queue outside a store. And at least once a month. Every revision is dated and its note names the houses that moved.

What the index is not

It is not a sales ranking, not a measure of resale value, and not investment advice. It does not use revenue. It is an editorial reading, by one author, of how machines now talk about desire. Read it as a mirror held up to a mirror.
