TL;DR
- The thesis: the Antechamber — the space between the client's intent and the house's storefront — has been populated by AI agents the houses neither built nor control. 700 million weekly active users on ChatGPT worldwide (eMarketer). This is where desire now forms.
- Sephora (LVMH) launches its app inside ChatGPT (March 24, US pilot): Beauty Insider integrated, GPT vision skin analysis, -30% returns expected. Checkout to come. The same day, OpenAI withdraws Instant Checkout (3x lower conversion than retailer sites, Walmart).
- Kering appoints Pierre Houlès as Chief Digital, AI & IT Officer, with an explicit mandate to identify how "agentic approaches can reinvent key business processes." Capital Markets Day: April 16.
- Dior × Kahoona (LVMH Innovation Award 2025): +24.2% click-through rate, +12.8% average basket on anonymous visitors read in real time via their "digital body language." 96% of visitors activated without a cookie.
- Prada × Jordan Wolfson: SS26 campaign accused of using AI. Neither confirmation nor denial. BoF publishes "Is AI Antithetical to Luxury?" on March 25. EU AI Act Article 50: by August 2, 2026, marking AI-generated content will be mandatory.
PARADOX OF THE WEEK
The waitlist is not a logistics problem. It is an instrument of desire. The time that separates the craving from the object — weeks, sometimes months — is the very condition of value. Luxury houses have known this for two centuries: you do not facilitate the purchase, you earn it.
Sephora in ChatGPT. Gap in Gemini — Google Pay checkout, zero redirect. The agent answers in three seconds. Friction disappears.
Luxury built its power on the obstacle. The agent is a machine for removing obstacles. And the houses, one by one, are beginning to open the door.
But the door is worth pausing at. The same day as the Sephora announcement, OpenAI withdrew Instant Checkout from ChatGPT. Three times lower conversion than retailer sites, according to Walmart (Retail Gazette, March 24, 2026). Even the machine discovered that absolute fluidity does not produce sales. And OpenAI pivoted toward "discovery" — the moment when desire forms, not when it is consumed.
Daniel Langer, professor at NYU and Pepperdine, CEO of the agency Équité, framed it in March 2026: "AI makes everything abundant. When abundance is everywhere, scarcity becomes the ultimate currency." Luxury sells scarcity. The agent produces abundance. Does one die when the other thrives? Or will the houses that master the Antechamber be the ones that learned to reintroduce friction at the very heart of fluidity?

WHAT'S MOVING
Sephora (LVMH) enters ChatGPT
On March 24, at Shoptalk Las Vegas, Sephora announces the launch of its app inside ChatGPT — the first beauty brand to do so. The client states their request in natural language — a treatment, a color, a budget. They can connect their Beauty Insider account (80 million members): history, skin type, memorized preferences. GPT vision analyzes the selfie in real time, diagnoses the skin tone, recommends with the precision of a flagship advisor. Checkout within ChatGPT is not yet available — it is announced for a coming update, via the Agentic Commerce Protocol co-developed with Stripe. Anca Marola, Global CDO of Sephora: "Today this means piloting the Sephora app on new intelligent channels such as ChatGPT." Nick Turley (OpenAI): "ChatGPT is increasingly becoming a starting point for discovery and purchase decisions." Expected reduction in returns: 30%.
Sephora is not the heart of luxury. It is the signal the heart of luxury is watching.

Kering appoints a Chief Digital, AI & IT Officer — explicit agentic mandate
On March 17, Kering appoints Pierre Houlès to the position of Chief Digital, AI & IT Officer. Houlès comes from Renault Group, where he led the digital transformation since 2016. He joins the Executive Committee, reporting to COO Jean-Marc Duplaix. His official roadmap: identify how "agentic approaches can reinvent key business processes." All against the backdrop of a Capital Markets Day on April 16 — the first strategic presentation of the Luca de Meo era. The press release explicitly mentions Balenciaga × Intelo.ai (January 2026 partnership on agentic merchandising and retail planning) as the foundation to scale across the entire group. Kering chooses its moment: a group under pressure (-22% Gucci in 2025, restructuring underway) betting that agentic AI can be the operational lever that brand investment alone cannot activate.

Prada × Jordan Wolfson: "Is AI Antithetical to Luxury?"
On March 20, Prada publishes the SS26 campaign created with American artist Jordan Wolfson. Characters in armadillo-scale bodysuits, beak-like creatures in molded leather, hues that shift depending on the angle. The question circulates immediately: is this AI? Neither Wolfson nor Prada confirm. On March 27, an official Prada Instagram post specifies that "Prada never set out to use AI in its latest advertising campaign." A denial that only amplifies the doubt. On March 25, BoF publishes "Is AI Antithetical to Luxury?" building on the reaction to the campaign. The data converges: 70% of consumers report discomfort with fully AI-generated creative content (Variety, 2025). 39% of Gen Z — the central luxury cohort of tomorrow — have a negative sentiment toward AI ads, nearly double that of Millennials (IAB, March 2026). Gucci experienced it in February (the "Primavera" campaign marked "Created with AI" — immediate backlash). Prada may have avoided the label. It did not avoid the suspicion. Same result.

DEEP DIVE
Before the Storefront
Stendhal described it in 1822 in On Love: crystallization. A dead branch plunged into the salt mines of Salzburg emerges covered in crystals. Every imperfection in the wood is coated. This is how desire forms around an object: not in its presence, but in its absence. In the waiting. In the imagination of the not-yet-possessor.
Luxury houses are machines built to manufacture that waiting. The campaign that makes you dream without showing the price. The window display that stops you without forcing entry. The advisor who slows the transaction to intensify the desire. Every obstacle is an additional layer of crystals. Friction is not a flaw in the journey. It is the product.
There now exists a space between the client's intent and the house's storefront. A space the houses did not build, do not control, and where their future clients are spending more and more time. Call it the Antechamber.
Where desire now forms
In the Antechamber, preferences form before the visit. Comparisons happen without the brand. Decisions are made — or nearly — before the house has had a chance to seduce. The numbers give the measure: 84 million shopping queries per week on ChatGPT in the United States (Modern Retail / Stackline, March 2026). 700 million weekly active users worldwide (eMarketer). Two-thirds of Gen Z buyers now use an LLM (Large Language Model) to research products before purchasing (Harvard Business Review, 2026). And this data is often inaccurate — which makes the problem worse: the house is not merely absent from the Antechamber, it is potentially misrepresented there.
Jing Daily documented it on March 20: "AI-powered systems are making purchasing decisions before consumers ever browse — and brands that fail to adapt risk being misread, not just overlooked." The risk is not invisibility. It is distortion.
McKinsey, in "Europe's Agentic Commerce Moment" (March 2026), details the mechanics: discovery is now the phase where preferences form and winners emerge. Agent usage declines as you approach the transaction — the final purchase remains human, the desire no longer entirely so. The decisive moment has shifted upstream. And OpenAI confirmed it at its own expense on March 24 by withdrawing Instant Checkout: the locus of power is not the register. It is the recommendation that precedes it.
Baudrillard anticipated it in Simulacra and Simulation (1981): the sign can precede and replace the reality it was supposed to represent. This is exactly what is happening in the Antechamber. The AI agent's response is not a path to the house — it is, for that client at that moment, the house itself. A house whose words it did not choose.
Steve Jobs put it differently: "People don't know what they want until you show it to them. (...) Our task is to read things that are not yet on the page." Luxury houses have been doing this for centuries — reading what is not yet written, anticipating desire. The difference: they did it in the storefront, in the salesperson's gesture, in the silence of the showroom. The AI agent does it in the Antechamber — and it does it before them.
This is not a crisis of desirability. It is a crisis of the geography of desire.

Being cited is no longer enough
Converteo measured ten houses on ChatGPT and Gemini in March 2026 — accounting for 86% of the global AI audience — across five dimensions: visibility, narrative fidelity, factual accuracy, actionability, source quality (GEO Benchmark 2026, full downloadable report). Result: luxury house visibility in LLMs is still heavily tied to their financial valuation, their heritage, and their media capital — rather than the relevance of their current offerings.
Actionability — the ability of AI responses to convert into a visit or a purchase — is the lowest score for every house (39-52/100). The best-represented owe it to 150 years of writings, reviews, and digitized archives feeding the language models. This is not a strategy. It is a rent.
Bourdieu would say the great houses were living off symbolic capital accumulated over a century and a half. This capital precedes them — it belongs to them no more than an inheritance belongs to the one who receives it. And capital that is not actively maintained — in the vocabulary of the models, in the quality of agent-readable data, in actionability — erodes. Silently.
The data confirms this from other angles. Avenue Z and Profound now measure "Citation Share" — a brand's share of voice in LLM responses — and find that roughly 10% of referral traffic for fashion brands already comes from conversational AI engines (Avenue Z / Profound, March 2026). Relevance Digital notes that UHNW (Ultra High Net Worth) consumers adopt AI search at twice the average rate (Relevance Digital, March 2026). Gartner forecasts a -25% drop in traditional search engine query volume by the end of 2026. Traffic is migrating. And the houses that have not built a presence in the Antechamber will not even see it leave.
Being cited in the Antechamber is not enough. You must be actionable there. And on that front, no one has an answer yet.

Two doors, one hallway
Sephora enters ChatGPT through beauty — LVMH's most data-rich vertical, the least risky to test. Kering appoints a CDO whose roadmap explicitly mentions agents. Two groups, two moves, same reading of the problem: the Antechamber exists, and you need to be in it.
The infrastructure follows. Gap installs checkout inside Google Gemini via the Universal Commerce Protocol, without redirect — Google Pay, AI sizing by Bold Metrics. Sven Gerjets, CTO of Gap: "It's no longer the keyword, it's the conversation." (CNBC, March 24). Accenture invests in DaVinci Commerce and introduces the concept of "Agentic BrandStore": conversational brand experiences governed inside the LLMs themselves (Accenture, March 23). At DFS (LVMH travel retail), Rezolve AI reports +10% conversion and +50% search revenue via its agentic engine (Globe Newswire, March 19). Soumia Hadjali, at Louis Vuitton, sums it up: "Agentic commerce is about being where [customers] are and being relevant at the right moment."
What distinguishes the two approaches at the top: Sephora enters the external agent. Kering, via Balenciaga × Intelo.ai, builds internal agents to optimize merchandising. Neither answer is yet that of the heart of luxury — jewelry, high-end fashion, leather goods. Deloitte Digital quantifies it (March 2026): roughly 40% of houses are still evaluating how to deploy AI, 41% have begun implementing it in selected areas, and fewer than 12% integrate it into their core functions. The "permanent pilot" remains the dominant mode in the sector.
These houses are watching. They are right to take their time. They are wrong to believe they have it.

The asymmetry of attention
Everything above is infrastructure. What follows is about the bond.
Luxury rests on a double gap in attention. The first is an asymmetry: the house chooses who receives its gaze, the client does not — they aspire. The second is an asynchrony: desire is born in the client long before the house returns it. The client desires, waits, qualifies themselves; the house observes, evaluates, and responds only at the moment it has chosen. The waitlist is not an operational accident — it is the institutionalized form of this asynchrony. Stendhal called it crystallization: desire thickens in the temporal gap between the craving and the object. The houses that open the door to the AI agent introduce into this relationship an intermediary that abolishes both gaps at once. The agent is symmetric: it gives anyone the information the house reserved for the client who had crossed the threshold. And it is synchronous: it answers in three seconds. The time that manufactured desire — the time the house had instrumentalized for two centuries — disappears.
Capgemini, in "From Hype to How" (February 2026), poses a figure that should temper enthusiasm: only 8% of consumers would pay for an autonomous AI shopping agent. Meanwhile, 74% say they value human interaction in-store. The luxury client does not demand fluidity. They demand consideration. Daniel Langer puts it another way: "In a world where machine intelligence is abundant, how do you build a brand that is worth more because it is irreducibly human?"
Still, the projections are there. Bain, via The Fashion Law, estimates that 15 to 25% of US e-commerce sales will pass through AI agents by 2030 — that is $300 to $500 billion (The Fashion Law, March 2026). Morgan Stanley projects 50% of online purchases via agents at the same horizon. 30 to 45% of US consumers already use GenAI (generative AI) for product research. The trend is not reversing.
I am convinced that the houses that master the Antechamber will not be those that opened the widest door. They will be those that learned to control what happens in the hallway — by deciding which data the agent can read, which narratives it can tell, and which thresholds it may not cross. Friction has not disappeared. It has changed form. The question for every house is now: are you eliminating it, or redefining it?

THE STORY
Dior × Kahoona: reading before speaking
The problem: 96% of visitors lost
Franck Le Moal, CDO and CTO of LVMH, described it on the Google Cloud Blog: the group built with Google Cloud a centralized data and AI platform aggregating data from its 75 houses. 40,000 monthly users of internal AI systems. 1.5 million GenAI queries across departments (Google Cloud Blog). The Arnault family, via Aglaé Ventures, invested over $300 million in AI startups in 2024 alone (Forbes, March 24, 2026).
But infrastructure does not solve a fundamental problem: 96% of visitors to a luxury website remain anonymous. No cookie. No login. No declared data. Classic personalization tools only see the 4% who identified themselves. For the rest — those who arrive, look, hesitate, and leave — the house is blind. This is the "cold-start problem" of luxury e-commerce: personalizing for a visitor you know nothing about.
The method: "digital body language"
Gal Rapoport was among the first Amazon employees in Israel. He then led the AI and Personalization teams for Alexa Shopping. He knows exactly what happens in the Antechamber — he helped build it. In 2021, he co-founded Kahoona with Alon Ashkenasi and Ohad Tzur, all three graduates of the Technion and MIT. Headquarters in San Diego, R&D in Tel Aviv. $4.5 million seed led by Global Founders Capital, with angels from Amazon, NBC Universal, Verizon, and SAP (PRNewswire).
Kahoona's thesis: if the external agent captures intent before the visit, the house can still capture intent within the first seconds on its own site — before the visitor has said a thing. The method is called "digital body language." The scroll speed on a product page. The pinch-to-zoom speed on an image. Swipe patterns. The exact zones where the finger touches a mobile screen. How long each product is viewed. The product the visitor zooms into — and the one they skip. Kahoona reads these micro-signals in real time, without third-party cookies, without fingerprinting, without personally identifiable data (GDPR, CCPA, SOC 2 certified), and reconfigures product listing pages for each detected profile. 15x more behavioral data points than traditional tools. 83% announced predictive accuracy. 91% audience coverage.
In practice: if an anonymous visitor shows interest in watches, watch pieces move to the top of the page. If they hesitate between two categories, the page rearranges to reflect that hesitation. The system creates predictive segments in real time — high-intent buyers, bargain hunters, gift shoppers, novelty seekers — from the very first interaction, without waiting for the client to log in. This is not personalization in the CRM sense. It is intent reading at the exact moment it forms.
+24% clicks, zero cookies
In June 2025, Antoine Arnault — Bernard Arnault being retained by his new diplomatic functions — presents Kahoona with the Best Business Prize at the LVMH Innovation Award, at VivaTech. Trophies by Tiffany & Co. Three winners out of fifteen finalists. The group: "Took personalized customer experience to an unprecedented level." (FashionUnited, June 2025).
The documented results on a case identified as a "Global Luxury Fashion Leader" — linked to Dior by the press through the VivaTech prize: +24.2% click-through rate on product listing pages. +19.1% pages visited per session. +12.8% average order value. 96% of anonymous visitors — normally lost — activated (Kahoona case study). LVMH plans to extend the solution via its Maison des Startups program — test in one house, deployment across the 75+.
There is a clear symmetry in what LVMH does this week: Sephora enters the external agent to meet intent where the client already is. Dior builds intelligence internally to capture intent the moment the client arrives. Two answers to the same problem, at two different stages of the Antechamber. One tells the client: "I come to you." The other says: "I read you the moment you arrive." Neither says: "I'll wait for you."
The Compass:
- Are your product pages optimized for the 96% of anonymous visitors who never log in?
- Is your loyalty program designed to talk to an LLM, or only to send emails?
- Your internal AI agent knows your existing clients. What does it know about the client who has never visited you?

MY INDISCREET QUESTION
Prada did not say "we used AI." It did not say "we didn't use it" either — not immediately. The denial came a week later, on Instagram, and it resolved nothing.
70% of consumers report discomfort with fully AI-generated creative content (Variety). This is not a question of actual usage — it is a question of suspicion. Suspicion alone is enough to degrade perception. Gucci displayed it and was sanctioned. Prada did not display it and was still suspected.
Furthermore, the EU AI Act (Article 50) takes effect on August 2, 2026: all AI-generated content will have to be marked — watermarks, metadata, technical identification. Fine: 15 million euros or 3% of global revenue (Charles Russell Speechlys, March 2026). Silence will no longer be a legal option.
My question: in your executive committees, who is responsible for deciding not whether you use AI in creative work, but how you talk about it? And if no one is — who should be, before the law decides for you?
ON MY READING LIST
McKinsey — "Europe's Agentic Commerce Moment" (March 2026)
The study documenting the decisional shift. With the six-level automation curve and the confirmation that luxury plateaus at level 2: the agent recommends, the human decides. The delegation ceiling is not technical. It is emotional. And it holds — for now.
Converteo — "Luxury in the Age of AI Search 2026"
The first benchmark of house visibility in AI engines. The actionability score (39-52/100) is the most revealing and most uncomfortable finding of the study. Gartner: -25% in traditional search traffic by end of 2026.
Business of Fashion — "Is AI Antithetical to Luxury?" (March 25, 2026)
The question no one wanted to ask publicly. Triggered by Prada × Wolfson. The answer, according to BoF: not necessarily — but the suspicion is, itself, incompatible with luxury.
Capgemini — "From Hype to How" (February 2026)
The necessary counterpoint to the "everyone is pivoting" narrative. 8% would pay for an AI shopping agent. 74% value human interaction in-store. 76% want clear rules. The reminder that the consumer is not as far along as the tech industry believes.
1.4 billion proprietary data points (185 brands, 64 markets) connected directly into ChatGPT, Claude, Copilot, and Gemini Enterprise via the Model Context Protocol. Existing in the Antechamber without going through the open merchant protocol. An alternative infrastructure for houses that refuse the ACP (Agentic Commerce Protocol) but can no longer afford absence.
COMING NEXT
Watches & Wonders Geneva opens on April 14. Watchmaking and agentic AI: an encounter the sector has been postponing for three years — and one that the 15 tech startups selected for the program (VersAI, RecoWatch, Virtuality) will no longer allow it to postpone. On April 16, Kering presents its strategy at the Capital Markets Day. Pierre Houlès will deliver there the first arbitration between the patience of luxury and the urgency of the Antechamber. The most difficult arbitration there is, when you know that patience is the promise and urgency the threat.
Luxe oblige.
