The Reading

Nike's Preference Gap is 63 points. Culturally, Nike is named in 91 percent of running conversations and chosen in 28 percent. Seen almost everywhere, chosen roughly one time in four. AI answers return that gap cleanly.

Presence Rate is the share of mention-query observations where the brand appears. Preference Rate is the share of recommendation-query observations where the brand lands top-three. The gap is the difference, in percentage points. On 19 April 2026, across five AI systems, that gap is 63.

Nike is not missing from the conversation. Nike is passed over inside it.

The inverse of the Oatly reading. Oatly is culturally legible at the wrong altitude. Nike is culturally present everywhere, and the recommendation goes to the specialist. Brooks. ASICS. Hoka. Saucony.

How We Read It

Five AI systems, 19 April 2026, fresh sessions, no personalization.

ChatGPT, Perplexity, Gemini, Copilot, Claude. Two queries carry the reading: a mention query, "what are the major athletic-footwear brands," and a recommendation query, "I am looking to buy running shoes, what should I get." Three runs each, aggregated, split into the two rates.

Presence Rate, 91 percent. Preference Rate, 28 percent. The gap is the measurement the brand has to live with.

Presence Rate
91%
Mention query, "what are the major athletic-footwear brands." Nike is named in nearly every answer across the five systems. The brand's institutional footprint is intact.
Preference Rate
28%
Recommendation query, "what running shoes should I buy." Nike lands top-three in roughly one in four answers. Specialist brands take the slots Nike used to own by default.

Both numbers live inside the same systems on the same day. What changes is the question. Awareness questions pull from press and cultural reference, where Nike's density is structural. Recommendation questions pull from taste tests, runner-community sentiment, and specialty-retail reviews, where the specialists have compounded editorial weight for years.

Mention and recommendation are two different cultural registers. The gap between them is the finding.

What the Five Systems Return

The shortlist below is what the five systems, aggregated, treat as the recommendation set. Specific products, dated to their release cycle. Nike appears. Nike rarely leads.

  2. 02
    ASICS Novablast 5

    Nike Vaporfly 4

  6. ···
    Nike, daily trainer slot
    Vomero 18 named as "reliable classic," not default

Nike owns two slots in the recommendation layer. Racing, where the Vaporfly 4 and Alphafly 3 carry weight across ChatGPT, Gemini, and Perplexity. Basketball, where Gemini names Nike as "the standard." Outside those two, the recommendation set is a specialist set. Each of those brands has a named product the five systems return in consensus. Nike has two, both category specialists, neither the brand's everyday-runner line.

04

System by System

The gap is not uniform. Each of the five systems returns Nike a little differently. The Preference Gap averages across them, but the shape of the gap tells the operational story.

ChatGPT. Nike Pegasus 41 is the default "one-shoe-for-everything" trainer at category boundary. The most Nike-favourable system in the set, and even here Nike does not sweep the recommendation slots.

Gemini. Alphafly 3 and Vaporfly 4 carry the racing slot. Vomero 18 is "reliable classic" for daily runs, second to the ASICS Novablast 5. For basketball, Gemini names Nike first.

Perplexity. The hardest system on the brand. Nike appears only in racing (Vaporfly 4) and long runs (Vomero Plus). Everyday training goes to the ASICS Megablast and Adidas Adizero Evo SL. Beginners go to the Brooks Ghost 17.

Copilot. Nike appears once, in trail running, with the Ultrafly as second option behind Salomon. The daily-trainer slot goes elsewhere. The sparsest Nike presence in the set.

Claude. Sits between Gemini and Perplexity, pulling Nike for specialist uses and specialist brands for everyday mileage.

Nike holds where the racing layer is dense. Nike thins where the everyday-runner layer is owned by specialists.

05

Two Readings, One Mechanism

Two different metrics on the same mechanism. Retrieval rewards the altitude where editorial consensus is densest. What counts as consensus differs by category.

Oatly · Analysis 001
Representation Gap · 0.93
The brand's current thesis is a functional-drinks argument. AI returns "oat milk" in forty-two of forty-five observations. Visible at the narrow altitude, absent at the altitude buyers start from.
Nike · Analysis 002
Preference Gap · 63pp
Presence Rate 91 percent. Preference Rate 28 percent. The brand is seen almost everywhere and chosen roughly one time in four. Specialists own the recommendation slot the brand used to own by default.

A brand is culturally legible at the altitude where its primary editorial corroboration lives. Oatly's corroboration sits at an altitude the culture, and therefore AI, does not reach. Nike's product corroboration has shifted to specialists and the recommendation slot followed. Neither finding is a verdict. Both are dated readings a reader can re-run.

Representation Gap measures where. Preference Gap measures what is chosen. Different readings, same retrieval layer.

The four specialist products above carry the recommendation slot Nike used to own by default. The specific models matter, because the recommendation layer answers at the product level, not the brand level.

A 63-point gap between mention and recommendation is large enough to run a strategy against. It is specific enough to move.

What the Reading Can Carry

Preference Gap 63 points, 19 April 2026, five AI systems.

The number is the diagnosis, not the strategy. What it forecloses is the sentence "awareness is strong, the rest will follow." Preference in retrieval does not follow awareness. It follows product-level corroboration at the recommendation altitude, currently owned by the Brooks Ghost 17, the ASICS Novablast 5, the Hoka Clifton 10, and the Saucony Endorphin Speed 5.

Nike has two products the five systems cite with conviction, the Vaporfly 4 and, to a lesser extent, the Vomero 18. Closing the gap is product-level work, compounded across runner communities, specialty retail, and category-specific review outlets. The awareness is already at 91 percent.

Awareness is not the input. Recommendation-altitude corroboration is the input. The gap between the two is the number.

Preference Gap 63 points. A dated reading on a dated brand, argued with a published protocol.

Mention and recommendation are two different cultural registers. The gap between them is measurable, movable, and specific. This reading is one of those measurements. The next will run against the fall-winter 2026 product cycle, with the same method, the same systems, and the same number format, so the movement is inspectable.
