Who ChatGPT names

Share of shelf is the percentage of answers a brand appeared in. It is not a rank of quality or sales — it is how often the model brought the brand up when someone asked about at-home gel nails.

  1. 1 Olive & June 51%
  2. 2 OPI 33%
  3. 3 Sally Hansen 31%
  4. 4 Essie 23%
  5. 5 Gelish 15%
  6. 6 Modelones 13%
  7. 7 Le Mini Macaron 13%
  8. 8 KISS 13%

How we measured this

  • We asked ChatGPT 627 shopping questions about at-home gel nails in July 2026. The questions never named a brand, so nothing here was prompted into the answer.
  • Questions were repeated. ChatGPT does not answer the same way twice, so a single ask tells you nothing — share of shelf is the pattern across all 627 of them.
  • We recorded every brand mentioned and every product offer shown, 3,371 offers across 179 brands.
  • This is one engine, one country, one point in time. It is a snapshot of a shelf that moves.
