The ChatGPT Shelf for Olive Oil

The names you know aren't the ones ChatGPT names

California Olive Ranch leads at 59%, then two brands most people couldn't place — Terra Delyssa 52%, Cobram Estate 48%. Filippo Berio and the other grocery-aisle staples don't crack the top ten. 259 brands showed up across 1,177 questions. And this is the strongest brand-direct shelf of all eight categories: 12% of offers came straight from the producer, not a retailer.

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 olive oil.

  1. 1 California Olive Ranch 59%
  2. 2 Terra Delyssa 52%
  3. 3 Cobram Estate 48%
  4. 4 Partanna 39%
  5. 5 Kosterina 28%
  6. 6 Graza 14%
  7. 7 Pompeian 12%
  8. 8 Castillo de Canena 12%
  9. 9 La Tourangelle 9%
  10. 10 Atlas Olive Oils 8%

Where the offers come from

Every product ChatGPT showed came from somewhere. Brand-direct means the offer pointed at the brand's own store rather than a retailer.

  • Brand-direct 12% · 330 offers
  • Sam's Club 4% · 124 offers

How we measured this

  • We asked ChatGPT 1,177 shopping questions about olive oil 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 1,177 of them.
  • We recorded every brand mentioned and every product offer shown, 3,803 offers across 259 brands.
  • This is one engine, one country, one point in time. It is a snapshot of a shelf that moves.
