Maker or primary seller status
OpenAI states that merchant ranking considers whether you are the maker or primary seller of an item, so a reseller listing competes from behind on a factor it cannot change by editing a page.
Per-platform status
Where a platform documents relevant behavior, its status and source are shown. Undocumented platforms show "unknown" - honest unknowns, never invented.

How to act on this
If you make the product, make that legible: brand ownership, manufacturer identity and an authoritative product page carrying the canonical identifiers. If you resell, accept that this factor runs against you and compete on the ones you do control, which on the same stated list are availability, price and quality.
