eBay scores 17.0 out of 100 on the Fameproof index, ranking 72 of 120 companies measured in the run of 5 August 2026. The index is the mean of the per-model scores below.

Visibility is uneven across models: ChatGPT scores it 19.0 while Gemini scores it 15.0, a gap of 4.0 points. A brand that is strong on one model and weak on another has a different problem from one that is mid-table everywhere.

ChatGPT names eBay in 6% of answers and places it early enough to score 1% on prominence; Gemini names it in 6%.

Across the 24-prompt panel there are 5 prompts where at least one model does not name eBay at all — those are the answers a competitor is winning instead, and the table below shows which.

Measured inside e-commerce rather than the wide retail pool, eBay scores 74.0 — the fairer question for a buyer already shopping that market, though it cannot be compared across markets.
