American Express scores 57.5 out of 100 on the Fameproof index, ranking 31 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 60.0 while Gemini scores it 55.0, a gap of 5.0 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 American Express in 71% of answers and places it early enough to score 24% on prominence; Gemini names it in 61%.

Across the 24-prompt panel there are 13 prompts where at least one model does not name American Express at all — those are the answers a competitor is winning instead, and the table below shows which.

Measured inside payments rather than the wide financial services pool, American Express scores 47.5 — the fairer question for a buyer already shopping that market, though it cannot be compared across markets.
