Pfizer scores 53.0 out of 100 on the Fameproof index, ranking 36 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 57.0 while Gemini scores it 49.0, a gap of 8.0 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 Pfizer in 55% of answers and places it early enough to score 38% on prominence; Gemini names it in 44%.

Across the 24-prompt panel there are 2 prompts where at least one model does not name Pfizer at all — those are the answers a competitor is winning instead, and the table below shows which.

Measured inside pharmaceuticals rather than the wide healthcare pool, Pfizer scores 86.5 — the fairer question for a buyer already shopping that market, though it cannot be compared across markets.
