What the numbers say

Merck scores 41.0 out of 100 on the Fameproof index, ranking 52 of 186 companies measured in the run of 26 October 2026. The index is the mean of the per-model scores below.

Visibility is uneven across models: Gemini scores it 44.0 while ChatGPT scores it 39.0, 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.

Gemini names Merck in 42% of answers and places it early enough to score 16% on prominence; ChatGPT names it in 29%.

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

Measured inside pharmaceuticals rather than the wide healthcare pool, Merck scores 75.7 — the fairer question for a buyer already shopping that market, though it cannot be compared across markets.
