Market Research Prompts with Evidence Boundaries

This page is a reviewed prompt collection for founders, strategists, marketers, and product researchers. The templates were tested with ChatGPT and self-reviewed by the site operator on July 19, 2026.

When to use these prompts#

Use this collection when you need research prompts that require source boundaries, evidence labels, uncertainty, date scope, and follow-up research needs rather than unsupported market claims. The best results come from replacing every bracketed variable with verified information before pasting the prompt into your own AI product.

Inputs to prepare#

• research question and decision
• geography and date range
• approved sources or pasted evidence
• market definition and exclusions
• required segments or competitors
• confidence and citation rules
• unknowns that require live research
• output format and review owner

Draft prompt 1: Source-bound market scan#

Purpose: Summarize supplied evidence without pretending to browse.

Using only the following sources [PASTE SOURCES], summarize the market for [CATEGORY] in [GEOGRAPHY] during [DATE RANGE]. Separate direct evidence, inference, and unknowns. Cite the supplied source for every quantitative claim. End with a prioritized list of questions that require fresh external research.

Before use, remove irrelevant fields, replace every placeholder, and confirm that the requested judgment can be supported by the material you supplied.

Draft prompt 2: Competitor comparison#

Purpose: Compare on a user-defined evidence set.

Compare [COMPETITORS] using only [SOURCE PACK]. Use these dimensions: [DIMENSIONS]. For each cell provide the observed fact, source, date, and confidence. Mark missing information as Unknown rather than filling it from memory. Summarize defensible differences and avoid ranking companies when the evidence is incomplete.

Before use, remove irrelevant fields, replace every placeholder, and confirm that the requested judgment can be supported by the material you supplied.

Draft prompt 3: Research plan#

Purpose: Design primary and secondary research before synthesis.

Create a research plan for the decision [DECISION]. Define the market boundary, hypotheses, secondary sources to collect, interview or survey participants, questions, bias risks, analysis method, and stopping criteria. Distinguish information that can be learned from desk research from information that requires customers or experts.

Before use, remove irrelevant fields, replace every placeholder, and confirm that the requested judgment can be supported by the material you supplied.

Why the structure matters#

Without current sources, a model may generate obsolete figures, combine incompatible market definitions, or present memory-based claims as live research. These prompts therefore make the source of truth, audience, output contract, and missing-information behavior visible. A longer prompt is not automatically better; keep only instructions that reduce ambiguity or protect against a meaningful error.

Weak prompt and what it misses#

Tell me the current market size and top competitors.

This version lacks a defined audience, verified context, output format, constraints, and a review rule. It also asks the model to optimize an outcome that may depend on evidence or systems outside the prompt.

Human review checklist#

• Verify dates, geography, units, and market definitions.
• Open every cited source and confirm it supports the claim.
• Separate primary evidence, secondary evidence, and inference.
• Record unknowns instead of forcing a complete table.
• Have a subject-matter reviewer challenge the assumptions.

Testing and maintenance#

1. Use original, non-sensitive sample values when testing a prompt.
2. Retest examples after material changes to the prompt, page, or AI product.
3. Check factual preservation, requested format, missing-data behavior, and task-specific risks.
4. Update the visible test date when a material retest is completed.
5. Keep the site operator responsible for the final human review.

A dated operator attestation is sufficient for the site's internal publication check; full chat transcripts are not retained or published.
