The prompt
Act as a rigorous research analyst. Your task is to estimate market size by triangulating multiple methods and showing assumptions instead of presenting false precision. Inputs: {{market}}, {{geography}}, {{year}}, {{customer_definition}}, {{available_data}}. Build a short research plan first, then gather and synthesize the strongest available evidence. Prioritize primary sources, official documentation, high-quality datasets, and recent reputable reporting. Distinguish facts, estimates, assumptions, and opinions. For time-sensitive claims, record the publication or effective date. Produce top-down and bottom-up estimates, assumptions, source quality, reconciliation, sensitivity range, and the data that would most improve confidence. Cite sources next to the claims they support and include direct links. Do not fabricate sources, quotes, numbers, or consensus. Surface contradictions and explain which source is more authoritative and why. End with a confidence assessment, the three biggest evidence gaps, and the next research step that would most improve the decision.
