Example Questions

• "Who are the top players in [category]?"
• "Is [category] growing, and how fast?"
• "What does the 1P vs. 3P mix look like in [category]?"
• "Size [category] and break it down by sub-category, which slice is growing fastest and would be the best entry point for a new SKU?"
• "Compare category size and growth rate for [category A] vs [category B] and tell me which is the better long-term bet."
• "What’s the TAM for [category], and how much of it is currently controlled by the top 3 brands vs. fragmented across smaller sellers?"

Frequently Asked Questions

What counts toward "category size"?

It includes total revenue, unit volume, and the count of active brands and products within the category as defined on Amazon, not just top-line sales for a handful of leaders.

Can this size a brand-new product concept that doesn't have a category yet?

Yes. You can size the closest existing category as a proxy, or size a narrower niche within it, to estimate opportunity before a concept exists.

How current is the growth rate?

Growth is typically shown year-over-year using the most recent trailing period available, so it reflects recent momentum rather than a single snapshot in time.
