The Maze: Amazon has quietly rewritten the rules of CPG competition. Using 2025 US marketplace data, the visuals show who really wins when shoppers search, compare and buy. The answer is not who spends most on brand but who executes best inside Amazon’s system.

  • Emergent brands control majority sales in 16 of 18 CPG categories, peaking at 93% in health care and 87% in pet health, leaving incumbents dominant only in cat and dog food

  • Third party sellers account for the bulk of challenger sales, often exceeding 60% share in categories like snacks, household supplies and baby care

  • Non branded search drives discovery, reaching 97% in pantry staples and over 90% in health care, making brand recall optional rather than required

Why it matters: Amazon is not a digital shelf, it is a demand engine. Brands that fail to win generic queries lose relevance, margin and negotiating power. Ecommerce growth now belongs to those who optimize algorithms, not those who rely on awareness.

🚀 Emergent Brands

Challengers dominate Amazon CPG sales

Emergent brands now own most of Amazon’s CPG economy. Across categories, they consistently outpace major brands by winning on speed, pricing and operational execution rather than heritage or advertising muscle.

• Challenger brands hold 93% share in health care and 84% in pantry staples, showing Amazon favors fast iteration and competitive pricing over brand trust
• Beauty and personal care see 63% to 70% challenger share, driven by influencer led discovery and rapid SKU refresh cycles
• Only cat food at 61% major brand share and dog food at 53% remain brand led, reflecting habit, risk aversion and repeat purchase behavior

The pattern is clear. Where switching costs are low, brands lose power. Where risk is high, incumbents still matter. That boundary defines Amazon’s new CPG map.

🤝 Who Really Sells

Third party sellers power challenger growth

Behind challenger dominance sits a less visible force: third party sellers. They are the operational backbone of Amazon’s long tail, scaling faster than both private labels and legacy brands.

• Third party sellers exceed 60% of challenger sales in snacks, pet health and men grooming, reflecting superior pricing agility and faster response to demand spikes
• Small independent brands dominate nutrition bars at 53% and cat food at 58%, showing niches reward focus more than scale
• Amazon private labels remain under 20% in most categories, growing selectively but constrained by trust, assortment breadth and regulatory pressure

Amazon did not kill brands. It disintermediated them. Sellers who master logistics, ads and reviews now act as the new brand layer.

🏭 CPG vs Sellers

Third parties lead most categories

Legacy CPG brands still sell billions on Amazon, but they increasingly play defense. In most categories, third party sellers now take the lead.

• Third party sellers exceed 80% share in health care and pet health, exposing the limits of offline brand equity online
• Baby care and skin care show 66% and 63% third party share, reflecting faster innovation cycles than multinational portfolios allow
• Only nutrition bars, paper and plastic, and oral care remain competitive battlegrounds rather than clear losses for incumbents

Scale alone no longer protects market share. Execution speed, data feedback and ad efficiency decide winners inside Amazon.

🔍 Search Reality

Generic search rules Amazon

Amazon shopping starts with problems, not brands. The search split reveals how demand is created and why challengers win.

• Non branded search hits 97% in pantry staples and 92% in health care, forcing brands to compete on relevance, not recognition
• Beauty and personal care average 73% non branded search, despite heavy brand marketing outside Amazon
• Cat food stands out with 54% branded search, proving loyalty survives only where consequences of switching feel real

Amazon has trained shoppers to trust the system, not the logo. Winning search means winning the algorithm, not the mindshare.
