Amazon has secured the top position for marketplace visibility on generative AI platforms, accounting for 19.3% of the total share of voice. The ranking is based on the frequency and prominence of mentions within AI-generated responses.
Why it matters
Brand visibility within generative AI is increasingly driven by a company's total volume of traditional media coverage. This shift suggests that companies with higher media presence are more likely to be prioritized by AI discovery tools.
Amazon leads with a 19.3% share of voice and a 92% average prominence score, while Walmart holds 14% share of voice with an 84% prominence score. Other major players include Alibaba at 12.6%, Shopify at 11.6%, and eBay at 11.1%.

The details

Timeline

Roadmap
As AI integration into search becomes standard, companies are fighting to maintain digital real estate in machine-generated results. This study follows the trend where established tech and retail giants leverage massive traditional media footprints to dominate the AI discovery landscape.
Users can expect AI-generated shopping recommendations to prioritize retailers with higher traditional media visibility. This may streamline product discovery while potentially limiting the range of smaller, lesser-known brands in AI responses.
The takeaway
Retailers must now consider their traditional media footprint as a primary factor in their long-term digital discovery strategy. Consumers should remain aware that AI-generated suggestions are heavily influenced by existing brand prominence in the media.
