Amazon reported its Q4 2025 results on 5 February, and for anyone operating in the Amazon advertising ecosystem, one number stands out. 

Advertising revenue reached $21.3 bn for the quarter, up 23% year-on-year, adding $12bn in incremental advertising revenue across the full year. At that scale, Amazon Ads sits alongside Google and Meta as one of the most strategically significant performance media platforms in the world.

The headline growth figure is striking. But the more important signal for brands is what the results reveal about how the Amazon environment is changing around them.

Organic visibility is increasingly paid-driven

The relationship between advertising investment and organic rank on Amazon has always existed in some form. What we are now seeing across client accounts is that relationship tightening considerably. Media investment, sales velocity and organic ranking are operating as a single flywheel rather than three separate levers.

The practical implication is significant. A brand that pulls back on advertising to manage short-term costs does not simply lose ad-driven sales. It risks a decline in sales velocity that feeds through to organic rank, which then reduces visibility to the shopper who was never going to click on an ad. Advertising and organic are no longer separate strategies that happen to coexist on the same platform. They are a single system.

The Q4 results reflect brands responding to this reality at scale. The 23% growth in advertising revenue is not simply more brands entering the platform. It is existing brands investing more deeply because they understand that advertising investment is also an investment in organic position.

Retail media maturity is here

Amazon is not a marketplace that happens to carry advertising. It is a full-funnel media environment in which awareness, consideration, conversion and loyalty can all be managed within a single ecosystem.

The Q4 data reinforces this. Prime Video's ad-supported tier now reaches an average audience of 315 million people across 16 countries. New AI-powered tools including an ads agent and creative agent are compressing the time required to build and optimise full-funnel campaigns from weeks to hours. Amazon Marketing Cloud continues to evolve its measurement capabilities, connecting top-of-funnel exposure to purchase outcomes with increasing precision.

These are not features of a retail platform with advertising bolted on. They are the infrastructure of a mature media business. The brands treating them as such are operating in a fundamentally different competitive position to those that continue to approach Amazon as an e-commerce channel with a Sponsored Products line item.

Strategy is replacing tactics

The third shift visible in the Q4 results is harder to quantify but arguably the most consequential for brands. The accounts outperforming right now are not the ones with the most optimised individual campaigns. They are the ones with category-level growth plans that treat Amazon as a core media channel with its own audience strategy, content infrastructure and measurement framework.

The gap between brands that run Amazon ads and brands that build Amazon growth engines is widening. The former optimises bids and budgets and measures ACOS. The latter builds a view of its category, understands the full customer journey on the platform, deploys media across the funnel, and uses data from advertising activity to inform decisions that extend beyond advertising. The Q4 earnings confirm that the market is increasingly rewarding the second approach.

Amazon's announcement of $200bn in capital expenditure for 2026, predominantly directed at AWS and AI infrastructure, signals continued and accelerating investment in the capabilities that underpin advertising performance: better data, better targeting, better measurement, better creative tooling. The platform brands are investing in today will be meaningfully more powerful in 12 months.

What this means for your brand

The Q4 results are not simply evidence that Amazon advertising is growing. They signal that Amazon's business model has continued its shift toward media, and that this changes how brands need to operate inside the platform.

At Vector Retail Media, we look at Amazon from every angle: media, retail, content, data and category strategy. The earnings cycle confirms the direction of travel we have been advising clients on for the past year. The brands that will be best positioned in 2026 are the ones that start building their Amazon growth engine now rather than waiting for the gap to widen further.
