Retail Just Had Its Best Q4 in Years. Amazon Sellers Should Act Like It.

Retail Q4 2025 Was Strong — Amazon Sellers Should Invest Accordingly — Astra Blog

The Numbers Don't Match the Noise

If you've spent any time on LinkedIn lately, you'd think Amazon selling was under siege — tariffs destroying margins, AI dismantling search, fee hikes squeezing everyone out. Then the Q4 2025 earnings reports came in.

Across the 22 retailers in the S&P 500 that had reported by late February, total earnings were up 6.9% year over year on 8.6% higher revenues. More than three-quarters beat revenue estimates. Off-price chains dominated: Ross Stores more than doubled its same-store sales forecast with a 9% jump. Dollar Tree climbed 5%. Walmart's US e-commerce grew 27% — its 15th straight quarter of double-digit online growth.

US Census Bureau data confirmed it from the e-commerce side: Q4 online retail hit $316.1 billion, up 5.6% year over year. E-commerce now accounts for 18.3% of total retail sales, and full-year 2025 e-commerce came in at $1.23 trillion, up 5.4% from 2024. The National Retail Federation is projecting another 4.4% growth in total retail sales for 2026, targeting $5.6 trillion.

Consumers are stretched. Budgets are tight. But people are still buying — just smarter. They're prioritizing value and gravitating toward platforms that offer convenience and competitive pricing. That should sound familiar to anyone selling on Amazon.

Amazon's Q4 and What It Means for Your Business

Amazon posted $213.4 billion in Q4 revenue, up 14% year over year. Full-year revenue hit $716.9 billion. But the numbers that matter most for sellers are more specific.

Third-party seller services revenue reached $52.8 billion in Q4, up 11% year over year. Paid units grew 12% globally — the highest quarterly growth rate of the year. Amazon's advertising business hit $21.3 billion in Q4, up 22%. And third-party sellers now account for 61% of all paid units on the platform.

More than six out of every ten products sold on Amazon are sold by independent sellers — not Amazon retail, not first-party inventory. The platform's growth is increasingly driven by the marketplace, and that's you.

Amazon delivered 13 billion items same-day or next-day globally in 2025, up 44% from the prior year. The fulfillment infrastructure that supports third-party sellers is getting better. It's also getting more expensive. But the demand side of the equation is holding up.

Naming the Anxiety Running Through Seller Communities

There's a specific kind of dread circulating right now. Between AI shopping assistants, tariff uncertainty, rising FBA fees, and the constant "everything is changing" drumbeat, it's easy to convince yourself the business is deteriorating.

The Q4 data says otherwise.

Consumers haven't stopped buying on Amazon. They're buying more. Amazon added $12 billion in incremental advertising revenue in 2025 alone — that only happens if brands are seeing returns on that spend. Paid unit growth of 12% means more transactions are happening, not fewer.

None of this means the business is easy. Rising FBA fees, increasing ad costs, and tariff-driven supply chain shifts are real pressures. But there's a meaningful difference between "this is getting harder" and "this is going away." The Q4 data confirms it's the former.

AI Shopping Is Real — Just Not Yet

You've probably read that AI is about to replace how people shop. ChatGPT launched ads. Google has AI Mode. Amazon has Rufus. The narrative is that AI agents will soon buy products for consumers, bypassing listings, ads, and search entirely.

That's a trend worth tracking. But Q4 shows exactly how early we are. Amazon's paid units grew 12%. Advertising revenue grew 22%. E-commerce's share of total retail grew again. If AI were meaningfully disrupting how people buy right now, you wouldn't see those numbers.

The transaction is still happening on Amazon — through search, through ads, through product pages. The infrastructure you've built your business on isn't disappearing. It's evolving. Sellers who adapt their listings and ad strategies for AI-influenced discovery will be better positioned when the shift accelerates. But the shift hasn't replaced the fundamentals yet.

🚨 What the narrative says

• AI will bypass Amazon search entirely
• Ad spend ROI is collapsing
• Fee hikes signal platform decline
• Tariffs will destroy margins permanently

📊 What Q4 data actually shows

• Paid units up 12% — transactions accelerating
• Ad revenue up 22% — brands are investing more
• 3P sellers drive 61% of all units sold
• NRF projecting 4.4% growth in 2026

What to Do With This Information

The macro data doesn't support pulling back on ad spend. Paid units are up, conversion is holding, and advertising revenue growth means brands are investing more, not less. If your competitors are scared and retreating, that's a window for you.

1. 1 Start Q2 planning now. Consumer spending is resilient heading into 2026. Review your inventory levels, finalize your promotional calendar, and confirm you're positioned for spring and summer selling seasons before your competitors do.
2. 2 Optimize for the value-seeking consumer. The clearest pattern in Q4 was that value wins. Ross Stores, Dollar Tree, Walmart — all grew by offering better value at the right price. If your listing doesn't communicate value clearly through pricing, bundling, or messaging, you're leaving money on the table.
3. 3 Treat fee increases as a margin problem, not an existential threat. FBA fees went up $0.08 per unit in January. Ad costs continue to rise. These compress margins — but on a business that just posted record Q4 volumes. Tighten ad efficiency and unit economics. Don't question whether the business is worth being in.
4. 4 Don't wait on AI readiness. AI-influenced discovery is coming, but Q4 shows the fundamentals still dominate. Use the runway to optimize listing copy, A+ content, and keyword strategies for both traditional and AI-assisted search — before it becomes urgent.

The data is in. People are still buying. E-commerce is still growing. Amazon's marketplace is still the largest and most active selling platform in the world. The sellers who internalize that and invest accordingly will outperform the ones who let the noise convince them otherwise.
