AWS re:Invent 2025: What Amazon’s New AI Means for Amazon PPC

If selling on Amazon feels harder than it used to, you’re not imagining it.

Not because sellers suddenly forgot how to optimize listings.
Not because ads randomly stopped working.

This shift is happening because Amazon now understands seller behavior far better than it did before. And it does not need sellers to explain what is happening inside their business.

Over the past year, Amazon has expanded AI-driven automation across its core systems. Recently, that direction became more concrete.

At AWS re:Invent, Amazon announced a series of internal infrastructure upgrades focused on speed, scale, and AI-driven decisions, outlined in Amazon’s AWS re:Invent 2025 announcements. These changes increase computing power, improve model performance, and allow Amazon to process more signals in real time.

Amazon builds this kind of infrastructure when it wants algorithms to evaluate listings, ads, inventory, and compliance more consistently across the marketplace.

Amazon did not present these updates as new Seller Central features.
But Amazon now decides more quickly what gets visibility, what gets flagged, and what gets pushed down.

You will not see announcements inside Seller Central.

But you feel the impact every day.

This is not a small tweak.
Amazon is changing how its operating environment works.

Key Takeaways

• Infrastructure-first updates — AWS’s 2025 announcements focus on backend infrastructure, not direct seller-facing features.
• Tool-dependent benefits — Sellers only gain value if Amazon Ads tools intentionally apply this new infrastructure.
• AgentCore’s real role — AgentCore improves automation control and safety, not campaign strategy or decision-making.
• Graviton5 performance gains — Faster processing is enabled, but improved ROAS or lower costs are not guaranteed.
• Trainium3 potential — Better AI models emerge only if platforms train seller-specific models, not generic ones.
• Outcome-driven advantage — The real edge comes from how tools convert infrastructure into measurable outcomes, not from AWS announcements alone.

Where Sellers Are Feeling This Most

Amazon now uses automated systems to make decisions that once relied on broad rules or manual review. Sellers see this shift most clearly in a few areas.

Listings & Catalogs

Amazon no longer depends on keyword-heavy listings to understand relevance.

Its systems evaluate product context, shopper behavior, conversion patterns, and creative quality. Over time, these signals matter more than keyword density alone.

Clear, mobile-friendly listings perform better.

Overloaded and over-optimized listings often lose visibility quietly, without warnings or alerts.

Why Keyword Research Alone Is No Longer Enough

Keyword research still matters. But it no longer explains performance by itself.

Amazon now looks at what happens after a shopper clicks. It tracks engagement, scroll behavior, image interaction, and conversion consistency. These signals help Amazon judge whether a product matches buyer intent.

This explains why some listings rank for the right keywords but still struggle to maintain traffic.

Strong listings now combine:

• Clear structure

• Honest value propositions

• Clean visuals

• Accurate keyword research

When these elements align, Amazon gains confidence in the product. When they do not, exposure fades gradually.

Advertising & PPC

The same shift applies inside Amazon Ads.

Amazon evaluates ads in context. Inventory health, conversion stability, and account-level consistency now influence how campaigns perform.

This is why Amazon PPC software, Amazon PPC tools, and Amazon PPC automation platforms matter more than they used to.

Not because they guarantee better results. But because they help sellers interpret how Amazon’s systems respond.

Why Ad Spend Feels Less Predictable

Many sellers notice the same pattern: ad spend increases, but results do not scale the same way.

This is not always a bidding issue. And it is not always competition.

Amazon now evaluates ads using broader signals. It considers inventory availability, recent conversion trends, and how ads support organic visibility.

For example, Sponsored Brands campaigns often support brand recognition and search behavior before driving direct attribution. Amazon may continue testing visibility even when short-term performance looks flat.

This is why sellers sometimes see higher ad spend without immediate sales growth. Amazon may still be evaluating shopper response.

Understanding this behavior requires more than surface metrics. It requires context.

1. AgentCore: Could Amazon Ads Run With Less Manual Oversight?

AgentCore works as a rule system for AI.

It allows software tools to automate multiple steps, such as bidding, budgeting, or pausing ads, while staying within defined limits.

AgentCore does not decide strategy.
It helps tools execute strategy safely.

What AWS says

AWS describes AgentCore as a platform that lets AI agents run multi-step workflows with guardrails, memory, evaluations, and clear visibility into actions.

AWS positions AgentCore as a foundation for safer Amazon PPC automation, tighter control, and clearer explanations.

Seller-side reality

AgentCore does not automatically make Amazon PPC automation tools smarter.

Instead, it gives Amazon advertising platforms a safer structure for automation.

In practice, this means:

• Platforms can enforce stricter rules, such as inventory-aware bidding

• Sellers can see why changes occurred

• Tools can automate more steps without losing control

AgentCore does not:

• Fix attribution gaps

• Understand margins

• Create bidding strategies

• Guarantee better ROAS

Seller perspective:
AgentCore improves control and trust. Performance still depends on how well platforms design their logic.

2. Graviton5: Does Faster Infrastructure Improve PPC Results?

Graviton5 is not a seller-facing feature.

It is a faster processor that helps software handle data more efficiently behind the scenes.

Strategy stays the same.
Speed improves.

What AWS says

AWS says Graviton5 improves performance across data processing and AI workloads. This may allow faster updates and more frequent optimizations.

Seller-side reality

Sellers will not interact with Graviton5 directly.

Their Amazon advertising software will.

Here is what sellers should know:

• Backend systems may run faster

• Software pricing does not automatically drop

• Performance improvements are not guaranteed

Faster infrastructure only helps if platforms use that speed effectively.

3. Trainium3: Can AI Learn to Bid Better Over Time?

Trainium3 focuses on training AI models, not running ads.

It reduces the cost and time required to teach AI how patterns change.

What AWS says

AWS says Trainium3 makes AI model training faster and cheaper. This supports better forecasts, smarter bidding rules, and quicker learning cycles.

Seller-side reality

Trainium3 only matters if Amazon PPC software tools train models built specifically for Amazon sellers.

If they do not, nothing changes.

For example, a generic ad model does not understand inventory limits, Buy Box changes, or branded versus non-branded search behavior.

Platforms must invest in:

• Marketplace-specific bidding models

• Keyword and intent modeling

• Lifetime value prediction

• Inventory-aware forecasting

• Wasted spend detection

Without this work, Trainium3 remains unused potential.

What This Means for Day-to-Day Amazon PPC Management

Manual and reactive PPC management struggles in an environment where Amazon evaluates many signals at once.

This is where Amazon PPC automation platforms can help — when they are designed carefully.

Effective automation focuses on:

• Stability over time

• Inventory-aware decisions

• Controlled budget changes

• Clear explanations

Poor automation reacts faster without context and creates noise.

Amazon increasingly rewards consistency. Sudden swings and disconnected campaigns send mixed signals.

Sellers’ Takeaway

At the end of the day, these AWS upgrades are exciting, but sellers only benefit when tools turn that tech into something practical: clearer insights, safer automation, faster optimizations, and decisions that actually reflect your margins and inventory reality.

As platforms begin adopting this new stack, keep an eye on what really changes for you. That’s what we’re doing at Astra too — using these improvements where they genuinely help sellers work smarter, not just to keep up with the buzz.
