Amazon Launches Seller Assistant Powered by Claude
Amazon has upgraded its Seller Assistant for third-party sellers by adding agent capabilities that can monitor inventory, advertising, product pages, and compliance data around the clock. It can automatically adjust prices, seek competitive opportunities, or issue alerts based on rules preset by sellers. This system runs on Amazon Bedrock and utilizes Anthropic's Claude model.
Execution permissions are divided into two tiers: sellers can either receive suggestions only or authorize the system to execute actions directly. Each operation leaves a complete audit trail and is constrained by rules set by the seller. The system includes built-in templates covering high-frequency scenarios such as account health monitoring, order summaries, and pricing analysis. The workflow can continuously monitor condition changes and respond automatically outside of the Seller Central platform.
The new version introduces persistent memory: the system will remember sellers' pricing habits, inventory cycles, and growth targets, synchronizing this information between the seller platform, Amazon Quick, and Claude. The new visual workspace supports scenario simulations and comparisons of different pricing strategies. Amazon has also launched a Seller Assistant plugin, which is fully available on Amazon Quick and in testing on Claude, initially open to U.S. sites with plans to expand to other countries and integrate more platforms in the future. Seller data is retained within Amazon's infrastructure and is not shared externally.
In terms of coverage, related features have been made available to over 90% of partner sellers globally, supporting sellers' native languages, with active users reaching hundreds of thousands and a suggestion adoption rate exceeding 90%. The Seller Assistant was first launched in 2023 as a generative AI tool, with agent capabilities added in September 2025, marking its third major upgrade. James Oliver, founder of the energy bar brand Atlas Bar, stated that what used to take hours to manually input Amazon data into AI tools is now fully integrated, "What used to take an afternoon is now completed instantly."
The accompanying promotional strategy is to offer the tools for free: by December 31, 2026, primary account holders can use Amazon Quick Plus for free for 12 months, with two additional collaborators per account also receiving one year of free access. In the same release batch, Amazon announced logistics measures: the number of pickup points in the U.S. has increased to nearly 30,000, with an estimated 100 million packages expected to be picked up from these points this year; the newly launched Standard Ocean Express shipping service will transport goods via direct rail from the Port of Los Angeles to East Coast warehouses to shorten transport times and reduce stockout risks.
In terms of market mechanisms, this is a platform-led tool descent without financial transactions, but it will change the flow of sellers' budgets. The most direct beneficiary is Amazon: as seller operational efficiency improves, the use of advertising and logistics services will be more robust, making it harder for sellers on the platform to leave. Anthropic's Claude has gained significant commercial usage through Bedrock. Third-party seller SaaS tool providers, such as Helium 10, Jungle Scout, and Pacvue, which offer automatic pricing, product selection, and advertising management tools, are under pressure: as the platform incorporates these functions for free, their subscription revenues and data interface values will be compressed.

Amazon's relationship with third-party sellers has always been its biggest regulatory risk. In 2020, the European Commission accused Amazon of using non-public data from third-party sellers to support its own products, and in December 2022, Amazon settled with the EU by promising to rectify the situation. In September 2023, the U.S. FTC, along with 17 states, sued Amazon for monopoly practices, accusing it of punishing sellers who sell at lower prices on other platforms and effectively forcing sellers to use its logistics services, claiming that Amazon had used an algorithm codenamed "Project Nessie" to test price increases. Currently, third-party sellers contribute over 60% of sales units in the Amazon marketplace, and seller services revenue is one of its largest businesses; any intervention by the platform in seller decisions will be subject to antitrust scrutiny.
In terms of resource mobilization, this upgrade transforms Amazon's investment in Anthropic into competitive strength for its own business. Amazon invested a total of $8 billion in two tranches in 2023 and 2024 in Anthropic, becoming its main cloud service and training partner, and is building a large-scale computing cluster "Project Rainier" based on its self-developed Trainium chips for Anthropic. The Seller Assistant runs on Bedrock, essentially creating a closed loop using its own cloud, its own invested model, and its own seller data: investment drives cloud revenue, cloud drives model usage, model improves seller efficiency, and seller efficiency further drives advertising and logistics revenue.
The closest historical reference is Google's Performance Max. In 2021, Google launched this fully automated advertising product, where advertisers only need to set budgets and goals, while bidding, placements, and creative combinations are left to the algorithm. The result was improved efficiency for advertisers, but the control over bidding and placement decisions shifted to Google, making it increasingly difficult for advertisers to see where their money was actually spent. A corresponding case in e-commerce is Shopify's launch of the AI assistant Sidekick in 2023, providing merchants with natural language operational suggestions. The difference with Amazon is that it directly takes on the execution authority. The platform's agents are currently in an expansion phase from "suggestions" to "execution," with over 90% adoption rate indicating that sellers are beginning to get used to delegating decisions.
Structurally, this represents a transfer of pricing power. When hundreds of thousands of sellers delegate pricing, advertising bids, and inventory decisions to the same platform agent, while the platform simultaneously holds all competitive product prices, traffic distribution, and demand data, prices nominally remain set by individual sellers, but are actually coordinated by the same algorithmic logic. This is highly similar to the logic behind the U.S. Department of Justice's lawsuit against real estate pricing software RealPage starting in 2024: there is no collusion agreement, but the shared algorithm will lead to price convergence. Once the platform's algorithm becomes the default decision-maker for the majority of sellers, antitrust scrutiny will extend from "Does the platform favor its own products?" to "Does the platform's algorithm set prices for the entire market?"

Whoever makes decisions for you is pricing the entire market.
The price of free tools is that you give up decision-making power.
The platform first gives you suggestions, then executes for you, and finally defines what is considered correct.
