eBay Bars Unauthorized AI Buying Agents Over Bid-Sniping Risks as Agentic Tools Drive 20% of Holiday Sales
2 articles · Updated · aijourn.com · May 23
Summary
Late January changes to eBay’s user agreement explicitly banned unauthorized third-party “buy for me” agents and AI chatbots from placing orders, while still allowing approved agents on the platform.
eBay tied the move to AI-driven bid sniping in auctions, where bots place maximum bids in the final seconds, limiting human response time and potentially hurting both seller outcomes and eBay revenue.
The restriction comes as agentic commerce accelerates: AI search and agents influenced or drove 20% of 2025 holiday e-commerce sales, shifting shopping from assisted discovery toward autonomous purchasing.
Fraud pressure is also rising. E-commerce marketplaces logged a 19.2% net fraud rate in 2025 verification attempts, with generative AI and agent-specific threats such as hijacking, memory poisoning and counterfeit assistants widening the attack surface.
The broader industry challenge is building controls for agent-led shopping, including biometrics, liveness checks and possible human-only zones, before zero-click commerce can scale safely.
AI agents drove 20% of holiday sales but also a 500% fraud spike. Can e-commerce survive its 'zero-click' revolution?
With eBay creating 'human-only' zones to fight bots, is this the beginning of a new segregation on the internet?
Hackers are 'poisoning' AI shopping agents to steal your data. How can you trust a bot that has its own memory?

eBay has updated its User Agreement, effective February 20, 2026, to specifically ban unauthorized AI-powered agents and bots on its platform. This move is a strategic response to the rapid rise of agentic commerce tools already used by consumers and businesses. By clarifying its anti-scraping rules, eBay aims to maintain platform integrity and ensure a controlled environment for innovation. The new policy reflects eBay’s effort to adapt to evolving technologies, protect its business model, and manage how AI-driven automation interacts with its marketplace, balancing innovation with security and operational control.
