Big websites are starting to block AI shopping and browsing agents

A growing number of popular websites are refusing to work with AI agents that browse and act for users, The Verge reported on October 17, 2026. Users of agents from Meta, xAI, OpenAI and Instinct have reported being blocked on major sites in recent weeks.

Some blocks are official. Yelp told TechCrunch it only lets in agents whose makers pay to license its data. Delta Air Lines is stopping agents from booking tickets. JPMorgan Chase and Charles Schwab confirmed they block agents from customer accounts, citing security. Users also say sites such as Cars.com and Amtrak stopped working, which hints that other companies are blocking quietly. Amazon has told Meta that its Muse agent's access breaks site rules, continuing a fight that began when it sued Perplexity over agent shopping.

Not every failure is deliberate. Anti-bot and anti-fraud systems often trip on agents because they look like automated scripts. Meta argues that blocking an agent is the same as blocking the shopper using it, and it has signed shopping deals with retailers such as Walmart, Best Buy and Sephora instead. Shopify has also opened its stores to agents. One AI safety executive told The Verge the blocks reduce how useful agents can really be.

Why it matters

Agent builders need to plan for blocks, bot checks and paid access deals, and site owners need a clear policy on which agents they allow.
