Elon Musk has a new target in his sights, or at least in his replies. This week the X owner posted a short, pointed message: "Maybe we should start a competitor to Amazon," followed by a thinking-face emoji.
He was quote-posting an X user, @thecsguy, who complained that Amazon is blocking Grok bots from ordering on its site and that Musk's answer amounted to having your bot buy somewhere else.
The post spread fast. Within about three hours it had roughly 2.5 million views, 76,000 likes, 8,600 reposts and 10,000 replies.

Why is Amazon blocking AI shopping agents?
Musk's post lands in the middle of a growing standoff between Amazon and AI shopping agents, the software assistants that can browse, compare and buy products on a person's behalf.
According to an analysis by Cybernews, Amazon's robots.txt file now shuts out the crawlers and agents behind Claude, ChatGPT, Copilot, Perplexity, Manus, Grok and Google. In September, Amazon cut off Meta's new Muse agent, citing its Conditions of Use. Amazon said the agent did not identify itself and appeared to store customers' credentials. GeekWire has also reported that Amazon moved against shopping agents from Google and OpenAI.
The company's position is that unauthorized agents put customer accounts and data at risk. At the same time, Amazon is building its own shopping agent, Buy for Me.
It has also gone to court. Amazon sued Perplexity in November 2025 to keep the shopping feature in Perplexity's Comet browser off its site. In August, the Ninth Circuit Court of Appeals reversed the injunction Amazon had won against Perplexity's agent.

Paul Graham's case for an Amazon rival
The tweet builds on an argument from Y Combinator co-founder Paul Graham. Graham said Amazon's ban on AI agents is the best opening for a startup to challenge Amazon since the company was founded. His logic: shoppers will increasingly hand purchases to AI agents, and they won't want Amazon deciding which agents they can use. A company only bans something people actually want, he argued.
Musk quote-posted that argument on October 8 with a one-word reply: "Seriously." That reaction was not an announcement of a business, and neither is this week's tweet. Neither Musk nor xAI has announced any retail project.
Why Amazon cares so much
There's real money in keeping humans browsing. Amazon generated about $69 billion in advertising revenue in 2025, up 22%, according to an analysis by TIKR. Ads only work if people see them. If AI agents take over product search and price comparison, Amazon loses some of its power to steer shoppers toward its own recommendations and sponsored listings.
Could Elon Musk actually build an Amazon competitor?
On paper, Musk has some of the pieces: Grok as the shopping assistant, X as a massive distribution channel, and a long record of entering industries others considered locked up.
But the skeptics have a strong case. No startup today comes close to Amazon's catalog, warehouses or delivery network, and that took Amazon decades to build. An agent hunting for the best price and fastest delivery may end up choosing Amazon anyway. And Amazon could simply open its doors to approved agents, or buy any competitor that gains traction by welcoming them.
For now, it's one emoji-capped tweet. But it puts one of the world's loudest voices behind a question the retail industry can no longer avoid: what happens to Amazon when software, not people, does the shopping?
Quick answers

Why did Amazon block Grok?
Amazon's robots.txt blocks the agents and crawlers behind several AI assistants, including Grok, according to Cybernews. Amazon says unauthorized agents put customer accounts and data at risk.
What did Paul Graham say about Amazon?
Graham argued that Amazon's ban on AI agents is the biggest opening for a startup to challenge Amazon since its founding, because shoppers will want to choose their own agents.
