Paul Graham: Amazon's AI-agent block is 'the first opportunity' for an Amazon competitor
The Y Combinator co-founder said shoppers will want independent agents buying for them — not Amazon's own — as Amazon shares slid and new Similarweb figures put Muse's daily active users at 2.18 million.

Paul Graham says Amazon’s decision to block AI shopping agents from its platform may be the most consequential competitive opening in the company’s history. “Amazon banning agents is the first opportunity I’ve seen since Amazon was founded for a start-up to create an Amazon competitor,” the Y Combinator co-founder wrote on X late Wednesday, in comments reported by Barron’s on Thursday.
Graham argued that shopping agents will become a primary use case for personal AI assistants — and that shoppers will prefer independent agents to Amazon’s own. “People will want agents to buy stuff for them. It will be one of the main use cases. And they won’t want to use some Amazon-supplied agent to do it,” he wrote.
Barron’s reported that Amazon shares fell 1.9% to $255.05 on Thursday afternoon. Amazon did not immediately respond to Barron’s request for comment; the company has previously said third-party applications that make purchases on behalf of customers should operate openly and respect retailer decisions about participation.
The comments follow Amazon’s block of Meta’s Muse, which prevented the assistant from completing checkouts on Amazon.com after Meta declined to remove Amazon from Muse’s shopping experience, a standoff All Things Muse covered earlier this week. Amazon has resisted outside shopping agents more broadly, Barron’s noted, blocking tools from OpenAI, Google, and Perplexity while promoting its own Alexa shopping agent, which can also execute transactions on non-Amazon sites.
Barron’s, citing analytics firm Similarweb, reported that Muse’s daily active users reached 2.18 million at the start of the week. Sensor Tower estimates reported earlier put total Muse installs above 6.6 million.
A Demand Signal, Not Just a Policy Fight
Graham later extended the argument beyond Amazon, writing that any business banning agents creates an opening for a startup competitor: if companies feel the need to ban agents, it must mean people want to use them, and that demand implies a market for agent-friendly alternatives.
The framing matches how retailers are already choosing sides. Shopify, which has partnered with Meta on agentic checkout, lets Muse complete purchases through Shop Pay (https://www.allthingsmuse.com/articles/shopify-muse-shop-pay-checkout/), and retailers including Walmart, Gap, Sephora, and Wayfair have signed on as Muse shopping partners. Barron’s noted that smaller companies like Shopify see the moment as a chance to gain e-commerce share, partly because they depend less than Amazon on funneling eyeballs toward sponsored products and advertising.
ING senior economist Katinka Jongkind made a similar point in a research note Wednesday, arguing that autonomous shopping agents shift purchasing from an active task to an increasingly automated background process.
Until Amazon reverses its block or a startup takes up Graham’s bet, the split is clear: Amazon promotes its own Alexa shopping agent while Shopify and its partner retailers let Muse handle the checkout.
