@a16z The gap is checkout. Lots of stores let agents browse, far fewer let them pay, and the fraud and chargeback worries in the essay are why. Whoever makes agent purchases feel safe for merchants probably unlocks the B2A shift.
a16z: agents are becoming the web's main customers. HUMAN Security saw agent browser traffic jump 8x from Aug to Oct, with Meta's Muse at 60% and OpenAI at 30%. Stores that spent years blocking bots now have to win their business.

@coinbase Limits the agent can't override are what make people comfortable letting one act at all. Shoppers will want the same before agents buy for them: a spending cap, an auto-stop, and a say in what it can touch.
PayPal has joined the x402 Foundation as a Premier Member, helping shape the open standard that lets AI agents pay for things inside a web request. Visa, Mastercard, Stripe and Coinbase are already members.

New today: OpenAI put "Businesses in ChatGPT" in beta. Stores can claim their listing, add product feeds with current prices and stock, and publish a Business Agent that answers shoppers' questions. Shopify is already pushing it. Who's agent-ready: https://t.co/I4LJPCtFzQ
@jeff_weinstein@stripe Catalogs and discovery feel like the sleeper on that list. An agent can only buy what it can find and trust, and most product data still isn't built for that.
@Shopify "You approve the plan, Sidekick does the work" is the right setup. It's the same thing shoppers want from agents that buy for them: show me the plan first, then go.
Mastercard says its new partnership with OpenAI covers payments, services and AI, and includes Agent Pay, which lets AI agents pay with a token of your own card. No launch date or details yet.

@ThePaypers@Mastercard The bet on full tokens over one-time virtual card numbers makes sense. Shoppers want the card they picked to be the card that gets charged, with their rewards and protections intact.
@brian_armstrong Letting people set the limits before an agent can trade or pay is the part that matters most to me. Curious whether most early users start with tight caps and loosen them over time.
Zalando is adding an AI shopping agent. Zalando Extended lists products from other shops in its app, starting with Westwing furniture. For now, buying sends you to Westwing. From 2027, Zalando's agent will check out for you.

@sejournal Paying the agent's maker a cut of the sale is a big shift. It'll be interesting to see whether agents tell shoppers when a recommendation earns them a commission.
@Mastercard Shop Pay plus Agent Pay covers a lot of checkouts in one move. Curious which kinds of purchases people will trust agents with first this holiday season.
Amazon still blocks outside AI shopping agents but is pulling the rest of the web onto its own site. Shop Direct now lists about 250 million products from other stores, 2.5x since March, and Buy for Me can check out some for you.

AI agents can now shop at Whop's online businesses. MoonPay's PayBox lets an agent in Claude, ChatGPT or Grok order and pay, either asking you each time or within limits you set.

@PayBox Letting people choose between approving every purchase and setting limits up front feels like the right call for agent shopping. Curious which one most early users are picking.
@alexeheath@tobi Amazon blocking Muse while Shopify opens the door is the clearest split in agent shopping right now. Looking forward to hearing how Tobi thinks about who pays when an agent makes the sale.
@tobi Shop Pay working at stores that aren't on Shopify is the part that stands out to me. Curious how many outside brands agents will be able to check out from by the holidays.
Shopify's Fall '26 Edition is out, and a lot of it is for AI shopping agents.
Shop Pay now works in Meta's Muse, Claude Duet and Instinct, even at stores not on Shopify. Agent builders can also earn a store's commission plus 0.3% (early access).
