ChatGPT Wallet: A Cloud Wallet on Network Rails

Posted on by
Reply

OpenAI launched ChatGPT Walle yesterday and it appears to be a new “wallet model” build on card network agentic VAS (V, MA, AMEX). Agents pay with a network token instead of the card number, and the consumer authorizes each purchase within the OpenAI app. It is live for pro accounts inside dots today (US). Dots is OpenAI’s answer to Muse (Meta’s Muse: The Agent Becomes the Control Point). Launched September 29, Dots are a new class of autonomous agents built into ChatGPT. Unlike a normal ChatGPT conversation, a dot has its own cloud computer, persistent context, and access to the applications you authorize. Wallet is how a dot pays.

This is OpenAI’s second go round in checkout (see Explaining the Death of OpenAI’s Instant Checkout). in round 1, OpenAI tried to take the top of the funnel and the checkout, and merchants said no. ChatGPT Wallet is the opposite bet. The merchant stays merchant of record. The card keeps its rewards and dispute rights. The issuer makes the authorization decision. The token goes into the merchant’s existing checkout form. OpenAI has stopped trying to replace the payments plumbing and is now building on the networks’ plumbing.

European Payments: Android Metaphor

Posted on by

Over the last month, I was fortunate to interview EU banks and non-card payment schemes. The people are just fantastic, and I came away with a new appreciation of the challenges of working in a payments environment with so much “central planning”. The questions I asked myself: How best to achieve the objective of being a “digital first” economy? Centrally planned mandates? or markets with commercial incentives? When there is no margin in payments who can invest in the infrastructure (or governance)?

Europe’s payment ecosystem is shaped by the “central planning” of the ECB and the European Commission: SEPA, PSD2, PSD3 and the Payment Services Regulation (PSR), eIDAS, the Instant Payments Regulation, the digital euro and the EU Digital Identity (EUDI) wallet. I have written about this before, in Payments Innovation in Europe (2011), Building Networks and “Openness” (2011), Open Banking, Open Payments and Trust Networks (2020) and Europe’s Siege (2025). Today’s blog is focused on my new insight: how much of the cost lands on the banks, and how little room that leaves for anything else.

Thought for the day: Mandates build rails. Markets build businesses.

Agentic Problems and Forces Creating Alignment

Posted on by
Reply

In June I wrote Agentic Apocalypse: How to Stop It. That blog was about intent: agents buying the wrong thing, and platforms grading their own homework. Intent is a real problem. It is not the biggest one. The larger problem is the economic model of agentic, which I first framed in Pricing Agentic: Economic Models for a New Kind of Demand and called the Gordian Knot in Agentic Commerce: I’ve Seen a Lot of Revolutions. This One Feels Different.

Today’s blog takes eight questions in turn. The short version: agentic activity is real and growing, agents still get it wrong too often, and nobody has priced the value they create. Merchants pay for everything in commerce, payments and advertising. Any model, agent or platform ignoring this dynamic will fail. Today’s focus is identifying forces that will create alignment (and they favor the card networks).

Shopify Reduces Stripe Dependency

Posted on by

This week Shopify released its Fall ’26 Edition content. The payments news is that Shop Pay now works inside personal agents (Muse, Claude Duet, Grok Bot and Instinct), and it works for brands that are not on Shopify. I found a great tech overview of the payment portion in Shopify Takes Shop Pay Into AI Agents and Off Platform Checkouts (The Defiant, Oct 29, 2026).

I am positive on Shopify as the best agentic enabler for merchants. ShopPay is also the best converting consumer wallet in eCommerce. Edition outlines how ShopPay competes directly with Stripe Link, at the moment Stripe is seeking to expand its consumer role within agent permissioning (see last week’s blog Stripe Link Balance). Stripe and Shopify have been partners for more than a decade. Payments is now a core area of friction.

Walmart Agent Gateway

This month Walmart announced Agent Profiles, the Walmart Agent Gateway and a set of terms for AI agents (Walmart, “Making It Possible for Agents to Shop on Behalf of Customers,” Oct 2026). Walmart is supporting customers the way they want to shop: through the agents they choose, with the customer’s controls and Walmart’s rules. In March I described Amazon vs Walmart: Two Very Different Bets on Agentic Commerce. This is Walmart’s bet made concrete, and IMHO it is the most important retail move in agentic commerce this year.

Walmart just became the retail partner of choice for every third party agent, and it kept the payment, the risk, the customer experience and the support.

Why Banks Are Best Positioned in Intent: Amex Updates ACE to Provide the Model

Posted on by

Wednesday, American Express published its Intent Intelligence framework, a new core service of the Agentic Commerce Experiences (ACE) Developer Kit. I covered the ACE launch in April in American Express Breaks the Agentic Commerce Deadlock: Why Today Matters. In April, Amex said it would stand behind agent errors. This week it published how it will know what the agent was supposed to do.

I have written five posts on the problem of intent in machine to machine (M2M) transactions:

One principle runs through all of them: intent data must flow to the party taking the risk. Amex has now published a framework built around the issuer, the party that authorizes the payment, answers the phone and absorbs the dispute (and COULD take on liability).

Apple – Klarna: Equipment Financing

Last week, Apple launched Apple Upgrade, a device leasing program for iPhone, Apple Watch, Mac, and iPad in the United States, provided by Klarna. Apple simultaneously retired the iPhone Upgrade Program (financed by Citizens Bank) and iPhone Payments.

This is a very big deal, and it is the culmination of a strategy I first outlined over a decade ago. Equipment financing has always been the prize. Everything else Apple has done in consumer finance (Apple Card, Apple Pay Later, Apple Card Monthly Installments, the savings account) was either a stepping stone, a learning exercise, or a partner accommodation. Apple Upgrade is the main event.

Visa Stablecoin Platform

Exec Summary

  • Consumers never wanted stablecoins, they wanted 5% yield or a crypto off ramp, BIS data confirms retail use is under 1% of volume
  • Stablecoins are a settlement innovation, networks did not hijack them, incumbents always adopt new tech to compete
  • Visa’s value is governance, operations, and distribution, VSP is just the next network in the network of networks
  • VSP = single Visa managed environment to mint, burn, move, and manage OUSD, with wallet as a service, passkeys, maker/checker controls
  • OUSD first because compliance and trust win, banks trust banks, not Circle, 63% of corporates want stablecoin access via their bank (EY Parthenon)
  • Use cases anchor on ramps and off ramps, treasury funding, global payouts, merchant settlement, stablecoin linked cards ($7B settlement run rate, 160+ programs)
  • VSP is to stablecoin what Visa DPS is to debit, same playbook, different rails and connection points
  • Visa enables Bank Issuers without picking winners, Mastercard bought BVNK and owns a single roadmap, overlap is real but philosophies differ
  • Enablement models win, every member becomes an investor in the network’s growth

Mastercard Explores Vocalink Sale

Posted on by

The Financial Times reports that Mastercard is exploring a sale of Vocalink, and is also considering a divestiture of the real-time payments unit it built from its 2019 acquisition of the Nets Group’s account-to-account assets. Taken together with April’s $1.8 billion acquisition of stablecoin infrastructure provider BVNK, this is a clean strategic pivot: Mastercard is walking away from a decade-long attempt to build a services layer on top of bank-owned A2A rails, and redirecting that capital toward digital asset infrastructure. It is the right call. It also raises a question Mastercard should be asking itself very carefully before the BVNK integration gets too far along.

Understanding ApplePay in PIN Debit

Payment Geek detail on the EMVCO Dependencies of Debit and How Cap One Solved It

This is a technical addendum to today’s post on the reported JPMorgan/BofA/Wells/PNC exploration of buying Fiserv’s Star network. That post laid out five business and political reasons the deal is unlikely to happen. This one goes underneath the business case to the technical architecture that makes the wallet portion (ie ApplePay, GPay, SamsungPay) of the problem particularly ugly for any bank that thinks owning a PIN debit network gets them out from under Durbin.

The short version: an issuer that buys Star cannot simply route its ApplePay volume through Star. The tokenization and provisioning plumbing that makes Apple Pay work belongs to Visa and Mastercard, sits inside a standards body (EMVCo) that issuers are not members of, and is architecturally structured around the card brand on the card (not the issuer that issued it). A bank that owns Star still can’t put a Star token in Apple Pay; it is a new AID in the phone.
