Amex Launches ACE; Assumes Agentic AI Risk
The newsletter reports American Express has introduced Amex Agentic Commerce Experiences (ACE), a program under which Amex will assume financial responsibility when AI agents make mistakes. The piece frames this as a notable step in agentic AI for commerce and contrasts Amex’s move with Visa and Mastercard work on agent authentication. It also highlights Anthropic’s growing role in financial infrastructure — noting UK financial institutions gaining access to Anthropic’s Claude Mythos model — and references related developments such as Shopify building AI agents, agents opening bank accounts, and guides for building agentic systems.
Investors Are Betting on AI Agents That Shop for You
Venture capitalists are increasingly funding startups building AI agents that can shop on behalf of consumers and handle payments. The article maps the emerging market for "agentic commerce," covering personal assistants like Instinct and Town, shopping search tools like Daydream, payment infrastructure startups like Catena Labs and Basis Theory, and marketing tech such as Profound. Major platforms are also moving: OpenAI and Stripe launched the Agentic Commerce Protocol, Google operates the Agent Payments Protocol, and Visa and Mastercard introduced Trusted Agent Protocol and Agent Pay. However, the space faces trust and fraud challenges, illustrated by Phia's cookie-stuffing scandal and an Instinct agent error that cost a user around $300. Investor interest remains strong, with millions raised across the sector, even as enterprise adoption lags due to compliance and security concerns.
Agentic Commerce: Buyers Gain Buying Power
A Substack executive briefing analyzes Stripe’s announcements at Sessions 2026, arguing the company unveiled infrastructure to enable “agentic commerce” — where AI agents (in ChatGPT, Gemini, coding agents, procurement workflows, etc.) initiate and complete purchases on behalf of buyers. The piece claims this shifts control from seller-owned funnels to buyer-side contexts, with Stripe’s Link wallet for agents moving payment authority to the buyer’s agent. It highlights fraud and token-theft as the primary constraints for distributed agent payments and notes major firms (Microsoft, Meta, Visa, Mastercard, PayPal) are pursuing similar architectures. The article discusses implications for branding, reachability, and how businesses must become “callable” by agents rather than expect buyers to enter seller-controlled stores.
