Amex Is Drawing the Line for Your AI Shopping Assistant

American Express is setting house rules for the AI Shopping Assistant on your phone. On its third-quarter earnings call Friday, the card giant announced a restructuring that will eliminate about five percent of its global positions, launched its first conversational AI voice agents, and, most notably, drew a line in the sand: outside AI agents will only be allowed to touch customer accounts if they are explicitly approved, according to PYMNTS, which covered the earnings call.

"We need to protect our customer and merchants, and we're only going to allow agents access to our systems that are either approved through API or MCP channels," chairman and CEO Steve Squeri said during Friday's analyst Q&A. In plain terms, your personal AI helper cannot just wander into your Amex account and start booking things. It needs a permission slip first, and the only doors open are official ones.

The guardrails arrive because Amex is simultaneously opening the gates. Restaurant discovery and reservations through Resy launched inside ChatGPT earlier this year, and the company is working with OpenAI on a plugin for discovering and enrolling in Amex Offers. It is also developing purchase-intent authentication, a system that protects eligible purchases when registered agents share intent data and make mistakes. "The transaction of the future will carry more than a payment credential," Squeri said. "It will carry context."

The Customers Spending the Most Are the Youngest

The generational split in the earnings numbers was hard to miss. U.S. consumer spending rose 35 percent among Gen Z cardholders in the quarter, according to the company's presentation. Millennials came next at 11 percent, with Gen X at eight percent and baby boomers at four percent.

Overall consumer purchases in the United States climbed 9.4 percent, with discretionary spending doing much of the heavy lifting. Restaurants led the way, with dining spending up nine percent, the largest travel-and-entertainment category, and Resy restaurants climbing 18 percent. Airline spending also increased, as did purchases of goods and services. Revenue for the quarter climbed to 20.1 billion dollars, and the company reaffirmed its full-year revenue growth outlook of 10 percent.

Why Amex Cares Who Your Agent Is

The Resy example shows what Amex is worried about. Squeri told analysts that agents should not be allowed to repeatedly query Resy for tables in a way that disadvantages other cardholders trying to book dinner. It is a glimpse of the coming etiquette problem: when everyone's assistant can hammer reservation systems at machine speed, the system needs a referee, or the loudest bot wins.

There is also a money question. Analysts asked whether AI tools will help customers maximize rewards and drive up Amex's benefit costs. Squeri said it was too early to determine the expense impact, but added that he expects AI tools to help the company detect gaming and adjust benefits. Translation: if your agent gets too good at squeezing value out of the card, the card will get better at pushing back.

The tension is not lost on anyone watching the AI job cuts 2026 conversation either. Amex took a restructuring charge of 336 million dollars alongside that reduction, and while Squeri described AI's productivity benefits, he did not attribute the full reduction to automation. The company is both deploying AI inside its own walls, where it helps employees resolve service issues and investigate complaints, and policing AI outside them.

What This Means for Your Next Booking

For cardholders, the practical effect is that agentic commerce will come with credentials. Expect "approved agent" labels, registration steps, and disclosures about what your assistant shared to make a purchase. Amex said agentic payment volumes remain small, so most people will not notice a difference yet. But the framework is being poured now: registered agents will get purchase protections, and unregistered ones get the door.

The open question is whether an approved-only model becomes a competitive moat. Amex is rolling out more agents for its business customers, pairing expense management with corporate cards and banking to take on automation-first rivals. If every financial institution builds its own gated garden, your AI Shopping Assistant may need a different badge for every bank, airline, and hotel. Convenience could get complicated before it gets simple.

Shares slipped two percent in early trading Friday, a reminder that investors are watching the balance sheet as closely as the AI demos. The lesson for the generation spending the fastest is simpler: the young professionals reshaping the economy are also the ones who will live with the AI rules being written now.
