For most of your adult life, you have decided which card comes out of your wallet. Maybe it is the one with the best cashback. Maybe it is the one on top.
That decision is starting to move to software.
More than one in 10 online shoppers will routinely use AI agents to shop and pay by 2030, according to a report published Sept. 8, 2026 by Mastercard (MA). That works out to more than 300 million people worldwide.
The number reads like a distant projection. Recent US data suggests the behavior is already further along than that.
What the Mastercard report predicts
The report, titled “A short history of the future of shopping and payments,” pairs original consumer research with predictions from four futurists in the US, Europe and Asia, according to Mastercard.
Groceries, medicines and subscriptions are expected to be among the first purchases people hand over.

One caveat matters for a US reader. The underlying survey covered 26,000 parents and teenagers across 13 European markets, run with Opinium in June and July 2026. The 300 million figure is a global extrapolation, not a US measurement.
Mastercard has flagged the trust question itself. Its chief executive raised consumer protection concerns about agentic commerce earlier this year.
Why the 2030 timeline may already be behind
Agentic shoppers could reach 190 billion to 385 billion dollars in US e-commerce spending by 2030, capturing 10% to 20% of the market, according to Morgan Stanley Research.
The more striking number sits further down that research. Roughly 23% of Americans bought something using AI in the past month, Morgan Stanley estimates, with groceries and consumer packaged goods leading the way.
More Artificial Intelligence:
- Anthropic researcher resigns and his reason is a warning to us all
- US spies say someone is secretly copying America’s AI
- AI data center backlash accelerates ahead of elections
Those two numbers describe different behaviors. Buying with AI help is not the same as handing an agent your card and letting it decide. The distance between them is exactly what the next four years will close.
Morgan Stanley is measured about how fast that happens. “To reach widespread adoption, companies first need to develop products and consumer habits have to evolve,” said Brian Nowak, head of US Internet Research at the bank.
Why one payments executive says 2028
Vadim Drozd, CEO of payment orchestration platform FinteqHub, thinks the 2030 date understates how quickly this lands.
“Mastercard’s forecast appears overly cautious and conservative. Mass adoption will likely begin earlier because users won’t need to learn a separate payment tool,” Drozd said.
His argument rests on distribution. Agents are being embedded in smartphones, banking apps, marketplaces and browsers, so the first uses will be things you already do without thinking.
Booking travel. Renewing a subscription. Finding the better price.
I have watched this pattern through several product launches this year, and adoption tends to arrive through defaults rather than downloads. Nobody chose to start using tap-to-pay. It simply appeared in the phone people already owned.
Drozd puts the real turn closer to 2028, even if fully autonomous purchases stay niche past that.
What this does to your rewards card
Here is the part that touches your money directly.
Today your bank competes for one decision, which is whether its card becomes your default. An agent does not have a default. It can spend as long as it needs comparing cashback rates, fees and exchange rates before every single purchase.
“The more decisions AI makes, the less brand inertia and visual appeal of checkout will matter, and the more important price, speed, fees, and the likelihood of a successful transaction will be,” Drozd said.
That points pressure at legacy loyalty programs. A rewards structure built to win your habit has less to do when the buyer is software running a comparison every time.
Drozd sees the same force cutting the other way for consumers, with agents flagging promotions and cashback categories that match how you actually spend.
I would flag one thing about his read. FinteqHub sells intelligent transaction routing, which is precisely the technology his argument says becomes more valuable, so weigh the timeline against the interest.
Where Visa’s CEO puts the line today
Not everyone in payments sees the handoff arriving that fast.
Consumers are adopting AI for shopping but have not yet moved to autonomous payments, Visa (V) CEO Ryan McInerney said Sept. 8, 2026 at the Goldman Sachs Communacopia and Technology Conference, according to PYMNTS. People compare products in a chatbot, then finish the purchase on the seller’s own site.
McInerney has been vocal on the topic, laying out a broad case for AI and agentic commerce on an earnings call in April 2026.
Two payment networks, same week, different reads on how close the last step really is.
Steps to take before an agent touches your card
You do not need to do anything today. A few things are worth knowing before you do.
- Check your issuer’s agent controls. Ask what caps and merchant limits apply to agent-initiated transactions, since those are the main protection on offer right now.
- Audit your default card. Whichever card sits first in your digital wallets and shopping apps is the one an early agent will reach for.
- Confirm your chargeback rights. Card networks have said liability follows standard tokenized transaction rules, though verify that with your own issuer rather than assuming.
The cards that win the next few years will be the ones that price well on a spreadsheet. Your job is to make sure the software doing the comparing is working for you.
