3 Payment Stocks Poised For AI Agent Shopping Growth

AI agents like Meta’s new Muse are starting to shop, book, and pay on behalf of users, which could quietly reshape who actually controls online transactions. That shift creates both risk and potential upside for businesses wired into the pipes of digital payments. This article unpacks what that means for investors and walks through three stocks exposed to this AI commerce story that may merit a closer look.

The stocks profiled below are just a starter pack from this AI commerce idea. The full screen surfaced 72 more publicly listed payment infrastructure companies with equally compelling stories that are not covered in this article. To identify your own highest conviction angles on this theme, head straight into the AI-Commerce Transaction Infrastructure Providers screener to filter and analyze the full set of candidates.

Paymentus Holdings (PAY)

Paymentus Holdings sits right on the AI-commerce rails, running cloud software that lets utilities, insurers, banks and other billers accept and route digital payments that AI agents could increasingly trigger in the background.

Paymentus Holdings provides cloud-based bill payment software that lets billers present invoices and accept card, echeck and digital wallet payments, generating about $1.4b from services to financial companies, and has a market value of roughly $3.8b.

Increasing adoption of digital and electronic bill payment solutions by both consumers and businesses, driven by the ongoing shift away from cash/checks, underpins higher transaction volumes and supports sustained transaction-linked revenue expansion.

What happens to Paymentus Holdings’ margins if one unseen pressure on how much large clients are willing to pay quietly shifts?

If that pricing power question is on your mind, read the full narrative for Paymentus Holdings to see how AI driven billing volumes could reshape Paymentus Holdings’ risk and reward profile.

Flywire (FLYW)

Flywire plugs directly into the AI-commerce theme by wiring complex education, healthcare, travel and B2B payments into software workflows, so any shift toward automated agents booking and paying in the background flows through the rails this US$2.1b platform already runs.

Flywire Corporation operates a payment enablement and software platform, generating about US$714 million from data processing services, with tools for invoicing, reconciliation and embedded payment workflows across education, healthcare, travel and B2B clients, and carries a market value near US$2.1b.

Flywire's accelerating use of AI and machine learning, which is already delivering tripled payment volume capacity and 25% process efficiency gains, could usher in industry-leading net margin expansion, positioning Flywire as a top-tier fintech for EBITDA growth and margin resilience.

The real swing factor is what happens to that AI-fuelled operating leverage if a single assumption about client adoption or mix quietly shifts.

If that assumption worries you, the full narrative for Flywire shows how Flywire’s AI capacity gains, client mix shifts and fee economics could still combine into a stronger long term story.

Adyen (ENXTAM:ADYEN)

Adyen is one of the purest plays on the AI-commerce wiring, with a single platform that handles checkout, risk and settlement for merchants while generating about €2.6b from Payment Services and carrying a market value near €27.6b.

For AI agents that handle shopping and checkout in the background, what matters is who controls the payment pipes and data, and Adyen is building its pitch exactly around that role.

The market is right to be skeptical, but it may be too quick to dismiss that expansion as mere story stock language. Management has been very explicit that more value is being created before the payment moment and after it: in identity, decisioning, promotions, billing, and money movement.

What happens to Adyen’s already high profitability if one unseen pressure on how much merchants value that broader stack quietly shifts?

If that shift in merchant appetite is what you keep circling back to, the full narrative for Adyen describes how Adyen’s broader stack could still accelerate value creation.
