Imagine you ask an AI assistant to order you a new laptop. It finds the perfect model, adds it to your cart, and then, just before checking out, asks: "Would you like to pay for this over time?" That's the future Affirm Holdings Inc. (AFRM) and Stripe are building together.

The buy-now-pay-later leader announced Tuesday it's deepening its partnership with the payments giant Stripe. The goal? To bake Affirm's transparent installment plans directly into the checkout flows powered by AI shopping agents.

Here's how it's supposed to work. Stripe has a technology called Shared Payment Tokens. Think of it as a secure, one-time-use digital key that represents your payment method. An AI agent can use this token to initiate a purchase on your behalf without ever seeing your actual credit card number or bank details.

The new integration means that when an AI agent gets to the virtual checkout counter, it can present Affirm as a payment option. If you choose it, you'd still go through Affirm's instant approval process, pick your repayment schedule (like paying in four interest-free installments), and complete the purchase—all without leaving the chat or interface you're using. Stripe handles the complicated payment plumbing in the background, keeping everything secure.

"With our Shared Payment Tokens expanding to include Affirm, AI agents will be able to present buy now, pay later options at checkout," said Kevin Miller, head of payments at Stripe. "Integrating Affirm into agentic payments helps businesses drive conversion while giving shoppers more choice in how they pay."

In plain English, they're trying to make automated shopping feel less robotic and more flexible. The bet is that if you're already comfortable letting an AI buy stuff for you, you might also appreciate the option to spread out the cost.

This isn't a brand-new friendship. Affirm and Stripe have been partners since 2021, working together on online checkouts and even in-person payments via Stripe's Terminal hardware. This shared-token move is essentially about extending that existing installment-payment capability into the emerging world of AI-led commerce.

Affirm also took a moment to remind everyone how its model works: it's financing tied to a specific purchase, not a revolving line of credit like a credit card. You get approved for that one laptop, not for a $2,000 spending limit you can use anywhere.

And Stripe isn't the only dance partner. Affirm says it's working with other platforms and merchants to plug its installment payments into agent-driven commerce, name-checking support for Google's Agent-to-Agent Protocol and Universal Commerce Protocol initiatives. They're clearly trying to be the pay-over-time option of choice wherever AI is doing the shopping.

The announcement comes on the heels of some very healthy numbers from Affirm. The company's second-quarter earnings came in at 37 cents per share, beating the analyst consensus estimate of 30 cents. Revenue hit $1.12 billion, also topping the Street's forecast of $1.06 billion.

Other metrics were strong too: Gross merchandise volume (the total value of everything purchased through Affirm) jumped 36% year-over-year to $13.8 billion. The company's active customer base grew 23% to 25.8 million, and the number of merchants using Affirm soared 42% to 478,000.

Looking ahead, Affirm expects third-quarter revenue between $970 million and $1 billion, roughly in line with estimates. More notably, the company raised its full fiscal year 2026 revenue outlook to a range of $4.09 billion to $4.15 billion.

Investors seemed cautiously optimistic about the Stripe news. Affirm's stock was up about 1% in premarket trading Wednesday.
