Klarna and Stripe bring BNPL to agentic commerce

Klarna and Stripe are expanding their partnership to ensure buy now, pay later (BNPL) options remain available in the emerging ecosystem of AI-driven commerce.

Klarna and Stripe bring BNPL to agentic commerce

The collaboration will allow Klarna’s flexible payment products to be used within AI agent–initiated purchases via Stripe’s Shared Payment Tokens infrastructure.

The development reflects a broader shift in digital commerce, where autonomous AI systems are increasingly able to search for products, compare prices and execute transactions on behalf of consumers.

As this model evolves, the design of payment rails will play a critical role in determining which payment methods remain available at checkout.

Shared Payment Tokens and Architecture

At the centre of the integration is Stripe’s Shared Payment Tokens (SPTs), a payment mechanism designed specifically for agentic commerce environments.

The system enables AI agents to initiate transactions using a customer’s preferred payment method without accessing sensitive card or account details.

Instead, the AI agent operates within a permissioned framework in which payment credentials are tokenised and securely referenced through Stripe’s infrastructure.

This approach allows automated purchasing while maintaining privacy and compliance standards.

With Klarna joining the SPT framework, BNPL options will be able to flow through the same secure layer as traditional card payments.

For merchants already offering Klarna through Stripe, the functionality will require no additional technical integration — a decision likely intended to accelerate adoption.

Addressing a Structural Gap in AI Checkout

Until now, most agentic commerce models have relied primarily on card-on-file payments.

While efficient, this default architecture effectively excluded alternative payment methods such as BNPL, potentially limiting consumer choice and reducing merchant conversion opportunities.

By integrating Klarna into Stripe’s tokenised payment layer, the companies are attempting to address that structural gap.

AI agents acting on behalf of consumers will be able to present flexible payment options during the automated checkout process, rather than defaulting to a single funding source.

For merchants, the implications are significant. BNPL has consistently demonstrated higher basket sizes and improved conversion rates in traditional ecommerce environments.

Extending those benefits into AI-driven purchasing flows could prove commercially attractive as agentic shopping gains traction.

Embedding Payment Choice in AI-Led Commerce

The partnership also illustrates a deeper strategic concern within the payments industry: ensuring that new commerce architectures do not inadvertently concentrate power around a narrow set of payment instruments.

As AI systems increasingly mediate consumer purchases, the underlying infrastructure will shape the economic dynamics of online retail.

Payment providers that fail to integrate into these automated frameworks risk becoming invisible to both merchants and consumers.

Klarna’s decision to align with Stripe’s agentic payment tokens therefore represents an early effort to secure relevance within a rapidly evolving checkout environment.

While the initial rollout will focus on US merchants already using Klarna through Stripe, the companies suggest that further integrations and expansions are likely.

As agentic commerce moves from experimental pilots to real-world deployments, ensuring that flexible payment options remain embedded in the transaction flow may prove critical to preserving competition — and consumer choice — in the next generation of digital commerce.
