OpenAI’s Instant Checkout heralds the rise of autonomous AI-driven shopping

OpenAI’s new Instant Checkout feature inside ChatGPT signals a revolutionary shift towards fully autonomous AI shopping, enabling seamless transactions within conversational interfaces and transforming the future of e-commerce.

Artificial intelligence is poised to revolutionise shopping in ways previously confined to science fiction, moving far beyond search and recommendation engines to become autonomous buyers on our behalf. In late 2025, OpenAI quietly launched...

“Instant Checkout” inside ChatGPT, enabling users to complete purchases directly through conversational interactions — no extra clicks or website navigation required. This feature, co-developed with the payment giant Stripe and supported initially by Etsy and Shopify merchants, signals the emergence of what industry experts call “agent commerce,” a major structural shift in e-commerce.

Instant Checkout transforms ChatGPT from a mere advisor into a full-fledged storefront. Instead of sending users to external retailer websites, ChatGPT now handles the entire transaction within the chat interface itself — collecting shipping details, authorising payments securely via Stripe’s tokenisation system, and confirming orders in real time. The system uses the new Agent Commerce Protocol (ACP), an open REST API designed to standardise communication between AI agents and merchants. ACP creates a universal language for commerce that allows any compliant AI to transact seamlessly with any compliant merchant, echoing how HTTP standardised the web decades ago.

During its beta phase, Instant Checkout supports single-item purchases from select U.S. Etsy sellers, with plans to expand to multi-item carts and Shopify’s extensive network of over a million merchants. Merchants pay a small fee per transaction, while consumers benefit from transparent pricing with no added charges. Beyond convenience, this open standard approach encourages interoperability and trust across platforms and providers.

OpenAI’s collaboration with major retailers is expanding rapidly. For instance, the retail giant Walmart is preparing to integrate Instant Checkout into ChatGPT, aiming to transform shopping from traditional online browsing to dialogue-driven transactions. This move allows shoppers to specify needs conversationally — like groceries or household items — and receive tailored recommendations and direct purchasing options, bypassing website navigation altogether. Walmart’s partnership marks one of the largest integrations of agent commerce with a major retailer, utilising familiar payment options such as Apple Pay, Google Pay, and Stripe.

This evolution points to a distinct shift from “assisted shopping,” where AI offers suggestions and streamlined checkouts still require human finalisation, to “delegated consumption.” According to Bain & Company, this means consumers will increasingly allow AI agents to act autonomously within defined limits, completing tasks end-to-end — for example, booking flights or reordering household essentials. Their 2025 U.S. consumer survey reveals a gap between current usage of autonomous AI shopping (just 10%) and consumer openness—64% are willing to try AI-assisted shopping, albeit only 24% are comfortable letting AI handle payments unsupervised. This underscores trust and usability as the key barriers to widespread adoption rather than lack of interest.

Trust is indeed the currency of agent commerce. Security, transparency, and user control remain paramount concerns. Data from Bain and Salesforce confirm that while AI advancements intrigue consumers, 63% see trust as more crucial than ever, and 51% worry about data mishandling by companies. Furthermore, 68% want to be explicitly informed when interacting with AI agents. Demographically, younger generations, especially Gen Z in the U.S. and millennials in India, tend to be more receptive to AI agents shopping for them.

To address these issues, Instant Checkout incorporates explicit confirmation steps to prevent unintended purchases and supports features such as spending limits, multi-factor authentication, and easy refund processes to mitigate risks. These safeguards are crucial since errors like ambiguous prompts, outdated merchant data, or subscription traps could lead to consumer dissatisfaction and loss of trust. Regulatory bodies are expected to impose mandatory standards on such AI commerce systems as the technology scales.

There are also significant economic implications. OpenAI leverages ChatGPT’s massive user base—estimated at 700 million weekly users—to introduce a new revenue stream via transaction fees. Merchants gain access to this audience without the need to develop their own conversational systems, evident in the positive market responses with Etsy’s and Shopify’s shares rising by 7.3% and 4.5% respectively following the Instant Checkout announcement. For Stripe, co-creating ACP cements its role as the principal payment facilitator in the AI commerce ecosystem, potentially giving it an early competitive advantage.

Design principles emerging from combined insights of Bain, Salesforce, and behavioural science emphasise radical transparency, privacy, human-in-the-loop confirmation, convenience, strong brand partnerships, and robust error handling as the foundation for trustworthy AI commerce. Behavioral research also highlights that trust develops when AI demonstrates competence, integrity, and empathy, although initial algorithm aversion makes user control and order review critical during early adoption stages.

Cultural and regional differences further complicate deployment. For instance, Indian millennials and Gen X show higher openness to AI agents compared to U.S. counterparts, while Chinese consumers exhibit greater tolerance for algorithmic mediation overall. This necessitates localisation strategies complying with region-specific regulations like GDPR in Europe and diverse consumer expectations across Asia-Pacific markets.

Looking forward, complete autonomous commerce—where AI agents access preferences, budgets, and calendars to make routine and complex purchases independently—raises challenging questions of oversight, liability, ethics, and digital equity. Who is accountable for mistakes or biased purchasing? Will AI agents prioritise partners paying higher commissions? How can less digitally connected populations avoid exclusion? These issues underscore the urgent need for governance, user education, and transparent frameworks.

Notably, OpenAI has open-sourced the ACP on GitHub to encourage community oversight and innovation. This transparency allows developers to audit security and propose enhancements, but industry observers caution that certification systems akin to PCI compliance in payment industry will be essential to regulate and ensure safe implementation.

For businesses entering agent commerce, experts recommend starting with low-risk categories, maintaining clear communication about AI roles and controls, ensuring consumer confirmation for purchases, educating users thoroughly, collaborating with regulators, and investing in fraud detection and customer support infrastructures. Brand trust and partnerships with reputable payment providers like Stripe and PayPal are critical assets.

In conclusion, OpenAI’s Instant Checkout represents more than a feature update—it is the dawn of delegated commerce, where conversational AI transcends advice to execute transactions seamlessly. Its success depends on balancing innovation with trust, transparency, and rigorous control mechanisms. As agent commerce matures, it promises to redefine shopping into a frictionless, AI-driven experience that could shift consumer behaviour dramatically. Companies prioritising trust as their primary currency—not just data—will shape this transformative new era, potentially making conversation itself the new checkout line.
