Anthropic’s Instacart Deal Looks Different From OpenAI’s. That Difference Is the Story

On April 23, 2026, Anthropic announced fifteen new consumer connectors for Claude, with Instacart in the batch alongside Spotify, Uber, Booking.com, and AllTrails. Anthropic’s own announcement, covered by Engadget and PYMNTS, said the Claude connector directory has grown to more than two hundred integrations since launching in July 2025, when its focus was workplace software.

What that arrangement looks like next to the deal Instacart did with OpenAI four and a half months earlier is the part worth examining.

Two AI assistants, two different deals

On December 8, 2025, Instacart launched a full end-to-end shopping app inside ChatGPT, complete with embedded checkout powered by Stripe and OpenAI’s Agentic Commerce Protocol, according to Instacart’s own announcement. Anirban Kundu, Instacart’s chief technology officer, said in that announcement that the integration was about turning conversations into real-world fulfillment, with payment happening inside the chat. The Claude integration takes a different shape. It builds a cart in conversation and hands it to the user’s Instacart account for completion, with no embedded transaction layer.

OpenAI’s transactional model has been walking itself back since launch. Retail Dive reported in March 2026 that OpenAI was shifting away from Instant Checkout toward retailer-controlled apps inside ChatGPT, with the company telling the publication that the initial version did not offer the flexibility it wanted. Walmart’s executive vice president of AI acceleration, Daniel Danker, told Retail Dive that the company’s Sparky agent would travel into ChatGPT and Gemini, with Walmart maintaining control of personalization, loyalty, and payment.

Anthropic, arriving five months later, structured the Instacart relationship as connector-first. Anthropic’s own communications, summarized in coverage from PYMNTS and Storyboard18, position Claude as carrying no advertising and no sponsored answers in conversations, with the assistant displaying multiple connected apps when more than one could help. For brand teams negotiating placement on AI surfaces, the implication is that placement and monetization rules already differ across assistants.

The same fulfillment network, licensed twice

Instacart’s December 2025 announcement described its network as covering more than 1,800 national, regional, and local retail banners across nearly 100,000 stores in North America. PYMNTS reported the catalog at more than two billion items and named the company’s Smart Shop personalization engine as the layer that adjusts to seasonal and household-level shifts. Digital Commerce 360 reported that the ChatGPT app pulls live local inventory and prices into the conversation. The same fulfillment network now sits underneath both Claude and ChatGPT, with Anthropic joining a list of AI partners that Kundu, in the OpenAI announcement, named as also including Google and Microsoft.

The traffic shift this sits inside

Independent data confirms the shift is already underway. Adobe Analytics found that traffic from AI-driven sources to ecommerce sites rose 758 percent year over year between November 1 and December 1, 2025, according to Digital Commerce 360. The same article cited Sensor Tower data, referenced by Bain & Company, showing that shopping-related queries inside ChatGPT on mobile rose from 7.8 percent to 9.8 percent of all searches between December 2024 and June 2025. Two integrations across two of the largest US AI assistants in five months, alongside Walmart redesigning its ChatGPT presence around Sparky, suggest grocery is taking on this shift earlier than most retail categories.

How this lands across brand and retail teams

Large CPG companies with mature retail media programs are watching how upstream cart-building affects the value of advertising on Instacart’s marketplace itself. Instacart’s Q4 2025 earnings call, reported by The Globe and Mail, disclosed that more than 9,000 brands advertised on the platform in the quarter, up from 7,000 a year earlier, with management projecting advertising revenue growth of 11 to 14 percent in 2026. If cart-building migrates to AI assistants where Anthropic has stated there are no paid placements, the marketplace’s ad inventory faces a structural question the platform has not yet had to answer.

Mid-market and emerging brands face a different problem. When an AI assistant builds a cart from a generic prompt, catalog accuracy and attribute completeness determine whether a product is included. Brand teams have less control over AI-mediated visibility than they had over retailer search.

Category managers and retail media buyers have the most concrete action item of the three. Data feeds, taxonomies, and commercial agreements between retailers, Instacart, and AI platforms are being negotiated now, and the version of those agreements that exists in a year will determine which brands appear on which assistants.

The connector-first model is closer to where consumers actually are

Anthropic shipped a connector that stops at the cart, five months after OpenAI shipped embedded checkout with Instacart and, later, Walmart. Visa survey data reported by Talk Business in November 2025 found that 67 percent of consumers across age groups would require human review for any chatbot transaction over a certain amount, and 61 percent wanted a way to halt a transaction in progress. PYMNTS additionally reported that Claude is designed to confirm with the user before completing any booking or purchase. The model Anthropic launched this week sits closer to those preferences than the original ChatGPT model did. Whether the next assistant to integrate with Instacart follows the connector model or returns to embedded checkout is the question worth tracking through the rest of 2026.
