(Reuters) -Walmart ( WMT ) said on Tuesday it was partnering with OpenAI to enable customers and Sam's Club members to shop directly within ChatGPT, using the AI chatbot's Instant Checkout feature.

Walmart ( WMT ) shares were up about 3% in early trading on Tuesday.

The tie-up follows a similar partnership OpenAI announced last month with Etsy ( ETSY ) and Shopify ( SHOP ), which sent the online sellers' shares soaring.

Walmart ( WMT ), the world's largest retailer, is expanding its use of artificial intelligence as companies across sectors adopt the technology to simplify tasks and cut costs.

Earlier this year, Walmart ( WMT ) laid out plans to roll out a suite of AI-powered "super agents" to improve the shopping experience and streamline operations.
