Oct 14 (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 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.
