Walmart on Tuesday raised its annual sales and profit forecast for the third consecutive time, with people buying more groceries and merchandise online and at its stores, a sign that it may be gaining market share ahead of the holiday season.

Walmart said U.S. sales rose during the most recent quarter, propelled by shoppers buying groceries, home goods and toys—a sign that spending is off to a steady start this holiday season. The retail giant raised its sales and profit estimates for the year.

The retailer saw share gains in new shoppers across income levels mainly led by upper-income households, which make more than $100,000 in annual income, Walmart officials said during an earnings call on Tuesday. Walmart in a previous earnings call had also highlighted the rise in its higher income shoppers.
