Walmart Just Gave Markets an Nvidia Scare: Is the US Consumer Tapped Out?
Walmart (WMT) stock fell nearly 6% before Thursday’s opening bell, a drop worth roughly $50 billion in market value. A rare sales miss revealed the retailer’s slowest US growth in six years.
Markets treated it like an Nvidia scare. Walmart serves about 280 million customers and members every week. When its shoppers slow down, the rest of the US economy usually follows.
Why the Walmart Sales Miss Rattled Wall Street
US comparable sales, meaning sales at stores open at least a year, grew 2.6%. Wall Street expected more. Bloomberg noted it was Walmart’s weakest domestic pace since 2020.

The company’s own filing shows where the pain sits. Customer visits rose 1.5%, yet spending per trip grew just 1.1%. People still show up. They simply buy less.
Fuel costs explain part of the squeeze. AAA data puts the national gas average at $4.09 per gallon, up almost $1 from a year ago. Reuters reported that shoppers cut back as pump prices climbed.
Not every register slowed. Sam’s Club, Walmart’s membership warehouse chain, posted 4.4% comparable growth. Bulk-buying value hunters keep spending.
The headline numbers actually beat. Revenue reached $187.9 billion and adjusted earnings hit $0.81 per share, per the official release. Traders sold anyway. The one figure tied directly to consumer demand had disappointed.

The stakes reach far beyond one retailer. Consumer spending drives about two-thirds of US economic output. That makes Walmart a live feed on American wallets, much as Nvidia’s order book tracks the AI boom.
Tariff Refunds Flatter Profits While Masking the Pressure
Operating income jumped 28.8% to $9.4 billion. Tariff refunds did most of the lifting, adding 96 basis points to gross margin. Management plans to hand that money back through lower prices in the second half.
The outlook stays modest. Walmart guided third-quarter adjusted earnings of $0.62 to $0.64 per share, with constant-currency sales growth of 3% to 3.75%.
The macro backdrop makes the signal louder. Treasury yields sit near multi-decade highs as the $40 trillion US debt pile grows. That keeps credit cards and car loans expensive. Fresh signs of weak spending could shift Federal Reserve rate expectations before September.
Crypto traders are watching too. Falling yields helped power Thursday’s crypto market rally. Softer consumer data would add fuel to the easing trade.
Still, the consumer looks bent, not broken. Visits kept growing, eCommerce climbed 23%, and Walmart maintained its full-year outlook.
More retail earnings and the Fed’s September meeting will show whether shoppers are tapped out or just catching their breath.
