Nvidia earnings, Walmart sales to test AI boom and consumer resilience

The U.S. stock market’s twin pillars are about to face a hard test. Nvidia will report after the close on May 20, and Walmart will follow before the open on May 21, giving investors a close look at whether the AI trade and the consumer still have enough force to keep the rally intact.

That matters because the market has climbed back toward record territory, with the S&P 500 and Nasdaq Composite pushing into new highs in mid-May. Much of that advance has been concentrated in technology and chip stocks tied to data-center spending, AI training and the buildout of related infrastructure. Nvidia sits at the center of that trade as the world’s largest company by market value, and its shares have already risen 36% from the March low.

The Philadelphia Semiconductor Index has moved even more sharply, up more than 60% from that same low. That kind of move has fed concern that the market’s gains are becoming narrow, with a relatively small group of chip names carrying a disproportionate share of the advance. Investors are looking for evidence that Nvidia’s valuation is being supported by actual earnings strength, not just enthusiasm for artificial intelligence.

Wall Street’s expectations are high. Consensus earnings per share for Nvidia’s latest quarter is in the mid-$1.70s, setting a clear benchmark for a company that has become the symbol of the AI boom. The next report will also offer another read on whether the flood of spending by cloud and technology companies is still broad and durable, or starting to level off.

Retail earnings will test the other side of the market story. Walmart’s results on May 21 should show whether households are still spending enough to keep the economy moving, even with higher gasoline prices, elevated borrowing costs and stubborn inflation. Walmart chief financial officer John David Rainey has already flagged inflation, interest rates, tariffs and customer demand as factors that can materially affect results.

Home Depot, due to report on May 20, will add another reading on discretionary and home-improvement spending. Together, the week’s results could either reinforce the idea that AI and consumer resilience are still supporting U.S. stocks, or expose how dependent the market has become on a narrow set of winners and optimistic assumptions.
