Wall Street's main indexes rose on Thursday, as investors were relieved after data showed a still robust US economy, while Nvidia slipped as its largely in-line forecast failed to exceed lofty expectations for the AI chip firm.

A commerce department report showed the US economy grew faster than the initial estimates, amid strong consumer spending.

"The economy is not slipping into a recession anytime soon and that's beneficial for the stock market, along with a rate cut that's very likely coming in September," said Robert Pavlik, senior portfolio manager at Dakota Wealth.

Markets have seesawed between marginal gains and losses in the run-up to Nvidia's results, as traders waited to see if the company would sustain its unmatched revenue growth.

"This is the first time that there has been criticism of the estimates beat and the outlook raise. It is not as great as some investors had anticipated," said Peter Andersen, founder of Andersen Capital Management.

"Nvidia might be showing early signs of slowdown in capital expenditure for artificial intelligence."

Apple gained more than 2% after Citigroup selected the iPhone maker as its top AI pick over Nvidia. This helped the tech sector lead sectoral gains with a 0.9% rise.
