Aug 28 (Reuters) - The S&P 500 and Dow Jones Industrial Average notched record high closes on Thursday after Nvidia's quarterly report fell short of investors' high expectations but confirmed that spending related to artificial intelligence infrastructure remains strong.

Shares of Nvidia (NVDA.O), dipped 0.8% after Sino-U.S. trade uncertainties prompted the leading AI chip designer to exclude potential China sales from its quarterly forecast late on Wednesday.

Investors viewed Nvidia's report, including a 56% surge in quarterly revenue, as confirmation that demand related to AI technology remains strong, supporting a rally in AI-related stocks that has propelled Wall Street to record highs in recent years.

Other AI heavyweights gained, with Alphabet (GOOGL.O), adding 2%, Amazon (AMZN.O), up 1% and chipmaker Broadcom (AVGO.O), rising almost 3%.

"Nvidia is such an outlier that to say it was a disappointing print is only against the bar of borderline impossible expectations," said Ross Mayfield, an investment strategy analyst at Baird. "It's clear that the primary structural driver of this market, which is AI, is not going anywhere or cooling down."
