US equity indexes closed lower on Tuesday, led by declines in artificial intelligence-related entities, after comments from top executives and analysts raised concerns about artificial intelligence valuations.

* Wall Street leaders warned of potential market pullbacks as investors reconsidered high valuations in the technology sector, with Morgan Stanley's Ted Pick and Goldman Sachs' David Solomon citing likely sentiment shifts that could trigger 10% to 15% declines, Bloomberg and Reuters reported.

Shares of the $5.98 billion Global X AIQ ETF slid 3.3% amid reduced exposure to artificial intelligence plays, following Palantir's (PLTR) modest sales forecast and analyst concerns over overheated prices.

* Consumer confidence fell in early November as RealClearMarkets' monthly index dropped to 43.9, down from 48.3 in October, signaling a decline in sentiment heading into the holiday season.

* December West Texas Intermediate crude oil fell $0.59 to settle at $60.46 per barrel, while January Brent crude, the global benchmark, was last seen down $0.54 to $64.35.

* Expeditors International of Washington (EXPD) reported Q3 earnings Tuesday of $1.64 per diluted share and revenue of $2.89 billion, both higher than analysts' estimates. Shares rose nearly 11% following the report.

* Palantir (PLTR) raised its 2025 revenue outlook to between $4.396 billion and $4.4 billion, up from its prior range of $4.14 billion to $4.15 billion and ahead of market expectations, Bloomberg TV reported. Despite the higher forecast, the stock fell about 8.8%, one of the biggest losers on both the S&P 500 and the Nasdaq.
