Nigam Arora returns to Market on Close to discuss some of the biggest tech moves he's watching in the market. He's impressed with Microsoft (MSFT) continuing to beat "very high" expectations in Azure cloud and Copilot. On Palantir (PLTR), Nigam outlines the company's path to reaching $1 trillion in market cap. While he sees the current price-to-sales ratio as unsustainable, he says Palantir is "so deeply embedded" in the U.S. government that it has a "sticky" source of revenue even if its commercial business wavers.
