Palantir Technologies (NASDAQ: PLTR) didn’t join the S&P 500 until September 2024. Here are three artificial intelligence (AI) stocks to buy in 2025 (listed alphabetically) that could be better picks than Palantir. Google parent Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) delivered an impressive gain of nearly 36% last year, although that return paled in comparison to Palantir’s. However, I suspect Alphabet could be a bigger winner in 2025 than Palantir for a few reasons.
