Palantir shares surged to an all-time high Thursday, extending gains earlier in the week after the company gave a stronger-than-expected outlook on growing demand for its Artificial Intelligence Platform.

Palantir Technologies (NASDAQ: PLTR) was the best-performing member of the S&P 500 (SNPINDEX: ^GSPC) last year. The stock has advanced 49% in 2025 as of Feb. 11, such that Palantir is once again the best-performing member of the S&P 500.

For the better part of the last two-plus years, the bulls have been in control on Wall Street. The mature stock-fueled Dow Jones Industrial Average, broad-based S&P 500, and growth-focused Nasdaq Composite have all reached numerous record-closing highs.
