In this piece, we will discuss the 15 Best AI Stocks to Watch in December 2025.
Amid rising valuations, increased capital spending, and cautionary signals from global investors and policymakers, the AI sector continues to draw attention. The intense competition that is shaping the sector was highlighted by Bill Gates, who spoke at Abu Dhabi Finance Week on November 8, 2025. He warned that not all companies with high valuations will end up as winners, even though he regards AI as “a deeply profound technology that will reshape the world.” While stating that “some of them will go down,” he reflected on the growing investor concern about overvaluations, which have taken some AI-focused stocks far beyond traditional price-to-earnings benchmarks.
Speaking to CNBC on November 8, 2025, BlackRock’s Ben Powell said the AI infrastructure ecosystem, including chipmakers and energy and copper-wire suppliers, will benefit most from ongoing investment. While discussing how hyperscalers are investing heavily to stay ahead in AI performance and offerings, driving what he called a “capex super boom,” he suggested that substantial gains may lie more with the underlying hardware and energy providers supporting the AI buildout than with the model developers themselves.
Meanwhile, European regulators urge caution. Concentrated exposure among U.S. hyperscalers, including Nvidia, Alphabet, Microsoft, and Meta, was highlighted in the European Central Bank’s 2025 Financial Stability Review, released in late November. While acknowledging that valuations are supported by strong earnings, it cautioned that market sentiment could change drastically if growth expectations stall. Noting a mix of FOMO-driven investment and solid earnings growth, strategists highlight the need for differentiation across AI picks.
With this backdrop in mind, we will jump to our list of the 15 Best AI Stocks to Watch in December 2025.

Reflecting mixed signals in the company’s growth trajectory, he pointed toward its Core HCM segment, which is expanding at a slower pace due to market saturation and intensifying competition, despite remaining Workday’s largest revenue driver.

At the same time, Simmons highlighted cross-selling and up-selling efforts, which remain strong contributors to bookings.
