Nokia (NYSE: NOK) has become an artificial intelligence play with a backer in Nvidia (NASDAQ: NVDA). In October 2025, Nvidia invested $1 billion in Nokia, taking a stake of roughly 3% and forging a partnership to build "the AI platform for 6G." The collaboration recently launched the first GPU-based AI-RAN system, aiming to roughly double the capacity an operator can squeeze from its spectrum, and T-Mobile US (NASDAQ: TMUS) has signed on as an early partner for 6G field trials. Throughout 2026, several Nokia insiders have been buying stock on the open market. New Chief Executive Officer Justin Hotard, who came from Intel's data center business, bought tens of thousands of shares this spring, and directors and senior executives followed.
