Nvidia increased its share-repurchase authorization by $150 billion, leaving $235 billion available for purchases through fiscal 2028, which ends in late January. The board's action follows an $80 billion addition four months earlier and exceeds Apple's $110 billion repurchase authorization announced in 2024. Chief Executive Officer Jensen Huang said the transition to AI and high-performance computing using GPUs is driving Nvidia's growth, while its cash generation supports both technology investment and shareholder returns. Nvidia benefits from the spending by major technology companies on AI data centers and servers, even as their infrastructure outlays have put pressure on free cash flow. Nvidia shares rose as much as 3.6% during trading on Sept. 28 and closed at $228.86, up 1.68% from the prior session. Its market capitalization exceeded $5.5 trillion, maintaining its position as the world's largest company. The stock traded at 16.5 times expected earnings over the next 12 months, below its roughly 30-times 15-year average. Nvidia is also advancing its position in the debate over open-source AI and agent safety. It agreed in September to spend $12.9 billion to acquire Hugging Face and introduced open-source software designed to monitor and control autonomous AI agents after recent agent-related hacks heightened safety concerns. Investors continue to assess AI-spending durability, valuation, margins, supply constraints, debt and the pace at which Nvidia deploys its buyback authority.
