Nvidia boosts stock buyback plan by $150 billion

Nvidia announced a $150 billion increase to its share buyback authorization, calling it the largest such expansion ever undertaken by a company. The move signals confidence from Nvidia's leadership in the company's financial position and long-term prospects amid continued demand for its AI chips.

Share buybacks allow companies to repurchase their own stock, often boosting share prices by reducing the number of shares outstanding. Nvidia has become one of the most valuable companies in the world, driven largely by demand for its graphics processing units used in AI training and data centers.
