Nvidia board authorizes $150 billion buyback increase to $235 billion

Nvidia's board authorized a $150 billion increase to its share repurchase program, leaving $235 billion authorized, the company said Sept. 28, 2026. A buyback means the company buys its own shares, which can lift earnings per share by shrinking share count. Reuters called it the biggest-ever buyback plan. Authorization is capacity, not money already spent.
