Nvidia added $150 billion to its share repurchase authorization, raising remaining capacity to $235 billion in what the company called its largest single buyback expansion. Management intends to deploy the full authorization by fiscal 2028, implying an accelerated pace of roughly $40 billion per quarter over the remaining 16 months, compared with about $20 billion in each of the past two quarters. Nvidia generated $69.9 billion in free cash flow and $74.4 billion in operating cash flow in the first six months of fiscal 2027, while reporting $46.1 billion returned to shareholders over that period. Chief Executive Jensen Huang tied the program to confidence in long-term opportunities in artificial intelligence and accelerated computing. Nvidia shares rose about 2% Monday and closed at $227.21 after trading near $230. At that price, its roughly 24.1 billion outstanding shares implied a market capitalization near $5.5 trillion, and the full authorization could buy back slightly more than 4% of shares at prevailing prices.
