Nvidia adds $150bn to share-buyback plan as AI-chip competition intensifies

Nvidia has approved an additional $150 billion for share repurchases, Reuters reported, expanding what it can spend on buybacks to roughly $235 billion through fiscal 2028. The move comes as competition in AI chips intensifies and investors scrutinize the sustainability of massive AI infrastructure spending. A buyback authorization allows purchases but does not guarantee the full amount will be spent immediately.
