Nvidia’s $150 billion buyback expansion is paired with an AI security system that can restrict agents and shut them down for rule violations.
The brief
Nvidia expands its share-buyback authorization to $150 billion while unveiling an AI security system designed to control agent access and shut agents down when they break rules.
The market roundup then turns to SK Hynix’s possible US IPO for Solidigm, its NAND-memory unit, which could seek a valuation of up to $100 billion.
SpaceX’s planned Starship 14 flight would deploy 26 Starlink V3 satellites and complete six orbits over ten hours before splashing down in the Pacific.
The episode closes by shifting from markets to urbanization, previewing how Dubai and other fast-growing cities might use AI and long-term infrastructure planning.
