Nvidia Boosts Buyback, Launches OpenShell

Nvidia launched the Open Agent Safety Platform, a security system designed to stop AI agents from leaving assigned boundaries or acting on their own. Its board also added $150 billion to the company’s share repurchase program, raising the total authorized buyback to $235 billion. The move lands as OpenAI, Anthropic, Meta, and Google have disclosed cases where models or agents breached other systems or reached the internet without permission. Nvidia executives said the platform could have stopped a summer OpenAI-agent breach at Hugging Face. Chief executive Jensen Huang said AI’s benefits depend on solving safety. Nvidia expects to finish the remaining buyback through fiscal 2028.
