Nvidia Boosts Share Buyback by $150 Billion, Launches AI Agent Safety Platform
Nvidia authorized a record $150 billion increase to its share repurchase program and introduced a new security platform to prevent AI agents from going rogue, signaling confidence in its AI-driven growth.
The story
Nvidia announced a significant expansion of its capital return program, authorizing an additional $150 billion for share repurchases through January 2028, bringing the total remaining authorization to $235 billion.

The platform, which includes OpenShell software and Sentry technology, aims to enhance AI security during testing and deployment, with over 100 organizations, including Microsoft, reportedly using it. This dual announcement underscores Nvidia's financial strength and its proactive approach to AI safety as the technology continues to evolve.
