NVIDIA has made one of the largest capital-return announcements in its history, with its Board of Directors approving an additional $150 billion for the company's existing share repurchase program.
The move increases NVIDIA's total remaining share repurchase authorization to $235 billion, with the company expecting to execute the program through fiscal year 2028. NVIDIA described the latest authorization increase as the largest share repurchase authorization increase in history.
CEO and founder Jensen Huang said the company's growth is being driven by the continuing shift toward artificial intelligence and accelerated computing. He said NVIDIA's cash generation allows it to simultaneously invest in new technologies and return capital to shareholders.
The announcement comes as NVIDIA continues to benefit from massive demand for AI computing infrastructure. The company reported $96.2 billion in revenue for its second quarter of fiscal 2027, up 106% from the same quarter a year earlier.
Alongside the buyback announcement, NVIDIA introduced its Open Agent Safety Platform, targeting one of the emerging challenges in artificial intelligence: controlling autonomous AI agents as they perform increasingly complex tasks.
The platform combines open software with a reference system design intended to provide full-stack governance and security across AI-agent software, computing hardware and robotics systems.
A key component is NVIDIA OpenShell, open-source software that establishes a secure runtime boundary around AI agents. It is designed to monitor and control how agents execute tasks and can be extended to work with third-party computing platforms, including Arm and Intel systems.
The platform also includes NVIDIA Sentry, a watchdog system running on NVIDIA BlueField-4 DPUs. NVIDIA says Sentry can continuously monitor agent activity and quarantine an agent within milliseconds if it attempts to move beyond its defined software boundaries.
NVIDIA says more than 100 organizations are working with its agent-safety technologies. The ecosystem includes companies such as Anthropic, Cisco, Dell Technologies, JPMorganChase, Microsoft, Palantir, Palo Alto Networks, Salesforce, SAP, ServiceNow, Scale AI and SpaceXAI.
The initiative reflects a broader shift in AI development: as autonomous agents gain the ability to access tools, APIs, data and physical systems, companies are increasingly looking for security mechanisms that operate beyond the AI model itself.
NVIDIA's latest announcements therefore combine two major themes shaping the company: returning substantial capital to investors while building infrastructure for the next phase of AI and agentic computing.
