Nvidia's record buyback and agent-safety push deepen its platform bid
Nvidia added $150 billion to its buyback, taking total authorization to $235 billion through fiscal 2028, and introduced an open agent-safety platform with more than 100 partners; OpenAI was not listed. Management describes minimal agent rights, sandboxing and monitoring. Bulls see cash-return confidence; skeptics, including Reddit holders, call the buyback defensive against vendor-financing fragility.
