Mizuho has partnered with Nvidia to develop secure private AI environments, following a series of AI-related moves. In June 2026, the bank selected Oracle’s Autonomous AI Database running on Oracle Cloud Infrastructure, a move targeting roughly 66% reduction in database licensing costs, with automated patch management and monitoring for ransomware protection. Mizuho has also run internal AI programs, including the Mizuho AI Open competition, and struck a partnership with SoftBank focused on applying AI to transaction data analysis. Nvidia has been expanding its Confidential Computing capabilities, which allow AI workloads to process sensitive data without exposing it to the cloud provider, through partnerships with enterprises including VMware and Meta. Mizuho Securities, the brokerage arm, has named Nvidia as a top semiconductor pick for 2026, alongside Broadcom and Lumentum, and analysts at Mizuho have issued several price target increases for Nvidia throughout 2025 and 2026, citing surging demand for AI accelerator technologies.
