Mizuho teams with Nvidia to develop secure private AI environments

Mizuho has been on something of an AI acquisition spree. 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. That deployment is built around automated patch management and monitoring designed to strengthen ransomware protection.

The bank has also been running internal AI programs, including the Mizuho AI Open competition, and struck a partnership with SoftBank focused on applying artificial intelligence to transaction data analysis.

Nvidia has been expanding its Confidential Computing capabilities, technology that allows AI workloads to process sensitive data without exposing it, even to the cloud provider hosting the computation. The company has expanded these features through partnerships with enterprises including VMware and Meta.

Mizuho Securities, the brokerage arm of the financial group, has named Nvidia as a top semiconductor pick for 2026, alongside Broadcom and Lumentum. Analysts at Mizuho have issued several price target increases for Nvidia throughout 2025 and 2026, citing surging demand for AI accelerator technologies.
