Nomura stepped further into the AI race after signing a partnership with OpenAI aimed at developing new investment tools, market analysis systems and client services. The agreement marks one of the most direct moves by a major Japanese financial group to embed generative AI across its core businesses.

Bank to Adopt OpenAI Deep Research

Under the deal, Nomura will adopt OpenAI Deep Research and receive technical support as it builds new AI-powered services. The bank plans to combine its internal data with external datasets to deliver new forms of investment advice and analysis. It will deploy the tools while keeping its existing security and governance standards.

Nomura says generative AI now plays a central role in turning large datasets into usable information. The firm believes its long-standing data assets across asset management and other businesses will accelerate the rollout of AI solutions.

“Generative AI has the power to do more than boost efficiency. It can fundamentally transform financial services. Through our strategic collaboration with OpenAI, we will combine Nomura’s extensive data assets and deep expertise with state-of-the-art AI to deliver more advanced investment advice and market analysis,” commented Kentaro Okuda.

“By doing so, we will provide clients with more accessible and secure services, while also creating new revenue opportunities beyond traditional business models.”

OpenAI also framed the deal as a step toward wider AI adoption in finance. Tadao Nagasaki, President and CEO of OpenAI Japan GK, said generative AI “is rapidly becoming a critical foundation for transforming industries and society,” adding that the collaboration will help expand operational capabilities and support new services.

Partnership Part of Broader Strategy

Nomura said the collaboration aligns with its broader effort to merge human expertise with new technology. The bank plans to continue developing AI-driven tools as it looks to address challenges in global markets and expand the range of services it provides to clients.
