Monex Group Forms Capital and Business Alliance with IRBANK
Monex Group, Inc. has entered into a share subscription agreement with IRBANK Inc. It’s the operator of Japan-based investment information service IRBANK. Monex Group plans to make IRBANK an equity-method affiliate and toughen collaboration between the two companies via this investment. The alliance strives to combine IRBANK's investment information and data capabilities with Monex Group's financial services infrastructure to develop new AI-powered investment and trading services.
Why this Partnership
IRBANK is one of Japan's top investment information services. It provides information on listed companies, including earnings, financial results and other corporate data. Also, it offers market information such as share prices, trading values and margin trading balances. Investors can use its time-series visualisations and company comparisons to analyse individual stocks from different perspectives. Since its launch in 2013, the platform has attracted a large individual investor base and currently has approximately one million monthly active users. In July 2026, IRBANK introduced an API/MCP server that lets AI tools access its investment information. It shows the company's efforts to develop investment information infrastructure for the AI era.
Monex Group sees the growing generative AI and AI agents adoption as an opportunity to change how individual investors research markets, analyse information, make investment decisions and execute trades. The company has already taken steps in this direction. In August 2026, its subsidiary, Monex Securities, became the first major securities firm to launch a ChatGPT plugin-compatible service called MONEX MCP Server. The service lets AI tools access information from Monex Securities brokerage accounts.
Monex Group believes that fusing these developments with IRBANK's investment data and AI-focused development capabilities can create new opportunities for individual investors. Its vaster objective is to develop an AI-native investment platform that connects research, analysis and trade execution on multiple asset classes.

The ambition is to create a seamless experience where investors can gather information, analyse investment opportunities and execute trades across different asset classes.
