SoftBank Group founder and CEO, Masayoshi Son, is reportedly planning to establish an ambitious $1 trillion industrial complex in Arizona, dedicated to the development and manufacturing of robots and artificial intelligence. This monumental project aims to re-establish high-end technology manufacturing within the United States, envisioning a hub that mirrors the vast industrial scale of China's Shenzhen.

The proposed venture, internally codenamed "Project Crystal Land," is seeking to collaborate with Taiwan Semiconductor Manufacturing Co. (TSMC), although the specific capacity of TSMC's involvement and its interest in the project remain unclear. TSMC is already heavily invested in the U.S., with plans to build chipmaking factories with a substantial investment of $165 billion.

In pursuit of this grand vision, SoftBank officials have engaged in discussions with various U.S. federal and state government bodies. These conversations have included talks with U.S. Secretary of Commerce Howard Lutnick, focusing on potential tax incentives and breaks for companies that would establish factories or invest within the proposed industrial park. Son is also reportedly gauging interest from other major tech entities, including Samsung Electronics.

However, the plans are still in their preliminary stages, and their feasibility is largely contingent upon securing robust support from the Trump administration and state officials. The sheer scale of the $1 trillion commitment underscores its significance, doubling the proposed $500 billion "Stargate" project. The "Stargate" initiative, backed by SoftBank, OpenAI, and Oracle, aims to significantly expand data center capacity across the U.S.

This potential new undertaking follows a series of other substantial investment announcements made by SoftBank this year. In March, the company declared its intention to acquire the U.S. semiconductor design firm Ampere for $6.5 billion. April saw SoftBank commit to underwriting up to $40 billion of new investment in OpenAI, with up to $10 billion of this sum intended for syndication to other investors. More recently, SoftBank successfully raised $4.8 billion through the sale of shares in T-Mobile. While SoftBank and TSMC have declined to comment on the Arizona complex, the White House and the U.S. Department of Commerce have not yet responded to requests for comment regarding the ambitious proposal.
