SoftBank Founder Pitches $1 Trillion AI and Robotics Hub in Arizona

PHOENIX, June 23, 2025 — Masayoshi Son, the billionaire founder of SoftBank Group Corp., has unveiled an ambitious plan to develop a $1 trillion industrial complex in Arizona, aiming to transform the state into a global hub for artificial intelligence (AI) and robotics manufacturing. Dubbed "Project Crystal Land," the initiative seeks to replicate the scale and innovation of China’s Shenzhen manufacturing hub, bringing high-tech production back to the United States, according to sources familiar with the matter.

Son is actively seeking partnerships with major tech players, notably Taiwan Semiconductor Manufacturing Co. (TSMC), to realize this ambitious vision. The proposed complex would house production lines for AI-powered industrial robots and potentially include facilities for SoftBank-backed startups, such as robotics firm Agile Robots SE, as part of its Vision Fund portfolio. Discussions are also underway with South Korea’s Samsung Electronics Co. and U.S. government officials, including Commerce Secretary Howard Lutnick, to secure tax incentives and support for companies investing in the industrial park.

The project’s estimated $1 trillion price tag dwarfs SoftBank’s recent investments, including its $19 billion contribution to the $500 billion "Stargate" AI data center initiative alongside OpenAI and Oracle. SoftBank is exploring project-based financing models, similar to those used in large infrastructure projects, to minimize upfront capital demands while leveraging its $23 billion liquidity and stakes in assets like Arm Holdings, which are valued at $176.46 billion.

Industry experts have expressed both intrigue and skepticism about the plan’s feasibility.

Melissa Otto, head of research at Visible Alpha, told Bloomberg that fostering partnerships between manufacturers, AI engineers, and specialized startups might be a more cost-efficient approach to advancing AI than building massive complexes. However, she noted that investments in data centers could lower AI development costs and drive broader adoption in the long term. Critics also point to Son’s history of ambitious proposals that sometimes falter, citing the need for substantial regulatory and industry backing to bring Project Crystal Land to fruition.

TSMC, a key target for collaboration due to its expertise in producing advanced AI chips for companies like Nvidia, remains noncommittal. The chipmaker is already investing $165 billion in Arizona facilities, including a factory that began mass production in 2025, but sources indicate its current plans are unrelated to SoftBank’s proposal. SoftBank and TSMC declined to comment, and the White House and U.S. Department of Commerce did not immediately respond to inquiries.

The announcement has sparked optimism in financial markets, with SoftBank’s shares rising 2.7% and TSMC’s stock climbing 1.9% on June 20, 2025. If successful, Project Crystal Land could reshape Arizona’s economy and bolster U.S. technological sovereignty, though its scale and complexity present significant challenges.

Son’s vision aligns with his long-standing commitment to accelerating AI development, as evidenced by SoftBank’s recent moves, including a $6.5 billion acquisition of U.S. semiconductor firm Ampere Computing and a $40 billion investment in OpenAI. As discussions progress, the tech world watches closely to see if Project Crystal Land will become a cornerstone of America’s AI future or remain a bold but unrealized dream.
