SoftBank Boosts Nvidia, TSMC Stakes to Bet Big on AI Revolution

SoftBank Group is dramatically ramping up its investments in artificial intelligence by tripling its Nvidia stake to $3 billion and accumulating hundreds of millions in TSMC shares. The bold moves reflect Masayoshi Son’s conviction that AI will define the corporate and technological landscape for the coming decade.

Founder and CEO Masayoshi Son has clearly signaled SoftBank’s intent to secure a foothold atop the global AI infrastructure stack. The Japanese conglomerate’s timely acquisitions align with a broader goal: to surround its prized asset, Arm Holdings, with a powerful ecosystem of chipmakers, cloud hardware, and AI development partners.

Massive Nvidia Bet Underscores AI Ambitions

According to March 2025 filings, SoftBank tripled its investment in Nvidia, now the world’s most valuable chip company, to roughly $3 billion. Son’s team also acquired $330 million of TSMC shares, alongside $170 million in Oracle stock. The Vision Fund, SoftBank’s investment arm, continues to cycle positions for returns, showing no pressure from the parent company to rush sales.

Insiders and analysts see the acquisition as more than a passive bet. A top venture capital executive notes that Nvidia is at the forefront of the AI revolution. By increasing exposure to Nvidia, SoftBank hopes to gain greater strategic access to the chipmaker’s coveted hardware, essential for powering both AI models and cloud data centers.

Arm Holdings: The Linchpin of an AI Platform

Arm Holdings, the UK chip designer now 90% owned by Son, remains the centerpiece of this AI ecosystem push. SoftBank’s blueprint is clear: surround Arm with investments in suppliers and partners that control semiconductor production, cloud infrastructure, and major AI workflows.

This calculated approach follows a period where SoftBank missed out on the AI rally that sent Nvidia’s market value soaring past $4 trillion and TSMC near $1 trillion.

Project Crystal Land: Ambition Beyond Equity

SoftBank’s vision extends far beyond stock purchases. Son is championing 'Project Crystal Land,' an ambitious $1 trillion AI and robotics manufacturing complex proposed for Arizona, inspired by the manufacturing scale of Shenzhen, China. The project, still in early planning, aims to integrate TSMC, Samsung, and a network of global suppliers with advanced automation.

SoftBank representatives have already approached U.S. officials about incentives, but support from the Trump administration and private partners is key to breaking ground. If realized, Crystal Land could transform America’s high-tech supply chain and AI manufacturing capacity.

The Broader AI Infrastructure Push

These bold plans build on SoftBank’s January announcement of the $500 billion Stargate Project partnering with OpenAI, Oracle, and Abu Dhabi’s MGX fund to develop AI data centers across the U.S. Furthermore, SoftBank is ready to invest up to $40 billion in OpenAI, syndicating another $10 billion to institutional co-investors.

SoftBank’s Calculated Risk in a New AI Era

While some investors worry about over-concentration in a volatile sector, Son and his team remain convinced that the time to act is now. The combined equity stakes, strategic manufacturing ambitions, and Arm-centric network of alliances are designed to put SoftBank at the heart of the AI revolution both as an owner and an orchestrator.

SoftBank’s wager on Nvidia and TSMC is more than financial. If these bets succeed, they could help define how and where the next generation of AI breakthroughs happen worldwide, giving Son unique leverage in the next technology super-cycle.
