Product Details

This case examines SoftBank Group’s strategy to build a vertically integrated “physical AI” platform combining semiconductor design, artificial intelligence, data-center infrastructure, and robotics. Through the perspective of portfolio manager Jennifer Dawn, the case evaluates CEO Masayoshi Son’s conviction-driven capital-allocation process, SoftBank’s mixed record in robotics and technology investing, and the financial risks created by large commitments to assets such as Arm, OpenAI, and ABB Robotics. The case asks whether SoftBank’s proposed physical AI stack can create durable value—or whether its complexity, leverage, governance concerns, and execution challenges will deepen the conglomerate’s valuation discount.

• Analyze Son’s investment strategy and his pursuit of a “physical AI stack.” • Examine the risks that Son’s strategy entails. • Understand Son’s investment philosophy and background. • Assess the AI ecosystem and, specifically, physical AI (i.e., robots able to understand/perceive and act on their own).
