SoftBank Group Corp., also known as SoftBank Group, is a Japanese multinational investment holding company and conglomerate led by its founder Masayoshi Son. Originally focused on software distribution, it has evolved into a global powerhouse primarily engaged in investment management within the technology sector, holding significant stakes in companies across internet services, semiconductors, telecommunications, and automation. Notable portfolio companies include Alibaba Group, where SoftBank was an early investor, and Arm Holdings, a leading semiconductor design firm.

The company's aggressive investment strategy is exemplified by its flagship vehicle, the Vision Fund, launched in 2017 as the world's largest technology-focused venture capital fund, managing over $100 billion in capital. Backed by investors such as Saudi Arabia's Public Investment Fund and other Middle Eastern sovereign wealth funds, the Vision Fund has invested billions into startups like Uber, DoorDash, WeWork, and FTX. The fund has faced scrutiny for high-profile losses and overvaluations, notably the WeWork collapse in 2019 which resulted in significant write-downs. Despite these challenges, SoftBank continues to shape global tech ecosystems through its funds and strategic partnerships, including consultations with firms like Goodwin Procter on foreign influence matters.

Headquartered in Tokyo, SoftBank's diverse business portfolio extends beyond investments to include telecommunications through its subsidiary SoftBank Corp., robotics via Boston Dynamics, as well as ventures in artificial intelligence and renewable energy. The company has faced criticism for its debt-fueled expansion and governance issues under Son's leadership, including allegations of aggressive accounting practices and regulatory investigations across various markets. Nevertheless, with a market capitalization in the hundreds of billions, SoftBank remains a pivotal force in international finance and technology networks, operating across multiple continents with an emphasis on disruptive innovation.
