SoftBank Group reported that during the period from April to December 2025, its investment in OpenAI generated a profit of 2.8 trillion yen (about 18.2 billion US dollars). This significant growth was mainly due to SoftBank's large-scale purchase of about 11% of OpenAI's shares for over 30 billion US dollars in 2025, successfully capturing the explosive growth in the artificial intelligence field.

Although the returns are substantial, SoftBank's aggressive expansion has also attracted market attention. Reports indicate that it is considering additional investments of up to 30 billion US dollars, which may cause its leverage ratio to reach the 35% downgrade warning line. Currently, SoftBank has solidified its leading position in the AI sector through this investment, achieving a transition from vision investment to tangible financial returns.
