SoftBank has sold its entire $5.83 billion stake in Nvidia as it shifts focus to investing in ChatGPT maker OpenAI.
What’s brewing: SoftBank also sold about 40 million T-Mobile shares between June and September 2025, earning around $9.17 billion. This sale is part of SoftBank’s larger plan to cash in on some of its investments and free up capital.
T-Mobile is one of the largest U.S. telecom companies, offering mobile services, wireless internet, and data plans. SoftBank became its second-largest shareholder after Sprint’s 2020 merger with T-Mobile, while Deutsche Telekom remains the majority owner.
SoftBank aims to bet on a series of huge investments aimed at turning the company into a critical player in AI.
Note: this isn’t SoftBank’s first time selling Nvidia shares. Its Vision Fund first invested about $4 billion in the chipmaker back in 2017, then sold everything by 2019.
Even after selling, SoftBank still works with Nvidia through its AI projects, including the massive $500 billion Stargate data center planned in the U.S.
