SoftBank Group is looking to boost its existing 11% stake in OpenAI to an even more substantial amount. Bloomberg reported that the Japan investment company is holding discussions about investing up to an additional $30 billion in the maker of ChatGPT.
OpenAI CEO Sam Altman has held early talks with investors for additional funding of at least $50 billion, which Bloomberg said would value the AI company at $750 billion to $830 billion.
SoftBank has a 11 per cent stake in OpenAI after making a $22.5 billion investment through its SoftBank Vision Fund 2 at the end of 2025. Earlier in 2025, it injected $7.5 billion into the US company and raised $11 billion from third-party investors.
In November, SoftBank Group chair Masayoshi Son said together with OpenAI “we’re driving the AI revolution to the next stage”.
Son stepped up its investments in 2025 across a range of sectors, reaching a deal in October to acquire ABB’s industrial robot business for $5.4 billion. In November it completed the $6.5 billion acquisition of Ampere Computing, a US-based chip designer. Around that time it also divested its full interest in Nvidia for $5.8 billion.
