Reports indicate that SoftBank Group is preparing to make a significant new capital commitment to OpenAI. This move would represent a major escalation of the Japanese technology investor’s stake in the leading artificial intelligence firm, reinforcing its strategic pivot to become a dominant force within the AI sector.
A Strategic Pivot Fueled by Capital
The planned investment is far more than a simple portfolio addition. It underscores a deliberate strategic shift by founder Masayoshi Son toward artificial intelligence. In recent months, SoftBank has systematically streamlined its holdings, divesting from other technology investments
Currently, SoftBank is in negotiations to invest up to $30 billion in OpenAI. This financing would form part of a larger funding round that could raise as much as $100 billion for the developer of ChatGPT. Should this round proceed, it would catapult OpenAI’s valuation to approximately $830 billion.
Market Reaction and Existing Stakes
News of the potential deal provided a notable boost to SoftBank’s share price during Tokyo trading. If finalized, this transaction would substantially expand SoftBank’s already considerable involvement with the AI leader. The conglomerate had previously invested $22.5 billion in December 2025, securing an approximate 11 percent ownership stake.
Should investors sell immediately? Or is it worth buying SoftBank?
The timing of this potential capital infusion is critical. OpenAI is engaged in intense competition with tech giants like Google and requires vast sums to fund the training of its computationally intensive AI models. This fresh capital would be directed toward covering those costs and fortifying its market position.
Key Considerations for Investors
Several factors are now in focus for holders of SoftBank equity:
- The final confirmation and specific terms of the OpenAI investment will be pivotal for market direction.
- Arm Holdings, in which SoftBank maintains a major stake, stands to benefit from rising AI demand as a leading chip designer.
- SoftBank’s Q3 results for fiscal year 2025, scheduled for release on February 12, 2026, are expected to provide further insight into the company’s overarching strategy.
An $830 billion valuation for OpenAI would be exceptionally high. The ultimate success of this colossal wager hinges on OpenAI’s ability to maintain its technological edge against formidable rivals and to ensure the monetization of its AI models keeps pace with the immense investments required.
