By GlobalDataOpenAI’s contribution to the Stargate project is expected to be approximately $15bn.
According to several sources with direct knowledge of the deal, SoftBank’s equity investment in OpenAI could help cover latter’s commitment to the Stargate.
One person familiar with the matter was quoted by the publication as saying: “The talks are ongoing and the amount that SoftBank could invest in primary equity into OpenAI is a moving target.”
Microsoft, which first invested in OpenAI in 2019, currently holds the position of the startup’s largest shareholder.
OpenAI has amassed roughly $20bn through several funding rounds, leading to a valuation of $157bn in 2024. In the same year, SoftBank acquired a $2bn stake in OpenAI.
OpenAI CEO Sam Altman has been seeking to reduce the company’s reliance on Microsoft for computing resources.
This has led to initiatives such as developing proprietary chips and exploring partnerships with other cloud service providers such as Oracle.
As part of the Stargate deal, Microsoft has agreed to step down as OpenAI’s exclusive cloud service provider.
Insiders close to the negotiations suggest that approximately one-fifth of the total funding for Stargate is expected to come from equity investments.
Recently, Bloomberg reported that SoftBank was in discussions to spearhead a $500m funding round in AI robotics software startup Skild AI.
The funding round could elevate Skild AI’s valuation to $4bn, an increase from its $1.5bn valuation in 2024.
