OpenAI was issued warrants worth an estimated $5.5 billion in SB Energy, reports Reuters, citing a Wall Street Journal report based on draft IPO documents reviewed by the Journal. Reuters said it could not immediately verify the report, and OpenAI and SB Energy did not immediately respond to requests for comment outside regular business hours.

Earlier this month, NVIDIA invested $1.5 billion in SB Energy and agreed to provide a guarantee of up to $105 billion to help OpenAI lease a data center in Ohio being developed by the company.

The Journal report said SoftBank Group Corp. and OpenAI are planned tenants in three SB Energy data centers. SB Energy could seek a valuation of more than $50 billion in a market debut that could come as early as next month.

SB Energy, a SoftBank subsidiary founded in 2019, develops large scale power and data center infrastructure projects.
