OpenAI issued warrants worth $5.5 billion in SB Energy, WSJ reports

According to Business Recorder, the Wall Street Journal reported on Sunday that OpenAI was granted warrants estimated at $5.5 billion in SB Energy, a SoftBank unit that builds major power and data center schemes. The Journal based its account on draft IPO documents it reviewed. Reuters said it had yet to confirm the account independently, and neither company had responded to its requests for comment outside business hours.

The report also says SoftBank Group and OpenAI are set to be tenants in three SB Energy data centers. Earlier this month, Nvidia put $1.5 billion into SB Energy and agreed to guarantee up to $105 billion to support OpenAI's lease of an Ohio data center under construction. Reuters had also cited sources earlier this year saying SB Energy could seek a valuation above $50 billion in a market debut, possibly as soon as next month.
