The AI boom is not just chips and chat windows. It is also power plants and the paperwork that ties them to the labs that need the electricity. Reuters reported on August 31, 2026 that the Wall Street Journal, citing draft IPO documents, said OpenAI was issued warrants worth an estimated $5.5 billion in SB Energy, a power infrastructure firm. Reuters could not immediately verify that report. SB Energy and OpenAI did not immediately respond to Reuters outside regular business hours.
A warrant is a coupon to buy stock later, usually at a set price. It is not cash in the bank today. If the Journal's read of the draft filings is right, OpenAI would have a large paper claim on a company that builds the juice and the buildings for AI data centers. That is a landlord handing the tenant a piece of the building company.
Reuters also laid out the nearby deals that make the number less random. Earlier this month Nvidia invested $1.5 billion in SB Energy and agreed to a guarantee of up to $105 billion to help OpenAI lease an SB Energy data center in Ohio. SoftBank Group and OpenAI are the planned tenants in three SB Energy data centers, the Journal report said. Reuters, citing sources earlier this year, said SB Energy could seek a valuation of more than $50 billion in its market debut.
I keep two facts in separate buckets. One: Nvidia putting money and a huge guarantee behind an OpenAI lease is already on the record from this month. Two: a $5.5 billion warrant package for OpenAI is a Journal claim that Reuters has not confirmed. Treat the second as reported, not as settled.
Why would a power company hand a lab a giant warrant? Because a tenant like OpenAI is the whole business case. Data centers only pay off if someone fills them for years. Giving the tenant a slice of the builder lines those bets up. If the IPO goes well, OpenAI's warrant is worth real money. If the build stalls, both sides hurt.
For regular people, this is the bill showing up as finance, not as a chatbot feature. The models you use sit in buildings that need a lot of power. Those buildings now come with stock coupons, chipmaker guarantees, and SoftBank as a roommate. When the same few names are the tenant, the investor, and the chip supplier, a wobble in one contract can rattle the rest.
The close is a filter. When you see a giant AI number this week, ask whether it is cash, a lease, a guarantee, or a warrant. A warrant worth $5.5 billion is not OpenAI spending $5.5 billion on electricity. It is a claim on a power company, reported by the Journal, not yet confirmed by Reuters. Keep that distinction. It is the difference between a bill and an option.
