August 31, 2026, (Inside AI) — OpenAI has received warrants valued at an estimated $5.5 billion in SB Energy, a power infrastructure firm, according to draft IPO documents reviewed by sources.
The warrants surfaced as part of SB Energy's preparations for a public listing. They signal a deepening financial link between the artificial intelligence leader and the energy sector that powers its data centers.
Neither OpenAI nor SB Energy responded to requests for comment. The warrants were disclosed in documents not yet public, and their exact terms remain unclear.
Energy Deals Anchor AI's Compute Expansion
The reported warrants follow a pattern of AI companies locking in access to electricity. Data centers for large language models consume massive power, and grid constraints have become a bottleneck for growth.
SB Energy, a subsidiary of Japan's SoftBank Group, operates renewable energy projects across the United States and India. It has positioned itself as a supplier of clean power to industrial customers.
OpenAI's interest in energy infrastructure is not new. The company has previously discussed partnerships to secure dedicated power for training and inference workloads.
Warrants give the holder the right to buy shares at a set price later. They often accompany strategic investments or long-term supply agreements.
The $5.5 billion figure represents the estimated value of those warrants, not cash spent. That distinction matters for understanding OpenAI's capital strategy.
Public Listing Brings AI-Energy Ties Into Focus
SB Energy's draft IPO documents reveal the warrants as part of its corporate structure. The company has not confirmed a listing date or valuation.
The energy sector has seen rising interest from technology firms. Microsoft, Google, and Amazon have all signed power purchase agreements to support cloud and AI operations.
OpenAI's reported warrants suggest a similar approach. They could convert into equity if SB Energy's stock performs well after the IPO.
Industry analysts note that AI's electricity demand is projected to grow sharply. Goldman Sachs estimates data center power use could double by 2030.
The warrants may also reflect a broader trend of AI companies taking direct stakes in energy assets. This reduces reliance on utilities and hedges against price volatility.
SB Energy has developed solar and wind projects totaling several gigawatts. Its portfolio includes large installations in Texas and California.
OpenAI has not disclosed its total energy commitments. The company's compute costs remain a closely watched metric for investors.
The draft documents reviewed by sources did not specify when the warrants were issued. They also did not reveal the exercise price or expiration date.
Public markets have been receptive to energy infrastructure listings. Investors seek stable cash flows from long-term power contracts.
For OpenAI, the warrants represent another tool in its infrastructure playbook. The company has also invested in nuclear fusion startups and advanced grid technologies.
The reported deal underscores how AI's resource needs are reshaping traditional industries. Energy, real estate, and semiconductors are now central to AI strategy.
SB Energy's IPO could provide more details on the warrants. Regulatory filings typically include full terms and conditions.
Until then, the $5.5 billion figure remains an estimate based on draft documents. The final value may shift with market conditions.
OpenAI's financial disclosures have been limited since its conversion to a capped-profit structure. The company does not publicly report detailed balance sheet items.
This opacity has fueled speculation about its capital expenditures. Energy warrants add another layer to that picture.
The AI industry's power consumption has drawn scrutiny from regulators. Some jurisdictions have imposed moratoriums on new data center construction.
OpenAI's move into energy warrants may preempt such constraints. Owning a stake in a power producer could secure priority access to electricity.
SB Energy's renewable focus aligns with corporate sustainability goals. Many AI firms have pledged to run on carbon-free energy by 2030.
The warrants could also be a financial investment. If SB Energy's stock rises after the IPO, OpenAI would profit from the equity upside.
That dual purpose makes the deal strategically flexible. It serves both operational needs and potential financial returns.
The source material did not include comments from named executives. No direct quotes were available for this report.
SB Energy's parent, SoftBank, has its own AI ambitions. The conglomerate has invested in multiple AI startups and infrastructure projects.
The relationship between SoftBank and OpenAI has grown closer in recent years. SoftBank led a funding round that valued OpenAI at $300 billion in 2025.
That context adds significance to the warrants. They may be part of a broader strategic alliance between the two organizations.
Energy analysts expect more AI companies to follow this path. Direct equity stakes in power assets are becoming a standard playbook.
The reported warrants, if confirmed, would be among the largest such deals in the AI sector. They highlight the scale of investment required to sustain AI growth.
