OpenAI has reportedly received warrants valued at approximately $5.5 billion in SB Energy, highlighting the growing financial ties between artificial intelligence companies and the power and data center infrastructure businesses supporting their rapid expansion. The development was reported on August 31, 2026, based on draft initial public offering documents reviewed by the Wall Street Journal. The reported arrangement comes as OpenAI continues to secure large-scale computing and data center capacity needed to support increasingly demanding artificial intelligence workloads.
According to the report, the warrants issued to OpenAI are linked to SB Energy, a company focused on developing large-scale power infrastructure and data center projects. Warrants generally give their holder the right to acquire an ownership interest in a company at an agreed price, potentially allowing OpenAI to benefit if SB Energy’s valuation increases. The reported $5.5 billion figure therefore represents an estimated value associated with the warrants rather than an immediate cash payment to OpenAI.
The reported arrangement also illustrates how the economics of artificial intelligence are extending well beyond software and semiconductor companies. AI systems require enormous amounts of computing power, and that computing power depends on data centers with reliable access to electricity. As AI companies expand their operations, securing suitable sites, electricity supplies and specialized infrastructure has become an increasingly important part of their business strategy.
SB Energy has emerged as one of the companies positioned to benefit from this demand. Established in 2019, the SoftBank subsidiary develops large-scale energy and data center infrastructure. Its projects are aimed at supporting the growing electricity and computing requirements associated with AI and other technology-intensive workloads. The company’s role places it at an important intersection between the energy sector and the rapidly expanding AI industry.
The relationship between OpenAI and SB Energy has already attracted significant investment from other major technology players. Earlier in August, Nvidia invested $1.5 billion in SB Energy as part of a broader agreement connected to OpenAI’s data center requirements. Nvidia also agreed to provide a guarantee of up to $105 billion to support OpenAI’s lease of a data center in Ohio being developed by SB Energy.
That arrangement demonstrates the increasingly interconnected nature of the AI infrastructure market. Nvidia is one of the world’s leading suppliers of the high-performance processors used to train and operate advanced AI models, while OpenAI is among the companies generating enormous demand for those processors. SB Energy, meanwhile, provides infrastructure designed to house the computing systems and supply the power required to operate them at scale.
The Ohio data center project is particularly significant because large AI facilities require far more electricity than traditional data centers. AI workloads depend heavily on advanced processors that can consume substantial amounts of power, while the cooling systems needed to prevent this equipment from overheating add to overall energy requirements. As companies build increasingly powerful AI systems, infrastructure providers are therefore becoming central to the industry’s expansion.
OpenAI and SoftBank are reportedly expected to become tenants at three SB Energy data centers. Such arrangements could give OpenAI access to additional computing capacity while providing SB Energy with long-term demand from major technology companies. For infrastructure developers, commitments from large AI businesses can make massive projects easier to finance and plan because they provide greater visibility into future demand.
The reported warrants also come at an important moment for SB Energy as it prepares for a potential public listing. Reuters previously reported that the company could seek a valuation of more than $50 billion in a market debut, potentially as early as next month. If such a listing proceeds, the value of the warrants held by OpenAI could become an important point of interest for investors assessing the relationship between the two companies.
The potential IPO also reflects broader investor enthusiasm for companies positioned to benefit from the AI infrastructure boom. Over the past several years, attention around artificial intelligence has increasingly shifted from model development alone to the physical infrastructure required to support it. Data centers, electricity generation, transmission capacity, cooling systems and advanced semiconductor equipment have all become critical components of the AI ecosystem.
For OpenAI, obtaining an interest in an infrastructure company could offer advantages beyond simply securing data center capacity. If SB Energy grows alongside demand for AI infrastructure, an equity-linked position could potentially give OpenAI an economic benefit from that expansion. At the same time, the arrangement could strengthen the strategic relationship between OpenAI and a company responsible for developing facilities that support its future computing needs.
However, the reported valuation of the warrants should be viewed carefully. A headline figure of $5.5 billion does not necessarily mean that OpenAI has received $5.5 billion in cash or that the warrants can immediately be converted into that amount. The eventual economic value would depend on factors such as the terms of the warrants, SB Energy’s future valuation, market conditions and whether the relevant rights are exercised.
The development also raises questions about the financial structure emerging around the AI industry. As companies make increasingly large commitments to computing infrastructure, relationships between model developers, chip manufacturers, energy providers and data center operators are becoming more closely connected. Investments and guarantees can spread financial exposure across several companies, creating partnerships that are designed to support the enormous capital requirements of AI expansion.
For Nvidia, supporting infrastructure connected to OpenAI can potentially reinforce demand for its processors. For OpenAI, access to additional data center capacity is crucial as it develops and operates increasingly sophisticated AI models. For SB Energy, partnerships with companies at the center of the AI industry could help establish a strong customer base as it expands its infrastructure portfolio.
The scale of the reported figures also underscores just how expensive the next phase of AI development could become. Building a major data center requires significant investment not only in computing equipment but also in land, electricity connections, cooling systems, networking infrastructure and other supporting facilities. When several large projects are developed simultaneously, the capital requirements can quickly reach tens of billions of dollars.
