Nvidia has invested $3 billion in SB Energy shares ahead of SB Energy's anticipated $50 billion US IPO.

Nvidia is deepening its financial ties to the physical infrastructure powering artificial intelligence, beyond the chips themselves. The chipmaker has agreed to purchase an additional $1.5 billion worth of shares in SB Energy, the SoftBank-backed energy and data center company preparing for a US public listing. The move brings Nvidia's total equity commitment in SB Energy to $3 billion.

The fresh capital injection signals Nvidia's confidence in locking in its position before SB Energy reaches the public markets. Rather than waiting to participate in the offering itself, Nvidia has secured early positioning—a pattern that echoes similar moves across the chipmaker's AI supply chain strategy in recent quarters. The latest tranche consists of Class N non-voting shares, structured through a private placement paired with a prepaid forward contract, both priced at the same level as the public offering. This arrangement places Nvidia on equal financial footing with IPO investors while avoiding any governance influence over the company.

SB Energy is targeting a roughly $50 billion valuation and aims to raise between $5 billion and $7 billion through its Nasdaq listing under the ticker SBE. The company filed its IPO registration in late August 2026. Beyond the US offering, SB Energy is also seeking to raise $500 million separately from Japanese investors, with proceeds earmarked specifically for data center and power infrastructure development.

The centerpiece of SB Energy's operations is the PORTS-Pike Technology Campus located in Ohio, engineered to provide initial AI computing capacity of 4.25 gigawatts, expandable to 8 gigawatts. The campus is built specifically to handle the power demands of large-scale AI training and inference. It is primarily leased to OpenAI under a long-term agreement that mandates exclusive use of Nvidia chips—meaning every watt of computing power flowing through PORTS-Pike is directly tied to Nvidia's GPU business, giving the chipmaker a built-in commercial return on its equity stake.

Nvidia's involvement extends beyond equity ownership. In connection with the Ohio project, the company has pledged residual value guarantees reaching as high as $105 billion, situated within a broader $108.5 billion maximum gross exposure Nvidia disclosed in its latest filing covering AI infrastructure commitments. According to reports, Nvidia's obligations are expected to increase as nine data centers enter service beginning around fiscal 2029, before declining as OpenAI makes lease payments. The guarantee is triggered only under specified circumstances such as tenant default or insolvency, which limits its immediate financial impact without removing the exposure entirely.

SB Energy's financial trajectory reflects the capital intensity of the business. During the first half of 2026, revenue climbed 66.4% compared to the prior year, driven by surging demand for AI-grade data center capacity, while net losses grew larger over that same span. For investors watching the offering, the revenue trajectory offers reassurance that demand for AI computing capacity remains strong, though the widening losses underscore the reality that building gigawatt-scale capacity carries substantial construction costs and financing obligations that must be weighed against incoming lease revenue.
