Nvidia Invests $1.5B in SoftBank Data Center Unit Behind OpenAI’s Ohio Project
Nvidia has committed $1.5 billion to SB Energy, a SoftBank-backed developer building AI infrastructure for OpenAI. The investment supports the construction of a data center campus near Cincinnati, though Nvidia is not confirmed as the sole hardware supplier. Related power projects and financial dynamics highlight the $
TL;DR: Nvidia invested $1.5 billion in SB Energy to support OpenAI’s massive Ohio data center project, which aims for up to 8 GW of capacity. This strategic move deepens ties between chipmakers and infrastructure developers as AI demands drive unprecedented energy consumption and construction costs.
Key facts
- Nvidia committed $1.5 billion to SB Energy, a SoftBank-backed developer building AI infrastructure for OpenAI’s Ohio project.
- The Ports-Pike data center campus near Cincinnati will scale from 4.25 GW to 8 GW capacity.
- SB Energy plans a 9.2 GW natural gas power plant on former DOE uranium enrichment land, part of a $33 billion project.
- Reports in mid-August 2026 suggested Nvidia might increase its investment to $3 billion, with half tied to an IPO.
- Construction costs for natural gas plants rose 66% over the past two years per BloombergNEF data.
Nvidia’s Strategic Stake in AI Infrastructure
Nvidia has announced a $1.5 billion investment in SB Energy, a data center developer backed by SoftBank and involved in OpenAI’s infrastructure expansion [1][2]. This move strengthens Nvidia’s financial and operational ties to one of the most ambitious AI projects underway in the United States. The investment is part of a broader effort to support the development of large-scale computing facilities required to train next-generation artificial intelligence models.
Infrastructure and Energy Plans
The Ports-Pike data center campus, located near Cincinnati, Ohio, is designed to scale from an initial capacity of 4.25 gigawatts (GW) to a maximum of 8 GW [1][2]. SB Energy plans to construct a dedicated natural gas power plant with a capacity of 9.2 GW on land previously used by the U.S. Department of Energy for uranium enrichment [1][2]. The project is estimated to cost $33 billion, making it one of the largest energy infrastructure developments in recent history.
However, reports from mid-August 2026 indicate that Nvidia was considering a larger $3 billion investment in SB Energy, with half of that amount potentially tied to an initial public offering (IPO) [8]. This suggests the final deal may evolve beyond the current $1.5 billion figure.
Financial and Market Context
The surge in AI infrastructure spending is driving significant market pressures. BloombergNEF reports that construction costs for natural gas power plants have risen by 66% over the past two years [1][2]. Analysts warn that as these massive facilities come online, they may compete with export markets for natural gas, potentially tripling prices in certain regions.
SoftBank previously sold $5.8 billion worth of Nvidia stock in November to fund other AI initiatives [1][2]. This sale underscores the financial interplay between major tech investors and chipmakers as AI infrastructure scales globally.
OpenAI’s Broader Expansion
In September 2025, OpenAI announced plans to build five new Stargate data centers in collaboration with Oracle and SoftBank, targeting a combined capacity of 7 gigawatts [7]. While this figure is lower than the 9.2 GW power plant planned for Ohio, it reflects a distributed strategy across multiple U.S. locations.
Earlier in January 2025, reports indicated that Reliance Industries in India was planning a 3-gigawatt data center [5]. However, this project is unrelated to the OpenAI-SoftBank-Oracle infrastructure pledge, which has not been independently verified as a $500 billion commitment. The source cited for that claim (Reliance in India) does not support assertions about U.S.-based funding pledges [5].
Financial Performance of Major AI Investors
Microsoft reported mixed results in its fiscal 2026 fourth quarter: it recorded a $3.2 billion gain from its investment in Anthropic, but marked down its stake in OpenAI by approximately $600 million for the same period [6]. Despite this quarterly adjustment, Microsoft still achieved a full-year gain of $5 billion from its AI investments, highlighting the complex financial dynamics among tech giants involved in AI development.
Clarifying Misconceptions
The claim that Nvidia is the sole supplier of compute infrastructure for OpenAI’s Ports-Pike facility is not supported by available evidence. While Nvidia is a key investor and likely a major provider of GPUs, OpenAI has historically used multi-vendor strategies, including AMD hardware [8]. The $105 billion figure cited in some reports refers to a credit guarantee provided to OpenAI for data center development through SB Energy, not a direct credit line to the Ports-Pike campus. Given that the total energy project is estimated at $33 billion, a $105 billion credit guarantee exceeds the scale of the physical infrastructure and appears inconsistent with standard financial practices.
Additionally, the 9.2 GW power plant capacity exceeds the maximum 8 GW data center load by over 15%, raising technical questions about energy efficiency and grid integration. While excess capacity may be intended for future expansion or regional supply, the mismatch between power generation and data center demand warrants further clarification.
Conclusion
Nvidia’s $1.5 billion investment in SB Energy reflects a deepening alignment between chipmakers and AI infrastructure developers. While the company is not confirmed as the sole hardware provider for OpenAI’s Ohio project, its financial stake ensures significant influence over the facility’s design and operations. As AI demands grow, so too do the scale and complexity of supporting infrastructure—raising critical questions about energy sourcing, cost efficiency, and long-term sustainability.
