SoftBank and OpenAI commit $1B to AI infrastructure expansion

SoftBank and OpenAI commit $1B to AI infrastructure expansion is profiled by BTW Media because published evidence links it to internet infrastructure, governance, operational dependencies, or market visibility.

• SoftBank Group and OpenAI have pledged a combined $1 billion investment into SB Energy to accelerate data centre and energy infrastructure for AI workloads.
• The funding supports the build-out of multi-gigawatt sites under the Stargate initiative, marking a strategic push to secure power and compute capacity for advanced AI development.

What happened: Joint funding for AI data-centre and energy build-out

SoftBank Group and OpenAI have announced a joint $1 billion investment into SB Energy, a company majority-owned by SoftBank that is pivoting from renewable energy into AI-focused data centre and power infrastructure. The announcement follows the strategic launch of the Stargate initiative, a multi-year, multi-hundred-billion-dollar programme aimed at building next-generation AI training and inference facilities across the United States.

Under the terms of the deal, both SoftBank and OpenAI are contributing $500 million each to fund SB Energy’s expansion as a developer and operator of large-scale data-centre campuses and associated energy systems. The initial build-out includes a 1.2 gigawatt data centre in Milam County, Texas, which SB Energy will operate and which is expected to begin service later this year.

OpenAI selected SB Energy to build and operate this facility, integrating its APIs and AI tools into operations, with SB Energy also becoming an internal customer of OpenAI’s services. The partnership is intended to ensure that power and compute resources keep pace with rapidly growing AI workloads.

SB Energy was originally focused on renewable energy generation and storage; in recent years it has broadened into data-centre construction to meet surging demand for reliable power and infrastructure. The involvement of major investors — including SoftBank and contributions from external backers — underscores the strategic value placed on energy and compute capacity in the AI ecosystem.

Why it’s important

The scale and direction of this investment highlight a critical bottleneck in AI expansion: power and infrastructure. As AI models grow in size and complexity, so do their demands for electricity, cooling and physical space. By investing directly in SB Energy, both SoftBank and OpenAI are attempting to control more of the supply chain, reducing reliance on third-party providers and enhancing resilience against shortages or grid constraints.

This move also reflects broader industry competition. Tech giants such as Meta, Google and Microsoft are likewise investing heavily in foundational infrastructure, sometimes in excess of tens of billions of dollars in data centre campuses and associated energy sources. Securing reliable infrastructure is not only a technical challenge but a strategic one as AI becomes central to economic and technological leadership.

The partnership may also shape how future AI infrastructure deals are structured, with energy providers evolving into key players in the AI value chain, and long-term power contracts or ownership stakes becoming standard parts of large-scale AI projects.
