OpenAI and SoftBank have committed $1 billion to SB Energy to expand AI-focused data centers in the U.S. The companies will each invest $500 million to fund construction and energy operations. This move strengthens SB Energy’s position in large-scale infrastructure development while advancing OpenAI’s data center strategy.
The investment targets SB Energy’s 1.2-gigawatt data center project in Milam County, Texas, as part of a broader U.S. buildout. The project aligns with OpenAI’s $500 billion Stargate initiative for AI infrastructure expansion. SB Energy will play a central role in powering high-capacity computing for the growing AI sector.
SoftBank has long supported SB Energy and now increases its stake to accelerate data center delivery. The company has built renewable energy projects and solar farms for major technology firms. The new investment allows SB Energy to integrate energy development with high-performance computing operations.
Strategic Partnership to Expand Data Center Capacity
SB Energy will operate multi-gigawatt data center campuses with backing from OpenAI and SoftBank. The partnership emphasizes speed, cost discipline, and integrated energy delivery across the U.S. The collaboration supports faster deployment of large-scale computing resources.
OpenAI selected SB Energy due to its expertise in energy infrastructure and data center development. The Milam County facility represents a key step in creating a reliable computing network. SB Energy will leverage its experience from previous renewable energy projects to optimize power efficiency.
The partnership is non-exclusive but formalizes preferred collaboration between OpenAI, SoftBank and SB Energy. Combined expertise ensures effective planning, construction, and operation of advanced data centers. It sets a model for future infrastructure projects across the United States.
Background on OpenAI, SoftBank and SB Energy
SoftBank originally founded SB Energy in 2019 to develop renewable energy and storage solutions. The company has since shifted focus to data centers and energy integration projects. This pivot positions SB Energy as a critical infrastructure partner for large-scale computing initiatives.
OpenAI has committed over $1.4 trillion in infrastructure deals recently to support the growing AI industry. The Stargate initiative aims to deploy multiple gigawatts of capacity across several U.S. sites. Meanwhile, OpenAI continues to rely on partnerships to scale operations and meet anticipated computing demand.
SoftBank’s recent financing rounds highlight its significant involvement with OpenAI and SB Energy. It has previously invested $41 billion in AI-focused deals and acquired related infrastructure assets. Consequently, the $1 billion investment reinforces a long-term strategy linking energy, data centers, and advanced computing.
