SB Energy grants OpenAI warrants valued at $5.5 billion ahead of its upcoming IPO.

SB Energy is building and operating a 1.2 gigawatt data center in Milan County, Texas, for OpenAI.
The PORTS-Pike project in Pike County, Ohio is a data center park where SB Energy will build, own, and operate it; OpenAI will lease about 8 IT gigawatts under a roughly 20-year arrangement, with the park running on NVIDIA's computing stack.
OpenAI and SoftBank each invested $500 million into SB Energy in January 2026, tying the company into the Stargate executive layer.
The current SB Energy customer base largely consists of companies that are also investors in the firm, signaling a tight-knit ecosystem among backers and users.
Analyst Spiros Margaris notes the persistent pattern of blurred lines between investors, customers, and partners in these mega AI deals, highlighting evolving financial dynamics in AI infrastructure.
SB Energy, SoftBank's data-center arm, granted OpenAI warrants valued at approximately $5.5 billion as part of pre-IPO arrangements to secure the AI company as a major tenant Trading Key. The move highlights how Wall Street Journal reports SB Energy is preparing to file for an IPO as soon as this week, targeting $5 billion to $7 billion in funding.
The warrant grant underscores a growing pattern in AI infrastructure: the same companies that invest in data-center firms also become their biggest customers. GuruFocus notes this creates a tight-knit ecosystem where investors, customers, and partners overlap significantly.
SB Energy is building and operating a 1.2 gigawatt data center in Milan County, Texas, exclusively for OpenAI. The company is also developing the PORTS-Pike project in Pike County, Ohio, where OpenAI will lease approximately 8 IT gigawatts under a roughly 20-year agreement Trading Key. Both facilities will run on Nvidia's computing stack.
Nvidia invested $1.5 billion in SB Energy and provided financial guarantees to support a data center lease in Ohio Economic Times. This move deepens Nvidia's ties to the infrastructure backing its AI chips. The investment signals how chip makers are securing demand by funding the very buildings that house their hardware.
In January 2026, OpenAI and SoftBank each invested $500 million into SB Energy, tying the company into SoftBank's Stargate executive layer Trading Key. This dual investment by landlord and tenant creates financial interdependency that shapes how deals are structured and valued.
Analyst Spiros Margaris observes a persistent pattern in mega AI infrastructure deals: the same firms invest in data-center operators, lease their capacity, and negotiate warrants. GuruFocus reports that SB Energy's current customer base largely consists of companies that also invested in the firm. This overlap raises questions about fair pricing, competitive neutrality, and market dynamics as AI infrastructure consolidates.
