SoftBank seeks Tepco stake to power AI expansion
SoftBank targets Tepco stake as AI power needs climb

​SoftBank is seeking a stake in Tokyo Electric Power Co. as Masayoshi Son looks to secure the electricity needed for a larger push into artificial intelligence. The move shows how the AI race is shifting beyond chips and models to the power grids that will feed future data centers.

Highlights

  • SoftBank is seeking a stake in Tepco.
  • Power access is key to AI data centers.
  • Tepco is valued at about ¥759 billion.
  • SoftBank is also pursuing projects in the U.S. and France.

Son looks to Japan’s top utility

Son told shareholders on Wednesday that SoftBank’s telecom unit had put itself forward as a candidate to invest in Tepco, Japan’s biggest power utility. Bringing Tepco closer to SoftBank would help the group build AI data centers in Japan, Bloomberg reports.

Tepco has been seeking a capital tie-up as it tries to strengthen its finances and manage the long-running cost of cleaning up the wrecked Fukushima Dai-Ichi nuclear plant. The company asked potential partners for proposals earlier this year.

Power becomes an AI asset

The interest in Tepco fits Son’s broader AI strategy. SoftBank has been moving deeper into data centers, batteries, chips, and infrastructure as it tries to secure enough compute capacity for OpenAI and other large AI customers. At the shareholder meeting, Son described the AI race as increasingly dependent on physical infrastructure, including chips, electricity and data-center capacity.

SoftBank’s telecom unit is already working on plans to convert a factory in Osaka into a major production line for large-scale batteries. Son also said SoftBank is reviewing multiple sites in Texas for data center projects and expects substantial profits from a planned Ohio project that would channel $500 billion into 10 gigawatts of capacity.

The company has also outlined plans to invest as much as €75 billion, or about $85 billion, to build 5 gigawatts of AI data center capacity in France. That project is part of a broader attempt to turn SoftBank into a central player in the AI infrastructure layer, not just an investor in AI companies.

The new bottleneck for AI

SoftBank’s interest in Tepco underlines a hard reality for the AI boom: data centers need enormous amounts of reliable power. Access to electricity is becoming as important as access to advanced chips.

For SoftBank, a Tepco stake could support domestic AI infrastructure and reduce dependence on overseas data-center capacity. For Tepco, a capital partner could help fund its turnaround and Fukushima cleanup costs. The potential deal also shows why utilities are becoming more strategically valuable as AI companies compete for power, land, and grid access.
