AI data centers run on electricity - not code.
And SoftBank wants to own the company that makes it.
CEO Masayoshi Son told shareholders this week that the telecom unit is looking to buy a stake in Tokyo Electric Power Co. - known as Tepco - Japan's biggest power utility. The reason? AI ambitions that need reliable, cheap power.
Every new AI model needs a data center. Every data center needs power. Lots of it.
A single large data center can use as much electricity as a small city. As companies like SoftBank push deeper into AI, locking down a steady supply of energy becomes just as important as buying chips.
Son's solution: go straight to the source. A stake in Tepco would give SoftBank influence over the utility that keeps Japan's lights on - and, more importantly, the one that could power its future AI factories.

Tepco has its own reasons to say yes. The company is still dealing with the massive costs of cleaning up the Fukushima Dai-Ichi nuclear plant, which melted down in 2011.
Earlier this year, Tepco put out a call for potential partners - a capital tie-up that could help turn its business around. SoftBank, with its deep pockets and hunger for power, fits the bill.
It's a straightforward trade: SoftBank gets the electricity it needs. Tepco gets the money it needs.
This isn't SoftBank's only energy move. The group's telecom unit plans to turn a factory in Osaka into one of Japan's biggest production lines for large-scale batteries - the kind that store power for data centers.
If the Tepco deal goes through, SoftBank would control both the supply of electricity and the batteries that store it. That's a powerful position for a company betting big on AI.
US energy demand is already climbing as AI drives up the need for power. Japan could be next.
