Big Tech commits to pay for all AI power costs, but electricity shortage looms as infrastructure spending hits $660–$690 billion（約110兆円） in 2026.

What happened: In March, Microsoft, Google, Amazon, Meta, OpenAI, Oracle, and Elon Musk's xAI signed a White House agreement to cover all electricity and grid costs for their AI projects. The five biggest AI infrastructure providers plan to spend anywhere from $660 billion（約110兆円） to $690 billion（約110兆円） on capital expenditure in 2026.

Why it matters: Power is now the critical bottleneck for AI growth. A new utility-scale power plant takes five to ten years to build, while nuclear capacity takes even longer—Microsoft's Three Mile Island restart won't deliver electricity until 2027 at the earliest, and Google's Kairos Power reactor isn't expected online until 2030. This timeline mismatch means AI demand may outpace available power supply.

What to watch: Bitzero (NASDAQ: AIBZ) has already secured more than a gigawatt of low-cost power across Norway, Finland, and North Dakota, and just announced a major deal with a long-term tenant at their flagship site. The company controls power infrastructure that was secured years before the March announcement, in countries where building comparable capacity is no longer possible.
