What changed
Grid constraints are pushing AI data center developers toward on-site and alternative power. Bloom Energy's first fuel cell power block is now live at Nebius's 300 MW New Jersey site, and Bloom expects sales to more than double this year. Vistra is a large utility beneficiary, and Caterpillar's record backlog points to demand for power equipment. IREN is licensing a planned 300MW data center in Spain. The power layer is a new and distinct leg of the AI buildout.
How this relates
Recent coverage adds a new development to this thesis — surfaced by cross-referencing fresh news against the existing catalog.
I read the Nebius and Bloom Energy fuel cell activation, Bloom's expectation of doubled sales, Vistra's valuation after a large multi-year run, IREN's European data center licensing, and Caterpillar's record backlog ahead of earnings. I grouped them as the enablers of power for AI capacity. The tree's AI infrastructure thesis covers chips, software and construction, and its hydrogen thesis centers on oil majors, so on-site power and equipment is a materially new development. That makes this an evolution of the infrastructure thesis rather than a duplicate.
