The capital pools stopped just financing the buildout and started OWNING it: BlackRock's GIP closed the $40B Aligned acquisition (with MGX/AIP), bought 80% of Meta's Hyperion, and ran the $12.5B El Paso bond; KKR launched the $10B Helix venture (Kuwait SWF + Nvidia + Vistra). One cohort thread, not one per manager. Track: who buys the next hyperscaler asset, the SWF co-investor pattern, and whether "locked" fiduciary capital keeps sliding into physical AI infra.
