The entire global installed base of data centers must be ripped out and replaced — legacy DCs unfit for AI factory workloads.

The entire global installed base of data centers must be ripped out and replaced — legacy DCs unfit for AI factory workloads. | Hyperscaler DC retirement + greenfield announcements

Key catalyst: Hyperscaler DC retirement + greenfield announcements

Watch events: Hyperscaler DC retirement announcements; liquid-cooling penetration rates.

Hyperscalers retiring >10-year-old DC capacity aggressively 2025-2026; liquid-cooling retrofits and high-density rack deployments accelerating.
