QumulusAI / QumulusAI: Metro Atlanta data center site campus, August 2026

Announced Aug 20, 2026 · Up to 3.75 MW · Undisclosed

QumulusAI signed a seven-year colocation agreement for up to 3.75 MW in metropolitan Atlanta, conditional on the current occupant leaving. QumulusAI states a Q4 2026 ready-for-service target and says the site could support up to 2,048 B300-class GPUs. A right of first offer for up to 7 MW is not contracted capacity and is not included. The source does not say whether 3.75 MW is critical IT load or facility power. The later US$211.9 million customer agreement uses this site, but the MW basis remains unclear and the planned site amount is not a delivered customer allocation.

First-capacity target: Ready-for-service target Q4 2026, conditional on the current occupant transition; no completion evidence found
