Colossus 2

The facility is at the full ~1 gigawatt, 550,000 GPU capacity that was planned as of mid-2025. The timing is based on the air-cooled condensers needing to be complete to handle this power capacity. On 2026-01-13, the third (presumed to be final) array of condensers was roughly at the stage that the first array of condensers was 3 months prior, in October. Based on that, we estimate it will be completed 3 months later, in April 2026. Other components can be completed in parallel to that, but we estimate about a month more will still be needed to put the finishing touches on the data center. That brings the estimated timing to May 2026.
