NBIS Data Center Buildout Trackers

Summary

Best independent sources for monitoring Nebius’s physical data-center expansion:

Source	Best use	Caveat
Nebius Live Capacity Tracker — @SMASIMHO	Fast interactive map, site capacity, status, historical timeline and financial views. Underlying data are source-linked.	Maintainer is openly 100% long NBIS; some MW figures are inferred. Last GitHub data update found: June 24, 2026.
Northwise Nebius Infrastructure Map — @InvestNorthwise	Best site-by-site research, including power arrangements, construction phases and quarterly energization modeling.	Some future capacity and timing are modeled rather than confirmed.
Nebius Construction Monitor — RikardV	Clean snapshot of sites, MW, partners, delivery dates and permitting risks.	Appears stale: last visible update/commit was May 4, 2026.
Tilebox Data Center Buildout Tracker	Independent satellite-image check on visible construction at Nebius-related U.S. sites in Alabama, New Jersey and Missouri.	Measures surface change, not energized or revenue-producing capacity.
Baxtel Nebius Map	Industry cross-check of operating, construction and planned facilities.	Detailed capacity data are partly paywalled.

Bottom line

Use SMASIMHO for the dashboard, Northwise for detailed diligence, and Tilebox for independent physical verification. Do not treat contracted or planned MW as connected, energized or monetized MW; that conversion is the central NBIS execution variable.Research checked July 30, 2026.
