About & Methodology
The AI Data Center Index is a source-backed public database tracking the physical infrastructure that powers large-scale AI. It exists to make the global compute buildout legible — not just to industry insiders, but to anyone trying to understand where AI infrastructure actually lives.

Bitter Research Nexus
AI Data Center Index is maintained by Bitter as an open auto-research instrument for the physical compute frontier: where AI infrastructure is being built, who controls it, and how the market is scaling.
Bitter starts from the Bitter Lesson: general methods that scale with compute, including search and learning, tend to win. Understanding the compute substrate is therefore strategic work, not trivia.
The index is built to remove human bottlenecks: public sources become normalized records, coverage checks, exports, and reports instead of one-off research notes.
Every entry requires at least one verifiable public source before it is published. Sources are linked on each facility page so readers can evaluate the evidence themselves.
Official press releases, SEC and regulatory filings, planning applications, power purchase agreements, and reporting from credible industry publications (Data Center Dynamics, Bloomberg, Reuters, The Information).
Rumors, anonymous tips, social media posts, or single-source blog speculation. If the only evidence is a LinkedIn post or an unattributed claim, the facility is not included until better evidence appears.
Where capacity or status data is approximate, the record says so. The coverage report shows which fields are missing across the full dataset.
Facility name, operating company, country, region, city, and geographic coordinates for map placement.
Selected public MW capacity, scoped where known as IT load, system power, facility power, program capacity, or another disclosed basis. Blank when no credible public capacity is available.
Operational, under construction, planned, or announced — plus dated milestones where available (announcement year, construction start, operational date).
Primary energy source (renewable, nuclear, gas, mixed) and AI workload type (training, inference, mixed) when disclosed.
Every entry links to the original announcements, filings, or reporting that substantiate it.
A facility is included if it is primarily designed for or significantly allocated to AI workloads (training, inference, or both) and has at least one verifiable public source. Traditional colocation and enterprise data centers are excluded unless they have a documented AI-specific allocation.
Megawatt values reflect the best publicly available number for each facility. Some operators report total site power, others report IT load, system power, grid connection, or program capacity. The index stores the selected figure with its capacity scope where known. Treat MW figures as directionally useful, not perfectly comparable across operators.
"Renewable" means the operator has a specific clean energy commitment (PPA, on-site generation, or 100% renewable matching) for that site. "Nuclear" means a direct nuclear power supply or signed nuclear PPA. "Mixed" means the facility draws from the local grid without a specific clean energy commitment. "Gas" means natural gas is the disclosed primary source.
Operational: facility is live and serving compute workloads.
Under construction: ground has been broken and construction is documented.
Planned: site acquired, permits filed, or detailed plans published.
Announced: operator has publicly stated intent but no construction evidence yet.
The index is updated continuously as new sources become available. There is no fixed publication schedule — when a new facility is announced or an existing entry has new information, it is added as soon as it can be sourced and verified.
The index depends on public disclosure. Facilities that have not been publicly announced or reported are not included. Coverage is strongest in North America and Europe; Southeast Asia, Africa, and Latin America are known gaps. The coverage transparency pages show exactly which fields and regions are incomplete.
All sources are cited inline on each facility page. Readers can evaluate source quality directly — the index does not ask for trust without evidence.
