Ownership chain not yet documented in the available data (licensed corporate-ownership database, licensed supply-chain database, SEC filings, LEI registry; as of 2026-06-12). The chain may extend further once additional ingestion runs complete; absence here reflects coverage at this snapshot, not a documented apex.
Description
xAI's Colossus supercluster complex in Memphis, TN. World's largest single-site AI training installation as of Jan 2026. Colossus 1 (Bldg 1): 100K H100, operational Sep 2024 in 122 days. Colossus 2 (Bldg 2): ~455K cumulative GPUs including GB200 Blackwell chips, crossed 1 GW threshold Jan 2026. Building 3 (Southaven, MS, nicknamed 'MACROHARDRR') purchased Dec 2025, conversion to data center began Q1 2026. Total planned capacity: 2 GW.

Notes
GPU breakdown is approximate. 555K total GPUs and $18B cost from SemiAnalysis/press reports (authority tier 3). 2 GW planned capacity from Musk announcement Dec 2025. Colossus 2 activated Jan 2026 as first gigawatt-scale AI cluster. Phase 1 100K H100 count verified by xAI. GB200 and H200 counts are estimates from industry reporting. Updated 2026-03-31.

flop_value_units_anomaly — Closure for val6-fac-xai-colossus-memphis-units-anomaly. peak_pflops_fp16 = 3.5e11 (= 350 ZFLOPS) was off by ~6 orders of magnitude relative to hardware-path estimate (~1.085M PFLOPS from gpu_inventory: 100K H100 + 100K H200 + 355K GB200). Per DQP §5 + F-31 root-cause investigation, value nulled in wave-13 (migration 20260619000000). The earlier DQF flag preserves the original observation; this row records the closure.flop_value_units_anomaly — Stored peak_pflops_fp16 = 350,000,000,000 (3.5e11 PFLOP/s = 3.5e26 FLOP/s) is off by approximately six orders of magnitude relative to a hardware-path estimate from the row's gpu_inventory: 100,000 H100 + 100,000 H200 + 355,000 GB200 → (100k×989.5 + 100k×989.5 + 355k×2,500) TFLOP/s ÷ 1,000 = ~1.085e6 PFLOP/s. The matcher consistently rejected this row in favor of the second xAI candidate (fac-epoch-xai-colossus-2 = 569,705 PFLOP/s) because the absolute distance from any Epoch row (1,375,000 max) is enormous, so this anomaly did not propagate into the killed comparison-table render — but it is incorrect at the consumption site (/facilities/fac-xai-colossus-memphis, /map pin tooltip, /cost-index $-per-PFLOP-day for xAI).United States (US)

No flags found across the chain (BIS Entity List, designation-cascade closures, or compute-threshold reporting obligations) as of 2026-06-12. Cascade closures evaluated: 0.
No ownership-change events documented in the available data for any entity in this chain over the last 5 years. Events draw from a licensed corporate-ownership database’s deal records (M&A, buyout, divestiture, asset sale, JV formation); coverage is strongest for private US/EU transactions and partial for state-owned-enterprise restructurings or non-Western private deals. Subsequent ingestion runs may add events here.

The walk for xAI Colossus Memphisstarts at the operator org id (or owner org id when no operator is recorded) and climbs upward through the unified affiliate graph, normalized to trace child-to-parent relationships. At each hop, the highest-authority parent edge wins (priority ordering: SEC EDGAR / 10-K / LEI registry > licensed corporate-ownership database > licensed supply-chain database > BIS / Federal Register > licensed affiliate graph). Confidence and recency break ties.
The walk terminates on (a) a node with a public-filing-grade ancestor edge — a SEC filer, an LEI-registered listed entity, or a 10-K-disclosed parent — (b) a government entity, (c) a 10-hop limit, or (d) a detected cycle. When termination is not at a public filer or government, the panel labels the chain's end-state as opaque beyond that point. Opacity is reported, never implied.
Per-source confidence (licensed corporate-ownership database): HIGH for Parent / Subsidiary edges; MEDIUM for JV and AFFILIATE edges. Known limitations: (1) shell companies with undisclosed principals terminate the public-record walk; (2) recent transactions reach the panel after the database's weekly refresh; (3) cross-jurisdiction private holding structures may carry intermediate hops that are not in any ingested source. Each row carries an edge-level as of date so freshness is auditable per hop.
Two further caveats are inherent to how the walker and the underlying data compose. The walker selects a single highest-authority parent per hop, so JV or multi-parent ownership structures collapse to one displayed path; alternate parents exist in the ingested sources but are not surfaced on this card. And some licensed-database edges encode parent-of relations against entity-resolved stub IDs whose display name reflects a sub-entity (a business unit, an acquired-then-renamed line) rather than the canonical parent — when a chain reads structurally surprising, the per-row source citation is the authoritative reference, not the chain's narrative shape.
Computed at: 2026-06-12. Walk depth observed: 1 hop. Sources combined: Scrutica facility record + licensed corporate-ownership database + SEC CIK cross-reference + LEI registry + (where applicable) licensed supply-chain database + Federal Register designation closures. The licensed databases are held under subscription and not redistributed; per-hop labels name no vendor.
