Ownership tiers over time
Operating-capacity-weighted shares at each recorded snapshot. Dates are when the distribution was captured; the ownership evidence can be older.
43 snapshots weighted by operating capacity, from 2026-09-23 to 2026-11-04. 144 earlier snapshots weighted every recorded power figure and are listed under Snapshot values.
- Tier 1 — company has an SEC identifier or a parent linked through filing, registry or supply-chain data
- Tier 2 — parent linked through licensed ownership data
- Tier 3 — parent linked through other sources
- Tier 4 — company identified; parent unrecorded
- Data Gap — no company linked
Snapshot values
Displayed MW are rounded to two decimal places. Operating capacity counts operational records only; a snapshot taken before operating weighting began lists only the figure it recorded, every status summed. Download values (JSON) for the full inputs used to calculate the shares. Consecutive snapshots showing the same figures are listed once, under their first and last dates; the download keeps every date.

Sovereign programme
National AI Initiative & K-Chips Act
The 2025 supplementary-budget procurement allocated 13,136 GPUs across NHN Cloud, Kakao and Naver Cloud, with 10,456 reserved for government use. NHN Cloud announced completion of its 7,656 B200 system in May 2026; Kakao reported 2,040 GPUs installed and testing in December 2025 within its 2,424-GPU allocation. ZDNet Korea reported Naver’s 3,056 H200 system in operation in May 2026. Korea’s longer-term targets combine public acquisitions with private-company plans. A separate National AI Computing Center is planned at Haenam.
Partners: NVIDIA, Samsung Electronics, SK Group, Hyundai, MSIT, Naver, SK Telecom, LG, NCSoft, Upstage, KEPCO.

How the figures were made
Geography. Outlines use Natural Earth de facto boundaries. Distant parts may be omitted; located records outside the drawing are counted in its caption. Power circles use the same scale across countries.
Counts. Counts retrieved 4 Nov 2026. Operating capacity and ownership shares include estimated capacity; a campus figure recorded as its full build-out, earlier phases and second records are shown apart rather than counted. Sovereign programme ratios use government-only announced amounts where available; each ratio lists its numerator and denominator.
Corporate traceability. No company linked means no operator, site owner or hardware owner has been linked to the facility. The tiers do not verify property ownership or facility operation. Announced and under-construction figures are not counted here. Tiers classify the available sources for a company linked to each facility. A linked company’s SEC identifier can qualify it for the first tier without establishing a parent. Ownership relationships and their sources are listed on the facility and company pages.
Export-control posture. Recipient and end-use conditions can change the outcome of a transaction. Classification review: 17 Jul 2026. Access basis: 1.00. This value encodes destination-level access for the listed accelerators. The recipient or end use can still trigger a license requirement.
Bilateral supply-chain partners. Counts include every tracked relationship; no dollar amounts are published for them.
Organisations headquartered here. Across all industries; multiple identifiers may refer to the same company. The record lists 47 distinct organisations with qualifying market-capitalisation or linked-record evidence, after reviewing all public organisation rows for South Korea; the source holds 849 organisation rows, including duplicate identities and rows without qualifying evidence, and the company register applies its own evidence scope. A type is shown only where the classification has been reviewed. Market capitalisation: figures from companiesmarketcap.com, April 2026 (authority tier 3).
