Anchor site of the Stargate programme in Abilene, Texas, operated by Oracle with OpenAI as tenant.
What is established
Partially operational. 200 MW confirmed energized (basis not stated by the source); expected Dec 2026; owned or developed by Oracle; tenant: OpenAI; power source: Grid + on-site gas turbines.
What is not disclosed
Accelerator count, project capex, cooling technology — not disclosed by any source on this page. Recorded as unknown, never as zero.
Analyst note
Gas turbines rated up to ~300 MW are reported on site, bridging the gap while grid capacity is built. CORRECTION 2026-08-01: the previous 300 MW confirmed figure was Epoch's April total-facility-power estimate, which Epoch itself revised. Oracle stated 'In Abilene, 200MW is already operational' (April 2026) — that operator statement is what the confirmed column now carries. Epoch's live directory estimates 421 MW IT across Buildings 1–4 (May 2026), projecting 843 MW / all eight buildings by ~November 2026; recorded as a separate estimate. OpenAI capped the site at 1.2 GW in March 2026.
Corroborated by more than one source, but not yet backed by physical evidence.

Operating capacity confirmed
A source states capacity that is energized and serving load.
