OpenAI Stargate Abilene

Land clearing begins for northern two buildings (Building 1-2)

Building 1 looks close to finishing construction, with chillers in place. OpenAI [stated](https://openai.com/index/five-new-stargate-sites/) that "Oracle began delivering the first NVIDIA GB200 racks in June." The "tenant improvement" work [is not due](https://www.tdlr.texas.gov/TABS/Search/Project/TABS2025000156) until September, however.

Building 1 is fully operational around this date. The first phase was "live" on September 30 according a Crusoe [announcement](https://www.crusoe.ai/resources/newsroom/crusoe-announces-flagship-abilene-data-center-is-live). While the first phase consists of Building 1 and 2, the language doesn't outright confirm that both buildings are fully operational. The announcement also stated that "Oracle began delivering the first NVIDIA GB200 racks in June", and we think 3 months is enough time to ram to 50,000 GB200s in Building 1. The satellite image also suggests that Building 1 is complete (shell and equipment done, many cars neatly parked) while Building 2 is ongoing (trucks and construction equipment still present). The 200 MW [substation](https://www.mortenson.com/projects/abilene-data-center-development) built in 2022 and expanded in 2024 is enough to power both buildings. To the right of Building 2, five gas turbines are in place with five more turbines still under construction. Chillers are partly installed for Building 3. Roof is complete for Building 4. The larger 1 GW substation is not complete yet.

Building 2 is fully operational. This exact date corresponds to the expected completion date of "Four (4) data hall spaces and an administrative office build-out" according to a [TDLR filing](https://www.tdlr.texas.gov/TABS/Search/Project/TABS2025007742), but this date is also consistent with satellite imagery. By January 15, Building 2 looked as finished as Building 1, whereas on September 26 it did not look finished.

The 1 GW substation looks close to completion. Building 3 appears to have all power and cooling equipment installed, but there are still signs of construction work. This seems on track for operation in 3 months. Building 4 has about 80% of chillers installed. Other buildings have few or no chillers installed.

Building 3 and 4 look complete, but are not fully operational. Not as many cars are parked next to it as Building 1-2 which suggests they may still be ramping up. Building 4 was due by now according to a [regulatory filing](https://www.tdlr.texas.gov/TABS/Search/Project/TABS2025014756). Building 5 still has light construction activity, while Building 6 still lacks chillers. The on-site power plant to the right of Building 2 looks complete.

Buildings 3 and 4 are estimated to be operational. On April 22nd, Oracle [posted](https://x.com/i/status/2047012589302153558) that "In Abilene, 200MW is already operational". This suggests that there was still only Building 1 and 2 operational. Since Buildings 3 and 4 looked complete from the outside on March 24th, we give it another month after Oracle's post for them to be operational. This would also give the buildings a similar 1 year 4 months timeline that Buildings 1 took from land clearing to being operational.

Buildings 5-8 are structurally complete and roofed but not yet confirmed operational (fit-out ongoing). The substation looks complete.

Buildings 5-6 are operational. On Oracle's Q1 FY27 earnings call (September 10, 2026), Clay Magouyrk said "6 of the 8 campus buildings, representing 618 megawatts and 75% of total capacity have now been delivered to the customer" ([transcript](https://www.fool.com/earnings/call-transcripts/2026/09/11/oracle-orcl-q1-2027-earnings-call-transcript/)). 618 MW = 6 x 103 MW, matching the per-building IT power figure Crusoe reported earlier. Since Oracle is the chip owner rather than the facility operator, we assume "delivered" means the chips are installed and ready to use.

Buildings 7-8 are estimated to be operational. On March 24, Building 8 roughly looked like where Building 3 was in September. Building 3 is estimated to be operational in April, 7 months later. This naively suggests Building 8 will be operational by early November, 7 months after March 24. Oracle gave no date for the last two buildings on its September 10 call.
