What changed

Building 2 is operational assuming a 3 month lag compared to Building 1.

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.

Building 2 (AKA CB4) is operational. On February 26, Terawulf stated that CB4 was expected to be energized by Q3 2026.

Building 2 (a tent like building) is operational. Based on a default estimate of 3 months for fit-out after structural completion in July.

Buildings 1–3 look externally complete, with the air-cooled chillers fully installed, and surrounding yard work cleared. The many cars and trucks parked beside the buildings suggest commissioning is still underway, so we’re not counting any buildings operational yet. Buildings 4-6 shells appear complete, and Building 7 is nearly 90% roofed. This is based on high-resolution satellite imagery from this date.

Buildings 17-18 are operational. This is an estimate based on a rule of thumb of "operational 5 months after roof is complete", assuming the roofs took one more month after 2025-12-23. Also added four more months to account for commissioning and adjacent cooling units not being complete yet.

Building 3 is operational. Based on the stated completion date in this regulatory filing

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). 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.

Building 2 is operational, confirmed via RAAD drone imagery of spinning cooling tower fans on September 8th.

Buildings 1-5 shells complete and fully roofed. Buildings 1-3 appear to be actively installing cooling and backup generators nearby. The pads for Buildings 6-10 to the north have also been visibly cleared, with foundations for Buildings 6 and 7 underway.

Building 8 interior fit-out scheduled to begin. TDLR project TABS2026028247 schedules a $110M interior fit-out of the existing 27,678.22 sq ft Building A as a data hall beginning September 1, 2026.

Buildings 7-10 (tents) are operational, based on infrared drone video from RAAD (raad.com) captured on this date. The video suggests that 138.8 MW of nameplate turbine capacity is operating at the Socrates South power plant (about 69% of the 200 MW nameplate capacity), and Buildings 7-10 roof vents are bright on infrared while Buildings 11-12 vents are not. That's 4/6 buildings operating, implying about 67% of capacity, which is consistent with 69% of the power plant operating. In the north, Buildings 16-27 (tents) look to be in a completed state. Each northern set of 6 tents still awaits to be connected to one of the corresponding power plants to become operational. Drone video from August 19th shows no turbines operating at Socrates North, though there are 3 small diesel generators operating. Building 13 (Vantage) is still under construction, we estimate another 3 months before operability.

Building 1 operational at full capacity. This is based on "Phase I", which is expected to be operational by the end of the first half of 2026. We added two months of overhead to account for remaining construction and/or installation of CoreWeave's chips, since the June 17 image still showed active minor construction around the building.

Building 1 is operational, based on a lack of construction activity around the shell and cooling equipment, and about 6 months passing after structural completion.

Building 2 has all cooling towers installed and is likely undergoing fit-out and commissioning. So we give it about 3 more months until it's operational. Building 3 appears to be slightly further than Building 2 was in March, so we estimate a 4-month lag.

Building 2 is operational. This is estimated based on the close-to-complete construction status from May 2026.

Building 1 is confirmed operational via drone imagery with 8/9 group of coolers with spinning fans. Imagery also confirms all cooling and power infrastructure in place for Building 2.

Confirmation that Building 4 is complete. Building 5 has progressed since February, with a complete roof, all backup generators in place, and five cooling towers in place.

Building 1 is operational (estimate).

Building 1 operational. Estimated based on present construction progress and typical timelines.

Building 3 expected to come online sometime around August 2026, since in the May satellite image it appeared structurally complete with minimal construction surrounding it. Basing MW estimate using Building 2 as a reference.

Building 1 shell is complete, with rooftop units installed, and most air-cooled chillers in place in a ground yard to the north. Most of the 120 backup diesel generators are also in place. Substantial progress since Nov 2025, still under construction and not yet energized.

Roofs of Buildings 1 and 2 are more than halfway complete. All chillers for both buildings are visible. Construction on Buildings 3 and 4 has begun, with outlines laid. Construction on the Apollo Power Generation Project (a BTM power plant built just to the east of the data center) is in progress, with foundations poured and generation equipment being set in place.

Active construction visible on and around the datacenter, with the roofing mostly in place. This is based on satellite imagery. No buildings operational yet.

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

Building 2 (a tent-like building) shell is complete, but we don't believe it's operational because there is unpaved ground, no cars parked right in front, the first tent buildings at Meta Prometheus took about 16 months (it's been 10 months for this building). North-west of Building 1, the outline of a building of similar dimensions and style to Meta Jeffersonville's Building 1 is visible, this is labeled as Building 3. West of Building 1 we see more land clearing for what could be a building similar to Meta Jeffersonville's Building 2.

Both buildings estimated to be operational.

Construction continues, Buildings 1 and 2 appear roughly halfway roofed, and building 3 foundation is halfway done.

Building 1 looks complete, consistent with it going operational back in May. Building 2 is mostly complete, with the row of backup generators on the east side of the building still being installed. Building 3 shell is complete, with rooftop coolers midway through installation, and no neighboring generators installed/visible yet.

Both buildings still operational according to satellite imagery.

Cooling install continues on the roof, satellite imagery indicates that not all units have been completed. Continued presence of construction vehicles and unfinished land on the campus suggests that the building is not operational yet.

Compared with the April 2026 image, the building shell is closer to completion, and several additional air-cooled chillers have appeared on the ground, though they do not yet appear to be connected or operating. We therefore keep IT capacity at 50 MW.

No significant change to the building since the August 2025 image.

Building 3 is operational. 7 cooling towers were finally installed despite being more spread out compared to the first two buildings. Cooling towers models vary slightly between buildings. Ground clearing to the southwest seems to be setting up for two more buildings.

Buildings 1-7 are operational and running, with no construction work visible. This is based on both satellite imagery, and the Q2 2026 Earnings call stating the campus was operational by midyear 2026.

Estimated full completion of the expanded row of cooling towers and backup generators for Building 1.

Building 3 is operational (estimate). Based on there being minimal construction work as of May 15.

According to satellite imagery, Building 2 is fully roofed and shell complete, with rooftop chillers mostly installed. Building 3 construction is well underway, with about 1/4 of the roofing done and the foundation laid out.

Construction has advanced significantly since February 2026. We observe extensive earthworks and multiple graded building pads across the campus, with structural work underway on the main data center buildings. A large solar array and water storage basins are visible on site, and two cleared areas on the western side of the campus, likely for on-site power generation. No buildings appear operational yet (no completed roofs or signs of active cooling), consistent with the projected 2028 completion.

Buildings 1 and 2 are estimated to be operational.

We estimate Buildings 1 and 2 are operational.

Building 1 appears externally complete and likely Ready for Service, with all cooling/roofing/generators in place, but we're not labeling it operational yet due to visible surrounding yard/construction work. CoreWeave likely still needs time to install chips and use all their designated chip capacity. The pad to the northeast has foundations being laid out for Building 2.

No notable changes since October.

Building 1 is operational, based off of colored motion artifacts from cooling towers and direct visual verification.

The site is estimated to have at least ~830 MW of GPU server power, with at least "at least 220,000 additional GB300 processors and over 400 additional megawatts of compute power", corresponding to the "next phase of expansion" found in the following company S-1 filing, page 76. This estimate is backed up by our cooling and turbine based power production calculations. The cooling calculations suggest there is enough infrastructure to support ~850MW of IT Power. Similarly the energy production calculations support ~900MW of available IT Power. This gives us confidence that the proposed expansion was achieved in time. The roof for building 3 is halfway complete.

No major changes to the data center since February. Solar panels have been placed next to the facility.

Building 3 and 4 are operational.

Based on satellite imagery, Building 1 has completed construction, with adjacent land cleared for what we're assuming will have power substations/generators. We can assume Building 1 is not operational from all the yard work directly surrounding it, and the lack of a parking lot. Building 2 (The one not leased to CoreWeave) is still in land clearing phase.

Buildings 6 and 7 roof completed. Building 8 roof nearly completed. Building 9 roof half way up. No new operational buildings.

Building 1 and 2 are operational.

Buildings 17-18 fully roofed but still having surrounding generators/cooling under construction. Cleared land for buildings 19-32 is still bare, with no building foundations visible yet. Based on satellite imagery.

We estimate Building 2 becomes operational due to being 120 days after final phases of construction, 9 months since roof and cooling were done, and similar Meta data centers construction timelines.

We assume that Anthropic has started using Colossus 1 now, since the announcement said they would get access to 300 MW "within the month" of May.

Building 1 and 2 are operational. The 2nd phase of an offsetting solar array goes online on May 31, 2026. Idaho Public Utilities Comission's approval for this start date notes that "[Meta]’s load is expected to increase so much that it will suffer a capacity deficit in June 2026 if served only by Pleasant Valley Solar 1.1,” A redacted table in the staff comments document suggests the data center's load will continue to increase through August, when it presumably reaches the maximum capacity of both buildings.

Building 1 is operational. On February 26, Terawulf stated that CB3 was expected to be energized by mid-May 2026. A drone video commissioned from RAAD shows several cooling units operating on May 8. It's therefore likely that the building was fully operational around this date.

Building 2 looks almost complete, but still appears to have three cooling towers missing. We therefore expect another 3 months until full operation.

Buildings 3 and 4 are estimated to be operational. On April 22nd, Oracle posted 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.

Building 3 is operational, based off of colored motion artifacts from cooling towers.

Based on satellite imagery, Building 3 has cleared its land and is beginning construction. Building 2 is operational judging from the colored motion artifacts on the cooling tower fans.

Building 7-11 (Meta tents) look structurally complete but not operational, given there is still construction activity, including at the adjacent Socrates South power plant. Northern tents (Buildings 16-27) are all roofed except for 21 and 27.

Building 5 has all cooling towers installed, and all other components look complete, but there is still light work around the building. Based on that, we estimate 3 more months until operational.

Satellite imagery shows Building 1 in the northern campus still appears structurally finished, with no visible change from the prior two months, but we're still not counting it operational due to visible construction work around the perimeter. Buildings 2-3 still have nearby generators/cooling equipment being installed, and Building 4 is only roughly 80% roofed. Eastern campus Buildings 5-9 remain operational. Middle campus Buildings 10, 12, 13, and 14 remain operational; Building 11 is still installing backup generators and is not counted.

Building 4 still has some equipment strewn around the perimeter, so we think it is still going through commissioning. Two new buildings at the campus have shells underway, but we don't know if Microsoft is the tenant for those.

The main shell of Building 2 looks almost completed. In Area 2 (northwest of Buildings 1-2), the grading for the original design has been replaced with grading for the new 9-building design, making way for Buildings 3-11. Work continues on the northern substation in Area 2.

Building 2 is close to being operational. There is only construction left on the backup generators, which are almost complete. Some equipment is also strewn around the building, especially near the air-cooled chillers. Preparation seems to have begun for Building 3 at the site.

Building 3 appears almost complete, with only minimal construction work and equipment remaining. The cooling towers are spaced apart in an unusual way, but there's no obvious sign that more will be installed before operation. Buildings 4 and 5 haven't started construction yet, the cleared land is still empty.

Buildings 1-4 are operational, based on the buildings shells and backup generators and most of the landscaping looking complete. Building 5 roof is complete but still lacks cooling equipment.

Building 5 is estimated to be operational, based on the previous entry.

Building 2 and 3 are operational, based on the previous entry.

Building 1 operational. This is based on the fact that is no more visible equipment or construction around the building, and based on previous imagery and when construction started on the last pieces of equipment (fans). Building 2's roof is complete, with generator construction more than halfway complete and cooling construction beginning. Electrical equipment on the side of Building 2 is also around halfway complete.

Similar to April, Buildings 1-3 shells look complete. Buildings 4-6 are still far along, and the eastern Building 7 foundation is still underway.

Anthropic announces their agreement with SpaceX to use all of the compute capacity at Colossus 1. They state that this corresponds to more than 300 MW (presumably IT power) and over 220,000 GPUs. This is slightly different to previous reports adding up to 230,000 GPUs, but still roughly consistent with our estimates.

Core Scientific said Marble was fully handed over to CoreWeave with about 65 MW of billable customer power online.

Buildings 1 and 2 visibly complete and operational. Building 3 appears complete and may be commissioning, but it's likely not operational yet given the immediate surrounding construction work. Several additional building shells and pads are still in construction, but none are assumed operational due to all the construction work visible. This is based on satellite imagery from this date.

Building 4 shell mostly complete, Building 5 steel framing is underway.

Building 1 shell, electrical and cooling equipment looks complete, with minimal construction work, so we expect it to be operational within 3 months.

Satellite image shows strong evidence that Buildings 1 and 2 are operational: colored motion artifacts on many cooling fans, plus cars parked at the building entrances.

Building 1 roof finished. Satellite imagery shows construction vehicles and concrete pads with no air cooled chiller units indicating Buildings 1 and 2 cooling install continues. On the other side of each building, emergency generator install continues as well.

Building 4 operational. No more visible construction, and since only 3 fans needed to be installed since Feburary, operational date was likely soon after. Building 5 roof almost complete.

Estimated: AI building 1 should be operational. Major construction work finished by January 31, 2026, and the shell looked complete by that date. We estimate after three months the building will be operational.
