Massive datacenter buildouts continue
Data center construction accelerates dramatically, with power grid constraints becoming a real bottleneck.
What AI 2027 Predicted
The scenario describes a massive physical buildout of AI compute infrastructure — data centers at unprecedented scale, with power grid constraints becoming a genuine bottleneck for further expansion.
How We Track This
We monitor:
- Data center construction announcements and progress
- Power procurement and grid constraint reports
- GPU deployment numbers from NVIDIA and other suppliers
- Regulatory and permitting bottlenecks
Current Evidence
Stargate One in Abilene has 2 buildings operational, with 8 more under construction through Q1 2027 and 9,000 workers on-site daily. Five more Stargate sites have been announced. Some expansion plans have been scaled back (Oracle/OpenAI abandoned the 2GW expansion at Abilene), but overall buildout remains substantial. Power grid constraints are increasingly cited as a bottleneck, consistent with the scenario’s prediction.

Counterevidence & Limitations
- Some planned expansions have been scaled back or delayed (e.g., the 2GW Abilene expansion), raising questions about whether announced capacity will fully materialize
- Power grid constraints could slow buildout significantly below planned rates — some projects face multi-year waits for grid connections
- Not all announced capacity will necessarily be used for AI training vs. inference, and the mix matters for the scenario’s capability predictions
- Announced ≠ built ≠ operational: there is a significant gap between press releases and actual compute online
- If AI revenue growth disappoints, some of these capital-intensive projects may be delayed or cancelled, similar to overbuilding patterns in previous tech cycles
What Would Change Our Assessment
- Downgrade: Multiple major projects cancelled; significant pullback in construction
- Maintain: The buildout is clearly happening at massive scale
