All buildings finished, site is fully operational. Our reasoning is that examples so far take a median of 2-2.5 years to go from land clearing to 1 GW. This suggests around 2028-01-01 here. However, due to delays being more likely than speedups and the fact that this base rate data is still unproven, the more conservative estimate is made. The current state of the site also supports this estimation.

Notes
The Stargate site in Milam County is one of a set of 5 Stargate sites that were [announced in tandem](https://openai.com/index/five-new-stargate-sites/). The date that this campus reaches full capacity is currently speculative. However, the planned capacity of the site has been stated by SB Energy, which will provide power for the site. [Regulatory filings on TDLR ](https://www.tdlr.texas.gov/TABS/Search/Project/TABS2026017746)indicate that the first building of the site will be completed October 2026.
