OpenAI Stargate Milam

Burlington, Texas, United States

OpenAI Stargate Milam is an AI data center under construction in Burlington, TX, USA, with AI chips owned by Softbank and used by OpenAI. No IT power is online yet; it is projected to host an estimated 2,496k H100-equivalent chips — supported by 857 MW — at a capital cost of $32.5 B. The timeline of IT power and compute capacity is based on satellite imagery, company disclosures, regulatory filings, and chip efficiency.

Land clearing begins for the site

Small sections of building foundation construction begins, and land clearing appears to be mostly finished

Steel framing and roofing is underway for Building 1.

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.
