Vantage TX1 is an operational AI data center hosting an estimated 39k H100-equivalent chips, scaling toward a projected 155k H100-equivalent chips — supported by 32 MW of IT power, rising to 128 MW — at a capital cost of $1.2 B, rising to $4.8 B. We estimate that it uses Nvidia B200 chips. The timeline of IT power and compute capacity is based on satellite imagery, regulatory filings, chip availability, and chip efficiency. Air-quality permits reveal a planned third building (TX13), though there are no signs of construction yet.
