The record, newest first

  1. Citing the Financial Times, Baxtel reports that the CoreWeave deal fell apart, that Poolside had trouble raising money, and that it was seeking other cloud partners. (Baxtel (summarizing the Financial Times), April 4, 2026)

  2. The Wall Street Journal reports the first 250 MW was due by the end of 2026, powered by an existing on-site gas plant and Permian Basin gas. (El Paso Inc. (from The Wall Street Journal), Oct. 19, 2025)

  3. Poolside announces a 2 GW behind-the-meter campus on 568 acres of Longfellow Ranch in Pecos County, built in eight 250 MW phases, with CoreWeave as first-phase anchor tenant. (Poolside, Oct. 15, 2025)

Conflicts and open questions

  • The original reporting on the CoreWeave exit is from the Financial Times; we cite a summary that credits it.
  • Coordinates are for Fort Stockton, the county seat; no site address has been published.
  • Not the same as the Amazon Pecos County campus already tracked.
