Oracle and OpenAI's Abilene expansion saga detailed: 600MW expansion gets scrapped, as larger 4.5GW agreement remains on track

Oracle and OpenAI have decided to scrap plans for a 600MW expansion at their Stargate campus in Abilene, Texas, due to financing issues and winter weather disruptions. Despite reports of cancellation, Oracle refuted these claims, stating that their existing 1.2-gigawatt build is still operational. OpenAI chose to redirect capacity to other locations instead of expanding further at Abilene. Nvidia's upcoming Vera Rubin architecture, set to be available in 2026, played a role in OpenAI's decision as it offers significant cost and performance improvements over the current Blackwell racks. The broader 4.5GW agreement between Oracle and OpenAI, announced in 2025, remains on track with additional projects in the pipeline.
