TeraWulf shares rose 5% during the October 20, 2026, overnight session following announcements regarding upcoming data center capacity. The firm confirmed it remains on track to deliver its 168-megawatt Lake Mariner facility in Western New York during Q4 2026.
Why it matters
The company's expansion highlights the intensifying competition for large-scale power infrastructure required to support high-performance AI and computing workloads. This development underscores broader industry concerns regarding energy supply limitations for future superintelligence clusters.
The upcoming CB-4 data center provides 168 megawatts of power capacity within a 330,000-square-foot footprint. This adds to the existing capacity across the company's portfolio, which includes a separate 20-year lease agreement with Anthropic at the Justified Data Campus in Kentucky.
