TeraWulf Lands $19B Anthropic Deal as AI Data Center Race Heats Up

The AI infrastructure boom just claimed another winner.

TeraWulf, once known primarily for Bitcoin mining, is doubling down on artificial intelligence after securing a 20-year lease agreement with Anthropic that is expected to generate around $19 billion in contracted revenue over its lifetime. Investors immediately took notice, sending TeraWulf shares soaring more than 16% in premarket trading.

The agreement centers on a purpose-built AI campus at TeraWulf's Justified Data site in Hawesville, Kentucky. When fully completed, the facility will provide approximately 401 megawatts of AI computing capacity, with the first phase expected to go live in the second half of 2027 and full deployment targeted for early 2028.

The deal is another sign that the AI race is no longer just about building better models—it's about controlling the infrastructure behind them. As frontier AI companies compete for scarce compute, long-term access to power, GPUs, and data centers has become one of the industry's biggest competitive advantages.

For TeraWulf, it's another milestone in its rapid transformation from a crypto mining company into an AI infrastructure provider. Alongside the Anthropic announcement, the company also revealed it is selling its majority stake in the Abernathy joint venture to a Fluidstack-led investor group, freeing up capital to expand its wholly owned AI infrastructure business.

The announcement also aligns with reports from last month that Anthropic was actively pursuing long-term U.S. data center leases to secure the computing capacity needed for future AI models.

Why it matters

The AI industry's biggest bottleneck is no longer chips alone—it's power and data centers. Companies that control large-scale AI infrastructure are becoming just as strategically valuable as those building foundation models.

The upside

• Anthropic locks in long-term AI compute capacity.
• TeraWulf secures predictable, recurring revenue over two decades.
• The deal reinforces the growing trend of crypto infrastructure companies pivoting into AI.

The downside

Building hyperscale AI campuses requires enormous capital, reliable electricity, and years of construction. Any delays in power delivery, permitting, or deployment could push back revenue timelines, while demand must remain strong enough to justify these multibillion-dollar investments.

The takeaway

The AI gold rush has entered its infrastructure era. Winning won't just depend on who builds the smartest model—it will also depend on who owns the servers, electricity, and data centers that make those models possible. TeraWulf's $19 billion agreement with Anthropic is one of the clearest signals yet that AI infrastructure is becoming one of the world's most valuable businesses.
