TeraWulf shares surged nearly 18% Monday after the company announced a 20-year lease with Anthropic expected to generate roughly $19 billion in contracted revenue. The TeraWulf Anthropic deal ranks among the largest single-customer commitments ever signed by a former bitcoin miner, and WULF stock traded at $24.95 in early action, up $3.77, as investors digested an agreement that transforms the Maryland company’s revenue picture through the mid-2040s.

The agreement, announced by TeraWulf before Monday’s opening bell and reported by CNBC, covers a purpose-built AI campus in Hawesville, Kentucky, about an hour southwest of Louisville. Anthropic, the AI company behind the Claude models, will lease approximately 401 megawatts of critical IT load at the site TeraWulf calls Justified Data.

Inside the $19 Billion TeraWulf Anthropic Deal

Start with the numbers, because they do most of the talking:

  • Term: 20 years, with approximately $19 billion in contracted revenue over the initial period
  • Capacity: roughly 401 megawatts of critical IT load at the Kentucky data center
  • Timeline: first capacity online in the second half of 2027, full ramp by early 2028
  • Credit: the AI data center lease is expected to be supported by an investment-grade credit

The campus will be developed in multiple phases rather than a single build.

TeraWulf bought the Justified Data site in February 2026 and made investors a specific promise at the time. “When we announced the Justified Data campus acquisition in February, we told investors that we expected to secure a major customer commitment by around the end of the second quarter of 2026,” said Paul Prager, TeraWulf’s chairman and chief executive. “The timing of today’s announcement reflects the completion of final documentation and customary transaction processes, and we are proud to announce this landmark partnership with Anthropic.”

Prager framed the deal as proof of concept for the entire business model. “The Anthropic lease validates our strategy and establishes a long-duration revenue stream with one of the world’s leading AI companies,” he said.

How Big Is 401 Megawatts of AI Capacity?

A 401 megawatt campus sits firmly in hyperscale territory. For comparison, TeraWulf’s Abernathy joint venture in Texas, itself a substantial project, totals 168 megawatts. Citi analysts note TeraWulf is building a framework capable of developing between 250 and 500 megawatts of new data center capacity every year, meaning Justified Data alone equals a full year of the company’s most aggressive development pace.

Averaged over the 20-year initial term, the lease implies roughly $950 million in annual contracted revenue once fully ramped. TeraWulf reported total revenue of well under $200 million in its final year as a pure bitcoin miner, which is why a single signature moved the stock double digits.

From Bitcoin Miner to AI Landlord

TeraWulf’s pivot mirrors the defining trade in digital infrastructure this cycle. The company built its business mining bitcoin with low-cost power, then redeployed that power expertise toward AI compute as demand exploded. According to Bitcoin.com News, mining stocks that made the AI transition have beaten bitcoin itself by 70% in 2026, and TeraWulf had already locked in $12.8 billion of AI contracts before the TeraWulf Anthropic deal pushed its contracted backlog far higher.

The timing contrast was hard to miss. On the same morning TeraWulf announced its Anthropic lease, bitcoin slipped as Strategy sold 3,588 BTC for $216 million. The economics of leasing power to AI labs on 20-year terms now compete directly with the volatility of mining rewards, and boards across the sector have made their choice.

Power is the moat. TeraWulf describes its edge as sourcing and monetizing high-value electricity, the scarcest input in AI infrastructure. Sites with secured grid connections and hundreds of available megawatts have become the industry’s most fought-over assets.

Why Anthropic Keeps Buying Compute

Anthropic’s appetite for capacity has become one of the market’s most reliable demand signals. The company closed a $65 billion Series H round at a $965 billion valuation in June and filed a confidential S-1 with the SEC, a story we covered in detail in our report on Anthropic’s IPO filing. It has also pushed compute partnerships in unconventional directions, including a compute deal with SpaceX that extends to space-based development.

Landing a 20-year commitment from a customer of that scale changes how lenders view TeraWulf. Long-duration leases backed by investment-grade credit can be financed against, which is how data center developers fund construction without endlessly diluting shareholders. Bitcoin.com News points to the company’s Lake Mariner financing, supported by a Google guarantee once operational, as the template.

The Abernathy Sale: $450 Million Out at a Premium

Buried in the same press release was a second transaction. TeraWulf agreed to sell its 50.1% stake in the Abernathy Joint Venture, a 168 megawatt campus in Abernathy, Texas established in 2025, to an investor group led by its partner Fluidstack. The sale monetizes roughly $450 million of invested capital at a premium.

“The sale of our ownership interest in Abernathy to a group led by Fluidstack crystallizes the value created through that investment,” Prager said, adding that the capital will be redeployed into wholly owned projects where TeraWulf keeps direct ownership, customer relationships, and operational control. The move also simplifies the company’s books by eliminating joint venture accounting.

Read together, the two deals sketch a clear strategy: sell minority positions in shared projects, concentrate capital in campuses TeraWulf controls outright, and sign the longest leases the market will bear.

What Wall Street Analysts Are Saying

Wall Street was constructive before Monday and got louder after. Fifteen analysts tracked by Stock Analysis rate WULF a Strong Buy on average, with a 12-month price target of $36.34, roughly 50% above the post-announcement price. BofA Securities initiated coverage with a Buy rating and a $34 target, arguing the shift from bitcoin mining into AI infrastructure positions the company for accelerating high-performance computing demand.

Citi acknowledged execution and funding risks but concluded that “the valuation still doesn’t reflect WULF’s multi-year growth opportunities.” The broader tape helped: the Nasdaq opened the week higher behind chip stocks, and the Dow briefly crossed 53,000 for the first time. Investors hunting the next wave of AI infrastructure names, a theme we track in our guide to the best AI stocks to buy now, have made converted miners one of 2026’s strongest trades, alongside deals like Akamai’s $1.8 billion AI cloud agreement.

The Risks Investors Should Not Ignore

A contracted number is not cash in hand. The $19 billion accrues over two decades, and not a dollar of Justified Data lease revenue arrives before the second half of 2027. Between now and then, TeraWulf must finance and execute a phased hyperscale build, hit its energization dates, and manage construction costs in a market where electrical equipment lead times remain stretched.

Concentration cuts both ways. A 20-year lease with one AI lab is a bet on that lab’s durability, and while Anthropic’s near-trillion-dollar valuation and pending IPO suggest staying power, the AI capital cycle has skeptics. CNBC reported the same day that semiconductor stocks are flashing warning signs of a possible top. If AI infrastructure spending decelerates, long-dated capacity commitments will be the first place the market looks for cracks.

Shareholders should also watch how the company funds the build. Citi flagged funding risk explicitly, and the Abernathy proceeds, while meaningful, cover only part of a 401 megawatt campus. The pace of debt raised against the Anthropic lease will reveal how much of the $19 billion headline converts into equity value.
