Level 1 — Absolute Beginner

Anthropic is a company that makes artificial intelligence, also called AI. Anthropic just signed a big deal with another company called TeraWulf.

TeraWulf used to mine Bitcoin. Mining Bitcoin means using computers to earn digital money. Now TeraWulf will build a big computer center for Anthropic instead.

The deal will last for 20 years. It could bring in about 19 billion dollars. The new computer center will be built in Kentucky.

Many Bitcoin mining companies are now moving into AI. AI computer centers need a lot of power and space, just like Bitcoin mining did.

artificial intelligence

computer systems that can learn and perform tasks like a human mind

data center

a large building full of computers that store and process information

lease

a contract to use a building or land for a set period of time

mine (Bitcoin)

to use powerful computers to create and earn digital currency

revenue

the money a company earns from its business

campus

a group of buildings used together for one purpose

demand

how much people or companies want something

Level 2 — Elementary

Anthropic, the company behind the Claude AI assistant, has signed a 20-year lease with TeraWulf that is expected to generate about 19 billion dollars in revenue over the life of the deal. TeraWulf will build a purpose-built AI computing campus at its Justified Data site in Hawesville, Kentucky.

The new campus will provide roughly 401 megawatts of computing power once it is fully built. The first part of the site is expected to come online in the second half of 2027, with the whole project finished by early 2028.

TeraWulf originally built its business around Bitcoin mining, using large amounts of electricity to run computers that earn digital currency. In recent years, though, many Bitcoin miners have been converting their sites into AI data centers, since both activities need similar amounts of power and cooling.

The Anthropic deal alone is worth more than TeraWulf's entire market value before the announcement. To build the new campus, TeraWulf plans to invest between 3 billion and 4 billion dollars, a small fraction of the total value of the lease.

Level 3 — Intermediate

Anthropic has signed a 20-year lease with TeraWulf projected to generate approximately 19 billion dollars in contracted revenue, cementing the AI developer's push to lock in long-term computing capacity as demand for its Claude models continues to surge. Under the agreement, TeraWulf will build a purpose-built infrastructure campus at its Justified Data site in Hawesville, Kentucky, accommodating an estimated 401 megawatts of critical IT load once fully operational.

The site's initial phase is slated to come online in the second half of 2027, with full capacity reached by early 2028, a timeline reflecting the multi-year construction and power procurement required for facilities of this scale. Notably, the contracted revenue from this single lease exceeds TeraWulf's entire market capitalization prior to the announcement, a striking illustration of how AI infrastructure deals are reshaping valuations across the sector.

TeraWulf's transformation mirrors a broader industry shift: since the start of the year, Bitcoin miners have collectively sold off more than 15,000 coins from their peak holdings while signing upward of 70 billion dollars in AI computing contracts, chasing the steadier margins that long-term AI leases offer compared to the volatile economics of cryptocurrency mining. Both activities share underlying infrastructure needs, dense electrical capacity and industrial-scale cooling, making the pivot technically straightforward even as it represents a fundamental change in business model.

To fund construction, TeraWulf intends to invest between 3 billion and 4 billion dollars, representing less than a fifth of the lease's total contracted value, a capital-light structure that has made such deals attractive to infrastructure investors seeking exposure to AI's growth without taking on model-development risk directly.

contracted revenue

income guaranteed under a signed agreement over its term

procurement

the process of obtaining goods or services, often through formal agreements

market capitalization

the total value of a company based on its stock price and number of shares

volatile

likely to change quickly and unpredictably

margin

the difference between the cost of something and the price it is sold for

infrastructure

the basic physical systems needed for a business or economy to function

capital-light

requiring relatively little upfront investment compared to potential returns

exposure

the degree to which an investor is affected by a particular market or risk

Level 4 — Advanced

Anthropic has entered into a 20-year lease with TeraWulf projected to yield approximately 19 billion dollars in contracted revenue, a deal that both cements the AI developer's strategy of securing long-duration computing capacity against surging Claude-model demand and crystallizes how thoroughly AI infrastructure economics have come to eclipse those of the industry TeraWulf once inhabited. Under the arrangement, TeraWulf will erect a purpose-built campus at its Justified Data site in Hawesville, Kentucky, engineered to accommodate roughly 401 megawatts of critical IT load once fully commissioned, a scale of electrical provisioning that places it firmly among the largest dedicated AI facilities announced to date.

The timeline, an initial tranche online in the second half of 2027 and full capacity by early 2028, underscores the multi-year lead times now inherent to power procurement and construction at hyperscale magnitude. More striking still is the arithmetic: the lease's contracted revenue alone surpasses TeraWulf's entire market capitalization prior to the announcement, a valuation inversion that has become almost routine as AI infrastructure leases reprice formerly niche industrial operators virtually overnight.

TeraWulf's pivot is emblematic of a sector-wide reallocation. Since the year's start, Bitcoin miners have collectively liquidated upward of 15,000 coins from peak holdings while inking more than 70 billion dollars in AI computing contracts, forsaking the notoriously volatile economics of cryptocurrency mining for the comparatively predictable margins that long-duration AI leases afford. The transition is technically frictionless precisely because both enterprises rest on identical infrastructural bedrock, dense electrical capacity paired with industrial-scale cooling, even as it constitutes a wholesale reinvention of business model and investor thesis alike.

Financing the buildout, TeraWulf intends to commit between 3 billion and 4 billion dollars of its own capital, representing less than a fifth of the lease's total contracted value. This capital-light architecture, wherein a comparatively modest upfront outlay unlocks a vastly larger revenue stream, has proven especially attractive to infrastructure investors seeking leveraged exposure to AI's expansion without absorbing the model-development risk borne directly by firms like Anthropic itself.
