TeraWulf’s Big U‑Turn: From Bitcoin Mining to AI Data Centers

Pivoting from miners to mega-servers

TeraWulf has been quietly swapping out its black‑and‑green bitcoin miner vibe for racks full of high‑performance computing gear. In Q2 the company’s Bitcoin mining income plunged—down about 73% year over year—while leasing space and power for AI and other heavy compute workloads surged. That high‑performance computing (HPC) leasing now makes up roughly 71% of the company’s revenue, which pretty much means mining is now the side hustle.

The shift isn’t just a branding tweak. Portions of the Lake Mariner site in New York that used to hum with miners are being repurposed for contracted HPC customers. Long‑term data center leases are becoming the business TeraWulf counts on to pay the bills instead of coin rewards from miners.

Numbers, pain and the Anthropic gamble

Here’s the wallet‑watch: digital asset (mining) revenue fell to about $12.8 million from $47.6 million a year earlier, while HPC leasing brought in roughly $31.9 million—so total quarterly revenue landed around $44.8 million. That new leasing revenue softened the blow from the mining collapse but still left overall sales slightly lower versus last year.

The pivot hasn’t been cheap. The company reported a massive net loss in the quarter—about $940.8 million—which was heavily influenced by a $755.7 million noncash accounting hit related to warrant liabilities. Year‑to‑date losses are hovering near $1.4 billion. Translation: lots of buildout and balance‑sheet wrangling as they retool the business.

On the capacity front, Lake Mariner was producing revenue from roughly 81 megawatts (MW) of critical IT capacity at the end of June, and an early‑July delivery bumped that to about 102 MW. Another 336 MW is still under construction, with the first of that coming online and starting to generate rent in the second half of 2026. A big chunk of progress also triggered a $600 million credit backing related to one tenant’s lease obligations.

Looking farther ahead, the company signed a long‑term 20‑year deal to provide roughly 401 MW at a campus in Kentucky to a major AI customer. That contract carries many billions of dollars in potential contracted revenue and is only expected to start delivering initial capacity in the second half of 2027, with full delivery into early 2028. If extension options are exercised, the total revenue tied to that deal could grow substantially.

Despite the heavy costs of the buildout, management says it still wants to line up another 250–500 MW of critical IT capacity per year, but will be choosy: projects need secured power, confirmed customer demand, scalable infrastructure and sensible risk‑reward economics.

Bottom line: TeraWulf is no longer just a Bitcoin miner. It’s trying to become a landlord for the AI era—and that transformation is expensive, a little messy, and potentially lucrative if those long‑term leases actually pay off. Stay tuned for more construction updates and the inevitable spreadsheet drama.
