TeraWulf Considers $3.5B Debt Funding for Anthropic-Linked DC: Report

US-listed Bitcoin miner and hosting operator TeraWulf is reportedly exploring a major debt financing package aimed at expanding its Justified Data campus in Kentucky, a site tied to long-term AI compute demand through a lease with Anthropic.

According to a Thursday Bloomberg report, TeraWulf chief financial officer Patrick Fleury said the company is expected to seek $3.5 billion in debt financing, with investment bank Morgan Stanley leading the effort. The financing is described as potentially including leveraged loans and high-yield bonds—TeraWulf’s first move into the leveraged loan market.

Key takeaways

• TeraWulf is reportedly considering a $3.5 billion debt raise to expand its Justified Data campus in Hawesville, Kentucky.
• The Kentucky facility is leased by AI company Anthropic under a long-term agreement tied to AI compute workloads.
• Bloomberg reports the financing may involve leveraged loans and high-yield bonds, marking a new debt-market path for TeraWulf.
• TeraWulf says the Anthropic lease is expected to contribute about $19 billion in contracted revenue over the initial lease term.
• Investor scrutiny around insider trading activity and the economics of the AI data center model continues alongside the expansion plans.

Debt plans for Justified Data expansion

The focus of the reported financing push is TeraWulf’s Justified Data campus in Hawesville, Kentucky, developed to support large-scale AI computing. The company has previously outlined that initial operations are expected to begin in the second half of 2027, with full buildout targeted for early 2028.

While the specific debt instrument mix remains under discussion per the Bloomberg report, Fleury’s comments suggest TeraWulf is looking at capital structures beyond its earlier fundraising. Bloomberg added that Morgan Stanley would lead the process and that the deal is expected to be launched this year.

For investors, the choice of financing matters as much as the expansion itself. Leveraged loans and high-yield bonds often carry different risk profiles and terms than earlier senior-note style offerings, and the move could change how markets assess TeraWulf’s leverage and repayment expectations over the next several years.

Anthropic lease underpins the cash-flow narrative

Justified Data is not being built on speculation alone. TeraWulf has linked the project to Anthropic’s long-term tenancy, describing the arrangement as part of how AI computing demand is translating into new funding opportunities for data center operators.

Cointelegraph previously reported that TeraWulf signed a 20-year lease agreement with Anthropic for the Kentucky facility. In TeraWulf’s materials, the company has also projected that the project would generate approximately $19 billion in contracted revenue over the initial lease term with Anthropic.

Those contracted revenues are central to the rationale for raising large-scale financing tied to buildout. They are also likely to be used by arrangers and potential lenders to model future debt service capacity as the campus ramps from construction into operations.

How the financing fits TeraWulf’s recent capital activity

Bloomberg’s reported $3.5 billion debt seek follows earlier, sizable fundraising efforts by TeraWulf. The company previously raised $1.3 billion in December 2025 and $3.2 billion in October 2025 through debt offerings, according to SEC disclosures and a prior press release.

For example, TeraWulf’s investor materials include an SEC filing documenting the December 2025 raise (here). For the October 2025 issuance, TeraWulf’s announcement on GlobeNewswire provides additional context (here).

Cointelegraph reported it reached out to TeraWulf and Morgan Stanley for comment on the latest financing report, but had not received a response by publication time.

Still, the headline development is a qualitative shift: if the deal proceeds as described, it would be TeraWulf’s first entry into the leveraged loan market. That change could affect both lender demand and how rating agencies and investors view the firm’s capital structure as the Justified Data buildout progresses.

Expansion continues amid scrutiny of growth economics

Even as funding discussions intensify, TeraWulf has faced questions from investors about insider stock sales, shareholder alignment, and the broader logic of its growth model—particularly as AI-related momentum lifts data center-focused narratives in the wider market.

On Thursday, Blocksbridge Consulting highlighted TeraWulf as an example in a broader discussion of investor scrutiny around insider transactions at Bitcoin mining companies benefiting from AI tailwinds. Earlier coverage from Cointelegraph has also framed this as part of growing concern about transparency and alignment in the sector (here).

Beyond governance questions, TeraWulf’s AI data center economics have also been debated. In a Tuesday podcast appearance with McNallie Money, Fleury pushed back against a short-seller’s model that estimated higher maintenance costs for TeraWulf’s data centers. Fleury’s argument, as summarized in the podcast discussion, emphasized that TeraWulf’s role is to supply power and facility infrastructure, while customers handle computing equipment and technology upgrades.

Fleury also cited the long-term lease structure as a factor that limits recurring upgrades and reconfiguration costs that are more typical in data center operations. That is a key point for investors: the more predictable the cost base, the easier it can be to underwrite heavy capital spending financed through debt.

As the company looks toward initial operations in 2027 and full buildout in early 2028, the market will likely keep testing whether those economics hold up against real-world maintenance and equipment lifecycle requirements.

What to watch next

Readers should watch for confirmation of the debt terms and structure described by Bloomberg—especially whether lenders and bond buyers accept leveraged exposure at scale—and for any updated commentary from TeraWulf on how the Anthropic lease cash flows translate into debt service as Justified Data moves from construction into production.
