TeraWulf Muskie AI Campus Doubles Contracted Power to 1 GW, October 2026

TeraWulf confirmed via SEC 8-K that contracted power at its Muskie AI campus in Kentucky has doubled to 1 GW, with a second phase targeting 2029 delivery, even as WULF shares fell roughly 5 percent to $14.79 with no publicly reported explanation.

TeraWulf's confirmation via SEC 8-K that its Muskie AI data center campus in Kentucky now carries 1 gigawatt of contracted power capacity doubles the 482 megawatts the Kentucky Public Service Commission approved in August 2026 and represents the company's most consequential capacity milestone since committing to its AI pivot. A second phase of the build is scheduled for 2029 delivery. WULF shares fell roughly 5 percent to $14.79, with no publicly reported explanation for the decline — leaving a gap between the headline capacity number and how markets are currently pricing execution risk.

The Muskie milestone is the latest inflection point in a rapid strategic reorientation. Less than two years ago TeraWulf was primarily a Bitcoin miner operating the Lake Mariner facility in upstate New York. By mid-2026 its AI and high-performance computing revenue had formally overtaken its legacy mining business, and capital expenditure reached $1.06 billion in FY2025 — a 295.7 percent increase from $268 million in FY2024 — representing a capex-intensity ratio of 629 percent of that year's $168 million in revenue. That figure places TeraWulf second among seven neoclouds tracked by Slicast by intensity, behind Nebius, and fifth by absolute capex, where CoreWeave leads the field. The company's highest single-quarter spend reached $523 million in the quarter ending March 31, 2026. A capex-to-revenue ratio at that level signals a company still deep in construction mode, where the investment case rests almost entirely on the value of future contracted cash flows rather than current earnings.

Multiple reports have described Anthropic as the anchor tenant at Muskie, with one report characterizing the arrangement as a 20-year capacity lease; TeraWulf's chief executive was reportedly described as saying the Anthropic relationship represents only the opening phase of the company's infrastructure expansion, with further deals in the pipeline. A separate single-source report cited a $3.2 billion backstop financing commitment from Google to support the campus build. Neither the specific lease terms nor the Google commitment have been confirmed in full through company disclosure or regulatory filings, and both claims carry the uncertainty inherent in single-source reporting. What has been confirmed via 8-K is the 1 GW contracted power figure and the 2029 second-phase timeline. One analyst has pointed to a 3-gigawatt long-term capacity target from management and argued for more than 25 percent upside on that basis; Morgan Stanley highlighted TeraWulf alongside Cipher Mining and Marathon Digital as positioned to benefit from the broader miner-to-AI pivot.

The Kentucky expansion is proceeding with active state support: TeraWulf formally committed to Governor Andy Beshear's requirements for large data-center operators, and a projected 300 jobs and $536.8 million in cumulative local tax impact from a separate Hancock campus underscore the political economy behind Kentucky's receptiveness. The contrast with New York is sharp. Protesters near Cayuga Lake, activist pressure on Governor Hochul to sign the Responsible Data Center Development Act — legislation that would impose stricter zoning and environmental review on facilities like TeraWulf's — and the town of Lansing's move to draft a data-center ban directly targeting a proposed TeraWulf facility have made the company's New York footprint a live regulatory variable. A fire at the Lake Mariner data center also prompted a safety review and operational suspension, adding an execution risk layer that progress in Kentucky does not resolve.

The valuation picture is contested. After the Kentucky power approvals, at least one analyst argued WULF could be 60 percent undervalued; but near-term performance has been sensitive to factors beyond TeraWulf's own fundamentals. A rate-driven selloff in August took WULF down roughly 6 percent in a session alongside CoreWeave and Nebius, illustrating how sector sentiment oscillates with interest-rate expectations. CEO Paul Prager sold 137,500 shares for approximately $2.3 million during the strategic transition, a disclosure investors typically weigh alongside management's public growth narrative.

The 1 GW milestone is a confirmed infrastructure commitment rather than a letter of intent — a meaningful distinction in a sector where announced capacity frequently outruns delivery. Whether the investment thesis holds depends on three concrete signals worth tracking: how quickly the 2029 second phase secures offtake agreements beyond the reported Anthropic anchor; whether New York's regulatory trajectory impairs Lake Mariner or the Lansing project enough to alter the company's asset mix; and whether the $523 million single-quarter capex rate generates contracted revenue at a pace that begins to close the gap on the 629 percent intensity ratio before lenders or market conditions force a reset.
