TeraWulf reported a 20.3% year-over-year revenue increase for the fiscal year ended December 31, 2025, reaching $168.5 million as the company aggressively transitions from Bitcoin mining to high-performance computing (HPC).
Despite the revenue growth, the Nasdaq-listed firm recorded a significant net loss of $661.4 million for the year, compared to a $72.4 million loss in 2024. This widening deficit reflects heavy investments in AI-ready data centres and rising operational costs.
The announced results highlight a fundamental inflection point for TeraWulf, emphasizing the company’s shift toward monetizing its extensive energy infrastructure through long-term contracts for AI hosting. The company’s strategic shift yielded $16.9 million in HPC lease revenue during its first partial year of operations, with $9.7 million of that generated in the fourth quarter alone.
TeraWulf has already secured 522 megawatts (MW) of critical IT load under long-term agreements, representing an estimated $12.8 billion in contracted revenue. Key to this expansion is the Lake Mariner facility in New York, which saw its capacity optimized from 162 MW to 168 MW per building without increasing construction budgets.
A major catalyst for TeraWulf’s transformation has been its deepening relationship with Google. The technology giant increased its equity stake in TeraWulf to 14% and provided a $3.2 billion backstop to support the buildout of AI infrastructure at Lake Mariner. Additionally, TeraWulf entered a 25-year joint venture with Fluidstack to develop the Abernathy HPC Campus in Texas, a move projected to generate approximately $9.5 billion in revenue over the lease term.
To fund these massive capital requirements, the company raised more than $6.5 billion in committed capital throughout 2025. This includes $3.2 billion in senior secured notes and over $1 billion in zero-coupon convertible notes. Unlike “pure-play” miners that prioritize $BTC accumulation, TeraWulf has liquidated much of its Bitcoin holdings to finance the expensive GPUs and liquid-cooling systems required for high-density AI workloads.
TeraWulf’s pivot aligns with a broader industry trend where miners are repurposing energy-advantaged sites to counter the squeezed margins following the 2024 halving. As reported by DeFi Planet, the European Securities and Markets Authority (ESMA) and other global regulators are increasingly scrutinizing the digital finance space, though TeraWulf’s focus on physical infrastructure and ESG-friendly zero-carbon energy positions it to navigate tightening environmental reporting requirements.
