TLDR: Bitcoin miner TeraWulf reported a significant widening of its first-half losses, including an $18.4 million net loss in the second quarter of 2025, despite an increase in revenue. This financial downturn is largely attributed to escalating operational costs, substantial stock-based compensation, and a sharp rise in Bitcoin mining expenses following the recent halving event. Concurrently, the company is making a strategic pivot, heavily investing in transforming its Lake Mariner facility into a high-performance computing (HPC) hub for artificial intelligence clients. A key part of this strategy is a 10-year, 72.5-megawatt contract with Core42, the U.S. arm of Abu Dhabi’s G42, with revenue generation from this AI hosting venture anticipated to commence in the third quarter of 2025.
TeraWulf Inc. (Nasdaq: WULF), a prominent Bitcoin mining company, has announced a substantial increase in its financial losses for the first half of 2025, even as its revenue saw an uptick. The company reported a net loss of $18.4 million for the second quarter, pushing its first-half deficit to $79.8 million, a figure nearly four times higher than the loss recorded in the same period last year.
Despite the deepening losses, TeraWulf’s revenue for Q2 2025 rose by 34% year-over-year, reaching $47.6 million. However, this growth was overshadowed by several factors weighing on the company’s bottom line, including higher operational costs, significant stock-based compensation, and increased depreciation linked to new infrastructure investments. A major contributing factor to the financial strain has been the shift in power economics post-April’s Bitcoin halving, which saw TeraWulf’s average cost to mine a single Bitcoin surge to $45,555, a stark increase from $22,954 a year earlier. The company self-mined 485 BTC in the quarter, a decrease from 699 BTC in the corresponding period last year. Despite the overall loss, the company’s earnings per share loss of $0.05 was slightly better than analysts’ predictions of a $0.06 loss.
In a strategic move to diversify its revenue streams and mitigate the volatility inherent in cryptocurrency markets, TeraWulf is aggressively pursuing a transition into the artificial intelligence (AI) hosting sector. The company is investing heavily in converting its flagship Lake Mariner facility in Barker, New York, into a high-performance computing (HPC) hub designed to serve AI clients. This initiative is underpinned by a significant 10-year agreement with Core42, the U.S. division of Abu Dhabi-based technology group G42, to deliver 72.5 megawatts of data-center capacity in phases through early 2026.
Paul Prager, Chief Executive Officer of TeraWulf, stated, “We made remarkable progress toward delivering Core42’s contracted 72.5 megawatts of HPC capacity.” He also indicated that discussions are ongoing to further expand AI hosting capabilities at the Lake Mariner campus. Patrick Fleury, Chief Financial Officer, highlighted the importance of this pivot, calling the Core42 deal “a key inflection point,” with revenue from the HPC hosting expected to begin flowing in the third quarter of 2025.

The Lake Mariner site, which occupies the grounds of a former coal-fired power station, is connected to a predominantly zero-carbon grid and boasts the potential to scale its capacity to as much as 750 MW. To fund this ambitious AI expansion, TeraWulf recently divested its 25% stake in the Nautilus nuclear-powered facility in Pennsylvania, securing $85 million in cash and equipment. The company ended the quarter with $90 million in cash and Bitcoin, alongside $500 million in convertible notes due in 2030, providing a financial cushion for its ongoing transition. TeraWulf, founded in 2021 by energy industry veterans Paul Prager and Nazar Khan, continues to position itself as a leader in sustainable digital infrastructure, focusing on both Bitcoin mining and the burgeoning AI hosting market.
