Terawulf and IREN Bet Big on AI as Bitcoin Mining Shrinks

The Big Shift from Bitcoin Mining to Artificial Intelligence

Traditional Bitcoin mining is becoming less profitable for major public companies. Because of this, leading mining firms are dramatically changing their core business strategy.

Firms like Terawulf and IREN are redirecting their massive power infrastructure away from crypto mining. Instead, they are leasing out high-performance computing power to artificial intelligence (AI) tech companies.

Think of it like converting an old industrial factory into a modern tech hub. The electrical grid and physical building are already in place, but the operations inside are completely new.

Terawulf Reports Strong Q3 Revenue Driven by AI Leasing

In the third quarter of 2026, U.S. digital infrastructure provider Terawulf generated $76.2 million in total revenue. This total represented a significant year-over-year increase.

The primary driver of this growth was high-performance computing (HPC) data center leases. HPC revenue climbed to $63 million, accounting for roughly 83% of total quarterly sales.

At the same time, legacy Bitcoin mining revenue continued to shrink as a overall percentage of income. This trend highlights Terawulf's fast shift toward hosting AI workloads.

Operating Losses Expand Due to Rapid Infrastructure Costs

Despite top-line revenue growth, Terawulf experienced significant pressure on operating profitability. Its operating loss widened to $88.2 million in Q3 2026, up from $24.7 million in Q3 2025.

This widening loss was driven by rising selling, general, and administrative expenses. The company hired technical personnel and expanded operations to build out its multi-gigawatt pipeline.

Interest expenses also increased significantly due to additional debt and convertible notes used to finance capital projects. Total expenses doubled to $164.5 million from $75.3 million a year earlier.

Building Major AI Data Center Facilities

Terawulf is making large investments to grow its data center infrastructure across multiple key locations:

• Lake Mariner Facility: Had 102 megawatts (MW) of operational capacity on Sept. 30, with 336 MW more under construction at $8 million to $10 million per MW.
• Justified Campus: Signed a 20-year lease with Anthropic for roughly $19 billion in contracted revenue, backed by a Google credit guarantee.
• Muskie Campus: Expanded power capacity at this Kentucky site to 1 gigawatt (GW) for long-term growth.

To finance these capital requirements, Terawulf ended the quarter with $2.4 billion in cash, cash equivalents, and restricted cash.

The firm also sold its 50.1% stake in the Abernathy Joint Venture for $250 million upfront cash. Additionally, it expanded its revolving credit line commitments to $400 million.

IREN Reports Sharp Fall in Mining Output Amid Strategic Transition

Nasdaq-listed miner IREN is undergoing a similar business pivot toward AI cloud operations.

According to SEC filings for the quarter ended Sept. 30, 2026, IREN earned $28 million in Bitcoin mining revenue. That was down 58% from $67 million in Q2 and down 88% from $233 million year-over-year.

Key Operational Metrics Show Changing Priorities

IREN's underlying operational numbers demonstrate how quickly its core focus is shifting:

• Bitcoin Production: Fell to 402 BTCBTC+0.20% during the quarter, down from 2,039 BTC in the previous year.
• Average Hashrate: Decreased to 8.8 exahash per second (EH/s) from 45.3 EH/s year-over-year.
• Bitcoin Treasury: Held zero Bitcoin at the end of September, reflecting its strategy of selling mined coins daily.

IREN plans to complete most of its transition to AI cloud operations by Dec. 31, 2026. Only minor mining activity is expected to continue into 2027.

AI Cloud Revenue Takes Over Main Financial Line

This operational pivot has substantially reshaped IREN's overall financial breakdown.

Total quarterly revenue grew 66% sequentially to $228 million. That growth was propelled by $200 million in AI cloud revenue, which jumped 182% from the prior quarter.

The company narrowed its quarterly net loss to $263 million from $684 million. Adjusted EBITDA rose to $66 million, up from $19 million in the previous period.

IREN reported total assets of $20.6 billion, including $6 billion in data center infrastructure. The firm holds agreements with enterprise clients including Nvidia, Microsoft, and 13 other major customers.

Market Volatility and Institutional Analyst Expectations

Pivoting to AI cloud infrastructure does not fully protect companies from market price swings.

On Nov. 5, 2026, IREN shares dropped 17% to close at $18.03 amid a broader sell-off across tech and AI equities.

Despite this drop, some market analysts maintain a $55 target price for IREN stock. This projection assumes IREN successfully completes its scheduled data center upgrades and maintains enterprise customer contracts.

However, if AI cloud demand slows down or project construction encounters unexpected delays, stock performance could decline further instead.

Why Energy Access Drives the Crypto-to-AI Shift

Why are Bitcoin miners uniquely positioned to enter the AI sector? The answer comes down to electrical power availability.

Both Bitcoin mining and AI model training require massive electrical grids and specialized cooling systems. Secured power capacity is currently one of the hardest resources to obtain in technology.

Miners hold valuable power infrastructure and high-voltage grid connections. Reallocating those resources to AI leasing offers stable, long-term corporate revenues.

While this transition offers predictable lease structures, it demands heavy upfront capital expenditures and ongoing debt management.
