TeraWulf’s AI Revenue Tops Bitcoin Mining For First Time In Q1 2026

For the first time since it began publicly trading, TeraWulf earned more money renting compute to AI customers than it did mining Bitcoin. The Maryland-based operator reported $21 million in high-performance computing lease revenue against just under $13 million from digital asset mining for the three months ended March 31, 2026, flipping a decade-old revenue mix that defined the public miner cohort. Total quarterly revenue came in at $34 million, roughly flat year over year, but the composition tells the real story.

That mix shift, disclosed on May 8 in TeraWulf’s Q1 2026 earnings release, lands in the middle of an industry-wide scramble. Hut 8, IREN, Core Scientific, and Riot Platforms have all signed multi-year AI hosting deals worth tens of billions in contracted revenue. TeraWulf is the first to show that pivot landing on the income statement at majority weight.

The Quarter HPC Finally Beat Bitcoin

HPC leasing contributed roughly 62% of total Q1 revenue. Mining contributed the rest. A year earlier the split was inverted, with bitcoin mining bringing in $34.4 million against essentially zero HPC contribution. The mining line collapsed 62% year over year as TeraWulf deliberately throttled hash capacity to free up power for data center buildout.

CEO Paul Prager framed the shift on the earnings call as a milestone the company has been engineering for two years. “This is the first period where HPC leasing is meaningfully reflected in our financials,” he said. CFO Patrick Fleury followed with the harder claim, telling analysts the company is moving from “volatile bitcoin mining revenue to stable, contracted HPC revenue streams” backed by investment-grade counterparties. The phrasing matters because it signals to bondholders, not just equity holders, that the cash flow profile has changed.

HPC lease revenue rose 117% quarter over quarter. That’s the operational number worth tracking. Mining revenue is no longer the lead figure on TeraWulf’s investor deck.

Inside The $427 Million Loss That Isn’t Really A Loss

Read the headline net loss and the quarter looks catastrophic. TeraWulf reported a $427.6 million loss for Q1, or $1.01 per share, against a $61.4 million loss the year before. Strip out the non-cash items and the picture inverts.

Three accounting charges drove almost the entire deficit. A $216.3 million loss on the change in fair value of warrants. A $101.4 million stock-based compensation expense. A $25.7 million impairment charge tied to retired mining gear. Together that’s $343.4 million of charges that moved no cash, according to the company’s 8-K filing detailing Q1 2026 results.

The warrant line is the awkward one. WULF shares are up roughly 650% over the trailing twelve months. Because TeraWulf’s outstanding warrants are classified as liabilities rather than equity, the company must mark them to market each quarter. When the stock rips, the warrant liability balloons, and the difference flows through the income statement as a loss. Investors who care about cash generation back it out. GAAP investors cannot.

Adjusted EBITDA tells a cleaner story. The loss narrowed slightly to $4.1 million in Q1 2026 from $4.7 million a year earlier, even as the company carried elevated buildout costs. Liquidity is also unusually deep for a company this size.

• $2.63 billion in cash and cash equivalents at quarter end
• $462.7 million in restricted cash earmarked for project debt
• $250 million revolving credit facility closed during the quarter
• $13 billion in cumulative contracted HPC revenue under signed agreements

That cash pile is what changes the analyst conversation. Most pivoting miners are selling Bitcoin to fund the swap. TeraWulf raised structured equity and debt against future lease cash flows instead, giving it room to build without dumping treasury holdings into the spot market.

Lake Mariner Becomes The Anchor, Not The Side Project

Lake Mariner sits on a former coal plant site in upstate New York with dual 345 kV transmission lines and a freshwater lake feeding cooling systems. As of March 31, the campus had 60 megawatts of critical IT capacity energized and generating revenue for Core42, the Abu Dhabi infrastructure unit of G42. That single deal is now producing the bulk of HPC lease income.

The Fluidstack expansion is the bigger swing. In August 2025 TeraWulf signed agreements covering more than 200 MW of critical IT load at Lake Mariner with the Google-backed compute platform, plus a CB-5 expansion adding another 160 MW. A separate 168 MW Texas joint venture in Abernathy followed in October. Google backstopped roughly $3.2 billion of the lease obligations and took warrants that put its pro forma equity at about 14% of TeraWulf, per TeraWulf’s October 28 partnership announcement.

Add it up and TeraWulf has roughly 592 MW of contracted critical IT load across two campuses, more than nine times the capacity currently producing revenue. The execution risk is no longer about winning customers. It’s about energizing buildings on schedule.

Why Activists Are Forcing The Same Pivot Across The Sector

The same week TeraWulf reported, Riot Platforms posted Q1 revenue of $167.2 million, including $33.2 million from a brand-new data center segment. The split is striking: bitcoin mining still produced $111.9 million of Riot’s quarter, but data center revenue is the line analysts are repricing the stock against.

Activist investor Starboard Value has made that explicit. Starboard expanded its WULF and RIOT positions through Q1 and pressed Riot to accelerate AI conversion at its 1.7 GW Texas footprint, arguing the company could generate more than $1.6 billion in annual EBITDA if it monetized power at recent benchmark rates.

Markets are signaling clearly which version of these companies they prefer. Miners with secured AI contracts now trade at 12.3x forward sales. Pure-play Bitcoin miners trade at just 5.9x.

That valuation gap, documented by independent crypto-mining analyst Jaran Mellerud in his April market note, is roughly double. It explains why every operator with surplus power and a pre-energized substation is racing to convert. The economics aren’t subtle. A megawatt dedicated to AI hosting under a 10 to 15-year fixed lease can generate three to five times the gross profit of the same megawatt running ASICs at current hashprice levels of about $36 per petahash per day.

The catch is capital intensity. Building AI-grade infrastructure costs roughly $8 million to $15 million per megawatt, against $700,000 to $1 million for bitcoin mining. The miners that can credibly raise that money on contracted cash flows survive the transition. The ones that can’t end up acquired or wound down.

The Hawesville Bet And The 2.8 GW Question

In February, TeraWulf bought the idled Hawesville aluminum smelter in Hancock County, Kentucky, from Century Aluminum for $200 million in cash plus a 6.8% minority equity stake in the development entity Raylan Data Holdings. The smelter shut in 2022 because power costs broke its economics. Its 480 MW of grid-connected capacity, dual high-voltage transmission, and on-site substation now anchor what TeraWulf says will be a $3 billion to $4 billion campus targeting Phase 1 operations in late 2027.

Fluor signed on for preconstruction. The site adds roughly 250 buildable acres on a brownfield that needs cleanup but skips the 18 to 36-month interconnect queue that kills greenfield data center projects. After folding in Hawesville, Lake Hawkeye in Lansing, and Chesapeake Data in Maryland, TeraWulf claims a 2.8 GW infrastructure portfolio across five sites.

The Kentucky local response has been mixed. Lane Boldman, executive director of the Kentucky Conservation Committee, told the Kentucky Lantern that data centers won’t revitalize industrial communities the way the Department of Energy intended when it awarded Century a $500 million green-smelter grant. Hawesville lost more than 600 manufacturing jobs when the smelter idled. The TeraWulf campus will employ roughly 100 permanent skilled workers once running, plus several hundred construction roles during phased buildout. The trade-off, jobs for property tax revenue and rural broadband investment, will define how rural America views the AI buildout for the rest of this decade.

Power Constraints Are The New Hashrate

For a decade, the metric that defined a public miner’s competitive position was exahash per second on the network. The new equivalent metric is megawatts of pre-energized, customer-ready critical IT load. Three operational variables now determine whether a miner-turned-AI-host hits its contracted delivery dates.

1. Transformer and switchgear lead times. Utility-side equipment is on 18 to 30-month backorder for high-voltage classes, the single biggest schedule risk on every active conversion project.
2. Liquid cooling readiness. Modern AI training racks pull 100 kW or more, well beyond what air-cooled mining halls were designed for. Retrofit costs run into millions per building.
3. Counterparty credit quality. Lenders are pricing project debt off the tenant. A Google backstop or Microsoft direct lease prices roughly 200 basis points tighter than an unrated AI startup tenant.

TeraWulf scores well on all three. The Google warrant structure effectively credit-enhances the Fluidstack lease, the Lake Mariner buildings are being delivered as liquid-cooled from day one, and the company secured switchgear orders against its 2026 buildings before the broader sector rush. That’s why WULF gained roughly 50% in April ahead of the print, and why the immediate post-earnings fade reflected GAAP optics rather than operational concerns.

Frequently Asked Questions

Is TeraWulf still mining Bitcoin at all?

Yes, but at deliberately reduced scale. Q1 2026 mining revenue came in just under $13 million, down 62% year over year, as the company redirected megawatts toward HPC tenants. Management has not announced a full mining exit. Hash capacity remains a transitional cash source while AI buildings energize. Investors should expect mining revenue to keep declining as a share of total through 2026 and 2027.

Why did TeraWulf report a $427 million loss if HPC revenue is growing?

Most of that loss is non-cash accounting. A $216.3 million charge came from marking warrant liabilities to market because the stock surged. A further $101.4 million was stock-based compensation, and $25.7 million was retired mining gear written down. Strip those out and Adjusted EBITDA was negative $4.1 million, slightly better than a year earlier. Cash on hand actually rose during the quarter.

What does Google’s stake in TeraWulf actually mean?

Google holds warrants that, if fully exercised, would give it roughly 14% of TeraWulf’s pro forma equity. It also backstops about $3.2 billion of Fluidstack’s lease obligations to TeraWulf. Google is not a TeraWulf tenant directly. It is the credit anchor making the Fluidstack contracts financeable, and the warrants compensate Google for that risk. Functionally, Google has skin in the game on every Fluidstack megawatt that energizes.

When will TeraWulf’s full HPC pipeline be online and generating revenue?

The 60 MW already running for Core42 will be joined by CB-3 in mid-2026 and CB-4 plus CB-5 by the end of 2026, adding roughly 364 MW at Lake Mariner. The 168 MW Abernathy joint venture in Texas targets Q4 2026 delivery. Hawesville in Kentucky is the longer build, with Phase 1 not expected until late 2027. Tracking quarterly energization disclosures is the cleanest way to monitor execution.

The pivot question for the rest of 2026 is no longer whether AI infrastructure will eclipse Bitcoin mining as the public miners’ primary business. TeraWulf has answered that. The question is which operators can actually deliver megawatts on contracted schedules, and which ones run out of cash, transformers, or counterparty patience first. By Q4 earnings season, that ranking will look very different from today’s market caps.
