Miner earnings week is producing one chart in three company liveries. TeraWulf reported second-quarter revenue of $44.8 million, of which $31.9 million — roughly 71% — came from HPC lease revenue rather than bitcoin mining, per the company’s release and Blockspace’s breakdown. Its cryptocurrency revenue collapsed to $12.8 million from $47.6 million a year earlier — a 73% decline. Total revenue was down just 6%. Read those two sentences together: the mining business fell off a cliff, and the company’s top line barely noticed, because the AI-compute leases filled the hole almost dollar for dollar. As of this week, calling TeraWulf a bitcoin miner is a legacy habit, not a description.
Galaxy Digital told the same story through a different line item. Its second-quarter net loss came in at $85.3 million — narrowed 61% from the $216.3 million loss in Q1 — on adjusted EPS of −$0.09, per Cryptopolitan and Blockspace. The quarter’s real headline was the financing: Galaxy Helios Data Centers II completed a $3.507 billion issue of 9.875% senior secured notes to fund Helios Phase II and debt-service reserves, with Phase I now online. That coupon is a market price for the sector’s entire strategy: lenders will fund miner-to-AI conversions at scale, but at nearly 10% — roughly triple what hyperscalers pay for capital. The AI pivot is fundable. It is not cheap.
Three prints, one flip
| Company (Q2 2026) | Headline | The pivot number |
|---|---|---|
| TeraWulf (WULF) | $44.8M revenue (−6% YoY) | 71% of revenue from HPC leases; crypto revenue −73% YoY; ~$3.0B cash; 102 MW online at Lake Mariner, 336 MW contracted to come |
| Galaxy (GLXY) | −$85.3M net (61% narrower than Q1) | $3.507B notes at 9.875% for Helios Phase II; Phase I online |
| MARA | −$611M net on $174.9M revenue | Holdings deployed (−29% to 35,577 BTC); Exaion closed, Long Ridge agreed; FY26 guide $810M |
Set this table against the benchmarks already on the board this season — Hut 8’s $9.8 billion AI hosting agreement disclosed in July, and Microsoft, Meta, Apple and Amazon all raising AI capex guidance in the same two-week window — and the sector’s repricing logic becomes visible. The market is no longer valuing these companies on exahash or even on bitcoin holdings; it is valuing megawatts, grid interconnects and signed compute leases. TeraWulf’s 102 MW of revenue-generating IT capacity that came online at Lake Mariner in early July, with another 336 MW contracted, is the kind of line that used to appear in data-center REIT filings, not miner earnings. The equity market has voted on the model; the bond market just set its price at 9.875%.
What it means for bitcoin itself
For the bitcoin network, this week’s prints carry two concrete implications. First, hashrate competition for power is now real: every megawatt TeraWulf leases to AI tenants is a megawatt not hashing, and with the smallest difficulty cut of 2026 (−0.74%) behind us and the next retarget due around August 11, the marginal economics of hashing at $64K bitcoin keep pushing operators toward compute contracts. Second, miner treasuries are becoming funding pools: MARA’s 29% holdings reduction and Strategy’s loss-taking sale in the same fortnight mean two of the market’s most reliable structural holders are now structural suppliers — the flow the ETF complex has so far absorbed, as this morning’s companion analysis details. Riot, the one major miner yet to show its hand this season, still has not named its rescheduled earnings date; our standing marker expects one by August 13. When that print lands, the revenue-flip table above gets its fourth row — and if Riot’s HPC line is anywhere near TeraWulf’s 71%, the phrase “bitcoin miner earnings season” will officially describe a sector that no longer exists.
How much of TeraWulf’s revenue now comes from AI?
About 71% — $31.9M of its $44.8M Q2 revenue was HPC lease revenue, while bitcoin mining revenue fell 73% year over year to $12.8M.
Did Galaxy Digital have a good quarter?
Mixed: still an $85.3M net loss, but 61% narrower than Q1, with Helios Phase I online and a $3.5B financing completed for Phase II at a 9.875% coupon.
Why are miners pivoting to AI compute?
AI tenants pay contracted, dollar-denominated lease rates that do not halve every four years or swing with bitcoin’s price — and at ~$64K BTC with rising difficulty, many megawatts earn more hosting GPUs than ASICs.
Is this bullish or bearish for bitcoin?
Two-sided: less industrial hashpower demand and more miner selling are short-term supply headwinds, but a financially healthier miner sector reduces forced-liquidation risk in downturns. This is context, not investment advice.
What is next for the sector this month?
Riot’s rescheduled earnings date (expected by August 13), the ~August 11 difficulty retarget, and the August 12 CPI print that will move the rate backdrop every miner balance sheet leans on.
