Bitcoin gained 21.5% from the Aug. 17 shut by means of Aug. 21, but six of seven massive US-listed miners completed the identical buying and selling stretch a lot decrease. MARA Holdings rose 16.1% and got here closest to BTC, whereas Cipher Digital fell 14.8%, TeraWulf misplaced 11.2%, Hut 8 dropped 8.1%, and IREN declined 6.8%.
The shares nonetheless offered as Bitcoin proxies had separated throughout one in all Bitcoin’s strongest weeks of the yr.
QQQ fell 2.3% over these classes as long-term yields stayed risky, inserting the miners inside a weaker technology-equity market. Their company construction helps clarify this, as a number of former mining specialists now derive income, financing, or ahead valuation from long-duration data-center contracts.
The identical electrical energy, land, and grid connections can help ASIC miners or GPU clusters, and public markets worth every use by means of a special set of dangers.
mycryptopot analyzed two years of every day closes to see whether or not the August week match an extended sample. Bitcoin sensitivity has weakened throughout a lot of the group as data-center contracts gained weight, though the speed coefficients differ too broadly to deal with each AI-oriented miner as a long-bond proxy.
Energy is the second product for Bitcoin miners
A traditional miner primarily makes use of computing {hardware} to transform electrical energy into Bitcoin, so its working outcome depends upon the coin’s worth, community issue, transaction charges, fleet effectivity, and energy value.
Excessive fastened bills amplify that relationship as a result of a proportion enhance in Bitcoin can produce a bigger proportion enhance in anticipated fairness worth when income climbs sooner than the price base.
Bitcoin held on the stability sheet is one other layer of publicity, particularly when an organization funds enlargement whereas retaining most of its manufacturing. Buyers have up to now handled miner equities as amplified Bitcoin positions with company, financing, and execution threat connected.
That labored moderately effectively whereas mining equipped practically all income and administration groups allotted capital round hash fee.
AI infrastructure modified that as a result of energy has grow to be the scarce enter each industries pursue. A miner with a grid settlement can lease capability to a hyperscaler or construct a GPU cloud enterprise, exchanging risky mining earnings for a contract backed by a tenant’s credit score.
Debt and Bitcoin gross sales are financing these buildouts, including development schedules, tools procurement, and buyer focus to valuations that when depended solely on hash worth.
Firm filings place our little group of public miners pivoting to AI at a number of completely different levels of that conversion, with TeraWulf producing $31.9 million of its $44.8 million second-quarter income from high-performance-computing leases and roughly $12.8 million from digital belongings.
Hut 8 says its Beacon Level leases cowl 949 megawatts of contracted IT capability and carry $26.6 billion of base-term contract worth, topic to future supply and tenant efficiency.
IREN reported $70.5 million of AI cloud income and $66.7 million of Bitcoin mining income in its June quarter, transferring AI above mining in its present income combine. Its Aug. 27 launch additionally put working annual recurring income at $1 billion as of Aug. 26 and contracted ARR tied to 2026 capability at $4 billion, with the latter focused to grow to be operational by Dec. 31 topic to commissioning, testing, and buyer acceptance.
The quarter included a $450.4 million impairment largely tied to decommissioned mining {hardware} as websites convert to AI.
Cipher nonetheless recorded second-quarter income from Bitcoin mining, nevertheless it has contracted 700 megawatts of high-performance-computing capability throughout three websites and started delivering the primary capability at Black Pearl in August.
Riot Platforms sits nearer to the center, reporting $113.7 million of mining income, $23.2 million from knowledge facilities and $37.3 million from engineering in a $174.2 million quarter. Its 241 megawatts of contracted AI capability carry roughly $9.8 billion of company-estimated long-term income, giving buyers a contract e-book to worth alongside 11,380 Bitcoin held at June 30.
CleanSpark would have served as a mining-only management earlier within the yr, although that classification expired earlier than the August breakout. The corporate signed a 20-year, $6.6 billion data-center lease on Aug. 6 whereas its working income nonetheless got here from mining, inserting it within the newly hybrid group.
MARA now offers the closest massive mining-led comparator, even because it explores adjoining vitality and computing companies.
The cut up reveals up within the beta
mycryptopot analyzed Alpaca/IEX historic fairness closes for HUT, WULF, IREN, CIFR, RIOT, MARA, CLSK, and QQQ, along with Alpaca’s BTC/USD closes, from Aug. 22, 2024 by means of Aug. 24, 2026.
Day by day inventory returns used trade buying and selling days, and every Bitcoin return coated the interval between consecutive stock-market dates, so Monday observations included the weekend. Ten-year Treasury yields got here from the Federal Reserve’s DGS10 collection.
Shut-to-close returns from Aug. 17 by means of Aug. 21 seize the preliminary separation by pairing Bitcoin’s rally with QQQ as a broad technology-equity reference for a similar classes.
| Asset | Aug. 17 shut | Aug. 21 shut | Return |
|---|---|---|---|
| Bitcoin | $64,485.56 | $78,332.01 | 21.47% |
| MARA | $9.71 | $11.27 | 16.07% |
| RIOT | $20.08 | $19.82 | -1.29% |
| QQQ | $729.945 | $713.41 | -2.27% |
| CLSK | $12.405 | $11.98 | -3.43% |
| IREN | $44.93 | $41.88 | -6.79% |
| HUT | $88.04 | $80.88 | -8.13% |
| WULF | $17.60 | $15.63 | -11.19% |
| CIFR | $18.50 | $15.765 | -14.78% |
The longer calculation used rolling 90-trading-day correlations and univariate Bitcoin betas, with one comparability ending Aug. 22, 2025, and the present one ending Aug. 24, 2026.
A Bitcoin beta of 1.10 signifies that a 1% every day Bitcoin transfer was related to a mean 1.10% transfer in miners throughout that window, whereas correlation measures how constantly their instructions and magnitudes traveled collectively.
| Ticker | Present BTC correlation | BTC beta in Aug. 2025 | BTC beta in Aug. 2026 | Present QQQ correlation | Working profile |
| HUT | 0.18 | 1.18 | 0.53 | 0.45 | Knowledge-center-led |
| WULF | 0.22 | 0.75 | 0.52 | 0.53 | Knowledge-center-led |
| IREN | 0.29 | 0.93 | 0.93 | 0.60 | Hybrid, AI-led newest quarter |
| CIFR | 0.17 | 1.13 | 0.58 | 0.47 | Knowledge-center-led ahead profile |
| RIOT | 0.30 | 1.21 | 0.72 | 0.55 | Hybrid |
| MARA | 0.48 | 1.35 | 1.10 | 0.52 | Mining-led |
| CLSK | 0.37 | 1.47 | 0.88 | 0.52 | Newly hybrid |
Bitcoin beta declined from the comparable 2025 window for six corporations, with IREN holding close to 0.93, whereas Bitcoin correlation fell for six and edged up for WULF from an already low 0.17 to 0.22.
QQQ correlation exceeded Bitcoin correlation for all seven corporations within the present window, which means their every day returns tracked the Nasdaq proxy extra constantly than the coin they mine.
MARA retained the group’s highest Bitcoin correlation and beta, matching its heavier dependence on mining economics.
HUT, WULF, and CIFR occupy the underside half of present Bitcoin correlation as their data-center contracts carry extra weight in investor estimates, whereas MARA occupies the highest. IREN breaks the straightforward ordering as a result of its Bitcoin beta stayed regular whilst its QQQ correlation reached 0.60, permitting an working mining base and a big AI pipeline to seem in the identical return collection.
mycryptopot additionally ran a 2026 year-to-date regression that included every day Bitcoin returns, QQQ returns, and the every day transfer within the 10-year Treasury yield. The three-factor mannequin defined roughly 28% to 45% of every day variation throughout the seven miners, whereas the estimated impact of a 10-basis-point yield enhance ranged from a 0.52% decline for WULF to a 0.79% acquire for CIFR.
4 fee coefficients had been adverse, and three had been optimistic, so the pattern would not help a typical length commerce throughout the group.
Combined coefficients block a straightforward bond analogy as a result of larger yields scale back the current worth of money flows anticipated years from now and lift challenge financing prices, whereas every day fairness returns additionally take up tenant bulletins, development updates, Bitcoin holdings, energy costs, and capital raises.
Contracts clarify why the companies carry completely different exposures, whereas the information present no frequent fee commerce throughout the group.
Contracts give the miners a second threat map
TeraWulf is one of the best instance of an organization whose earnings assertion has already crossed into a brand new class. Excessive-performance-computing leases equipped about 71% of second-quarter income, and its filings describe repurposing or curbing mining tools as computing capability expands.
A Bitcoin rally can enhance the residual mining operation, whereas the fairness valuation now additionally depends upon tenant funds, development supply and the financing connected to the campus.
Cipher reveals how the stock-market identification can transfer earlier than the income combine catches up. Its June quarter nonetheless mirrored mining, although buyers can mannequin contracted computing capability and the company-estimated $793 million of common annual internet working earnings related to its base lease phrases.
The hole between present income and promised capability makes supply dates, capital value, and counterparty high quality central inputs for the share worth.
Riot and IREN carry each units of exposures extra visibly, though their present income mixes have separated. Mining provides most of Riot’s present income, whereas IREN’s June quarter put AI cloud income simply above Bitcoin mining income.
Their mining operations retain asset-price sensitivity, and signed AI agreements add one other stream of projected money flows. Every quarterly submitting can shift the load on Bitcoin manufacturing versus data-center supply, making beta an output of the enterprise combine somewhat than a everlasting firm trait.
Contract bulletins carry loads of uncertainty as a result of base-term worth represents funds anticipated throughout a few years, income and internet working earnings estimates rely upon well timed supply, and project-level debt protects a mum or dad stability sheet solely throughout the phrases of its construction.
A multiyear headline worth will help classify the corporate’s route, although it will probably’t substitute for a reduced cash-flow mannequin or accomplished capability.
The Aug. 17 breakout captured an actual separation, and the longer pattern confirms a broader sector reclassification. MARA rose alongside the coin, each firm retained a optimistic present Bitcoin beta, and mining money circulate nonetheless funds or helps a number of AI buildouts.
Bitcoin has grow to be one issue amongst a number of, with its weight lowest the place contracted computing capability has grow to be the middle of the fairness case.
“Bitcoin miners” now describe these corporations’ origin extra reliably than their vacation spot. Buyers shopping for the group by means of a mining basket can obtain publicity to Bitcoin manufacturing, hyperscaler credit score, development schedules, power-delivery threat, challenge finance and technology-equity multiples in numerous proportions.
The contracts assist clarify why the shares separated, whereas the remaining Bitcoin betas present their previous identification nonetheless travels with them.
