How CleanSpark Makes its Money: Bitcoin Mining Revenue Breakdown
A breakdown of CleanSpark (CLSK) financials. See how CleanSpark makes money from Bitcoin mining — with FY2024 revenue, mining economics, hash rate, cost structure, and business model detail.
Key Takeaways
- CleanSpark generated approximately $520 million in FY2024 revenue — up +65.1% year-over-year — driven by Bitcoin price appreciation and aggressive hash rate expansion through facility acquisitions
- Revenue is almost entirely derived from Bitcoin mining ($500M, 96%) — the company mines BTC with ASIC computers and sells the coins for U.S. dollars
- Gross margin: 36.5% — the primary costs are electricity and ASIC hardware depreciation; low power costs ($0.035–0.045/kWh) are the key profitability driver
- Net income swung from -$20M to +$50M — the profitability inflection was driven by Bitcoin’s price appreciation, not cost cutting; profitability remains highly Bitcoin-price-dependent
- Hash rate grew from ~9 EH/s to 30+ EH/s during 2024, targeting 50+ EH/s — each new exahash of capacity is a direct claim on Bitcoin block rewards proportional to global network share
- The April 2024 Bitcoin halving (reward: 6.25 → 3.125 BTC/block) was simultaneously a headwind (lower per-block revenue) and consolidation opportunity — CleanSpark acquired distressed miners’ facilities at attractive prices
- CleanSpark + MARA Holdings + Riot Platforms collectively dominate the U.S. public Bitcoin mining market — the post-halving shakeout accelerated consolidation into these larger, better-capitalized operators
- Share dilution is the primary investor risk — rapid expansion is funded by issuing new stock (ATM equity offerings), which grows the share count and dilutes existing holders’ economic claim on mined Bitcoin
How Does CleanSpark Make its Money?
CleanSpark (ticker: CLSK) is one of the largest publicly-traded Bitcoin mining companies in the United States, operating mining data centers across Georgia (primary), Mississippi, Wyoming, Tennessee, and Nevada. The company generates revenue the same way all pure-play Bitcoin miners do: deploying specialized computing hardware (ASICs) to compete in the global Bitcoin proof-of-work mining process, winning block rewards in newly minted Bitcoin, and selling those coins on the open market for U.S. dollars.
Founded in 2014 as a distributed energy software and microgrid management company, CleanSpark pivoted to Bitcoin mining in 2020 — acquiring its first mining facility in Georgia and deploying ASIC hardware. Since then, the company has executed an aggressive acquisition-and-optimize strategy: buying underperforming mining sites from distressed operators, deploying more efficient hardware, and leveraging lower-cost power agreements to improve facility economics.
By FY2024, CleanSpark had grown from a small regional miner to one of the largest U.S. operators by hash rate, generating $520 million in revenue and turning profitable for the first time. The April 2024 Bitcoin halving — which cut block rewards in half — paradoxically accelerated CleanSpark’s growth by forcing less-capitalized competitors to sell their facilities, which CleanSpark acquired at compressed valuations.
CleanSpark (CLSK) Business Model
Bitcoin Mining: The Proof-of-Work Revenue Engine
CleanSpark’s business model is a capital-intensive manufacturing operation — it “manufactures” Bitcoin by consuming electricity through specialized hardware. The core economics:
The Bitcoin Protocol: Every ~10 minutes, the Bitcoin network selects a winner from all competing miners to add the next block of transactions to the blockchain. The winner is chosen pseudo-randomly, but probability is directly proportional to hash rate contribution. The winner earns: (1) the block subsidy (3.125 BTC post-April 2024 halving), plus (2) transaction fees from all transactions in the block.
The Revenue Formula:
$$\text{Revenue} = \text{BTC Mined} \times \text{Bitcoin Price}$$
$$\text{BTC Mined} \approx \frac{\text{CleanSpark Hash Rate (EH/s)}}{\text{Global Network Hash Rate (EH/s)}} \times \text{Total BTC Issued per Day}$$
If the global Bitcoin network produces ~900 BTC per day (post-halving) and CleanSpark operates 5% of global hash rate, CleanSpark mines approximately 45 BTC per day. At $70,000/BTC, that’s ~$3.15 million per day, or ~$1.15 billion annualized. The actual revenue is lower than this illustrative example because CleanSpark’s hash rate share was less than 5% for much of 2024.
The Cost Formula:
$$\text{Cash Mining Cost} \approx \text{Power Consumed (kWh)} \times \text{Electricity Rate ($/kWh)}$$
$$\text{Total Cost of Revenue} = \text{Energy Cost} + \text{Hardware Depreciation} + \text{Facility Operating Costs}$$
CleanSpark’s ASIC fleet (primarily Bitmain S21 Pro) consumes roughly 17–20 joules per terahash. At 30 EH/s = 30,000,000 TH/s, that’s approximately 510–600 megawatts of power draw. At $0.04/kWh, that’s ~$20–24 million per day in electricity costs, or ~$7–9 billion annualized — clearly not a $520M company at those numbers, so CleanSpark operates at much lower actual power consumption per EH/s in practice (newer hardware is more efficient, and average hash rate during the year was well below the 30 EH/s year-end figure).
The Halving Cycle and Mining Economics
Bitcoin’s block reward “halves” every 210,000 blocks (~4 years), reducing the newly minted BTC issued per block by 50%. This is the fundamental supply mechanism designed into Bitcoin’s protocol:
| Halving Date | Block Reward | Bitcoin Supply Implications |
|---|---|---|
| Jan 2009 (Genesis) | 50 BTC/block | Full issuance begins |
| Nov 2012 (1st Halving) | 25 BTC/block | Annual supply growth ~25% |
| Jul 2016 (2nd Halving) | 12.5 BTC/block | Annual supply growth ~12.5% |
| May 2020 (3rd Halving) | 6.25 BTC/block | Annual supply growth ~6.25% |
| Apr 2024 (4th Halving) | 3.125 BTC/block | Annual supply growth ~3.125% |
| ~2028 (5th Halving) | 1.5625 BTC/block | Annual supply growth ~1.5% |
Each halving cuts miner revenue per unit of hash rate in half — unless Bitcoin’s price doubles to compensate. Historically, Bitcoin’s price has appreciated following halvings as reduced supply meets steady or growing demand. The halving creates a Darwinian selection event: miners with high electricity costs or old hardware become unprofitable and exit, creating acquisition opportunities for low-cost operators like CleanSpark.
The Acquisition-and-Optimize Growth Strategy
CleanSpark’s primary growth mechanism is acquiring distressed mining facilities at below-replacement-cost prices and improving their economics:
Identify underperforming facilities: Operators with high power costs, old hardware, or insufficient capital to survive at lower Bitcoin prices are forced sellers after a halving or bear market.
Acquire at compressed valuations: CleanSpark buys facilities that have land, power infrastructure, cooling systems, and existing utility connections — the most expensive and time-consuming parts to build from scratch.
Deploy next-gen ASICs: The acquired facility’s old hardware is replaced with Bitmain S21/S21 Pro ASICs that generate significantly more hash rate per watt of electricity consumed.
Renegotiate power agreements: CleanSpark’s scale and creditworthiness allow it to negotiate better long-term power purchase agreements than smaller operators can access.
Achieve full utilization: Once at capacity, the facility contributes positive operating cash flow. Mature facilities fund the next acquisition cycle.
This flywheel — where profitable mature sites fund new acquisitions — is how CleanSpark has compounded hash rate growth without taking on excessive debt.
Bitcoin Treasury Policy
CleanSpark primarily sells mined Bitcoin to fund operations and growth — maintaining a “sell to fund” approach rather than accumulating Bitcoin as a primary treasury strategy (unlike MicroStrategy, which borrows money to buy and hold Bitcoin). However, CleanSpark does hold some Bitcoin on its balance sheet. Under new FASB rules (ASC 350-60), Bitcoin holdings are marked to fair value, with unrealized gains/losses flowing through the income statement — making reported net income more volatile than operational cash flows suggest.
CleanSpark (CLSK) Competitors
MARA Holdings (ticker: MARA) is the largest publicly-traded U.S. Bitcoin miner by hash rate, operating 40+ EH/s across multiple sites including Texas. MARA is CleanSpark’s closest peer and the benchmark for U.S. institutional Bitcoin mining. Unlike CleanSpark’s “sell most, hold some” approach, MARA has historically retained a larger portion of mined Bitcoin as a treasury asset — creating a hybrid miner/Bitcoin-treasury investment thesis. MARA tends to have slightly higher electricity costs than CleanSpark but compensates with scale and a larger retained Bitcoin balance.
Riot Platforms (ticker: RIOT) is a Texas-based Bitcoin miner with a significant competitive advantage: access to the ERCOT grid in Texas, where electricity prices can be extremely low (sometimes near zero or even negative during off-peak periods). Riot also participates in demand response programs — getting paid by the grid operator to curtail power consumption during peak demand, effectively earning money when it is NOT mining. Riot’s Texas concentration creates geographic risk but provides among the lowest average power costs in the industry.
Hut 8 (HUT) is a combined U.S./Canadian Bitcoin miner that merged with US Bitcoin Corp in 2024. Hut 8 operates both mining and data center hosting (HPC/AI hosting) — positioning itself as a hybrid mining + digital infrastructure company. This AI/HPC hosting pivot is increasingly common among Bitcoin miners who have power infrastructure but are exploring higher-margin compute workloads.
Core Scientific emerged from bankruptcy protection in January 2024 — one of the most dramatic restructuring stories in crypto mining. Post-restructuring, Core Scientific operates as both a Bitcoin miner and a major data center colocation/hosting provider, including a significant contract to host CoreWeave GPU infrastructure for AI workloads. Core Scientific’s power capacity and site infrastructure make it a direct competitor to CleanSpark for both mining and hosting revenue.
Coinbase is a cryptocurrency exchange, not a Bitcoin miner — it earns revenue from transaction fees and custody services rather than mining. MicroStrategy is a Bitcoin treasury company that holds Bitcoin purchased on the open market (often with leverage) rather than mining it. Both are important Bitcoin ecosystem companies, but they compete in different market segments from CleanSpark.
Block (Jack Dorsey’s fintech company) is building Bitcoin mining hardware (the Block mining chip project) and is developing consumer Bitcoin mining products — a longer-term potential competitive dynamic if the mining hardware market evolves.
Revenue Breakdown
| Revenue Stream | FY2024 | FY2023 | YoY Growth | % of Revenue |
|---|---|---|---|---|
| Bitcoin Mining Revenue | $500M | $300M | +66.7% | 96% |
| Other (Hosting, Equipment) | $20M | $15M | +33.3% | 4% |
| Total Revenue | $520M | $315M | +65.1% | 100% |
All values in millions USD. CleanSpark’s fiscal year ends September 30. Revenue figures are approximate based on annual report disclosures.
The FY2024 revenue growth of +65.1% was driven by two simultaneous tailwinds: (1) Bitcoin’s price appreciation — Bitcoin averaged significantly higher prices in 2024 vs. 2023 as institutional adoption (Bitcoin ETF approvals in January 2024) and the halving narrative drove price appreciation; and (2) hash rate growth — CleanSpark’s operating hash rate grew approximately 3x during FY2024 as the company acquired and optimized new mining facilities. Together, these factors compounded to produce the 65%+ revenue growth despite the April 2024 halving cutting the per-block reward in half.
The “Other Revenue” line (hosting and equipment sales) grew +33.3% but remains a small fraction of total revenue. CleanSpark has not pursued the aggressive HPC/AI hosting pivot that some competitors (Core Scientific, Hut 8) have made — remaining primarily a pure-play Bitcoin miner.
Business Segment Deep-Dives
Bitcoin Mining ($500M, 96% — The Core Business)
Bitcoin mining revenue is determined entirely by three variables: Bitcoin price, CleanSpark’s share of global hash rate, and whether CleanSpark sells immediately upon mining or holds for appreciation.
The facility portfolio: CleanSpark’s primary mining concentration is in Georgia, which offers access to Southern Company’s power grid with competitive rates and reliable power delivery. Georgia has been CleanSpark’s anchor state since its mining pivot in 2020. Additional sites in Mississippi, Wyoming, Tennessee, and Nevada provide geographic diversification that reduces operational concentration risk.
ASIC economics by generation:
| Hardware | Hash Rate | Efficiency | Notes |
|---|---|---|---|
| Bitmain S19 (2020 era) | 95 TH/s | 34.5 J/TH | Now largely obsolete; sold/replaced by CleanSpark in acquisitions |
| Bitmain S19 XP (2022 era) | 140 TH/s | 21.5 J/TH | Still operational at many competitors |
| Bitmain S21 (2024) | 200 TH/s | 17.5 J/TH | CleanSpark’s primary deployment target |
| Bitmain S21 Pro (2024) | 234 TH/s | 15 J/TH | Most efficient available; CleanSpark’s newest deployments |
The move from S19-generation hardware (34.5 J/TH) to S21 Pro (15 J/TH) cuts electricity consumption per unit of hash rate by more than half. This means CleanSpark can double its effective hash rate output from the same power capacity just by upgrading hardware — without needing new facilities or power agreements.
Mining economics per Bitcoin: At $70,000 BTC and $0.04/kWh electricity, CleanSpark’s cash cost to mine one Bitcoin (energy only, excluding depreciation) is approximately $15,000–$20,000 — giving a cash mining margin of 70–80%. Including hardware depreciation (ASICs have a useful life of 2–4 years and are capitalized then depreciated), the all-in GAAP gross margin drops to the 36.5% reported level.
Network difficulty: As more hash rate comes online globally (from CleanSpark, MARA, Riot, and international miners), the Bitcoin network automatically adjusts its difficulty every 2,016 blocks (~2 weeks) to maintain the ~10-minute block time. Rising difficulty means each miner’s share of block rewards declines unless they grow hash rate faster than the network. CleanSpark’s goal: outgrow the network’s difficulty increase by deploying hash rate at a faster rate than the global average.
Hosting and Equipment Sales ($20M, 4% — Margin-Accretive Supplement)
A small but profitable supplement to core mining: charging third parties to host their ASIC hardware at CleanSpark facilities (providing power, cooling, space, and maintenance) and occasional equipment sales (reselling ASICs or other mining hardware). These revenues are higher-margin than mining because they don’t require deploying capital to purchase hardware — CleanSpark earns a service fee on third-party equipment using its existing infrastructure.

All values in millions USD. Financial data sourced from CleanSpark SEC Filings. Figures are approximate.
Reading the income statement: Gross margin held flat at 36.5% — revenue and cost of revenue both grew at ~65%, reflecting that the ratio of Bitcoin price (revenue) to electricity cost (COGS) remained stable. The step-change was in operating income (+167%), driven by operating leverage: operating expenses grew only +50% while revenue grew +65%, as fixed costs (G&A, some stock-based compensation) scale more slowly than revenue. The swing from -$20M net loss to +$50M net profit reflects the operating improvement plus Bitcoin’s price trajectory during the year.
GAAP vs. operational reality: Bitcoin mining GAAP financials can be misleading due to: (1) ASIC depreciation — hardware bought for $100M+ is depreciated over 2–4 years, creating large non-cash COGS charges that reduce reported gross margin below the cash mining margin; (2) stock-based compensation — Bitcoin miners heavily use equity compensation, which is a real economic cost but non-cash; and (3) Bitcoin fair value adjustments — under new FASB rules, Bitcoin on balance sheet is marked to market. Analysts typically use “cash mining cost per Bitcoin” and adjusted EBITDA as the primary operational metrics.
CleanSpark (CLSK) Key Financial Metrics
| Metric | FY2024 Value | What It Means |
|---|---|---|
| Total Revenue | $520M (+65.1%) | Driven by Bitcoin price + hash rate growth; will fluctuate with BTC price |
| Gross Margin | 36.5% | Reflects energy cost + ASIC depreciation; cash mining margin is ~70%+ |
| Operating Margin | 7.7% | +290 bps YoY; operating leverage kicking in as revenue scales over fixed costs |
| Net Income | $50M (vs. -$20M) | Profitable at current Bitcoin prices; would turn negative if BTC fell significantly |
| Hash Rate | ~30 EH/s (year-end) | CleanSpark’s claim on global Bitcoin block rewards; target 50+ EH/s |
| Electricity Cost | ~$0.035–$0.045/kWh | Key competitive advantage; lower = lower breakeven Bitcoin price |
| Cash Mining Margin | ~70–80% (est.) | Revenue minus electricity cost only (before depreciation); true operational efficiency |
| Capital Expenditure | ~$500M+ | ASIC hardware purchases + facility acquisitions; funded primarily by equity |
| Bitcoin on Balance Sheet | Some retained BTC | Fair value marked to market; gains/losses flow through net income |
| Share Dilution | Ongoing (ATM equity) | Primary funding mechanism; share count growth dilutes per-share economics |
Key Metric Observations
The 36.5% gross margin is deceptively low. In cash terms — revenue minus electricity cost only — CleanSpark’s mining margin is approximately 70–80%. The difference is ASIC hardware depreciation: CleanSpark has deployed hundreds of millions in hardware that is depreciated over its useful life, creating large non-cash charges in cost of revenue. This is structurally similar to how manufacturing companies show lower gross margins than pure-service businesses — the capital investment shows up in depreciation within COGS.
Operating leverage is the FY2024 story. Revenue grew +65% while operating expenses grew only +50%, expanding operating margin by 290 bps. As the mining fleet reaches full utilization and facility acquisition pace normalizes, operating expenses should grow more slowly than revenue — creating continued margin expansion even without Bitcoin price appreciation.
Hash rate growth outpacing the network is the strategic imperative. If CleanSpark’s hash rate grows 3x in a year but the global network only grows 2x, CleanSpark captures a larger share of all Bitcoin mined. In a world where block rewards are fixed (3.125 BTC per block), growing your network share percentage is the only way to increase Bitcoin production independent of BTC price.
Is CleanSpark (CLSK) Profitable?
Conditionally — and cyclically. CleanSpark reported $50M net income in FY2024, but profitability is directly tied to Bitcoin’s market price. If Bitcoin had been $30,000 instead of ~$65,000+ during FY2024, revenue would have been roughly half ($260M) while costs remained largely fixed — likely producing significant losses.
The key profitability threshold: CleanSpark estimates its all-in break-even Bitcoin price (including electricity, depreciation, G&A, and SBC) at approximately $40,000–$50,000 at current hash rates and difficulty levels. Below that price, GAAP profitability deteriorates. Above it, margins expand rapidly due to the high operating leverage in the model.
EBITDA perspective: Adjusted EBITDA (adding back depreciation and stock-based compensation to operating income) paints a more favorable picture. ASIC depreciation alone runs into the hundreds of millions annually for a 30 EH/s fleet — adding that back produces adjusted EBITDA margins well above the 7.7% GAAP operating margin.
Free cash flow: Likely negative despite net income profitability, because CleanSpark is spending $500M+ annually on hardware and facility acquisitions that are capitalized (not immediately expensed). FCF will turn positive when growth capex normalizes — a key milestone the market will watch for as a signal of business maturity.
Where Does CleanSpark Spend its Money?
Energy / Electricity (~40–50% of COGS)
The largest variable cost. CleanSpark’s total electricity consumption at 30 EH/s (assuming ~20 J/TH fleet average) is approximately 600 megawatts — roughly the power demand of a small city. At $0.04/kWh, that’s ~$210M annually in electricity alone. Long-term power purchase agreements (PPAs) with utilities in Georgia, Mississippi, Wyoming, and elsewhere lock in rates and provide revenue predictability for facility capex planning. Energy cost management — securing cheap, reliable power — is the central operational discipline of Bitcoin mining.
ASIC Hardware Depreciation (~30–40% of COGS)
ASICs are capitalized when purchased and depreciated over their useful life (typically 2–4 years). With CleanSpark’s fleet valued at hundreds of millions of dollars, annual depreciation runs deep into COGS — creating the gap between the ~70%+ cash mining margin and the 36.5% GAAP gross margin. This depreciation is non-cash but real: it represents the economic cost of hardware that will eventually need to be replaced (usually with newer, more efficient models) to remain competitive as the network’s hardware efficiency improves.
Hardware Purchases (Capital Expenditure) (~$500M+/year)
The largest cash outflow — buying new ASIC hardware (Bitmain S21, S21 Pro, and next-generation models as they become available). Bitcoin mining hardware has an effective competitive life of ~2–4 years before newer-generation hardware makes it economically suboptimal to operate. CleanSpark must continuously reinvest in hardware to maintain its position in the efficiency curve. This constant reinvestment cycle, funded primarily by equity issuance, is the primary driver of share count growth and share dilution.
Facility Acquisitions and Infrastructure
Purchasing mining sites — land, buildings, electrical infrastructure, cooling systems — from distressed operators or greenfield development partners. Post-halving 2024 was the most active acquisition period in the company’s history. Facility capex is separate from hardware capex and often structured as real estate acquisitions with associated infrastructure upgrades.
Stock-Based Compensation (~$50–100M/year estimated)
Bitcoin mining companies heavily compensate employees and executives with equity. SBC is non-cash but dilutive to shareholders. The SBC line is a major contributor to why GAAP operating expenses ($150M) are high relative to revenue — much of that figure is non-cash equity compensation. Adjusting for SBC gives a cleaner picture of the cash cost structure.

CleanSpark (CLSK): What to Watch
1. Bitcoin Price: The Primary Revenue Driver Every $10,000 move in Bitcoin’s price represents approximately $100M+ in annualized revenue impact at current hash rates. CleanSpark’s entire profitability thesis is leveraged to Bitcoin — a sustained Bitcoin below $40,000–50,000 likely pushes the company back to GAAP losses, while Bitcoin above $80,000–100,000 produces very high margins. Investors in CLSK are making a directional bet on Bitcoin as much as on CleanSpark’s operational execution.
2. Hash Rate Growth: Outpacing Global Network Difficulty The global Bitcoin network’s hash rate grows continuously as new miners come online. CleanSpark must grow its hash rate faster than the network average to maintain or increase its share of block rewards. Target: 50+ EH/s. Watch quarterly hash rate disclosures and compare to network difficulty growth (publicly available on blockchain explorers). Falling behind network growth means dilution of Bitcoin production even at flat Bitcoin prices.
3. Electricity Cost: The Most Controllable Profitability Lever Power costs are the one variable that CleanSpark can influence through contracting and site selection. Watch for any disclosures about power agreement renewals, new state launches, or utility rate changes at existing sites. The difference between $0.03/kWh and $0.05/kWh electricity cost on a 600-megawatt fleet is approximately $105 million annually — a difference that directly flows through to gross margin.
4. Share Dilution Rate: The Hidden Return Killer CleanSpark funds growth primarily by selling new shares via ATM equity programs. A company that doubles its hash rate (and doubles its Bitcoin production) but also doubles its share count has created no per-share value improvement. Monitor diluted share count growth in quarterly filings and evaluate the company’s capital efficiency: how much hash rate per new share issued? The best outcome is hash rate growing faster than share count.
5. ASIC Fleet Efficiency: J/TH as Competitive Moat The energy efficiency of the mining fleet (joules per terahash) determines the electricity cost per Bitcoin mined. Companies with older, less efficient hardware (S19 series at 34+ J/TH) face a structural cost disadvantage vs. operators running S21 Pro at 15 J/TH. CleanSpark has been aggressive in hardware upgrades, but watch for: (a) pace of next-generation hardware orders (Bitmain S21 Pro+, potential NVIDIA/custom ASIC development), (b) utilization rate of current fleet, and (c) hardware delivery timelines that could slow hash rate growth.
6. Bitcoin Halving Cycle Positioning (~2028 Next Halving) The next halving (~2028) will cut the block reward from 3.125 to 1.5625 BTC per block. CleanSpark’s viability at that point depends on: (a) Bitcoin’s price being significantly higher than today to maintain per-block dollar revenue, and (b) the company having scaled hash rate while driving electricity costs further down. The long-run Bitcoin mining thesis requires that transaction fees (which miners also collect) grow to supplement declining block subsidies — an unproven but important assumption.
7. AI/HPC Hosting: The Pivot Question Bitcoin miners have significant power infrastructure — large, well-connected facilities with substantial megawatt capacity and cooling systems. These are also the requirements for AI/GPU computing infrastructure. Core Scientific and Hut 8 have signed major contracts to host GPU clusters for AI workloads (CoreWeave, Microsoft HPC demand). CleanSpark has not made a major pivot in this direction. The strategic question: does CleanSpark maintain pure-play Bitcoin mining focus, or diversify into higher-margin AI computing hosting? Either choice has significant implications for capex allocation, revenue diversification, and the company’s risk/return profile.
8. Regulatory Environment: Bitcoin Mining and Energy Policy Bitcoin mining’s high electricity consumption has attracted regulatory scrutiny in some states (New York banned proof-of-work mining in 2022; other states have considered similar measures). Environmental concerns about the carbon footprint of mining (even when using utility grid power) could lead to additional regulations, disclosure requirements, or restrictions. CleanSpark’s “clean” branding (the company emphasizes sustainable energy sourcing where possible) is partly a hedge against this risk. Monitor: state-level energy legislation in Georgia, Mississippi, and Wyoming; federal environmental disclosure rules for energy-intensive industries.
CleanSpark (CLSK) Financial Summary
CleanSpark (CLSK) is one of the largest pure-play U.S. Bitcoin miners, operating 30+ EH/s of hash rate across facilities in Georgia, Mississippi, Wyoming, Tennessee, and Nevada. The company generated approximately $520 million in FY2024 revenue — up +65.1% year-over-year — almost entirely from Bitcoin mining operations ($500M, 96%). Gross margin of 36.5% reflects the combined cost of electricity and ASIC hardware depreciation; the underlying cash mining margin (excluding depreciation) is approximately 70–80%.
Operating margin expanded to 7.7% (+290 bps) as operating leverage took hold — revenue grew faster than fixed operating expenses. Net income swung from -$20M to +$50M, the company’s first meaningful GAAP profitability, driven by Bitcoin price appreciation and disciplined cost management.
The investment thesis: CleanSpark provides leveraged exposure to Bitcoin’s price through operational efficiency — targeting electricity costs of $0.035–0.045/kWh, deploying next-generation ASIC hardware (S21 Pro at 15 J/TH), and growing hash rate through post-halving acquisitions of distressed competitors. The primary risks are Bitcoin price volatility (the entire business model collapses in a sustained bear market), share dilution from equity-funded growth, and rising global network difficulty that erodes each miner’s proportional share of block rewards.
Related companies include MARA Holdings, Riot Platforms, Hut 8, Coinbase, MicroStrategy, and Block.
Frequently Asked Questions
How does CleanSpark make money? By mining Bitcoin with specialized ASIC computers and selling the mined coins for U.S. dollars. FY2024: ~$520M revenue (+65.1%), 96% from Bitcoin mining. Revenue = BTC mined × Bitcoin price. BTC mined = CleanSpark’s % of global hash rate × total daily BTC issued.
What is Bitcoin mining hash rate? Hash rate (measured in EH/s) is the computing power dedicated to Bitcoin mining. CleanSpark’s hash rate grew from ~9 EH/s to 30+ EH/s during 2024. A higher hash rate = a larger proportional share of all Bitcoin block rewards issued globally.
Is CleanSpark profitable? Conditionally — profitable at current Bitcoin prices (~$50,000+ breakeven), not profitable in a Bitcoin bear market. FY2024: $50M net income (vs. -$20M prior year), 7.7% operating margin, 36.5% gross margin.
What happened after the April 2024 Bitcoin halving? Block rewards were cut from 6.25 to 3.125 BTC per block, halving miner revenue per unit of hash rate. Bitcoin’s price appreciation partially offset this. Weaker miners sold facilities — CleanSpark was a major buyer, growing hash rate 3x during 2024.
Who are CleanSpark’s main competitors? MARA Holdings (largest by hash rate), Riot Platforms (lowest power costs via ERCOT), Hut 8 (U.S./Canadian hybrid miner), and Core Scientific (mining + AI hosting). Note: Coinbase (exchange) and MicroStrategy (Bitcoin treasury) are different Bitcoin ecosystem businesses, not direct mining competitors.
What is CleanSpark’s electricity cost? $0.035–$0.045/kWh target — among the lowest in U.S. public mining. Lower electricity = lower breakeven Bitcoin price = profitable across a wider price range. Electricity is the primary variable cost (40–50% of cost of revenue).
What is the risk of share dilution at CleanSpark? Very real. CleanSpark funds expansion primarily through ATM equity offerings (selling new shares). This grows the share count, diluting each shareholder’s claim on mined Bitcoin. Investors must evaluate hash rate growth vs. share count growth to assess per-share value creation.
What is the next Bitcoin halving and when? Approximately 2028, cutting the block reward from 3.125 BTC to 1.5625 BTC. Historically, Bitcoin’s price has appreciated after halvings (reduced supply meeting steady demand). CleanSpark’s viability post-2028 depends on Bitcoin being significantly higher-priced and transaction fees growing to supplement falling block subsidies.
