CleanSpark, Inc. (CLSK) Stock Price & How to Invest
Short answer
You can invest in CleanSpark (CLSK) by buying shares or fractional shares at any major broker, through an ETF that holds it, or as one holding in a thematic basket. CleanSpark is a US-based, pure-play bitcoin miner that runs roughly 50 EH/s of low-cost hash rate and holds a large bitcoin treasury of around 13,600 BTC (as of June 2026), so the stock behaves largely as a leveraged proxy on the price of bitcoin. The biggest risk is that exposure cuts both ways: a falling bitcoin price, post-halving block-reward economics, and the share dilution miners use to fund expansion can each pressure the stock hard.

What does CleanSpark, Inc. (CLSK) do?
CleanSpark is a Las Vegas-based bitcoin mining company that operates data centers, mostly in the southeastern United States, packed with specialized ASIC machines that compete to validate bitcoin transactions and earn newly minted coins plus fees. It makes money primarily by selling some of the bitcoin it mines and by keeping the rest on its balance sheet as a treasury; reported metrics that matter most are operational hash rate (about 50 EH/s as of early 2026), cost to mine each coin (roughly $44,800 in the most recent quarter), and the size of the bitcoin stack it holds (around 13,600 BTC). Because revenue is paid in bitcoin and a chunk of the balance sheet is bitcoin, both the income statement and reported book value swing with the crypto price.
The company began life as a microgrid and energy-software business and pivoted into bitcoin mining around 2020, then scaled aggressively through self-built and acquired sites, emphasizing low electricity costs (recently near 5 to 6 cents per kWh). More recently CleanSpark has begun positioning its roughly 1.8 GW of contracted power, land, and data centers as a platform that could also host AI and high-performance computing workloads, and management has discussed advanced talks with a potential large hyperscaler tenant. That makes it both a pure-play miner today and a possible energy-infrastructure story tomorrow.
What's driving CleanSpark, Inc. (CLSK)?
Scaled, low-cost hash rate
CleanSpark reached roughly 50 EH/s of operational hash rate in early 2026, placing it among the largest US miners. Its pitch is efficiency: a recent all-in cost to mine of about $44,800 per bitcoin and power costs near 5 to 6 cents per kWh, which it says are well below the industry average. Lower marginal cost means the business can stay cash-generative at bitcoin prices that squeeze higher-cost peers.
Cheap-power energy footprint
The company controls more than 1.8 GW of power, land, and data centers across the US, much of it secured at competitive energy prices. That contracted power is the core asset and the moat: it is hard to replicate quickly and gives CleanSpark optionality in how it deploys electrons. Power procurement and uptime are the operational levers that most directly drive mining margins.
Bitcoin treasury optionality
Rather than selling everything it mines, CleanSpark holds a large bitcoin treasury, around 13,600 BTC as of June 2026, with a reported HODL value near $925 million at quarter-end. This makes the stock a leveraged bet on bitcoin's price, which amplifies gains in rallies and losses in drawdowns. Treasury value flows through reported results as mark-to-market swings, so headline net income can be dominated by non-cash bitcoin moves.
Possible AI and HPC pivot
CleanSpark has begun directing capital toward converting parts of its power and data-center footprint into AI and high-performance-computing capacity, and management has cited advanced discussions with a potential investment-grade hyperscaler tenant. If executed, long-term contracted HPC revenue could diversify away from pure bitcoin exposure. This is early-stage optionality, not yet a proven, contracted revenue line, and competes with peers like Core Scientific and IREN that moved earlier.
What are the risks to CleanSpark, Inc. (CLSK)?
CLSK carries direct bitcoin price exposure: when bitcoin falls, mining revenue and the treasury both decline, and the stock has historically moved more than bitcoin itself. Block-reward halvings (the last in 2024) cut the bitcoin paid per block, so miners must keep lowering costs or growing hash rate just to stand still, and rising network difficulty erodes each machine's output. Funding expansion has often meant issuing new shares or debt, diluting existing holders, and recent quarters showed large GAAP losses (a roughly $378 million net loss in the quarter ended March 2026, much of it non-cash bitcoin marks) and negative adjusted EBITDA. Energy-cost spikes, equipment cycles, and shifting US crypto and energy regulation add further uncertainty.
How is CleanSpark, Inc. (CLSK) valued? (approximate, June 2026)
A simple financial snapshot. These are approximations and refresh quarterly; for current figures see CleanSpark, Inc.'s investor relations page or your broker.
- Quarterly revenue (FQ2 2026): ~$136 million (down ~25% YoY)
- Operational hash rate: ~50 EH/s
- Bitcoin held (treasury): ~13,600 BTC
- Adjusted EBITDA (FQ2 2026): ~-$241 million
- Cost to mine per bitcoin: ~$44,800
- Market cap: ~$4.0 to $4.5 billion
CleanSpark's reported results are tightly correlated with the price of bitcoin: the quarter ended March 2026 showed a large net loss driven mostly by non-cash mark-to-market adjustments on its bitcoin holdings as the coin's average price fell toward the mid-$70,000s. Revenue, margins, and book value can all swing sharply quarter to quarter, so single-period figures say more about bitcoin's level than about a durable trend. These figures are approximate and tied to the asOf date; check the latest filings before relying on them.
Who competes with CleanSpark, Inc. (CLSK)?
Large US bitcoin miners
Riot Platforms (RIOT) and MARA Holdings (MARA) are the closest scaled, US-listed pure-play comparisons, each running large hash rate and holding sizable bitcoin treasuries. They compete with CleanSpark for power, ASIC supply, and investor capital, and their stocks tend to move together with bitcoin.
Miners pivoting to AI and HPC
Core Scientific (CORZ) and IREN moved earlier to convert mining power into AI and high-performance-computing hosting, making them the benchmark for CleanSpark's own HPC ambitions. Bitfarms and Bitdeer are also repositioning toward AI buildouts while continuing to mine.
Direct bitcoin exposure
For investors who want bitcoin's price without operating risk, spot bitcoin ETFs and bitcoin-treasury companies are the main alternatives. A miner like CLSK adds operating leverage, hash-rate growth, and dilution risk on top of the underlying coin's moves.
How to invest in CleanSpark, Inc. (CLSK)
There are three common ways to get CLSK exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so CLSK sits alongside other stocks that express the same thesis.
Walnut takes the basket route. Describe a thesis where CLSK fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.
The bottom line on CleanSpark, Inc. (CLSK)
CleanSpark is, today, one of the larger and lowest-cost US bitcoin miners, running about 50 EH/s of operational hash rate and holding roughly 13,600 BTC as a treasury (as of June 2026), with an emerging push to convert its ~1.8 GW power pipeline into AI and high-performance-computing capacity. If you believe in a scaled, cheap-power bitcoin miner with treasury and HPC optionality, the question becomes sizing and overlap with bitcoin you may already hold, not timing; the risk is that the stock amplifies bitcoin's moves in both directions and that mining margins and share count are sensitive to the next halving, energy costs, and capital raises.

FAQ
Is CLSK a good stock to buy right now?
+
That depends on your goals, time horizon, and tolerance for volatility, and this is not advice. The bull case is a scaled, low-cost miner (about 50 EH/s, sub-6-cent power) with a large bitcoin treasury and emerging AI optionality. The bear case is direct bitcoin price exposure, large recent losses, and dilution. Many holders treat it as a high-risk, bitcoin-correlated position to size small.
What does CleanSpark do?
+
CleanSpark operates US data centers full of specialized machines that mine bitcoin, earning newly issued coins and transaction fees. It runs roughly 50 EH/s of hash rate and controls more than 1.8 GW of power. It makes money by selling some mined bitcoin and holding the rest as a treasury, and it is beginning to explore hosting AI and high-performance-computing workloads on its power footprint.
Is CLSK a good way to invest in bitcoin?
+
CLSK gives leveraged, indirect exposure to bitcoin rather than the coin itself. When bitcoin rises, a low-cost miner with a treasury can outperform it; when bitcoin falls, the stock often drops more because mining margins and treasury value both shrink. Investors wanting cleaner exposure sometimes prefer a spot bitcoin ETF, while CLSK adds operating and dilution risk. This is descriptive, not advice.
Does CLSK pay a dividend?
+
No. CleanSpark does not pay a dividend. Like most bitcoin miners, it reinvests cash flow into expanding hash rate, building data centers, securing power, and accumulating its bitcoin treasury. Any return to shareholders would come from share-price changes rather than income, and the share count has grown over time as the company has raised capital to fund growth.
How does a bitcoin halving affect CleanSpark?
+
Roughly every four years the bitcoin protocol halves the reward miners earn per block; the most recent halving was in 2024. That immediately cuts the bitcoin a miner produces from the same machines, so CleanSpark must lower costs, grow hash rate, or rely on a higher bitcoin price to offset it. Halvings are a structural headwind that pressures higher-cost miners most.
Why is CLSK so volatile?
+
CleanSpark's revenue is paid in bitcoin and a large part of its balance sheet is bitcoin, so both earnings and book value move with the crypto price. On top of that, mining adds operating leverage from fixed power and equipment costs. The result is a stock that has historically swung more than bitcoin itself, in both directions, which is why position sizing matters to many holders.
Is CleanSpark moving into AI and data centers?
+
It is beginning to. CleanSpark has signaled it will direct capital toward converting parts of its roughly 1.8 GW power and data-center footprint into AI and high-performance-computing capacity, and management has discussed advanced talks with a potential large hyperscaler tenant. As of June 2026 this is early-stage optionality rather than a proven, contracted revenue stream, so it should be weighed as upside, not a certainty.
How can I add CLSK to a thematic basket?
+
In an app like Walnut you can hold CLSK as one constituent in a basket built around a thesis such as bitcoin mining, crypto infrastructure, or energy-plus-compute, set a target weight, and place fractional orders through a connected broker to reach that weight. Holding it inside a basket makes it easier to track how the position performs against your stated thesis and the rest of your holdings.
