Three years of building one of the largest domestic Bitcoin mining operations didn't win CleanSpark many fans. The market saw a commodity business - power costs, hash rate, block rewards - and valued it accordingly. What the market missed is that accumulating a gigawatt of contracted US power is extraordinarily difficult and extraordinarily valuable. You cannot buy it from Amazon. You cannot build it in six months. It takes a decade of relationships with utility commissions, land developers, and grid operators.
CleanSpark now owns that gigawatt. It also earned $766 million in FY2025 revenue at 55% gross margins, repurchased 11% of its own outstanding shares, holds over 13,000 Bitcoin on the balance sheet - mined, not purchased - and issued a $1.15 billion convertible at 0% interest to fund what comes next. What comes next is AI data centers.
The narrative is shifting. In late November 2025, a senior director of site selection from a global hyperscaler called the CEO the evening of the earnings call to confirm they were "still in the running" for the Sandersville, Georgia facility. That call was not from a neocloud. It was from a hyperscaler. The demand is institutional, the timeline is 2026–2027, and the re-rating - when it arrives - will not be gradual.
We are building a position at what we believe to be the inflection point between recognition and repricing. The downside is protected by a hard cost floor on the Bitcoin business. The upside is carried by a land bank that the market is currently valuing at zero.
1+ Gigawatt of Contracted US Power
The asset that took a decade to build and cannot be replicated in the current grid environment
Bitcoin Mining
The cash engine that finances everything else. 50 EH/s of fully owned, 100% US-based infrastructure generating revenue at a 55% gross margin, with the world's most efficient immersion-cooled fleet.
- FY2025 Revenue$766 million
- Gross Margin55%
- Marginal Cost / BTC~$43,000
- BTC Treasury13,054 coins
- Hashrate50 EH/s
- Fleet Efficiency13.5 J/TH (S21 XP)
AI Data Centers
The optionality the market is currently pricing at zero. $0 AI revenue today - but two dedicated sites are being commercialised for hyperscaler tenants, with industry contracts benchmarking at $1–$1.5M per MW per year.
- Sandersville Capacity250 MW (AI-ready)
- Texas Capacity285 MW (ERCOT approved)
- First TX EnergizationH1 2027 (200+ MW)
- AI Head (Jeff Thomas)ex-President, Humain
- Modular PartnerSubmer (MOU signed)
- Revenue Potential (535 MW)$535M–$800M / yr
Bitcoin Profitability Across Three Market Scenarios
With a $43K marginal cost per coin, CLSK remains profitable even in a severe BTC correction - a critical margin of safety the market consistently overlooks
Reasons to Act Now
Reasons to Wait / Risk Factors
Relative to Bitcoin mining and AI-pivot peers, CleanSpark offers the widest margin of safety on earnings multiples while building comparable power infrastructure. The re-rating from 11× to 30×+ has historically happened at the moment of a signed hyperscaler contract.
| Company | FY26 P/E | P/Sales (NTM) | P/Book | AI Revenue | Power (MW) | Assessment |
|---|---|---|---|---|---|---|
| CleanSpark (CLSK) | 11.6× | 2.98× | 1.3× | $0 (building) | 1,000+ MW | Cheapest in group |
| IREN Limited (IREN) | 40× | 8×+ | 3.5× | Yes - signed | ~800 MW | Priced for AI pivot |
| Cipher Mining (CIFR) | 48× | 10×+ | 6×+ | Yes - signed | ~500 MW | Full AI premium |
| MARA Holdings (MARA) | 232× | 4× | 2.5× | No | ~700 MW | BTC treasury premium |
| Riot Platforms (RIOT) | Loss | 5× | 2× | No | ~700 MW | Unprofitable miner |
Our target range of $20–$24 assumes BTC holds above $85K and a signed AI tenant contract by H2 2026. Below are three paths with share price implications.
Bear Case
Crypto winter / AI hype collapses
Base Case
Stable macro, AI contract in 2026
Bull Case
BTC resumes + AI re-rating premium
Ordered by expected impact on share price. The first signed AI tenant agreement would be the single most important near-term catalyst - it is the event that re-rates every comparable peer.
19,000 S21 XP Immersion Miners Deployed
Adds ~6 EH/s to existing 50 EH/s fleet with industry-leading 13.5 J/TH efficiency. Deployment was deliberately delayed to preserve AI-applicable megawatts - deployment confirms AI-first capital discipline is real.
First Hyperscaler / AI Tenant LOI or Agreement (Sandersville)
The single most important near-term catalyst. CEO confirmed multiple inbound inquiries including direct hyperscaler engagement. A signed lease at Sandersville would validate 250 MW at $1–$1.5M/MW/year and trigger peer-style multiple expansion from 1.3× to 3–5× book.
Texas Lease Signed + Submer Factory Modules Ordered
Sealy, TX (285 MW, ERCOT approved) is being marketed simultaneously. A signed lease here - plus first modular orders from Submer - gives visibility on ~$400–500M of annual AI revenue from 2027. Behind-the-meter gas generation opportunity evaluation also expected.
New Land & Power Acquisitions (Multi-Gigawatt Pipeline)
Management explicitly stated they are hunting for additional power with remaining convertible proceeds. Each new GW acquisition extends the infrastructure moat and raises the long-term platform ceiling. Expect announcements in parallel with AI commercialization.
Texas First 200 MW Energized - AI Revenue Begins
ERCOT approval complete. This is the ultimate proof-of-concept milestone - the moment CleanSpark shifts from being valued as a miner to being valued as an infrastructure company. Sustainable recurring AI/HPC revenue changes the company's fundamental identity.
Texas 240 MW Tranches (×2) - Platform Scale
Two further 240 MW tranches scheduled for 2028 and 2029, bringing total Texas capacity to 725 MW. Combined with Sandersville and future acquisitions, this positions CLSK in the same tier as established neocloud operators. Potential for project-level debt financing at 80%+ LTV from 2027.
Bitcoin Price Dependency
100% of current revenue is tied to BTC price. A sustained bear market below $65K significantly impairs earnings, forces BTC sales from treasury, and likely delays AI capex spending. This is the dominant risk - do not size this position without a view on BTC.
AI Contract Timeline Risk
CEO acknowledged "it's hard to say" whether Sandersville tenant deals close in 2026. If lease agreements slip to 2027 or later, the re-rating thesis is delayed and capital burn accelerates. Contract announcements are binary catalysts - the absence of news is not neutral.
Build Cost & Execution Risk
AI/HPC infrastructure costs $10M per MW - 10× the cost of Bitcoin mining build-out. CLSK has never built an AI data center. First-project execution risk is real, and the Submer partnership, while promising, is unproven at scale domestically.
Dilution & Capital Structure
Share count grew ~50% from 2022–2025 before the 2025 buyback. If AI revenues take longer than expected and BTC weakens simultaneously, management may need to issue equity again. The $1.15B convertible at 27.5% premium matures in 2032 - but conversion risk is real above ~$15.
Q1 FY2026 Results Validate the Thesis
CleanSpark reported Q1 FY2026 revenue of $181 million - below the elevated FY2025 pace of $766 million annualised, reflecting the post-halving reset in Bitcoin mining economics. That comparison is expected and does not undermine the thesis. What validates the thesis is not the absolute revenue level relative to a halving-distorted prior year, but the margin structure and hashrate trajectory: the company continues to operate at approximately 55% gross margins with a $43K/coin cost basis and a 50+ EH/s fleet - preserving profitability across a wide range of Bitcoin price scenarios. The company simultaneously reported balance sheet strengthening and further advances on its multi-gigawatt AI infrastructure platform, confirming that the power portfolio expansion and AI commercialization timeline remain on track. The growth thesis is anchored in operational capacity expansion and AI monetization, not a straight-line revenue comparison across halving-distorted periods.
As of the time of this update, the core thesis is intact: BTC mining generates the cash, and the land-and-power bank is being actively monetised for AI tenants. The first lease agreement remains the primary near-term re-rating catalyst to watch.

CLSK - CleanSpark, Inc. (NASDAQ)
Stop discipline: A close below $8.50 would breach the 2024 demand zone and invalidate the higher-lows pattern, suggesting the BTC cycle has turned more bearish than our base case. Exit the position and re-assess.
Position sizing note: This is a high-volatility, BTC-correlated position. Size accordingly. The 52-week trading range has historically shown a 4× spread between low and high. Options may be a more capital-efficient vehicle for speculative exposure if equity volatility is unacceptable.
