CleanSpark Borrows $1.15B at 0% to Survive the Brutal Bitcoin Mining Shakeout
CleanSpark simply offered $1.15 billion of zero-coupon convertible notes to purchase extra energy and machines in the most brutal mining atmosphere but.
The deal is a 144A non-public placement due in 2032, with an preliminary conversion value of round $19.16, roughly a 27.5% premium to the $15.03 inventory value at the time of announcement.
Approximately $460 million is allotted instantly to repurchasing CleanSpark shares from the notice patrons, with the the rest used to broaden energy and land portfolios, construct information middle infrastructure, together with AI and high-performance computing capability, repay Bitcoin-backed credit score strains, and canopy normal company bills.
That single transaction is a cheat sheet for the place miner economics stand in 2025. The phrases reveal who survives, who will get consolidated, and what it truly prices to keep related in a community that has simply crossed one zettahash per second of worldwide hashrate.
Whether the guess pays off relies upon much less on narrative and extra on whether or not money flows can help a stability sheet that now carries over $1.7 billion in long-term debt in opposition to a treasury of roughly 12,100 BTC.
Zero % means one thing
A zero-coupon convertible notice of this dimension means that credit score traders are comfy being paid in fairness optionality moderately than money curiosity.
They’re betting that CleanSpark will stay solvent regardless of a number of difficulties and value cycles, and keep ample liquidity in fairness for eventual conversion.
That’s a cost-of-capital benefit in contrast to smaller miners, which regularly resort to costly fairness dilution or high-yield debt with double-digit coupons. In 2025, solely the most effective miners can borrow this a lot at zero %. Everyone else is paying up or getting consolidated.
However, the construction carries threat. It’s a leveraged guess on each Bitcoin value and CleanSpark fairness efficiency. If execution stumbles or Bitcoin underperforms, the converts change into a delayed dilution bomb.
If the inventory trades properly above $19.16, present shareholders get diluted as notice holders convert. The share buyback complicates the image additional, as CleanSpark is utilizing $460 million of borrowed cash to repurchase its personal inventory from the similar traders shopping for the notes.
That indicators administration thinks the fairness is undervalued, but it surely additionally means much less capital obtainable for precise growth. After the buyback, roughly $670 million stays for capital expenditures and debt compensation.
Capex and scale in a one-zettahash world
New-generation mining rigs, together with their related infrastructure, sometimes price between $6 million and $10 million per exahash per second of capability.
If CleanSpark deployed all incremental capital into mining, which is unlikely given the deal with AI and information facilities, that $670 million might fund 70 to 110 exahashes of extra capability.
In a community already above 1,000 exahashes, even half that may cement CleanSpark as a top-tier hashrate participant.
A significant chunk additionally flows into energy websites and AI or HPC build-outs, however the sign is evident: 2025 miner economics at the moment are “go large or get eaten.”
Capital depth is exploding past simply shopping for rigs. Miners are constructing vertically built-in energy and data center campuses, treating hashpower as a part of a broader infrastructure play moderately than a standalone guess on block rewards.
CleanSpark concluded its fiscal second quarter with roughly 42.4 exahashes per second and a said objective of surpassing 50 exahashes by 2025, representing round 4.9% of the world hashrate at present ranges.
The elevate positions them to push additional, but it surely additionally highlights the “treadmill” downside. The community hashrate continues to climb, the problem adjusts upward, and every exahash generates fewer Bitcoins over time.
Post-halving and post-one-zettahash, staying in place requires fixed reinvestment to keep income per unit of capability.
Post-halving margin stack
CleanSpark’s fiscal numbers for the second quarter present income up 62.5% year-over-year to $181.7 million, however a web lack of $138.8 million and destructive adjusted EBITDA. Cost to mine got here in round $42,700 per Bitcoin, positioning them on the environment friendly finish of the curve.
At roughly $103,000 Bitcoin, that suggests a gross mining margin round 55% to 60% earlier than promoting, normal and administrative bills, curiosity, internet hosting, and different overhead.
Energy prices alone accounted for 46% of Bitcoin’s income in the second quarter.
That’s the post-halving actuality: block subsidy halved, community hashrate at all-time highs, and hashprice compressed to ranges that squeeze everybody however the most effective operators.
Only miners with low-cost, secure energy, significant scale, and entry to low or zero-coupon capital can hold constructive margins after mounted prices.
The 2024 halving didn’t kill miners outright, however bifurcated them as an alternative. CleanSpark’s elevate says which facet of that divide it intends to occupy.
Smaller miners with out locked-in energy offers or environment friendly fleets are both shuttering websites, promoting property, or elevating dilutive fairness by way of at-the-market applications.
CleanSpark is doing the reverse, elevating debt-like capital with a simultaneous buyback, signaling confidence that future hashrate and Bitcoin holdings justify present fairness valuations.
AI facet quests: diversification or narrative sugar?
CleanSpark’s use of proceeds explicitly consists of “information middle infrastructure” and AI or HPC capability. That language mirrors a broader industry trend as Core Scientific, Iris Energy, Hut 8, and TeraWulf pitch HPC and AI internet hosting as higher-margin makes use of for his or her energy and infrastructure.
The market has grown skeptical of “AI pivot” slides with out signed contracts and clear unit economics.
The framework to decide whether or not that is actual diversification comes down to the income construction. Will the AI builds be contracted, dollar-denominated, multi-year agreements that de-risk income? Or is that this “we’d host AI sometime” optionality that competes with Bitcoin mining for capital however doesn’t ship near-term money flows?
AI and HPC internet hosting can generate regular, predictable income if appropriately contracted. However, these {dollars} compete instantly with the incremental Bitcoin mined per megawatt, in addition to the optionality worth of holding self-mined Bitcoin in the treasury.
Every greenback CleanSpark spends constructing AI capability is a greenback not deployed into hashpower, and the return profile is basically completely different.
Bitcoin mining gives leveraged publicity to Bitcoin value appreciation. AI internet hosting gives utility-like income with decrease volatility but in addition decrease upside.
Separating narrative from money flows
The professional forma capital stack now consists of roughly $640 million in present debt, plus $1.15 billion in new convertible debt, in opposition to fairness, and a Bitcoin treasury value roughly $1.25 billion at $103,000 per Bitcoin.
No curiosity expense in the close to time period helps margins, however the fairness overhang looms if CleanSpark trades properly above the $19.16 conversion value.
Return on invested capital performs out in two situations. The bull case rests on Bitcoin staying at or above $100,000, the hash value stabilizing, and the added exahashes, mixed with low-cost zero-percent notes, creating robust free money circulation leverage.
On the different hand, the bear case includes Bitcoin dropping or the hash value compressing additional as extra hashrate comes on-line, new capability earns much less, and dilution threat materializes with weaker fairness.
The rise indicators consolidation part circumstances. Cheap capital and top-quartile energy prices are the foremost moats now. Hashpower is changing into institutionalized, with zero-percent converts, together with giant Bitcoin treasuries, blurring the line between miners and structured Bitcoin funds.
CleanSpark is successfully borrowing in opposition to future mining capability and Bitcoin holdings, treating the operation as infrastructure-backed financing moderately than a speculative enterprise capital funding.
That’s not about survival capital. It’s the price of entry to being structurally related in a one-zettahash world.
The miners who can’t entry this type of capital are getting acquired or shut down. Every greenback now has to clear a a lot increased hurdle than “hashrate goes up.” The narrative is tidy, and the money flows will inform the actual story.
