The Nevada-based Bitcoin miner, CleanSpark, plans to raise $1.15 billion through a sale of convertible senior notes to fund its expansion into AI and data center infrastructure. The company said the notes will mature in 2032, marking its largest financing yet.
CleanSpark will allocate about $460 million of the proceeds to repurchase shares, while the remainder will support new projects, land acquisitions, and repayment of existing credit lines. The company also granted underwriters an option to purchase an additional $200 million in notes, depending on investor demand.
Raising Capital for a Broader Future
The proposed notes mature in 2032 and carry a conversion premium of 27.5% to 32.5%, allowing investors to exchange debt for stock at a premium to current trading levels. CleanSpark’s announced offer carries no coupon or accretion, meaning holders profit through conversion alone. The structure appeals to investors seeking long-term exposure to the company’s growth strategy rather than fixed income.
Of the $1.15 billion raised, about $460 million will fund share repurchases. The remainder will go toward AI data center expansion, land acquisitions, and debt repayment. The firm expects the sale to price before markets open in New York, according to people familiar with the transaction. Cantor Fitzgerald and BTIG are managing the offering.
Market reaction came quickly. CleanSpark’s shares fell around 5% after the announcement, a common pattern for companies issuing convertible notes. Still, the deal indicates confidence in the firm’s ability to pivot its energy-intensive mining operations toward compute-heavy AI infrastructure.
Behind Mining’s Collective Turn Toward AI
CleanSpark’s strategy mirrors a clear trend across the mining industry, where miners are transforming their facilities into multipurpose compute centers that support blockchain validation and artificial intelligence workloads.
Over the past year, CleanSpark has steadily repositioned itself for that shift. The company raised $650 million through a similar offering last year to expand its mining and energy assets.
More recently, it acquired 271 acres in Austin County, Texas, to develop a new data center campus. The purchase increased its power under contract by 28%, a move that provides the capacity needed for AI training and high-performance computing.
To strengthen its leadership team, CleanSpark hired Jeffrey Thomas as Senior Vice President of AI Data Centers in October. Thomas, a veteran in AI infrastructure, now leads development of facilities in Georgia and Texas aimed at serving enterprise-level compute demand.
CleanSpark isn’t the only Bitcoin mining company pivoting to AI. Several other miners are following the same path.
- HIVE Digital Technologies is redirecting its focus from Bitcoin mining toward AI infrastructure, investing heavily in Nvidia GPU clusters to expand its AI capacity while maintaining renewable energy operations in Canada, Sweden, and Paraguay.
- IREN Limited has made a decisive pivot to AI-ready data centers. It secured a landmark multi-year cloud services agreement with Microsoft to provide access to NVIDIA GB300 AI GPUs at its Texas campus. The company is actively procuring the necessary GPU hardware and is on track to achieve significant growth in its AI Cloud annualized recurring revenue.
- Companies like TeraWulf, Cipher Mining Technologies, Hut 8, and Applied Digital are also making the strategic shift, using their existing data center infrastructure and power capacity for AI.
Why The Move Matters
CleanSpark’s move offers a two-fold signal. On one hand, the scale of the convertible issuance reflects investor appetite for infrastructure plays tied to compute and data-centre growth. On the other hand, the commitment of nearly half a billion dollars to stock repurchases underscores management’s confidence in the company’s value and its transition.
As mining profitability diminishes under elevated difficulty and shrinking rewards, capturing the economics of adjacent compute markets becomes more attractive. The deal may also set a precedent. Other miners with access to cheap energy might leverage convertible debt to morph into dual-purpose operators — mining and HPC/AI.
