CleanSpark Raises $1.15bn to Fund Bitcoin-AI Expansion

CleanSpark is betting that the future of mining lies not in coins but in compute. The company is raising $1.15 bn to transform itself from a pure-play Bitcoin miner into a diversified AI-powered data-infrastructure company, a pivot that mirrors a broader post-halving shift across the industry.

A miner’s reinvention moment

The halving in April halved block rewards, squeezing even the most efficient operators. CleanSpark’s response has been to lean on its biggest asset: energy. 

The company controls 1.3 GW of power capacity, roughly the output of a large nuclear plant or enough to supply about one million US homes, and is now using that energy not just to mine Bitcoin but to run high-performance compute workloads for the AI sector.

That energy drives a network capable of 46.6 EH/s, or roughly 46 quintillion cryptographic calculations every second. In practical terms, that makes CleanSpark the second-largest Bitcoin miner in the world, behind Marathon Digital, giving it the scale to reallocate power toward AI training and data-centre services when crypto economics tighten.

Investors buy the compute narrative

The raise comes through a convertible bond deal (0.00% Senior Notes due 2032) structured to let investors convert debt into equity if the stock rises. Net proceeds are expected to reach $1.13 bn, or $1.28 bn if fully subscribed. About $460mn will fund share buybacks, while the rest supports the company’s power-and-land expansion, data-centre build-out and repayment of Bitcoin-backed credit lines.

With the bonds carrying no coupon, investors are effectively betting on CleanSpark’s ability to convert cheap energy into profitable compute capacity. For miners, that’s the new holy grail.

Compute is the new commodity

The financing marks one of the largest capital raises in the sector since the halving and signals that public miners can still access deep markets if they tell a credible growth story. 

CleanSpark’s “America’s Bitcoin Miner” tagline may soon undersell what it’s becoming, a vertically integrated power and compute company straddling the fault line between crypto and AI.
