Headline: IREN Raises $3B in Convertible Notes as Microsoft and Nvidia Deals Fuel AI Cloud Push
IREN has closed a $3.0 billion convertible senior notes offering to bankroll its rapid shift from bitcoin mining to large-scale AI cloud infrastructure. The securities carry a 1.00% coupon and mature in 2033; the transaction comprised a $2.6 billion base offering plus a fully exercised $400 million greenshoe, with net proceeds of about $2.96 billion after fees and expenses.
Key deal mechanics and use of proceeds
- IREN will allocate $201.3 million of the proceeds to capped call transactions tied to the notes; the remainder is earmarked for general corporate purposes and working capital.
- The capped calls are intended to limit dilution if the notes convert into equity. The capped call cap price begins at $110.30 per share — roughly 100% above the $55.15 closing price on May 11.
- The notes carry a 32.5% conversion premium and do not include an investor put option except in customary change-of-control scenarios.
- The offering was sold privately to qualified institutional buyers under Rule 144A.
How this ties into IREN’s AI expansion
The raise follows two headline partnerships that have reshaped IREN’s revenue outlook: a five-year, $3.4 billion AI cloud agreement with Nvidia and an earlier $9.7 billion Microsoft contract for GPU cloud infrastructure. Reportedly, Nvidia also received a five-year warrant to buy up to 30 million IREN shares at $70 apiece. Those commitments push IREN’s committed revenue above $15 billion as it accelerates buildout of GPU clusters and data centers for AI training and inference.
From Bitcoin mining to “Neocloud”
Formerly Iris Energy, IREN began as a bitcoin miner and has pivoted toward what it calls a “Neocloud” model — repurposing energy and data-center assets to host GPU-heavy AI workloads. The company emphasizes large-scale, grid-connected sites across North America, Europe and APAC as the backbone for its AI platform.
Investor concerns and company caution
Analysts and investors have flagged funding risk as IREN scales GPU infrastructure, given the capital intensity of AI data centers. The convertible note sale boosts IREN’s cash base for that expansion, but the company noted that plans for use of proceeds are forward-looking and offered no guarantees about ultimate effectiveness after paying for the capped call transactions.
Why crypto readers should care
IREN’s transformation illustrates a broader trend of crypto infrastructure players retooling energy and rack capacity for AI demand — a dynamic that affects energy markets, data-center competition, and the future of specialized bitcoin-mining assets. The sizeable convertible raise and the structure chosen to limit dilution will be watched closely by investors tracking the crossover between crypto-native firms and AI infrastructure providers.
