IREN Closes $3 Billion Convertible Notes Offering to Fuel AI Infrastructure Growth
IREN Limited has successfully closed a massive $3 billion convertible senior notes offering. The Bitcoin mining company raised approximately $2.96 billion in net proceeds as it accelerates its shift into AI cloud infrastructure.
Offering Details
The deal was initially sized at $2.6 billion, with the full $400 million greenshoe option exercised. The notes carry a low 1.00% coupon, mature in 2033, and were sold at a 32.5% conversion premium.
The offering was conducted as a Rule 144A private placement to qualified institutional buyers. IREN used $201.3 million of the proceeds for capped call transactions to limit share dilution, with the rest allocated to general corporate purposes and working capital.
Major AI Expansion Moves
This capital raise supports IREN’s aggressive diversification beyond Bitcoin mining into high-growth AI infrastructure:
- $9.7 billion AI cloud hosting agreement with Microsoft (November 2025)
- Strategic partnership with Nvidia to deploy up to 5 gigawatts of AI data-center capacity
- $625 million all-stock acquisition of Mirantis to strengthen its full-stack AI cloud platform
These deals have significantly boosted investor confidence, with analysts raising price targets following the announcements.
Strategic Importance
The new funding provides IREN with strong financial flexibility as it invests over $9 billion in GPU and AI data-center expansion. The company aims to become a vertically integrated AI cloud provider while continuing its Bitcoin mining operations.
Market analysts estimate that listed Bitcoin miners have announced over $70 billion in cumulative AI contracts, with some expected to generate up to 70% of their revenue from AI by the end of 2026.
