IREN Completes $3 Billion Convertible Notes Offering to Fund AI Infrastructure Expansion

IREN Limited has successfully closed a $3 billion convertible senior notes offering, netting approximately $2.96 billion in proceeds as the Bitcoin mining company accelerates its transformation into a vertically integrated AI cloud infrastructure provider.

The offering, which initially targeted $2.6 billion, saw the full $400 million greenshoe option exercised according to official disclosures. The notes feature a 1.00% coupon rate, mature in 2033, and were sold at a 32.5% conversion premium through a Rule 144A private placement exclusively to qualified institutional buyers.

Dilution Protection and Capital Structure

Alongside the offering, IREN entered into capped call transactions that establish a cap price of $110.30 per share, representing a 100% premium over the company's last reported sale price of $55.15 on May 11. This mechanism is designed to mitigate shareholder dilution upon note conversion up to that threshold. Beyond the cap price, dilution and potential cash payment obligations would resume.

Of the net proceeds, $201.3 million was allocated to fund the capped call transactions, with remaining capital earmarked for general corporate purposes and working capital requirements. In a related move, IREN terminated a portion of capped call transactions associated with its existing 3.50% convertible notes due 2029, which were partially equitized in November 2025, unwinding the corresponding hedge concurrent with the new offering.

The syndicate of bookrunners included J.P. Morgan Securities, Goldman Sachs, Citigroup, Jefferies, MUFG Securities Americas, Wells Fargo Securities, and Cantor Fitzgerald.

Strategic Pivot to AI Infrastructure

The capital raise arrives as IREN expands aggressively beyond traditional Bitcoin mining operations into AI cloud infrastructure. In November 2025, the company announced a $9.7 billion AI cloud hosting agreement with Microsoft, a deal that drove shares up nearly 30% and prompted Bernstein analysts to triple their price target.

Early May brought another major partnership as IREN forged a strategic alliance with Nvidia to deploy up to 5 gigawatts of AI data-center capacity globally. Under terms of that agreement, Nvidia received warrants potentially valued at $2.1 billion. The announcement pushed Bernstein to establish a $100 price target for the stock.

Days later, IREN completed a $625 million all-stock acquisition of software services provider Mirantis, adding comprehensive full-stack software capabilities to its evolving AI cloud platform.

Balance Sheet Considerations

JPMorgan previously cautioned that IREN's planned GPU and AI data-center capital expenditures—exceeding $9 billion in aggregate—could create near-term balance-sheet pressure. The newly secured financing provides critical capital as the company scales these ambitious infrastructure initiatives.

The transformation underway at IREN reflects broader industry trends. CoinShares estimated earlier this year that more than $70 billion in cumulative AI contracts have been announced across publicly listed mining companies, with some operators projected to generate as much as 70% of their revenue from AI operations by the end of 2026, as previously reported by The Block.

The successful completion of this $3 billion offering positions IREN to continue its rapid buildout of AI infrastructure while managing the capital intensity of its strategic pivot away from pure-play Bitcoin mining operations.
