Bitcoin miner Iren raises nearly $3b in note sale

Iren, a bitcoin miner and AI infrastructure company, has completed a nearly US$3 billion convertible senior notes sale due 2033.

The company lifted its target from US$2 billion over three days on strong investor demand, making it one of the largest such deals by a miner expanding into AI infrastructure.

The 1% notes were priced with a 32.5% conversion premium, implying an initial conversion price of about US$73.07 a share against Iren’s May 11 close of US$55.15, and the stock was down more than 3% in premarket trading.

Iren recently signed a five-year US$3.4 billion AI cloud agreement with Nvidia and said it plans to buy about US$3.5 billion of GPUs and related equipment from Dell.

🧠 Food for thought

Implications, context, and why it matters.

The deal’s structure uses common convertible-bond tools

  • IREN lifted the offering from an initial US$2 billion to US$2.6 billion, then to US$3.0 billion after the over-allotment option was fully exercised 12.
  • It also entered capped call transactions, derivative contracts meant to limit share dilution if the notes convert and to offset some cash payments above principal, up to a set cap price 2.
  • Those transactions started with a cap price of US$110.30 per share, equal to a 100% premium to the last reported sale price of US$55.15 on May 11, 2026. The terms allow later adjustments 2.
  • The notes were sold through a private offering to investors reasonably believed to be qualified institutional buyers under Rule 144A, a US securities rule that lets companies sell privately without full public registration 2.

What the financing says about demand for AI infrastructure

  • The financing fits IREN’s push to run more of its own AI cloud stack, with large data centers, Graphics Processing Unit (GPU) clusters for AI training or inference, plus grid-connected land with power in renewable-rich regions 2.
  • Demand for the convertible debt suggests investors will fund AI infrastructure companies, not only AI model builders.
  • Low-coupon convertible debt like this could give other fast-growing tech companies another way to fund heavy capital spending 3.
