IREN's lack of transparency on its biggest contract makes it hard to underwrite. It signed a multi-year deal with a leading frontier AI lab without naming the lab or the value, so the credit risk could be OpenAI's or a far weaker lab's. Nebius names and sizes its deals with Microsoft, Meta and Reflection. NDAs are usually the customer's demand, but the thesis rests on contracted revenue converting while IREN lost $684 million last quarter and funds its buildout partly through a $6 billion ATM. x.comÂ
