IREN keeps falling behind Nebius: it misses estimates, its story keeps getting pushed back, and despite its capacity it fails to sign contracts or bring in meaningful revenue. Its management, software and engineering are all weaker, and it has not beaten Nebius on any front in recent years. @SpoonKidnapper counters that IREN is still converting its Canadian sites from bitcoin mining to AI, so ARR doesn't yet reflect where it will be in a quarter or two. x.com 

IREN's predatory management and markedly weaker execution than Nebius make it hard to take seriously while Mike Alfred remains on its board. Barring an oversold bounce, IREN looks cooked big time with more time. x.com  x.com 

Lower leverage puts IREN and especially Nebius in a better position than highly indebted neocloud peers to withstand higher interest rates. Debt plus leases equal 1.9 times IREN's equity and 1.0 times Nebius's, versus 10.3 times for CoreWeave; the comparison also includes colocation providers. x.com  x.com 

IREN's worsening fundamentals warrant patience despite its potential. Trailing free cash flow is -$2.45 billion, net income -$703 million and EPS -$1.64 even as revenue has grown; it needs a catalyst change and a positive trend in fundamentals. x.com 

IREN looks like an absurd management money grab, with compensation that carries zero performance hurdles. x.com 

Open-source models likely wrecked the heavy-capex thesis behind IREN. Debt CDS and falling token prices make the still-bullish view definitely less so. Unlike Roku, a previous long-term hold with a unique, massive user base, low capex and positive free cash flow, IREN lacks a clear path forward; without one, it is better not to hold it. If Warsh remains hawkish, a full exit from IREN is very likely. x.com  x.com 

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. … Show more

IREN's low-margin bare-metal business is being financed on uncontracted future capacity, so rising opex and added financing will pressure it. A Goldman Sachs report now flags exactly that: extra financing supports a material amount of uncontracted capacity, the Secured Power metric IREN touts. Most AI data center leasing models will be pressured in some way, and IREN is the most obvious example. x.com 

IREN and Nebius will need to keep aggressively raising debt and equity to grow toward CoreWeave's installed capacity, and that will eat into profit per share through interest expense or a growing share count. Their balance sheets look prettier than CoreWeave's only because their footprints are much smaller; less debt would just mean heavier dilution. @ZeekTyt counters that customer prepayments and GPU loans cover much of IREN's chip cost, keeping its debt far smaller relative to assets. x.com  … Show more

Nebius looks preferable to IREN because its dilution and financing costs are more manageable and it alone has positive retained earnings in this comparison. Nebius's share count rose 18% year over year against IREN's 51%, the highest in the table and, in this view, not put to good use. Nebius's positive earnings include a subsidiary valuation gain despite an operating loss in H1. x.com
