$IREN Ltd(IREN)$ The usual comparison in the neocloud space focuses on revenue, backlog, and contracts. But the durable moat in this business is secured, grid-connected power. Multi-year permitting timelines and finite utility capacity make power — not GPUs, not contracts — the actual rate-limiter for the AI buildout.

The asset base tells a different story than the market caps suggest. IREN has 5 GW of secured power at an $18B market cap. Nebius has 4.2 GW (including the new Pennsylvania site) at $45B. CoreWeave has 3.5 GW contracted at $43B. That's roughly $3.6B per GW for IREN, $10.7B for NBIS, and $12.3B for CRWV. IREN trades at about a third of its peers' per-GW valuation while holding the largest secured portfolio.

The obvious counter-argument is that IREN has less contracted revenue than NBIS ($44B+) or CRWV ($99B backlog). That's fair — the market is pricing near-term revenue, not the durable asset base. But power gets monetized across multiple contract cycles. GB300 today, Rubin in 2027, Rubin Ultra in 2028, Feynman beyond. Each NVIDIA generation demands more power density, not less. Whoever holds secured capacity now will be deploying it for the next decade.

Management noted that just 10% of IREN's 5 GW gets them to their $3.7B ARR target by end-2026. The other 90% is runway for future hyperscaler contracts.

NBIS and CRWV are excellent execution stories trading at execution multiples. IREN is the asset story trading at an asset-light multiple. The convertible market noticed first: IREN priced converts at 1.00% recently, versus NBIS at 1.25%–2.625% and CRWV at 1.75% (plus 9.75% straight debt). Smart money is already pricing the asset quality.
