Iris Energy

Iris Energy (IREN, formerly Iris Energy Limited) has pulled off perhaps the most spectacular strategic transformation in the entire bitcoin mining industry in 2026. From a pure crypto miner in Australia and Canada, in 12 months it has become an AI/HPC infrastructure player whose Q1 FY26 numbers (reported early May) set industry-wide benchmarks: revenue $240.3M (+355% YoY), net income $384.6M (from -$51.7M loss prior year), adjusted EBITDA $91.7M (+3,568% YoY).

The decisive trigger came in January 2026: a Microsoft multi-year contract deploying 76,000 NVIDIA GB300 GPUs across 200MW of critical IT load at the Childress, Texas campus. Microsoft is essentially using IREN as one of its first external Azure AI training facilities outside Microsoft-owned datacenters — a vote of confidence that would have been unthinkable 18 months ago. In parallel, IREN signed multi-year contracts with Together AI, Fluidstack and Fireworks AI.

The result: IREN is targeting $3.4B in AI Cloud annualized run-rate revenue (ARR) by end of 2026, with an expansion to 140,000 GPUs. The market already attributes 90% of today's $18.9B market cap to the AI/HPC contracts — bitcoin mining is just the cash-cow tail funding the CapEx buildout.

IREN is not in the US smart-money 13F universe of Buffett, Burry, or Druckenmiller — the stock was long classified as a 'speculative bitcoin mining bet' and only got onto Tier-1 hedge fund radar after the Microsoft deal in early 2026. That will change materially in the Q2 2026 13F filings (August).

What's already visible: short interest at 16.87% — historically high and a classic short-squeeze setup if AI bullishness keeps building. The institutional holder picture is dominated by BlackRock, Vanguard, and Fidelity (each ~5-8% of float via ETF vehicles), plus AI/tech-focused active funds like ARK Invest (Cathie Wood had IREN as a top-10 ARKK holding through 2025).

Insider activity: CEO Daniel Roberts and CFO Belinda Nucifora have made no unusual sales in 2025/2026 — both built their positions via stock comp. Co-founder brothers Daniel and Will Roberts together hold roughly 15% — strong founder float for a US-listed mid-cap.

IREN currently trades at a trailing P/E of 68.75× (forward negative due to massive capex), EV/EBITDA of 153.71× (TTM) and a PEG of 3.11. On a trailing TTM basis, all multiples look astronomical — but that's the wrong lens because IREN just transitioned from bitcoin mining to AI cloud. Forward EV / run-rate EBITDA based on $700-900M end-2026 EBITDA assumption: 25-30× — fair for a hyper-growing AI infrastructure play. Analyst consensus (14 analysts): target $74.07, range $41-105, 'buy' median. That's +40% upside from $52.94. On full AI cloud ARR realization in 2027, bull cases (Cantor Fitzgerald, JPM AI team) see targets at $120-150. Bear case (Microsoft contract delays): $25-30. Asymmetric setup with high risk.

1. August 2026: Q4 FY26 earnings (IREN's FY-end is June) — market expects first $750M of AI Cloud quarterly revenue as proof of the $3.4B ARR trajectory
2. September-December 2026: Microsoft Horizon-1 datacenter go-live — 200MW critical IT load operational; next major inflection point for the ARR sprint
3. Q1 2027: 13F filings could show Tier-1 hedge fund purchases — IREN as a potential top-10 holding at Tiger Global / Coatue / D1; would be a massive sentiment switch

IREN is the most interesting asymmetric AI infrastructure bet outside of NVIDIA and CoreWeave in 2026. Microsoft anchor contract is investment-grade, the $3.4B ARR target is ambitious but not absurd, and EV/forward ARR of ~6× is cheap versus comps (CoreWeave/CRWV trades at 10-12×). My personal maximum position size here would be 1-2% of portfolio — the 4.18 beta won't allow more without sleepless nights. Stop-loss trigger: any Microsoft contract delay note or spot GPU pricing crash below $1.50/h. Profit-take trigger: stock above $90 with full Q4 target realization. Mid-2027 IREN could be at $130 or at $20 — the range is real. Not for buy-and-forget portfolios.
