IREN Plans Up to $30 Billion AI Buildout as Nvidia Backs Compute Scarcity Bet

The top five US hyperscalers are projecting a combined capital expenditure of $660 billion to $725 billion for 2026, nearly double their 2025 outlays, as the AI build-out shifts from software to physical infrastructure. Microsoft is guiding for roughly $175 billion in adjusted capital expenditure for both FY2026 and FY2027, with two-thirds of quarterly spend going to short-lived assets like CPUs and GPUs and the rest to long-lived data center infrastructure, and it added 1 gigawatt of capacity in Q3 FY2026, doubling its global footprint in two years. Amazon AWS has raised its 2026 capex guidance to approximately $220 billion, with CEO Andy Jassy saying AI capacity is expected to remain constrained through 2027 and contracted demand extending into 2028. Meta saw profit drop 14% in Q2 2026 despite a 28% revenue increase as its build-out, including a 1 gigawatt data center in Ohio and a Louisiana facility that could scale to 5 gigawatts, compressed margins, while Alphabet raised its 2026 capex guidance to as much as $205 billion and its Google Cloud backlog more than doubled year-over-year to $240 billion. The Stargate joint venture involving Oracle, OpenAI and others targets up to $500 billion in infrastructure investment by 2029, and Oracle's FY2026 capex reached $55.7 billion, more than doubling from the previous year.

IREN's fair value estimate has been trimmed from US$80.93 to US$79.03, a modest adjustment reflecting a mix of growing AI cloud contracts and ongoing questions around execution and supply build out through 2027. The revision lifts revenue growth assumptions to 168.01% from 125.79% and net profit margin expectations to 11.73% from 5.79%, while the future P/E assumption drops to 31.26x from 90.29x and the discount rate rises to 9.41% from 8.83%. On the bullish side, JPMorgan shifted IREN from Underweight to Overweight with a US$65 price target, citing a partnership with Nvidia, new customer signings and higher industry pricing, while H.C. Wainwright raised its target to US$90 after IREN announced US$2.8b of new multi year AI cloud contracts and lifted its 2026 AI cloud annual recurring revenue target to more than US$4b. Northland initiated IREN at Outperform with a US$99 price target, and Freedom Capital upgraded the stock from Hold to Buy. Freedom Capital nonetheless flagged execution on supply additions over the next two years as a central risk, noting the story depends heavily on adding capacity on schedule.
