IREN expands its AI data center pipeline to 5.8 GW and signs a $3.4b multi-year partnership with Nvidia, shifting its business model toward large-scale AI infrastructure.

What happened: IREN has grown its global data center development pipeline to 5.8 GW and entered a multi-year, $3.4b partnership with Nvidia to supply AI infrastructure. The company already works with Microsoft and is now adding Nvidia as a major customer alongside its existing relationships.

Why it matters: These moves signal a shift from IREN as a niche player to a scaled AI data center platform serving multiple large customers. The story now centers on execution—how quickly the company can fund, build, and secure contracts for this expanded capacity across different regions, since investor appetite has already driven the stock up 20.7% year to date despite recent weekly and monthly declines.

What to watch: The key questions are capital needs and speed of converting new capacity into contracted revenue. The analyst consensus target sits at US$81.07, while the stock currently trades at US$51.52, about 36% below that level. Debt coverage and shareholder dilution are flagged as risks that matter more as capital requirements increase for the buildout.
