AI infrastructure race heats up as IREN pitches full-stack strategy, WhiteFiber lands $160M deal

IREN (IREN) co-founder Daniel Roberts outlined an ambitious vision for the company as a vertically integrated AI infrastructure platform in a lengthy X post on Friday, arguing that the biggest bottleneck in artificial intelligence is no longer chips, but physical infrastructure.

“AI demand grows exponentially. Infrastructure doesn’t,” Roberts wrote, pointing to growing constraints around power, land, cooling and data center construction.
Roberts said IREN’s strategy is built around three layers: physical infrastructure such as power and data centers, compute infrastructure including NVIDIA GPUs and servers, and enterprise software and operational tooling.

“Layers 1 and 2 are where the overwhelming majority of IREN’s value is being created today,” Roberts wrote. “Layer 3 is where that advantage compounds further over time.”

The company, formerly known as Iris Energy, has expanded beyond bitcoin mining into AI infrastructure, a wider trend that has been seen in the industry, with projects spanning Texas, British Columbia, Oklahoma, Spain and Australia. Roberts said IREN has secured roughly 5 gigawatts of grid-connected capacity globally.

He argued that owning the full stack creates a long-term competitive moat as AI demand accelerates globally, particularly in underserved regions such as Europe and Asia-Pacific.

The thread also highlighted IREN’s growing relationship with NVIDIA (NVDA), including a recently announced five-year, $3.4 billion AI cloud contract tied to Blackwell GPU deployments in Texas.

Separately, WhiteFiber (WYFI) announced a five-year AI compute agreement worth more than $160 million with an investment-grade technology customer in France. The deployment will use NVIDIA GPUs and expand WhiteFiber’s European footprint.

WhiteFiber provides AI cloud and high-performance compute services using third-party data center infrastructure, while IREN focuses on owning and operating the underlying infrastructure itself.

WYFI shares rose 22% Thursday and gained another 5% in Friday premarket trading, while IREN shares gained 10% on Thursday.
