NVIDIA Blackwell: Doubling Down on GPU Fleet and AI Compute Performance

IREN Limited is expanding its GPU fleet with the purchase of 4.2k NVIDIA Blackwell B200 GPUs, doubling its total fleet to 8.5k GPUs. The Blackwell architecture offers improved AI compute performance and energy efficiency. IREN's hashrate grew 326% YoY in Q3, achieving its 50 EH/s target in June, with hardware profit jumping 28.7% MoM to $63.3 million in July. IREN faces competition from Strategy and CleanSpark in the bitcoin mining market.

IREN Limited has announced a significant expansion of its GPU fleet by procuring an additional 4,200 NVIDIA Blackwell B200 GPUs, effectively doubling its total GPU fleet to approximately 8,500 NVIDIA GPUs [1]. This expansion is part of the company's strategic initiative to enhance its AI compute capabilities and energy efficiency.

The Blackwell architecture offers notable improvements in AI compute performance and energy efficiency compared to the Hopper architecture [1]. This technology allows IREN to offer next-generation compute solutions in a supply-constrained market while reducing costs and energy consumption.

The newly acquired GPUs will be installed at IREN’s Prince George campus, which has a dedicated power capacity of 50MW and can support up to 20,000 Blackwell GPUs [1]. The company has already secured $102 million in financing for this purchase, structured as a 36-month lease for 100% of the purchase price of the GPUs [2].

The expansion of IREN’s GPU fleet coincides with impressive growth in its hashrate. In the third quarter of fiscal 2025, IREN's hashrate grew by 326% year-over-year, reaching its 50 EH/s target in June [1]. This growth has significantly contributed to the company’s hardware profit, which jumped 28.7% month-over-month to $63.3 million in July [1].

Despite this growth, IREN faces stiff competition in the bitcoin mining market from companies like Strategy and CleanSpark. Strategy has seen increasing bitcoin yield, reaching 19.7% at the end of the second quarter of 2025 and 25% year-to-date [1]. CleanSpark, on the other hand, produced 2,012 bitcoins in the third quarter of fiscal 2025, a 28% increase year-over-year, with an average revenue per bitcoin of $99,000 [1].

The expansion of IREN’s AI Cloud operations bodes well for the company, which operates 660MW of data centers and is expected to expand up to 910 MW in 2025 [1]. This growth is supported by the company’s strategic use of low-cost renewable energy and efficient data center operations.

IREN’s share price has appreciated by 135.5% year-to-date, outperforming the broader Zacks Finance sector’s return of 12.5% and the Zacks Financial Miscellaneous Services industry’s 5.6% [1]. The company’s forward 12-month price/cash flow ratio stands at 82.39X compared to the industry average of 26.72X [1]. Despite this premium valuation, IREN’s Zacks Consensus Estimate for 2025 earnings remains unchanged at 14 cents per share [1].

In conclusion, IREN Limited’s expansion of its GPU fleet with NVIDIA Blackwell B200 GPUs is a strategic move to enhance its AI compute capabilities and energy efficiency. This expansion, coupled with the company’s impressive hashrate growth and competitive share price performance, positions IREN as a key player in the AI infrastructure and bitcoin mining markets.
