IREN secures Nvidia B300 and GB300 GPUs for AI cloud businesses

Data center and cryptomine firm IREN has secured more GPUs, taking its tally of chips to almost 11,000.

The company (also known as Iris Energy) this week announced it had secured a further 1,200 air-cooled Nvidia B300s and 1,200 liquid-cooled GB300s for approximately $168 million.

The latest acquisition takes IREN’s GPU fleet to 10,900. The newly acquired GPUs will be installed in the coming months at the company’s Prince George campus in British Columbia, Canada, where construction is underway on a 10MW (IT load) liquid-cooled installation capable of supporting more than 4,500 GB300s.

IREN has secured approximately $96m in financing to support the purchase of the GB300s. The financing is structured as a 24-month lease and represents 100 percent of the purchase price, with lease payments calculated utilizing a high single-digit interest rate. The B300 GPUs are funded from existing cash, with further financing workstreams underway.

“We are pleased to have secured NVIDIA Preferred Partner status and additional non-dilutive GPU financing, enabling us to expand our cloud offering with liquid-cooled, next-generation Nvidia GB300 NVL72 systems,” said Daniel Roberts, co-founder & co-CEO of IREN.

“Supporting both liquid-cooled and air-cooled systems within the same data center campus highlights the versatility of our data center platform – underpinned by nearly 3GW of grid-connected power and scalable to hundreds of thousands of GPUs.”

It is the second GPU purchase announcement IREN has made this month. The company recently announced the purchase of 4,200 Blackwell B200 GPUs, again to be installed at the Prince George site.

The B300 and GB300 NVL72 Systems add to IREN’s fleet of GPUs, which now consists of 800 H100s, 1,100 H200s, 5,400 B200s, 2,400 B300s, and 1,200 GB300s.

IREN currently boasts six data centers across North America, with a total capacity of 2,910MW. The company is in the midst of a pivot away from cryptomining towards its AI cloud business. While it is still mining Bitcoin, the firm is winding down its mining operations and diverting cash flow to its AI business.
