Bitcoin mining firm IREN has secured a landmark $9.7 billion deal with Microsoft, signalling a major shift in how crypto mining companies are repositioning themselves amid tightening profit margins. The five-year agreement will see Microsoft gain access to Nvidia GB300 GPUs hosted within IREN’s data centres, effectively transforming part of IREN’s mining infrastructure into AI computing hubs. The deal underscores a broader industry pivot, as miners increasingly transition from traditional crypto operations to supporting the explosive demand for artificial intelligence workloads.
Alongside the Microsoft partnership, IREN has inked an additional $5.8 billion agreement with Dell Technologies to procure GPUs and related hardware. The company plans to fund its capital expenditures through a mix of existing cash reserves, customer prepayments, operational cash flow, and external financing. Together, these deals establish IREN as one of the most prominent players in the AI cloud services space while maintaining its standing as one of the world’s largest Bitcoin miners by realised hashrate.
The market responded enthusiastically to the news, with IREN’s shares surging over 10% after Monday’s market open. Investors appear confident in the company’s strategic evolution, viewing the Microsoft alliance as a crucial step in bridging cryptocurrency mining and the broader AI infrastructure economy.
IREN’s pivot to AI infrastructure, which began in early 2024, mirrors an accelerating trend across the Bitcoin mining sector. As mining rewards shrink and operational costs rise, companies are diversifying into high-performance computing to leverage their existing facilities and access new revenue opportunities. Firms such as HIVE Digital, MARA Holdings, and Riot Platforms have already expanded into AI and data centre operations, signalling an industry-wide transformation.
HIVE Digital was among the first to adopt this model, shifting toward AI and high-performance computing in mid-2023 and generating substantial revenue from the new business line. MARA Holdings introduced an immersion cooling system in 2024 to optimise dense compute workloads, while Riot Platforms began preparing for similar expansion earlier this year. These moves highlight how the sector is adapting to capitalise on the surging global demand for AI processing power.
One of the largest comparable deals came in August when TeraWulf signed a $3.7 billion hosting agreement with AI cloud platform Fluidstack, backed by Google’s parent company, Alphabet. The long-term partnership, featuring a 10-year colocation lease, further emphasises how the lines between Bitcoin mining and AI infrastructure are blurring.
For IREN, the Microsoft and Dell deals mark not just a diversification effort but a redefinition of its business model. By leveraging its established data centre footprint and technical expertise, the company is positioning itself at the intersection of crypto mining and the AI revolution—a convergence that may reshape both industries in the years ahead.
