Shares of IREN saw a remarkable surge to an all-time high on Monday following the announcement of a monumental $9.7 billion partnership with Microsoft. The Australian Bitcoin miner and data center company experienced an impressive rise, with shares climbing over 8% to around $66, peaking at an intraday high of $75.73 earlier in the trading session. In contrast, Microsoft’s shares remained relatively stable.
The pivotal deal will enable Microsoft to utilize Nvidia chips in its data centers over the next five years. IREN is concurrently making a significant investment of approximately $5.8 billion to acquire related Nvidia chips and ancillary equipment from Dell Technologies.
To finance these substantial capital expenditures, IREN plans to leverage a combination of existing cash reserves, customer prepayments, ongoing cash flows, and other financing initiatives.
This strategic shift is significant, as IREN, like several other Bitcoin mining companies, is increasingly focusing its operations on the burgeoning demand for artificial intelligence infrastructure. Co-founder and CEO Daniel Roberts expressed enthusiasm about the agreement with Microsoft, describing it as “another major step forward for IREN as we continue to expand large-scale GPU deployments across our 3GW secured power portfolio in North America.”
With the gains realized on Monday, IREN shares have skyrocketed nearly 600% for the year, reflecting the company’s successful pivot and the growing investor interest in AI-driven technologies and infrastructure.
