IREN Ltd, the Australian data center operator, is witnessing a 5.01% surge in pre-market trading on Wednesday, continuing its impressive rally from Tuesday's 6.17% gain. This upward momentum is primarily driven by the company's recent $9.7 billion GPU cloud services contract with Microsoft and its successful transition from Bitcoin mining to AI data center operations.

The multi-year agreement with Microsoft, one of the largest in the AI infrastructure sector, involves IREN supplying Nvidia GB300 GPUs and is backed by a substantial prepayment. Additionally, IREN has secured a $5.8 billion partnership with Dell Technologies for equipment. These deals are viewed as critical validations of IREN's strategic pivot into the AI space, potentially attracting more high-profile clients in the future. Adding to the positive sentiment, CNBC's Jim Cramer publicly reversed his previous skepticism about IREN, declaring that his past doubts are now "irrelevant" due to overwhelming demand in the booming artificial intelligence sector.

As IREN prepares to report its quarterly earnings later today, analysts expect the company to post a significant 333% increase in revenue to $235.5 million, with earnings estimated at 16 cents per share. Wall Street analysts have responded positively to recent developments, with Roth MKM's Darren Aftahi raising his price target for IREN from $82 to $94. The stock's year-to-date performance shows a staggering 547.71% increase, reflecting the market's growing appetite for AI-related investments and IREN's strong positioning in the AI infrastructure market.
