Investor skepticism over AI pivot drags IREN down 41%
IREN Limited lost over 40% of its value in a month as fund managers questioned the capital requirements and execution risks of the data center operator's shift from Bitcoin mining to artificial intelligence hosting.
IREN Limited saw its stock price plummet in the second quarter as the market digested the Australian company's rapid pivot from cryptocurrency mining to artificial intelligence cloud services. The selloff was detailed in the latest investor letter from Fred Alger Management, whose Alger Capital Appreciation Fund holds the data center operator.
The extreme volatility underscores a deep divide in market sentiment regarding the company's future direction. As of July 15, 2026, IREN closed at $38.28 per share, giving it a market capitalization of $13.66 billion. Despite a staggering 95.51% gain over the past 52 weeks, the stock has collapsed by 41.14% in just the last month.
IREN is attempting to repurpose its infrastructure for high-performance computing workloads as AI enters what the broader market describes as an "agentic phase." "Shares detracted from performance during the quarter as investors weighed the company's rapid transition toward AI infrastructure against declining Bitcoin mining revenue, elevated capital needs, and execution risk tied to large data center and GPU deployments," the Alger fund wrote.
This skepticism hit IREN even as the broader technology sector surged. The S&P 500 rose 15.2% in the second quarter, driven largely by optimism surrounding technological advancements and easing geopolitical tensions. The Alger Capital Appreciation Fund outperformed the Russell 1000 Growth Index during this period, aided by its broader information technology and communication services holdings, even as IREN dragged on its returns.
The divergence between IREN's recent collapse and its massive one-year gain highlights the specific capital risks facing infrastructure companies attempting to capture AI demand. While recent AI cloud announcements and strategic partnerships support the long-term thesis, the Alger fund noted that concerns around financing and the pace of the business model transition heavily pressured sentiment.
Institutional interest, however, remains active despite the recent drawdown. The number of hedge funds holding IREN rose to 53 at the end of the first quarter, up from 46 in the prior quarter, suggesting some major investors are still betting on the transition.
