IREN Limited (NASDAQ:IREN) shares rose 3.6% in premarket trading on Monday after the company was added to the Russell 1000 Index as part of FTSE Russell’s annual index reconstitution, which became effective after the market closed on 26 June.
The Russell 1000 tracks approximately 1,000 of the largest publicly listed U.S. companies by market capitalisation and is widely followed by institutional investors as a benchmark for large-cap equities.
Index Inclusion Reflects Continued Growth
IREN’s addition follows a period of expansion across its U.S. operations and customer base. Eligibility for the Russell 1000 is determined through inclusion in the broader Russell 3000 Index, which represents the largest publicly traded companies in the U.S. market.
The index family is maintained by FTSE Russell and serves as one of the most widely used benchmarks by investment managers and index-tracking funds.
Expanding AI Cloud Infrastructure
IREN operates as a vertically integrated AI cloud infrastructure provider, supplying large-scale data centres and high-performance computing capacity for artificial intelligence training and inference workloads.
Its platform is supported by a portfolio of grid-connected land and renewable-powered energy assets located across North America, Europe and the Asia-Pacific region, providing the infrastructure needed to support the growing demand for AI computing services.
