Key Takeaways
- IREN was added to the Russell 1000 Index effective June 26, 2026, as part of the annual FTSE Russell reconstitution.
- The inclusion reflects IREN's ongoing expansion in the U.S.
IREN Limited (NASDAQ: IREN) and Keel Infrastructure (NASDAQ: KEEL) Corp. were added to major Russell indexes following the latest FTSE Russell reconstitution, extending the visibility of two digital infrastructure companies that have drawn investor attention during the AI data center buildout.
IREN said Monday it was added to the Russell 1000 Index after the market close on June 26. The index tracks roughly 1,000 of the largest U.S. equities by market capitalization and is widely used by investors as a benchmark for large-cap stocks. Membership in the Russell 1000 is based on inclusion in the broader Russell 3000 Index.
Keel Infrastructure, meanwhile, said it was added to the Russell 3000 Index effective at the U.S. market open Monday. The Russell 3000 is designed to represent the broad U.S. equity market and is closely followed by index funds and benchmarked investors.
The additions come after a volatile stretch for AI and energy infrastructure-linked stocks, including companies that have repositioned bitcoin mining sites and power assets for high-performance computing workloads.
