Applied Digital Sinks 7%, IREN Tumbles 13% as Data Center Selloff Broadens Past One Name
IREN (NASDAQ:IREN) fell 13% after a $639M impairment charge, dragging down Applied Digital (NASDAQ:APLD) 7%, TeraWulf (NASDAQ:WULF) 7%, and Core Scientific (NASDAQ:CORZ) 7%. IREN's revenue rose 41.1%, but net loss widened due to the impairment. Applied Digital reported $36B in contracted lease value. The selloff is concentrated in capex-heavy AI data center stocks, not broader infrastructure.
