IREN is trading 4.16% down at $41.38 after investors reacted to CEO Daniel Roberts’s September 14 warning that high-bandwidth memory, data-center construction, and power-connection constraints could limit AI-compute expansion.

  • The report linked IREN’s premarket decline to those supply concerns.
  • Bitcoin is down 4.30% since the previous close and Ethereum 5.97%, adding pressure to crypto-related stocks.
  • Broader weakness from 5.02% Treasury yields and falling technology shares is also weighing on sentiment.
