IREN shares drop 5% as Anthropic cloud contract report remains unconfirmed, shaking investor confidence.

IREN's stock fell 5% after a report linking Anthropic as its mystery AI cloud contract customer failed to gain confirmation from either company. The initial surge in shares was driven by speculation, but the lack of contract details and silence from both parties led to a sharp pullback. IREN has confirmed a separate contract with Microsoft, which remains a solid foundation for its AI cloud business. Investors are advised to watch for official confirmation or new contract updates to gauge future stock movement.

Following the fading buzz around Anthropic as a cloud contract partner, Core Scientific's shares also saw a decline. On Pluang, Core Scientific (CORZ) is priced at USD 14.70, down 2.13% as of Oct 13, 2026, 21:01 WIB. The stock is trading closer to its 52-week low of USD 13.57 than its high of USD 29.16, reflecting cautious sentiment among investors in the technology sector.
