IREN Limited (IREN) closed Monday's session at $34.80, down 1.11%, before recovering 0.86% to $35.10 in after-hours trading, as reports circulated linking the company to an undisclosed multiyear cloud agreement with Anthropic. The reports renewed market interest in IREN's expanding artificial intelligence infrastructure business, although neither company has confirmed any arrangement.

Report Links Anthropic to Multiyear Cloud Agreement With IREN

The Information reported that Anthropic maintains an unannounced multiyear cloud agreement with IREN, citing people familiar with the arrangement. The report examined Anthropic's efforts to expand data center capacity and meet its growing computing requirements. Neither company has publicly confirmed the partnership, and no financial terms have been disclosed.

The report also connected Anthropic's infrastructure expansion to several companies with backgrounds in Bitcoin mining, including Hut 8, TeraWulf, IREN, and Nscale. These operators provide computing infrastructure alongside access to large power resources, enabling technology companies to expand capacity without developing every facility independently.

A confirmed relationship with Anthropic would support IREN's ongoing transition from cryptocurrency mining toward artificial intelligence cloud services. It could also strengthen the company's position in the growing market for high-performance computing infrastructure. Demand for advanced computing capacity continues to create opportunities for specialized data center operators, and such an agreement would add another prominent customer to IREN's expanding business network.

August Disclosure Fuels Anthropic Speculation

The speculation builds on IREN's own disclosures. During its fiscal fourth-quarter earnings call in August, the company outlined several multiyear cloud agreements. Chief Executive Daniel Roberts identified customers including Cohere, Prometheus, Perplexity, Figure AI, Fal AI, and Higgsfield AI. He also referenced a separate agreement with a leading frontier artificial laboratory, without naming the organization.

That earlier disclosure has created a link between IREN's existing contracts and the latest reporting. The company has not established whether Anthropic represents the previously unnamed laboratory customer or a separate arrangement. As a result, the reported partnership remains an unconfirmed development rather than a newly announced company contract. Any official announcement from either side identifying the customer or the terms would clarify whether the reported Anthropic deal is that earlier agreement or an entirely new one.

Competition and Data Center Scrutiny

IREN has been building out its infrastructure business through agreements with technology companies seeking additional computing capacity, supported by a growing customer network and existing facilities. The company also faces competition from CoreWeave, Nebius, and other operators expanding their own artificial intelligence infrastructure businesses.

At the same time, IREN has faced criticism concerning the operational quality of its older data centers in British Columbia. Research firm SemiAnalysis recently highlighted reported customer complaints involving facilities in Prince George and Mackenzie. Those concerns have brought additional scrutiny of IREN's infrastructure as the company scales its artificial intelligence operations. The scrutiny carries weight because multiyear cloud customers depend on sustained data center performance, making operational quality a competitive consideration for operators courting large artificial intelligence contracts.

Market Reaction Remains Cautious

Retail interest strengthened following the reports connecting IREN with Anthropic. The stock reached the top of Stocktwits' trending list as traders discussed the possible partnership, with some market participants anticipating further gains while others questioned the lack of official confirmation. IREN shares had risen approximately 8% in overnight trading on Sunday on the speculation, before Monday's regular session erased those early gains and finished below the previous closing level.

IREN shares have also struggled against several competing cloud infrastructure stocks during 2026. The company entered Monday's session with a year-to-date decline of approximately 7%, according to the earlier market report. While the Anthropic speculation lifted trading interest, Monday's lower close showed that the initial rally had faded. Until IREN or Anthropic confirms the arrangement, the reported deal remains a press account rather than a disclosed contract.
