On August 18, IREN Ltd fell 5.01% in regular trading, trading at $42.67/share, with turnover of $6.67 billion. The stock initially surged over 5% in early trading before reversing sharply into negative territory, displaying a classic sell-the-news pattern.

On the news front, IREN recently completed and delivered Horizon 1 — a 50-megawatt AI computing data center facility — to Microsoft, as part of their five-year, $9.7 billion cloud services contract announced in November 2025. The facility features direct-to-chip liquid cooling technology supporting NVIDIA's GB300 NVL72 platform. IREN also achieved NVIDIA Exemplar Cloud status and completed its acquisition of Mirantis to strengthen its AI cloud platform software layer. These multiple catalysts had already driven the stock higher in prior sessions, with concentrated selling pressure emerging after the intraday spike as investors locked in gains.

Additionally, the company is scheduled to release its full fiscal year financial results on August 27, with the approaching earnings window potentially amplifying short-term volatility.
