Why Is IREN Stock Down Today? $6B Equity Plan and Nvidia GPU Purchase

Shares of IREN Limited (NASDAQ: IREN) are under pressure on Thursday, March 5, 2026, as investors digest a pair of major announcements from the AI cloud infrastructure company. The stock was trading down roughly 6.57% at $40.96 as of mid-morning, pulling back sharply after closing up 12.8% at $43.84 the prior session.

The dual announcements, a massive at-the-market equity offering and a new agreement to purchase over 50,000 NVIDIA B300 GPUs, sent mixed signals to the market, with the dilution risk from the equity program appearing to outweigh enthusiasm over the GPU expansion.

$6 Billion Equity Offering Rattles Investors

IREN announced an at-the-market equity program of up to $6 billion, to be managed by 11 financial institutions including Goldman Sachs, JPMorgan, and Citi. The company described the program as part of its broader capital management framework, intended to complement existing and new funding sources as it scales its AI infrastructure ambitions.

As of January 30, IREN had approximately 332.3 million shares outstanding, meaning the offering represents a significant potential dilution of existing shareholders — a key reason the stock gave back much of Wednesday’s gains in premarket and continued lower through the morning session.

The equity program comes as IREN looks to fund approximately $3.5 billion in additional capital expenditures expected in the second half of 2026, covering GPUs, servers, storage, networking, labor, and ancillary equipment. The company has already secured $9.3 billion in funding over the past eight months across customer prepayments, convertible notes, GPU leasing, and GPU financing, signaling an aggressive growth posture.

While management framed the ATM program as a disciplined tool within a broader funding mix, markets interpreted the sheer scale of the offering as a near-term headwind for the stock.

IREN Expands AI Cloud With 150,000 Nvidia GPU Fleet

Alongside the equity announcement, IREN revealed it has entered into purchase agreements for over 50,000 NVIDIA B300 GPUs, which will bring its total fleet to 150,000 GPUs. The company plans to deploy the additional hardware in phases through the second half of 2026 across its existing air-cooled data centers in Mackenzie, British Columbia, and Childress, Texas.

The expanded fleet is expected to support an AI Cloud annualized run-rate revenue target of over $3.7 billion by the end of 2026, positioning IREN among the largest AI cloud infrastructure providers globally. Co-Founder and Co-CEO Daniel Roberts emphasized that early procurement is a strategic advantage in the current supply-constrained GPU market, reducing time-to-compute and increasing execution certainty for customers.

Payment terms for the hardware are structured on a post-shipment basis, which the company says enhances working capital efficiency. Existing data center capacity at Canal Flats and Childress provides room to support further GPU additions beyond the current expansion, suggesting IREN is laying the groundwork for continued scaling well into 2027 and beyond.

IREN Stock Brief: Price, Trends, and Key Metrics

As of 10:04 AM EST on March 5, 2026, IREN was trading at $40.96, down $2.88 or approximately 6.57% from its prior close of $43.84. The stock opened at $41.17 and has traded in a day range of $40.40 to $41.88. In premarket trading, the decline was initially reported at 4.2% to around $42, with selling accelerating once the regular session opened.

Despite today’s drop, IREN has delivered a remarkable 1-year return of over 406%, vastly outpacing the S&P 500′s 17.22% gain over the same period, and is up roughly 8% year-to-date. From a valuation standpoint, IREN carries a market cap of approximately $13.5 billion, with a trailing P/E of 28.35 and a forward P/E of 62.50, reflecting high growth expectations priced into the stock. The company’s 52-week range spans from $5.12 to $76.87, underscoring the stock’s high-beta nature, a beta of 4.32 confirms it moves dramatically relative to the broader market.

Analyst sentiment remains broadly positive, with an average price target of $79.46 and a consensus leaning toward Buy, though the current price sits well below that average, suggesting analysts see significant upside if execution on the GPU expansion and revenue targets plays out as planned.
