IREN's Texas Grid Breakthrough Arrives as a $30 Billion Spending Plan Splits the Market

IREN gains conditional base-load status for its 2GW Sweetwater hub, boosting shares 10% as AI data center grid access becomes a key bottleneck.

The race to secure electricity for AI data centers has produced an unlikely bottleneck: the grid connection itself. IREN cleared a critical hurdle this week when ERCOT, the Texas grid operator, granted conditional base-load status to the company's 2-gigawatt Sweetwater hub — a designation that has become increasingly decisive in determining which infrastructure players can actually deliver on their capacity promises.

The market responded swiftly. IREN shares climbed 10 percent to €41.20 in Tuesday trading, following a close of €37.30 the prior session. The stock has now gained 22 percent over the past 30 days, though it remains roughly 40 percent below its 52-week high of €68.61 reached in November.

A Two-Part Project Reaches a Pivotal Stage

Sweetwater is structured as two distinct sub-projects: Sweetwater 1, carrying 1,400 megawatts of capacity, and Sweetwater 2, adding another 600 megawatts. The substation for Sweetwater 1 came online in early May, with an additional 300 megawatts under construction and slated for delivery in the fourth quarter of 2027. The hub forms part of a global portfolio exceeding 5 gigawatts that IREN has assembled.

The conditional base-load classification from ERCOT signals that IREN occupies a privileged position in the scramble for Texas grid access — a factor that increasingly determines competitive viability as power supply tightens for data center operators. Co-CEO Daniel Roberts framed the challenge bluntly: new grid capacity has become the scarcest commodity of all, more constrained than chips or capital.

The designation is not unique to IREN. Soluna received a similar conditional base-load status from ERCOT for its 166-megawatt Kati campus, underscoring how grid classification has emerged as a critical chokepoint industry-wide.

The Repricing Story Behind the Headlines

While the grid milestone dominated the news, a quieter transformation is underway in IREN's commercial pipeline. Current negotiations are reportedly fetching around $25 million per megawatt of IT load — a dramatic escalation from the $9.70 million recorded in November 2025 and the $11.33 million seen in May 2026. Three-year contract prices have more than doubled since November, while five-year agreements have risen roughly 70 percent.

This repricing dynamic is landing on a growing order book. The annualized contract value from IREN's agreements with Microsoft and NVIDIA totals approximately $2.62 billion, and management is targeting $4 billion in contracted annual revenue by the end of December 2026.

The fourth fiscal quarter saw AI cloud revenue double to $70.5 million, while the full year brought that segment to $128.8 million — an eightfold increase year over year. The company also posted a GAAP net loss of $684 million for the quarter, driven largely by a $450.4 million impairment charge that weighs on the balance sheet without diminishing the operational growth narrative.

The $30 Billion Question

The more contentious development centers on IREN's capital expenditure plan of up to $30 billion for fiscal 2027, aimed at expanding its AI cloud business. That figure initially rattled investors, particularly given the recent net loss. Bernstein analysts, however, push back on the pessimistic reading: GPU investment payback periods have reportedly compressed to roughly two years, down from about three years under the earlier Microsoft contract.

The operational data supplies ammunition to both camps. AI cloud revenue has grown nearly eightfold within a year, while the legacy Bitcoin mining operation also posted double-digit gains. Management points to an expected jump in recurring annual revenue to over $4 billion by the December quarter, a meaningful portion supported by an NVIDIA cloud contract scheduled to begin in 2027. The majority of analysts maintain buy ratings, though price targets diverge widely.

What the Grid Decision Means for Investors

The ERCOT classification weaves together two central threads of the IREN story: the physical expansion of infrastructure and the commercial appreciation of computing capacity. Without assured grid access, the company's ambitious capacity plans would struggle to materialize — and the conditional base-load status represents a milestone that strengthens customer confidence in reliable scaling.

The stock's recent jump suggests the market treats regulatory progress in Texas as immediately relevant to valuation. At the current price of €41.20, the shares have recovered 88 percent from their September low, even while remaining well off November's peak. The juxtaposition captures the broader tension: a company delivering explosive growth rates while asking investors to underwrite capital commitments on a scale that would test even the most patient balance sheet.
