IREN은 2GW 규모의 스위트워터 허브에 대한 ERCOT 연계 조건부 승인 소식을 받아 주가가 7% 급등했으며, 애플라이드 디지털도 유사한 호재로 6% 상승했다.
Texas has granted IREN Limited (NASDAQ:IREN) a rare grid milestone that its chief executive describes as the scarcest input in the entire artificial intelligence buildout, prompting an immediate market reaction. The company announced that its 2-gigawatt Sweetwater Hub cleared a key early step in the state’s queue for very large power users—a permitting checkpoint that carries significant weight across the AI infrastructure sector.
In Tuesday morning trading, IREN shares rose 7% to $47.83, lifting its year-to-date gain to 27%. Applied Digital (NASDAQ:APLD) climbed 6% to $27.82 in sympathy with the AI data center trade. Broader market indicators showed mixed signals: the Global X Data Center & Digital Infrastructure ETF (NASDAQ:DTCR) advanced 1%, while the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) fell 0.47%, indicating that today’s move was driven by company-specific catalysts rather than broad tape momentum.
According to IREN, the Sweetwater Hub was conditionally classified as Base Load within the Electric Reliability Council of Texas (ERCOT) Batch Zero process. This early review stage applies to facilities projected to draw substantial electricity, and securing ERCOT status is a mandatory prerequisite for any data center to connect to the Texas grid. Clearing this checkpoint materially advances the project’s timeline, though the classification remains conditional and subject to further regulatory approvals. IREN also noted that additional large-scale projects have entered the Batch Zero process, though it did not disclose their identities. The Sweetwater Hub sits within the company’s announced global development portfolio, which exceeds 5 gigawatts.
Grid interconnection has emerged as the primary bottleneck in the AI compute expansion. While capital for AI data centers remains abundant, grid access is increasingly rationed, making queue positions at live Texas nodes arguably the scarcer asset. On the fiscal 2026 earnings call, CEO Daniel Roberts stated, “New grid capacity is the scarcest input in this entire industry.” IREN reported that active pricing discussions are currently running near $25 million per megawatt of IT load. Applied Digital CEO Wes Cummins echoed this assessment, describing power as “the single most valuable and constrained resource in our industry,” while noting that hyperscaler capital expenditure has reportedly climbed to nearly $700 billion.
The bull case for IREN rests on its target of $4 billion in contracted annual recurring revenue (ARR) by year-end, a grid pipeline exceeding five gigawatts, and a $14 billion pool of committed GPU financing and prepayments. However, investors should note that Batch Zero inclusion is conditional and potentially reversible. Today’s sharp move stands out against a year-to-date performance that remained relatively contained until recent weeks. Additionally, IREN’s fourth quarter of fiscal 2026 GAAP net loss totaled $684 million, which included a $450.4 million non-cash impairment on decommissioned Bitcoin mining hardware, underscoring the transition costs associated with pivoting from cryptocurrency mining to AI cloud services.
Given the headline volatility surrounding a conditional regulatory step, investors calibrating their exposure may wish to maintain modest positions. The broader ecosystem of grid, power, and cooling companies supporting the AI buildout was detailed in a complimentary report on AI suppliers that are not chipmakers, a category that squarely encompasses IREN’s current trajectory.
