NEW YORK, May 4, 2026, 12:02 (EDT)
Shares of IREN Ltd surged over 10% Monday, after the AI cloud and data-center player announced its Sweetwater 1 facility in Texas hit a major power milestone. The stock last traded at $50.37, up $4.71, following an intraday high of $51.24.
Shares jumped after IREN revealed it had brought its 1.4-gigawatt Sweetwater 1 data center online. With the high-voltage substation now linked to the Electric Reliability Council of Texas, or ERCOT—the state’s primary grid operator—the project has cleared a key milestone ahead of scaling up power and computing.
AI infrastructure investors are chasing scarce assets these days—think land, power, substations, and graphics chips. With IREN’s fiscal third-quarter results set for May 7, the Sweetwater update lands only a few days ahead, teeing up another look at its AI cloud revenue push.
Sweetwater ranks as a major swing asset for the company. According to IREN, the West Texas hub covers 1,800 acres split between Sweetwater 1 and Sweetwater 2, supporting up to 2,000 megawatts of capacity—enough space for more than 700,000 liquid-cooled GPUs. Those are the chips needed for training and running AI models.
Still, there’s more work ahead. Power delivery at Sweetwater 1 will roll out in stages, tied to data center construction and commissioning. Daniel Roberts, IREN’s co-founder and co-CEO, put it this way: “Delivering Sweetwater 1 substation energization on schedule reflects our disciplined execution.” Stock Titan
The milestone reinforces IREN’s claim that its reach goes well beyond hardware. Back in November, the company unveiled a $9.7 billion deal with Microsoft for AI cloud infrastructure built on NVIDIA GB300 chips at its Childress, Texas site. Jonathan Tinter, a Microsoft business development executive, called out IREN’s integrated data center and GPU setup—plus its locked-in power supply—as reasons for the partnership.
IREN has surfaced on watchlists next to CoreWeave and Nebius, both cloud specialists catering to large tech clients hunting for computing muscle. Cipher Digital, usually linked to bitcoin mining, is making moves deeper into AI infrastructure too. TipRanks, in a note last week, lumped CoreWeave, Nebius, and IREN together as “neo-cloud” plays riding the AI investment wave from Microsoft, Amazon, Alphabet, and Meta. The report also spotlighted Amazon’s $5.5 billion deal with Cipher. TipRanks
Views on IREN are split. TipRanks data shows a Moderate Buy consensus—eight analysts rate it Buy, three say Hold, and one recommends Sell over the past three months. The average price target: $73.30. Freedom Capital’s Hold call, highlighted in the same report, points out that IREN’s push to shift from crypto mining to AI cloud infrastructure might drag on longer than the company projects.
Execution’s the sticking point here—not the headline itself. Back in March, a filing revealed IREN could unload as much as $6 billion in ordinary shares using an at-the-market program, which basically means the company can drip new stock into the market at intervals. Sure, that route can bankroll expansion. But if management leans too hard on these sales, current shareholders risk getting watered down.
Sweetwater 1 is being read as a sign that AI’s tightest bottleneck — grid power — is shifting from promise to reality. Now, eyes are turning to IREN and whether it can actually convert that electricity into signed data-center deals on time, keeping financing pressures from running ahead of expansion plans.
