Shares surged 6.5% to $48.12 as IREN announced the final transformer has arrived at its massive Sweetwater 1 site in West Texas, pushing the 1,400-megawatt facility to the brink of energization. A concurrent 4.4% Bitcoin rally added fuel, but the real story here is whether a company still losing money can successfully convert raw electrical capacity into AI revenue at scale.

A Bitcoin Miner's Biggest Construction Project Hits a Crucial Deadline

Energization of the 1.4 GW Sweetwater 1 site was scheduled for April 2026 , and social media chatter intensified after the delivery of the fourth substation transformer signaled tangible progress.

This phased approach lets IREN begin generating revenue from early megawatts while construction continues on later phases — critical for a company with negative free cash flow near -$575.6 million and an enterprise value around $14.9 billion.

A $9.7 Billion Microsoft Deal Is the Real Anchor — and the Real Pressure

The Microsoft contract deploys GPUs in four phases through 2026, collectively providing 200 MW of computing load, and is expected to contribute roughly $1.94 billion in annual revenue once fully running.

That deal carries projected 85% project-level profit margins. But Sweetwater 1 is separate from the Microsoft campus in Childress — it represents future capacity IREN must still fill with new customers. The company may announce additional contracts in 2026, leveraging 4.5 GW of secured power that remains roughly 90% unutilized even after the Microsoft deal.

The Valuation Already Prices In a Future That Hasn't Arrived

IREN is not cheap: it trades at a price-to-sales ratio near 30.7x and a P/E over 70x, based on roughly $501 million in revenue.

A $6 billion at-the-market stock offering continues to fuel skepticism about dilution — the risk that existing shareholders' stakes get shrunk by new share sales to fund growth.

Wall Street is split: Cantor Fitzgerald cut its target from $82 to $61 but stayed bullish, while Freedom Capital started coverage at $36 with a cautious Hold rating.

Crypto Ties Still Tug at Both Ends

While pivoting to AI, IREN's legacy mining operations still link its stock price to Bitcoin volatility. Today's crypto tailwind helps, but it also reminds investors this stock can swing hard on forces unrelated to data-center execution. Management has called 2026 a "year of proof" — and with earnings due May 13, proof is exactly what shareholders need.
