WULF

IREN and TeraWulf pursue different AI infrastructure strategies with distinct risk profiles. IREN operates an integrated AI cloud business with $4B in contracted annualized revenues and $1B already operational, while TeraWulf focuses on leasing powered data center capacity under long-term contracts.

IREN trades at a lower forward sales multiple (2.41X vs 8.51X) and demonstrates more immediate commercial progress, though both companies face substantial capital requirements and execution risks. Analysts favor IREN over TeraWulf given its operating revenues and broader customer base.

IREN Limited is expanding liquid-cooled data center infrastructure to support NVIDIA GPUs and meet growing AI computing demand. The company secured three-year contracts generating over $20 million per MW in August 2026, with pricing discussions at $25 million per MW.

AI Cloud Services revenues surged to $128.8 million in fiscal 2026, but the expansion requires substantial capex of $25-$30 billion in fiscal 2027. Competitors like Applied Digital and TeraWulf are also expanding similar infrastructure.

Applied Digital reported Q1 fiscal 2027 revenues surging 322% to $341.9 million, beating estimates, but posted a wider loss per share of 76 cents, missing expectations. Despite a $36 billion contracted revenue base and improving adjusted EBITDA, the company faces challenges from widening GAAP losses, $6.4 billion in debt, heavy capital requirements, and uncertainty around AI demand. The stock trades at a premium valuation of 7.76X sales versus the industry's 2.48X multiple and has underperformed peers over the past year.

An analyst sold Cipher Digital shares to increase positions in Iren, citing Iren's superior per-megawatt contract values, larger pipeline (5.8 gigawatts), and faster capacity deployment (500 MW in 2027 vs. Cipher Digital's 270 MW). Rising megawatt prices and customer prepayments are expected to help Iren offset capital intensity and dilution concerns.

Applied Digital (APLD) has a substantial $36 billion contracted revenue base across 1.41 GW of capacity, with over 600 MW expected online within 12 months. However, the company faces significant financing and construction risks, while competitors Core Scientific and TeraWulf are rapidly narrowing APLD's contracted-revenue lead with $24B and $27B in contracted revenues respectively. APLD carries a Zacks Rank #5 (Strong Sell) rating with a premium valuation and widening projected losses.
